The Japanese military during the 1930s gained almost complete control over the government. The depression of the 1930s hit Japan hard. The militarists decided that the solution to the economic crisis was to carve out an empire. This meant war. Japan withdrew from the League of Nations as a resulted of the criticism of her military operations in Manchuria (1933). Japan invaded China proper, launching the Second Sino-Japanese War (July 1937). The well equipped Japanese forces rapidly occupied almost the entire Chinese coast and then moved up rivers and railroad lines into the interior. The Japanese in the process committed war atrocities on an unpresidented level against the Chinese civilian population. Despite the Japnese onslaught, the Chinese government never surrendered. America funelled supplies to the Chinese through Burma. A covert operation set up the Flying Tigers to provide the Chinese a creditable air capability. Japan joined the Axis powers Germany and Italy which since 1939 had been at war with Britain. Hoping to avoid war in the Pacific, the United States and Britain responded to the Japanese actions with an oil boycott. The Japanese militarists were unwilling to change their policy. The only force standing between the Japanese and thecresources of Southeast Asia was the United States Pacific Fleet and the British garison at Singapore. A Japanese carrier taskforce on December 7, 1941, executed a surprise attack on the American base at Pearl Harbor. It was a brilliant tactical victory for Japan, but perhaps the greatest mistake in modern military history as it brought an instantly united America into the War. The American carrier victory at Midway dealt a severe setback to the previously invincble Imperial fleet (June 1942). American shipyards were turning out the new Essex class carriers that would engage the weakened Imperial Navy in 1944. These carriers permitted the United States to launch a Centralm Pacific offensive (1943) and destroyed the Imperial Fleet (1944). With new island bases wrestled from the Japanese, the United States begins the strategic bombardment of the Japanese Home Islands. The United States dropped two atomic bombs on Hiroshima and Nagasaki on August 6 and 9, 1945 and the Soviet Union entered the war against Japan on August 8. The success of the Soviet Army convinced evebn many hard-line military officers that defeat was inevitable. Emperor Hirohito on August 14 decided to surrender unconditionally. The formal surrender was held underneath the guns of the battleship USS Missouri in Tokyo Bay.

The Pacific War

The Pacific War primarily between America and Japan was only part of Japan's participation in World War II. And it did not absorb the bulk of the Empire's resources. Japan had no way of doing this. The United States in contrast was able to do precisely this. The Imperial Army was primarily committed in China throughout the Pacific World. One might ask why Japan would take on the United States while bogged down in an iterminable war in China, but this is just what the Japanese militarists did. Ironically while the Pacific War is generally seen began with a dazling display of air power and a brilliant burst of nuclear energy, again delivered by air power. It was probably the most illconceived military campaign in humsn history. Japan chose to wage a naval war which mean that its massive army could not be effectively employed to protect the country. This was of no importance as long as the Imperial Navy dominated the Pacific, but given the industrial might of the United States, it was not realistic to think this could last very long and it did not. This left the route to the Home Islands defended by only groups of small islands. And the United Ststes had the resources not only to wage the Pacific War while pursuing an even larger campaign in Europe but to conduct atwo pronged drive to the Home Islands. And this time there would be no Devine Wind this time to destoying an invsding armada. The Japanese faced an insolavle problem. They could only put so many men on the small islands between the Home Islands and the Amedricans. Phyically more were possible, but they had to be fed and provisioned and Japan did not have the capability to do this. This mean that most of the Pacific battles were fought by only a few thousand men--much smaller in scale than the European campaigns. The Japanese soldiers fought to the death, but in every case the Americans took one island after another on the drive to Japan. And once the Marianas were in American hands, the new long range B-29 bombers were able to turn Japan's higly combutable wood and paper cities into burning inefernos.

Japanese Military

The Japanese military during the 1930s gained almost complete control over the government. Civilian politicians attempting to resist the military were assassinated. Communists were persecuted. The military introduced a highly nationalistic indoctrination program in the schools. Censorship of the media was intensified. Navy and army officers occupied most of the key offices in the government, including the office of prime minister. The depression of the 1930s hit Japan hard. The militarists decided that the solution to the economic crisis was to carve out an empire in Manchuria, China, and southeast Asia. This meant war. The Japanese Kwantung Army occupied Manchuria using as a pretext a faked incident on the main railroad (1931). Japan then decalared "Manchukuo" an independent state, Next would be an invasion of China itself. The Japanese proved capable of defeating Chinese armies, but at enornous cost in blood and treasure. At home the Army gradually assumed total control of the Government and with the NAZI move toward war in Europe, debted how best to take advantage of the opportunities presented. The Manchurian-Mongoloian border war with the Soviets chastented the Strike-North faction. The Western powers seemed a softer target and the Dutch East Indies and British Borneo offered badly needed oil. The Army officers like Hideki Tojo had no concept of the oitsude world are how badly that Japan was outclassed by American industrial power. Their concept was to quicjky seize a vast empore in Southeast Asia--the Southern Resource Zone. Presented with a new reality, the Japanese generals who for the most part had no knowledge of America were convinced that the United States would not have the stomache to wage the bloody military campaign needed to oust them. The Japanese decesion is all the more astonishing when one realizes how poorly the Japanese Army was equipped and the lack of millitary competence. There were some stellar figures like General Yamashita. For the most part, however, Japanse Army commanders were unimaginative an largely incompetent. This would be nowhere better exhibited than Guadalcanal, a battle the Japanese could have won. The Imperial Navy has ships of high caliber. And the Japanese had the most effective fighter in the Pacific, but the Army's equipment was of generally poor quality. Its commanders employed unbelievably poor tactics. Even worse by launching the Pacific War, the Army which was concentated in China, hade not way of deploying in strength effectively to impede the U.S. Navy's advance across the Pacific toward the Home Islands.

China (1931-45)

Japan in the late 19th century as it began to develop a modern military, followed the precedent set by Western nations and forced China to sign economical and political treaties. The First Sino-Japnese War (1895) resulted in Japan's seizure of Taiwan. Japan's victory in the Russo-Japanese War (1904-05) strengthened Japan's influence in Manchuria. The Japanese Kwantung Army occupied Manchuria, a Chinese province, using as a pretext a faked incident on the main railroad (1931). Japan then decalared "Manchukuo" an independent state, setting up Pu Yi, the last Manchu Emperor of China as puppet Emperor (1932). Anti-Japanese disturbances broke out in Shanghai. The Japanese bombed the unprotected city to quell the disturbances. This was the first of many Japanese terror bombings of civilian populations. Japan withdrew from the League of Nations as a resulted of the criticism of her military operations in Manchuria and China (1933). Japan invaded China proper in July 1937, launching the Second Sino-Japanese War. The Japanese Kwantung Army turned a small incident into a full scale war. The well equipped Japanese forces rapidly occupied almost the entire coast of China and then moved up rivers and railroad lines into the interior. The Japanese in the process committed war atrocities on an unpresidented level against the Chinese civilian population. The most savage of these explosions of barbarity was the Rape of Nanking, after the fall of the capital Nanking. Here European diplomats and missionaries witnessed the brutality of the Japanese. Despite the Japnese onslaught, the Chinese government never surrendered. America even before entering the war against Japan funelled supplies to the Chinese through Burma. A covert operation set up the Flying Tigers to provide the Chinese a creditable air capability. The Chinese achieved no real military victories, but the Japanese were never able to defeat them. They moved further inland, setting up a new capital Kumintang. The War continued on a lower scale, but envolving the continued deployment of the bulk of the Japanese Army.

Soviet Union (May-September, 1939)

Large scale clashes occurred beginning May 1939 between Japanese and Soviet forces on the Mongolian plains along the border with Japanese-held Manchuria (Manchukuo). Neither side declared war. The Japanese released photographs of captured Soviet soldiers (July 1939). The conflict was little reported in the West. An offensive planned and executed by Marshall Zukov ended in a decisive voctory for the Soviets. The Japanese were forced to seek an armistace (September 1939). The clash was, however, of imense strategic significance, significantly affecting the strategic conduct of World War II. It was undoubtedly a factor encouraging Stalin to respond favorably to NAZI initiatives for a Non-Aggression Pact (August 1939) to ensure that the Soviet Union would not face a two-front war. Hitler ignored the Soviet performance and instread saw the inept Red Army offensive in Finland as evidence that the Soviets could be easily defeated. The Japanese Army concluded that further attacks on the Soviets were unwise. This was an important factor in attacking south in 1941 at America rather than north at the Soviet Union. It was also a major factor in refusing entrities from Hitler in 1942 to attack the Soviet Union, feeing the Red Army from what may have been a disastrous two-front war.

Northern French Indo-China (June 1940)

The war in Europe opened new opportunities for the Japanese. The fall of France to the Germans rendered the French incapable of defending their colonial possessions. Hitler in the Franco-German Armistice (June 1940) allowed the new French Governmeny in occupied Vichy to retain control of its colonies. This meant that the Japanese could move against Indochina. Indochina was important for a variety of reasons. Indochina had some resources, but it was geography that primarily attracted the Japanese interest. Possession of northern Indochina closed one of the last routes through which the Allies, primarily America, could aid China. The Sino-Vietnamese Railway from the port of Haiphong through Hanoi to Kunming in Yunnan was one of the few remaining roures theough whivh the Nationalists could obtain suppies. The Japanese first moved against northern Indochina. Even before the French surrendered to the Germans, the Japanese French Ambassador in Tokyo with a series of demands (June 19). Tokyo demanded that France immediately cease shipment of all war materiel to China and to adnit a Japanese Control Commission to regulate the border with China. Japanese troops massed on the Chinese border with Indochina and Imperial Navy ships sailed into the Gulf of Tonkin to demonstrate that these were no longer requests. The Japanese Government gave the French 48 hours to comply. Fighting lasted several days before the French authorities reached an agreement with the Japanese. The Japanese at the same time demanded that the British cease deliveries of war material to China over the Burma Road. An agreement was finally reached with the new Vichy Government which did not have the capability of resisting the Japanese (August 30). This allowed the Japanese to move military forces into the northern area of French Indochina (1940). A major goal of the Japanese was to cut off the flow of military supplies to China. The Japanese not only achieved that objective, but now could use French airfiekds to bomb Chinese targets. America in response to began to take economic sanctions against Japan.

Axis (September 27, 1940)

The Tripartite Pact was signed September 27, 1940. The agreement allied Germany and Italy (which were at war with Britain) and Japan (which was at war with China). Germany and Italy has since 1939-40 been at war with Britain. Japan since 1937 had been at war with China. The alliance did not require the partners to join these wars, but it did require them to come to each other's aid if attacked. The alliance became known as the Berlin-Rome-Tokyo Axis alliance, or commonly the Axis. The three Axis partners German hegemony over most of urope; Italian hegemony in the Mediterranean, and Japanese hegemony in East Asia. After the Axis agreement was signed, several German allies joined the Axis, notably Vichy France and Fascist Spain refused to do so. Japan had no Asian allies, except or the puppet state of Manchukuo.

Economic Sanctions (July-August 1941)

The aJpanee at first seized only northrn Indochina. The decesion to seize the south as well came with the the German invasion of the Soviet Union (June 1941). With the Soviets hard-pressed in Europe, the Japanese high command finally concluded that a 'Strike South' would solve Japan's resource problems, especially its dependence on the United States for oil. To prepare for an invasion of the oil-rich Dutch East Indies (DEI), some 140,000 Japanese troops invaded southern Indochina (July 28, 1941). Possession of southern Indochina put the Japanese within striking distance of the DEI oil fields and Malya through which they could attack Singapore. Allied cracking of the Japanese Diplmaic Purple code provided Allied leadwrs access to Japanese strategic thinking., but not nval mivements. Still hoping to avoid or delay war in the Pacific, the United States and Britain responded to the Japanese actions with an oil boycott. The result was an oil shortage. The Japanese militarists were unwilling to change their policy of war in China and the oil embargo had the affect of convincing them that they needed to seize the oil rich DEI (Indonesia) to guarantee fiture supplies of oil. The DEI was virtually defenseless, but the small Dutch garison there was loyal to the Dutch Government in exile. The only force standing between the DEI and the Japanese was the United States Pacific Fleet and the British garison at Singapore.

Japanese Carrier Forces (1941)

Japan in 1941 had the largest, most advanced caarier force in the world. The commander of the Imperial Fleet, Admiral Yamamoto, was a proponent of naval aviation. The Imperial Navy had 13 carriers. It was not just that the Japanese had more carriers, but they had higher performance aircraft and more experienced pilots. The carriers had Mitsubishi Zero fighters which out performed any fighters available to either the U.S. Navy or the U.S. army Air Corps had. Japanese carrier pilots went through a rigorous training program. Many had combat experience from operations over China. The Japanese pilots were the most skilled naval aviators in the world. This was not inderstood at the time. The U.S. Navy Pacific fleet had two carriers, Lexington and Yorktown. Rising tensions in the Pacific caused the Navy to shift Enterprise to the Pacific to join them. The significance of this disparity in forces was not fully appreciated in 1941 because most naval planners still considered the battleship to be the capital ship. The japanese carriers tend to be smaller than the American carriers, nut were slightly faster. The carriers themselves did not outclass the American carriers, but several factors made the Japanese carrier force the most powerful and potent naval force in the world. First was deck crew training. The Japanese carriers could launch a major strike in 5 mimites, something that would take the American carriers 30 minites (based on Midway performance). Second was superior aircraft, especialy the Mitsunishi A6M Zreo fighter. The Japanese Nakajima B5N Kate wa aksp far superior to its American counterpart. The Americans has ab excellent dive bomber, nut the Zero gave the Japanese a level of prorection the Americans did not have although their combat control was weak. Third was the superbly trained Japanaese polots. None of this was undersood before the War. Most Western military experts did not consider the Japanese to be capable of building high quality ships or planes or the Japanese to be effective fighters. The aircraft carrier was an offensive weapon. And the Japananese penchant for the offense and combat power was a pefect fit. The carrier force that got in the frst strike was the one likely to prevail. But it also caused the Japanese to fail to give needed attention to damage conrol, both damage control devices and crew training.

Imperial Conference (July 2, 1941)

The Japanese decided on a "southern advance" policy with the understanding that this could lead to war with the United States. Japan had earlier acted to safeguard its northern territories by signing a neutrality pact with the Soviets (April 13, 1941). The NAZI invasion of the Soviet Union (June 22) provided further assurance that there would be no danger of interference from the Soviets if Japan moved south.

National Preconceptions

Rarely in the history of war have two great nations moved toward war with such huge eronious preconceotions about each other. The misconceptions include both individual maters as well as industrial and scientific capabiliies and for the Japanese the importance of industry and science. One very important matter to understand is the importance of race. America in the 1940s was a racist country, but country that was changeing and not a country that was willing to kill on a racial basis. American racism caused the United States to underestimate the Japanese, it did not push America to war. Japan on the other hand was a virulently racist country and this racism led to brutal colonial policies like in Korea and horific attricities like the Rape of Nakig (1937). Racist attitudes led America to view the Japanese as a people small in stature with terrible eyesight. Japanese victories in night time naval battles during the Solomon Campaign (1942) came as a shock to the Americans as did the effectiveness of Japanese aviators during the first year of the War. The Japanese for their part viewed the Americans as soft and whose women would never allow them to fight a long war. The fundamental miscalculation was Japan's failure to understand the full potential of America's industrial an scientific might. America underestimated Japan's industrial capability, but this underestimation was small in comparison of the collosal miscalculation of the Japanese militarists who launched the War.

Japanese Strategic Concept: Barrier and Javelin

Japan by 1941 had arrived at a situation in which its military leaders managed to convince themselves that war with the United States was the only way they could ensuring the long-term security of the Empire. Repulsed in the North by the Red Army and unable to complete the long, expensive conquest of China, the Japanese militarists looked South--the Southern Resource Zone (SRZ). There they saw emense resources, everything Japan needed to complete the conquest of China and feed its industry and people in perpuituity. With thise resources and possesion of China, the Militarists believed that Japan could build an industrial base equal to the great powers. The British, Dutch, and French who controlled the region had only minimal forces in place to protect their colonies. The only thing that stood in their way was the Americans in the Philippines and its Pacufic Fleet that President Roosevelt had moved forward to Pearl Harbor. One historian describes the strategic concept conceived by the Japanese as Barrier and Javelin. [Willmott] This meant Defense and offense. The Japanese decided to seize the SRZ even though it would mean war with the United States. (Naval planners rejected the idea of seizung the SRZ and leaving Americans untouched in the Philippine Islands.) They decided that a crushing victory over the Pacific Fleet would convince America, as it had done to the Russians (1905), to make peace. They conceived of establishing barriers that would make a counter-attack across the Pacific to costly in men and material for the pleasure seeking Americans who like the Russians before them would decide to make peace. The barrier to be constructed shifted over time. Rabaul in the New Heberdies emerged as the major bastion in the south, but the Japanese came to see Australia as their ultimate objective. Truk in the Carolines was the major barrier in he Central Pacific, but as the War progressed the Japanese began to see Midway and ultimately the Hawaiian Islands as their ultimate barrier in the Central Pacific. And the Aleutian Islands became their northern bastion.

Katai Kessen

Kantai Kessen (decisive battle) Doctrine dominated the thinking of the upper echleons of Japanese naval thinking. This was cemented by the great victory of the fledgling Japanese Imperial Navy commanded by Admiral Tōgō Heihachirō over the Russian Fleet in the Tashima Straits (May 1905). It was Japan's Trafalgar, but unlike the British Royal Navy, the Imperial Navy was a very recent creation with few influential traditions. But as Japan embarked onthe Pacific War, Tsushima and Katai Kessen was deeply embedded in the mind of every officer who has passed through the Imperial Japanese Naval Academy located in of all places--Etajima, Hiroshima. (It had been founded in Ngasaki.) Interesting, the U.S. Navy came up with a very similar doctrine -- War Plan Orange. The U.S. Navy had a much longer history, but had never before conducted a major fleet action against a serios enemy fleet. The similar naval plan reflects the importance of naval U.S. naval officer and historian Alfred Thayer Mahan at the time. [Mahan] Plan Orange was U.S. Navy's strategy of how to wage a war with Japan. Both Katai Kessen and Plan Orange were based on the assumption that Japan would quickly seize the Philippine Islands and neutralise the small U.S. Asiatic Fleet. And thus the decisive battle would occur when America's primary striking force (the Pacific Fleet) would sail West and engage the Imperial Fleet just as the Russian Fleet had sailed east. There were differences as to just where this engagement would take place (Japan's mandate territories, the Philippines, or the Home Islands), but it was envisioned by both the Americans and Japanese that it would be in the western Pacific. The planning in the inter-War era did not take in account the vital impotance of both air power and the submarine. Both navies were thinking primarily of battleships. Which is why the Japanese constructed two super battleships (Yamato amd Musachi) and planned a third. Unfortunately for the Japanese, they were so sucessful at Pearl Harbor that the U.S. Pacific Fleet no longer had operational battleships (December 1941). Thus the Pacufic Fleet did not have thevships needed to execute Plan Orange. Admiral Nimitz had to devise a new strategy and the tactics for the ships that were left -- most importantly the carriers. Even before Pearl Harbor the U.S. Navy had begun to revise its war plans--the new Rainbow Plans. [Spector, Eagle ..., p. 59.] The U.S. Navy had revised the assumptions and plans for Rainbow 5 in the Plan Dog memo, which concluded that the United States would adhere to a Europe-first strategy in World War II. The Japanese did not revise their Katai Kessen doctrine even after Pearl Harbor, but by the time that the United States had built up its fleet, the Imperial Fleet had been so attritted that it had no realistic possibility of winning a major fleet action. The United Srates also lost vessels, but had the industrial capacity to build enormous numbers of new vessels. The Japanese did not. The Japanese Kntai Kessen doctrine was flawed because it did not take into account the enormous industrial capacity of the United States as well as the unlikely prospect that America, like the Russians in 1905, would be willing to make peace after losing a major naval battle. Pearl Harbor had just thebopposite of the impact intended. The American people who had wanted to avoid war wwere now united with a desire to wage war.

Pearl Harbor (December 1941)

The Japanese militarists having successfully taken on China (1894-95) and Russia (1904-05) and participating in World War I believed that in possession of a powerful fleet they could now enter World War II to complete their onquest of China and expand their empire with the Southern Resource Zone. They thought that the rich, comfort loving Americans, distracted by the Germans in Europe would not have the will or capability of fighting a war in the Pacific. It was thus the stunning surprise Japanese carrier attack on Pearl Harbor that finally propelled America into World War II. On a bright Sunday morning, the six front-line carriers of the Imperial Navy launched 360 modern aircraft at Pearl Harbor, the base of the U.S. Pacific Fleet. Sleek Japanese carrier aircraft with a destinctive red circle thundered out of the sky just as the American sailors were waking up on a sleepy Sunday morning. They not only America, but the world for ever. While Pearl Harbor was a stunning tactical victory, it was a strategic blunder of incaluable proportions. It was a stunningly successful military success, brilliantly executed by the Japanese. Several hundred aircraft, most of Pearl's air defenses, were destroyed. Most on th ground. Eight battleships, the heart of the American Pacific fleet, were sunk in additiin to three cruisrs and three destroyers. But by the slender thread of chance, the three American carriers, Yamanoto's principal objective, were not at Pearl. The Pearl Harbor attack was perhaps the greatest strtegic blunder in the history of warfare. The Japanese attack on the Pacific fleet instantly changed a diverse and quareling nation, strongly pacifistic into a single, united people with a burning desire to wage war and the vast industrial capacity with which to wage war with unprecedented intensity. The isolationism that President Roosevelt had struggled against for over 7 years instantly evaporated when the first Japanese bomb fell on Pearl Harbor. Even Lindburg asked for a commision to fight for the United States. America was finally at war.

American Carriers

The Japanese led by Admiral Yamaoto were the first to realize the full potential of naval aviation. They demonstrated this at Peal Harbor and their sweep across the Pacific in 1942. Yamamoto was correct in his assessment of the importance of the carrier. He also warned the Imperial Givernment that he could guarantee naval dominance only for 6 months. Japnese leaders had no concept of how quickly America could build new carries. In the end, the Pacific War was won by the carriers, but it was the American carriers. The primary target of the Japanese at Part Harbor were the three carriers of the Pacific fleet. By mere chance, none were at Pearl. Admiral Nimitz who after the strile was ordered to Pearl was given command of the Fleet. He had to develop a strategy to hold off the Japanese with those three carriers while America built a powerful new fleet. The United States began an emense effort to build a vast naval armada. Priority was given to 40 new carriers-many of which were the Essex class fast carriers. These enorous fighting ships were over 800 feet long and totaled 27,000 tons. These carriers, however, would not begin to arrive until 1943.

Japanese Offensive (December 1941-May 1942)

The Japanese with the U.S. fleet except for its carriers imobilized was able to launch a seies of offensives of breath taking proportions. American Pacific outposts at Guam and Wake were taken. Hong Kong fell with little resistance. Major offensives were launched in Malaysia and the Philippines. The fall of Singapore opened a drive into the Dutch East Indies and Burma. The Japanese took bith Sinaport abd Burma with relativky small forces. The Ditch and British were able to offer little resistance in Borneo and the Dutch East Indies. And finally they seized Rabaul (February 1942) and began building a major base and moving down the Solomons chain. Next they began prearing for the conquest of Australia by seizing Papua New Guinea. President MacArthur eclled General MacArthur from Corregidor and put him in charge of stopping the Japanese advance and the defense of Australia. The U.S. carriers prevented the seaborn in invasion of Papua in the Coral Sea (May 1942). Next the Marines on Midway braced for a Japanese assault and another in an unbroken series of Japanese victories. Instead American carriers theJapanese naval dominanceat at Midway (June 1942). This ended the easy Japanese victories. The Japanese invasion of Papua New Guinea began at Buna (July 1942). The first Japanese offensive to be defeated occured at Milne Bay in easter Papua where Australian infantry turned back a Japanese landing force for the first time (August-September 1942). It was a minor defeat for an enemy that un 6 months of frentic activity had carved out an enormous empire rich in the raw materials that resource-poor Japan so coveted.

Nature of the War

Most accounts of World War II find that the Pacific War was fouught more savagely than the European War, especially the fighting between the Germans and Western Allies. The differences can be exagerated. Tere were German attrcities in the West (Oradour-surGlane and Malmedy). Both the Germans and Allies carried out air raids on cvilian populations. There are, however, reasons to conclude that the fighting in the pacific Gheater reached a level of savergy not normally experienced in the Western Front of the European War. A range of explanations have been offered to explain the savagery of the conflict. Race certainly was a factor. The overwealmin factor, however, appears to be the Japanese martial code (Bushido) and the assumtion as in the case of the NAZIs that the War was won and Japan would never have to answer for the attrocities committed. In fct Japan has a nation has never come to terms with the attricities committed by the Imperial army in its name.

Doolittle Raid (April 1942)

The news from the Pacific was an unrelenting series of disasters. America needed a victory. The only intact offensive force in the Pacific was Americais carriers. Army Air Corps pilot with B-25s trained for carrier take offs. The B-25 was a medium bomber never intended for carrier use. Carrier commander Afm. "Bull" Halsey led a taskforce made up of Hornet and Enterprise. It was a risky operation as it committed half of the Pacific fleet's carrier force to a very dangerous operation. The B-25s took off from Hornet. It was the first blow to the Japanese home islands. The raid was led by Lt. Col. Jimmy Doolittle. The physical damage was inconsequential, but the psychological impact was immense. Most of the Amrican aviators crash landed in China and were helped to reach saftey by Chinese Nationalist guerillas. The Japanese reprisals were savage. A estimated 0.5-0.7 million Chinese civilians were murdered. The Japanese Navy was so embarassed that they rushed forward Admiral Yamaoto's plans to bring the desimated American Pacific Fleet to battle at Midway Island.


Allied intelligence in breaking the Japanese codes had a substantial impact on the Pacific War. This began with breaking the diplomatic purple code (1940). The prelimninary cracking of the Imperial Navy JN-25 code provide huge advantages at the Coral Sea (May 1942) and Midway (June 1942). As the initaitive shifted to the Americans, learning of Japanese intentions became less important. The code breakers did develop information that lead to an air strike which succeeded in killing Admiral Yamamoto (1943). And the Japanese Army codes were finally ctacked (1943). Cracking the Maru code provide American submarinerts a huge advantage. And the Pacifi Fleet had a huge advantage as they unleased the massive fleet of new vesselks in the Central Pacific (1944). The Americans never launched a major military deception campaign in the Pacific, in sharp contrast to the operations in Europe. One historian explains that the American assessment. The Americans believed that the Japanese Empire was "... too incompetent to understand what was being told them, and stood to low in the estimation of the decessionmakers for it to have done much good if they had." [Holt] The Americans did carryout one important deception effort--Operation Bluebird. This was designed to convince the Japanese that southern China and Formosa (Taiwan) were to be invaded rather than Okinawa.

Asian Nationalism

The Japanese in only a few stunning months after Pearl Harbor carved out a huge empire in the Pacufic and Southeast Asia. And it looked for a time that it might not only be a permanent situation, but perhaps be expanded to include Australia and India. In fact, the Japanest conquests lasted only 2-3 years. While the Japanese East Asia Co-Prosperity Sphere lasted only a few years, the impact for Asia was nothing short of monentous. The Japanese conquests has a stunning impct on Asian nationalism. Asia at the time of World War II was largely colonized or strongly influenced by European countries (Britain, France, the etherlands, and Portugal). Nationalist movements within the European empires were, except for India, weak anf poorly organized. There were no Europeam plans to grant independence. Only in the Phillipines was the United States moving toward independence. Britain was moving Ceylon and India toward domestic self rule, but not indepencence. Thus the Japanese conquests were seen in Asia in a very different light than the NAZI conquests in Europe. It also explains why resistance movements (except in Indochina and the Philippines) were weak and of little impact on the War. And the Japanese were able to orgnize local military formations (Burma, India, and Indonesia) to fight the Allies. The outcome was a notable impetus to nationalist movements throughout Asia. And within a few years after the War, the European colonial powers had granted independence to their former colonies.

Coral Sea (May 3-8, 1942)

The first importantAllied effort to stop the Japanse sweep through the Pacific occurred in the Coral Sea. The Japanse vplanned to seize Port Moreseby, completing their conquest of New Guinea. Port Moresby would have also posed a threat to Australia itself. A Japanese naval task force en route to seize Port Moresby was intercepted by an American carrier force, alerted by code breakers. It was the first carrirer to carrier engagement in history. The Japanese succeeded in sinking Lexington and heavily damaging Yorktown. The Japanese lost a light carrier and another carrier was heavily damaged. Despite the American losses, theJapanese invasion force turned back, the first major Japanese reversal of the War.

Midway (June 1942)

Admiral Yamamoto was convinced that the remaining American carriers could be brought to battle and destroyed at Midway. The Japanese plans were based on achieving an element of curprise and on the fact that two American carriers had been destoyed in the Coral Sea, in fact the Yorktown, although heavily damaged had not been sunk. American code breakers had alerted the Ameicans to the Japanese plans. Admiral Nimitz positioned Enterprise and Hornet, along with the hastily patched up Yorktown northwest of Midway to ambush he Japanese. The American carrier victory at Midway dealt a crippling blow to the Imperial Navy. The Americans sank four first-line Japnese carriers, killing most of the well-trained crews. While the Imperial Navy still held an advantage, it was no longer an overwealming one. Meanwhile American shipyards were turning out the new Essex clss carriers that would engage the weakened Imperial Navy in 1943.


While often not touched upon in military histories, a major factor in war is often food, and this was the case of the Pacific War. There were several factors at play concerning food. Most concern the Japanese and the people they occupied. First, Japan was not self-sufficent in food production and was depedent on imports to feed its people. Acquiring resource tich areas, including food producing areas was one reason Japan went to war. Second, early Japanese victories were based on seizing the supplies of the Allied armies they faced. This ended after the early victories against unprepared forces. And the result would be the starvation of Japanese forces beginning on New Guinea and Guadalcanal. Third, Japan was able to seize a vast empire, but did not have a merchant marine capable of supplying island garrisons or delivering resources including food to the Home Islands. Third, Japanese occupation policy was that every area should become self-sufficient in food. This created terrible conditions in the areas that were dependent on imports before the War. This included areas both within and outside Japanese controllded areas. Fourth, brutal Japanese occupation policies reduced harvests through out the Japanese controlled areas. Fifth, Japanese authorities turned a blind eye to the famines they caused. Sixth, most of the Pacific islands seized by Japan were self sufficent in food. They mostly operated on a primitive agricultural subsistance farming, producing just enough to feed the small island population. it was not adequate to feed a large Japanese garrison. Seventh, the Japanse Army High Command ordered Japanese garrisons throughout the Souyh Pacific, knowing that this was impossibe. Thus at the end of the War these garrisons were sarving. Eighth, as the U.S. Navy estblished control of the sea lanes to Japan, food imports were cut off. At first this meant sharp cuts in food rations, but the Japanese population on the Home Islands by the end of the War had begun to sarve. There were two important factors affecting the war in Asia. The factors concerning the Japanese in the Pacific also affected the war in Asia. First, the Japanese seizure of large areas of agricultural land in China created a food crisis for the Nationlists. At first they managed the situation fairly well. But by 1942 a very serious food shortage began to develop leading to famine cndiins in many areas. Second, the British after the Japanese seized Burma, failed to respond to the food shortage in Bengal. There were some matters affecting the Allies as well. First, Australia agreed to feed the American military stationing there to free up ocean transport for arms. Second, the Polynesian peoplewere ermanently affected by the foods intriduced by the Americans. Third, after the War, America saved the Japanese people from starving. As a result the famine deaths that the Japanese imposed on others never materialized in Japan itself.

South Pacific

The fighting in the South Pacific began after the American Naval victory at Midway. It meant that America could deploy and supply supply infantry forces on Pacific islands to stop and then push back the Japanese. The 1st Marine Division began the campaign on Guadalcanal. Army divisions would join the Marines. The close-quaters fighting in the South Pacific after Guadalcanal is one of the most neglected campaign of the Pacific War. The battles for Buna, Shaggy Ridge, and the Duriniumor River were as hard fought as many better known Pacific battlefields. Other hazzards included the Japanese sunmarines operating around New Georgia, as well as the Zeros protecting Rabaul and Wewak. [Rems] The intense fighting on Guadalcanal was accompanied with naval and air battles and at first against numerically superior, but badly led Japanese ground forces. The rest of the South Pacific campaign were different. The Japanese withdrew their fleet and new Ameican aircraft won aerial dominance as well. The various island campaigns were fought by Allied forces which not only outnumbered the Japanese, but were better equipped and supplied. While Japanese commanders on Guadalcanal showed astonishing incompetence. Their defensively tactics on the other islands was more competently conducted. Even though casualties because of their fight to the dath ethnic were much heavier than thise suffered by the Allied assault forces. Normally attacking forces suffer more casulties then fighting behind prepared defenses. The Australians participated in the fighting, especially on New Guinea, but America would be largely on its own when the fighting moved morth to the Central Pacific.

Burma (1943-45)

Once reaching India, the British and American commanders began to assess just what had happened and to plan how to not only defend India, but to retake Burma. For the Allies, the China, Burma, India Theater (CBI) was the most remote and lowest priority. The focus from the begonninwas on defeating NAZI Germany and even in the campaign against the Japapanese the CBI was of low priority. Even so, the far greater resorces of the Allies meant that more resources were available to the Allied forces than to the Japanese who were hard pressed to move men and equipment forward to the front. The major British interest was taking bavk their colony. The Americans who attached an importantce to the Chinese Nationalists with the British did not share were intent on reopning the Burma Road to Chunking China. The British planed a series of drives into Burma using mostly Indian units. They believed as a result of their experience in Burma that their own units needed training in jungle fighting. The 14th Indian Division attacked along the southern coast (January 1943), but failed to disloge heavily entrenced Japanese troops at Akyab. Stilwell's CAI was among the most effective in the Nationalist Army. While Chaing's poorly led and supplied Army in China itself declined to attack the Japanese, the CAI was both well led and well supplied. They proved themselves a competent force. It was composed of units left in Burma after the Japanese cut the Burma Road. Stillwell was an irascable, but effective commander. He spoke Chinese and earned the resprct of his Chinese soldiers. Stilwell trained the CAI along American lines. Officers were expected to train as well as men and he emphasized discipline. He also ma\de sure that commanders did not engage in corupt practices. Thus the men were well equipped and fed. The offucers as well as the men were Chinese, unlike the British Indian Army. Given the effectiveness of the units, conflict developed betweem Chaing and Stillwell. Field Marshal Sir Archibald Wavell decided tht the British troops needed to learn to fight with the Japanese in the jungel. He gave an eccentric British officer, Orde Wingate, the opportunity to carry out a jungle warfare campaign behind Japanese lines in Burma, The force became known as the Chindits, these were the name of the stone tigers that guarded temples in Burma. The Chindits adopted classic guerrilla tactics. They attacked Japanese forces where they were unprepared and did not expect an attack. Along with the British were the Gurkhas, expert at hand to hand combat. The Chindits used deep-penetration tactic. They operated in small groups and were supplied by air. The Americans formed a comparable force. The Chindit operations seemed to have convinced the Japanese that remaining static in Burma made it vulnerable . They decided on an offensive which aimed to attack Imphal, a strategic position where the British were building up their supplies ifor the planned drive into Burma. The fighting around Imphal was some of the most vicious of the War, Although cut off, the British refused to surrender, In the end the attacking Japanese force was decimimated. This was followed by the invasion of Burma. The British.Indian Army attacked in the south andthe Ameican/Cinese Army in the north, This eventually the Americans managed to build the Ledo Road which reached the nothern part of the Burmaoad and reopeed overland supply deliveries to China. The British after hard fighting reached Mandalay.

The American Submarine Commerce Campaign

Japan has aknost no natural resiyrces beyond its hard working, industrious population. Yet to wage warit needed raw materil in prodigious quantities, nit only strategic materilals (oil, rubber, and metals). nut also rice and other food as Japam is not self sufficient in food productiin. Japan ent to war to sequre the Sourgern Resourse Zone (Southeast Asia) which had the resiurces Japan lacked. But to be of any use to Jaoan, these resoitces had to be transported back to the Home Islands and the country's war industries. But Jaoan had a nerchabtnarine (Maru fkeet) that was basically adequate in war time and war requires even nore trasport caoabilities. The largely unescorted matus constituted a tempting target, jyst as the Geramns hadratgeted the Britishnmnerchant shios in the Atkantic. As a result, a day after Pearl Harbor, Washington ordered the Pacific Fleet to wagevunrestricted subnarune warfare agianst Japan. The problem with this, is that Amnerican submarine crews ommanders were not trained for this, they were not selkected for their warriit sooirit (lkike Geran anbd Jaoanese commanders, their boats had limited range, they did not have radsr to help find the marus in the vast Pacifi, the commabders didnot have the warrior vsoirit of Japanese and German commanders abd to make matters witrsem their roroedoes did not work. The Japanes aviatots whob attacked Pearl Harbir had such a low regard for submarinesm that the subs and their vfacilities were left untouched. Yet the U,S. Navy would master allm of these problens and turn the submarine force into the most effective weapn in the Amnerucan naval arsebal. By the end if the War they destouyed the maru flret and compleketyly vut Japan off from the resiyrces it had cionquered in Siutheasdt Asia lkeacing Japamnese factities ideked and its oeople near statvation. m.

Central Pacific

Japanese Army planners estimated that the United States would not be able to amass the forces for an offensive until mid-1943. Many Japanese were convinced that America would not have the stomache for fight even then. The Japanese war plan had been premised on a German victory over the Soviet Union which would have forced the United States to use most of its limited military strength in Europe. This of course not only did not occur, but America was able to generate military power more quickly and in greater strength than Japanese planners had antivipated. The fact that a cross-channel invasion was put off until 1944 meant that considerable forces could be directed tob the Pacific. Japan was shocked with the American invasion of Guadacanal and naval forces commited to the Solomins campaign. Here the Imperial Navy did not inform the Army of the full extent of the Midwat debcle. The Imperial Army and Navy was still attempting to stop the American advances in the South Pacific when Admiral Nimitz strengthen by the new Essex Carriers and Hell Cat fighters opened a new front in the Pcific War--the Central Pacific. MacArthur had oposed this being concerned about diversion of resources. In fact, the Central Pacific campaign aided his operations. From this point of theWar, the Japanese were never sure where the Americans woukd strike next. Thus they were never sure where to deploy their limited resources. The Central Pacific campign brought 20th century war to thectranquil island of the South Pacific. Americans had never heard of most of these islands. And the local people were unaware of the masdive forces being mobilized in far away Japan and America. The Imperial Fleet was withdrawn o recover from losses in the Sollomons. They hoped that a well-armed and entrenched island garrison could repell an mphibious landing. The Marines proved at Tarawa that they could not without naval support. The Marines paid a terrible price, but learned from the experiences. Losses at Kwajelin were a fraction of thoise at Tarawa. Only when the U.S. attacked the Mrianas did the Imperial Fleet intervene. The Marianas brought the Home Islands into the range of the new B-29 Superfots. The Imperial fleet intervened, but after the Marianas Turkey Shoot, the rest if the Imperial fleet withdrew. On Saipan the Americans encountered the first Japanese civilians. The Japanese finally decided to throw all of their remaining naval strength to defending the Phillipines, leading to the greast naval battle in history--the Battle of Leyte Gulf. The American victory at Leyte, meant thst the liberation of the Philippines could proceed, a long s nd bloody fight.

Pacific Strategy Conference (July 1944)

The two American offensives in the Pacific came to a conclusion at the same time. The U.S. Army under Douglas MacArthur in the South Pacific had neutrilized Rabaul and defeated or bypassed Japanese forces in the Solomons and northeastern New Guinea. At the same time, the U.S. Navy under Admiral Chester Nimitz after driving through the Central Pacific (the Giberts and Marshalls) and finally seieed the Marianas after the great naval victory in the Philippines Sea. But this brought to the fore the still unanwered question of 'where next?' There were two targets on the table. MacArthur was adament about the answer--the Philippines. Since departing Corrigedor he had repeated his goal, 'I shall return.' His argument was largely political and moral--we owed it to the Filipino people as the Philippines at the time was American territory. Admiral Earnest King believed that Formosa (Taiwan) made more strategic sense, largely because it would more more effectively interdict the delivery of raw materials from the Southern Resourse Zone to the Home Islands. A difference of such magnitude between such senior American commanders could only be resolved by President Roosevelt. The President summoned his commanders at Pearl Harbor, Hawaii to settle the issue of the direction of the advance on Japan (July 26-27). MacArthur made his and the Army's case. Nimitz made the case for the Navy. The choice would be the Philippines leading to the greatest naval battle in world history--the Battle of Leyte Gulf.

Liberating the Philippines (October 1944)

The Philippino people suffered greviously under Japanese occupation. This helped fuel an effective Resistance campaigns carried out by guerillas which had achieved control of substantial areas. The Japanese, gowever, controlled the population centers, especially on Leyte and Luzon. The Navy preferred targetting Formosa (Taiwan), but MacArthur eventually prevailed with his insistence that America must retun to the Philippines. He considered his vow to return a pledge to the Philippinp people that had to be honored. Some how his vow, "I shall return." seems less appropriate than "We shall return", but it was pure MacArthur and he convinced President Roosevelt. Reports from resistance fighters and American pilots revealed that the Japanese were not heavily defending large areas of the Islands. The invasion of Mindanao was considered unecessary and the decession was made to strike first further north at Leyte. It was in this engagement that the Kamakazis first appeared, although still in relatively small numbers. MacArthur President Sergio Osmeña waded ashore with the invasion force at Leyte Gulf (October 20, 1944). The American Army forces advanced steadily. The Japanese resisted, but could not match American fire power. The most serious Japanese resistence occurred at sea. The resulting naval engaement following on Battle of the Philippines Sea is commonly referred to as the Battle of Leyte Gulf. It was the largest sea battle ever fought and resulted in the destruction of the Japanese fleet as an effective fighting force. This opened the way for the land campaign. Further landings occurred at Ormoc (December 7, 1944).

The Home Islands

Japan began its aggression by invading Chinese Manchuria (1931). Here snd fir 14 years the Japanese inades other counttids snd territories. And even fter the y were stopped at Guadakcanal, they fought the war locatiins fsr away from the Japanese Home Islands. The little white boxes came home to Japanese mothers and rationing brcame more severe, but the actual fighting was still in distant lands. This changed dramtically in 1945. It should not have been a surprise to any Japanese people reading a map. Nut one catasteophe after another began to unfold. The American took Iwo Jima (February 1945). Iwo was the first Japanese territiory to fall to the Americans. This was followed by the first really destructive air raids (March 1945). In the ensuing months, the United States would burn the heart out of industrial Japan. Than the Americans landed on Okinawa, another actual Japanese territory. The Generals assured the Emperor that this would be the decusibe battle and they woiuld be defeated. They had mdde thee same preduction about other major battles. After Olinaw fell--the Emperor wuth Tokyo burning befiore his eyes lost all confidence in the miliitary. After Okinawa fell, it was clear that the Americans were preoaring to invade the Home Islands and they realised that the blow would begin in southern Kyhshu which was un range of newly won air bases in Okinawa. The Japanese began a massive builup of man and material in Khyshu. Units were drawn down from China and Manchuria to prepare for the invasion. Not only were military resources deplouyed, but the Japnrse organized civilians, including children, to stop the Americans. All of the Japanese islands are mountaneous, including Khhshu. This provided like Okinawa, enumeral defensive positions to klll Americans. This was a strategy the Japanese adopted beginning with Trawa in the Gilberts. The Japnese believed that if the killed enough Americans that the United States would tire of the War and make peace. Unfortunately for the Japanese it failed on Pacific island after another. It not only filed, but convinced the Ameticans that the atomic bomb had to be used to avoid the terrible bloodletting that would result from an invasion. The Anmeicans might have used the bomb anyway, but the terrible losses on Iwo and Okinawa made the use of the bomb inevitanle.

Atomic Bomb (August 1945)

The American Manhattan Program was initiated by President Roosevelt when work done by German physicists led to concern that th NAZIs might build an atomic bomb. Jewish and oher refugees fleeing the NAZIs made a major contribution to the success of the Manhattan Program. The first bomb was successflly tested at Alamagordo, New Mexico on July ??, 1945. The Allies met in a Berlin suburb after the NAZI surrender to make dcisions about the occupation of Germany and defeating Japan. The Allied powers 2 weeks after the bomb was tested demanded on July 27, 1945 that Japan surrender unconditionally, or warned of "prompt or utter destruction". This became known as the Potsdam Declaration. The Japnese military was prepared to fight on rather than surender. The Japanese Government responded to the Potsdam Declaration with "utter contemp". The Japanese military continued feverish pland to repel the Ameican invasion of the Home Islands. Many Whermacht generals at the end of the War were anxious to surrnder to the Amreicans. One German General commanding forces as part of Venk's 9th Army west of Berlin after the War said, "We wondered why the Americans didn't come." This was not the attitude of the Japanese military. I know of know memoir written by an important Japanese military officer expresing similar sentiments. Truman was not anxious to use the atomic bomb. He was anxious to end the War and limit Ameican casulties. For Truman, the American casualties on Okinawa and the Japanese response to the Potsdam Declaration made up his mind. There have been many books and aticles published in both Japan and America about the atomic bomb. Japanese scholars have reserched the decission making process that led to the dropping of the atomics bomb. Almost always the focus is on Truman and American military leasers. Rarely do Japanese authors address the role of Japanese political and military leaders. The United States dropped two atomic bombs on Hiroshima and Nagasaki on August 6 and 9, and the Soviet Union entered the war against Japan on August 8.

Soviet Declaration of War (August 1945)

The American Hiroshima attack caused Stalin to order the immediate declaration of war on Japan and invasion of Manchuria least Japan surrender before the Soviets attacked. The Soviet Union, 2 days after the first atomic bomb was dropped, entered the war against Japan (August 8). Stalin as promissed at Yalta and Potsdam declared war on Japan. At the time the Japanese were attempting to use the Soviets to mediate an end to the War. He moved the date up after the Hiroshima bombing because he wanted to be in the War before Japan surrendered. Soviet plans included the invasion of Manchukuo (Manchuria), Mengjiang, Korea, the southern portion of Sakhalin, the Kuril Islands, and Hokkaido. All these operations except the invasion of Hokkaido were carried out. The Soviets struck in Manchuria and routed the Japanese forces there. The offensive was in sharp contrast to the campaigns the Americans conducted in the Pacific. The Soviets after declaring war immediately launched a massive invasion--the largest ground operation of the Pacific War. The Red Army rapidly swept over Manchuria. Japanese resistance crumpled. The Soviet invasion is not well covered in Western histories of the War. One question that arises is why the Soviets so quickly suceeded in Manchuria while the United States struggled in Okinawa. I think this is primarily because Okinawa was a small island where the Japanese could concentrate their forces in mountainous terraine. Manchuria was a huge area, much of it a flat plane, idea for tank warfare. The Japanese could not defend it like they were able to do on Okinawa. Perhaps readers more familiar with the Soviet invasion will be able to tell us more. Soviet plans included the invasion of Manchukuo (Manchuria), Mengjiang, Korea, the southern portion of Sakhalin, the Kuril Islands, and Hokkaido. All these operations except the invasion of Hokkaido were carried out. The Soviet invasion was code named Operation August Storm. The massive Soviet invasion swept aside Japanese resistance. The Japanese were surprised and destroyed any illusions among the military that Japan's still substantial army had the ability to resist Allied armies. Some authors believe that the success of the Soviets in Manchuria and the inability of the Japanese army to resist them, had more of an impact on the Japanese military than the two American atomic bombs. One factor that we are not yet sure about is why Japanese resistance in Manchuria colapsed so quickly and why the Japanese military commanders were willing to surrender to the Soviets, but unwilling to surrender to the Americans in Okinawa or the Philippines. The Japanese that surrendered to the Soviets spent years in the Gullag. They were used for years in construction projects in Siberia and Central Asia. [Solzhenitsyn, p. 84.] Only about half survived and ever returned to Japan.

Soviet Invasion of the Kuril Islands (August 1945)

Stalin wanted to share in the occupation of Japan of Japan in the same way that the occupation of Germany was unfolding. While he had assembeled a massive force in the Far East and used it to invade Mnchuria and Korea (August 8). Invading Japan, however, was a very different matter. The Soviets did not have the sea-lift capability of getting part of its Far East forces to the Japanese Home Islands. The Soviet Manchurian Strategic Offensive Operation included plans to invase Hokaido, the norther Japanse Home Island. It soon became apparent that the limited Soviet Sea-Lift capability made this impossible. Instead they conducted a an opeation to seize the much smaller Kuril Islands extenting from Japan's Hokaido in a northerly arc to the Soviet Kamchatka Peninsula. The only battle of the Soviet campaign was the Battle of Shumshu. This was to be the beginning of a Soviet effort to seize the Kuril Islands and hopefully northern Japan. It proved to be the only major battle of the Soviet Kuril campaign and one of the last battles of the War. The United Statrs as the war wound down in Europe pressed Stalin to enter the Pacific War agint Japan. Stalin wanted to do just that, but his desire to do so. He agreed to do so only after the Grmans surrendered abd then with a-month lag time to transer forces east. He also demanded Lend Lease aid for his Pacific forces. The United States complied, including transfering a dozen types of ships and aircraft to the Soviets. The United States secretly transferred 149 ships and aircraft (Spring-Summer 1945). They included vessels needed for amphibious operations. Most were escort vessels, landing craft, and minesweepers (Spring-Summer 1945). The trabsfer occurred at Cold Bay in Alaska and was named in Project Hula. [Russel, p. 8.] Some historians argue that President Truman because of problems dealing with the Soviets in post-War Germany was not interested in a joint American-Soviet occipation of Japan. [Hasegawa] The Soviets encountered considerable resitance, largely because of their inability to move a subtantial force to Shumshu. As a result there was no fighting further south. Victory came only when the Japanese Goverment convined their forces on Shumshu to cease reistnce (August 23). The Soviets encounterd no further resistance in its seizure of the Kuril Islands (completed by September 1). The Soiviets given the levl of resistnce on Shumshu and their limited sea-lift capoability abndoned plans to invade Hokaido.

Surrender (August 14-September 2, 1945)

Most Americans believe that the Japanese surrendered because of the American development and use of the atmonic bomb. The bomb was certainly a factor, but not the only factor. The decesion to surender is far more complex and impossible to know with any surity. The American Pacific Island invasions, naval power, and in particular the Soviet declareation of war and starteling sucess of the their invasion of Manchuria all played major roles. The success of the Soviet Army convinced even Imperial Army officers and the Ministry of war that defeat was inevitable. Emperor Hirohito on August 14 decided to surrender unconditionally. Even after the atomic bombs and the debacle in Manchuria, there were hardliners that were opposed to surrender. A group calling themselves the Young Tigers seized the Imperial Palace grounds and tried to prevent the Emperor's surrender broadcast. The attempted coup almost succeded. On what has become called "Japan's Longest Day" the attempted coup, bombing raid blackout, intrigues, killings, and sepukus determined fate of millions of Japanese people. It iwas a complicated series of events involving both great heroism and treason by officers convinced that they were behaving honorably. The Commander of the Eastern Army, however, remained loyal to the Emperor, dooming the coup. [PWRS] The formal surrender was held underneath the guns of the battleship USS Missouri in Tokyo Bay (September 3). Not knowing just what the Japanese were planning, the American carriers were standing at sea off Japan.

Occupation and Aftermath

American troops landed in Japan immediately after the Imperial Government surrendered on September 3. The American occupation was completely unlike the Japanese occupation of the countries that it had conquered. Most Japanese were stunded by the final year of the War and the massdive destruction. There was also widespread hunger. Many Japanese had been led to expect a brutal American occupation. The United States oversaw an occupation with fundamentally changed the nature of Japanese society, rooting out Japanese militarism and fomenting the development of democratic political regimes and social structures. Women were enfranchized and labor unions allowed to organize.


The situation in Asia and the Pacific was different after the Japanese surrender than after theGerman surrender in Europe. There was not much left of the NAZI empire (only Norway, Denmark, parts of Bohemia, and pats of Austria). Large areas of the Pacific and Southeast Asia, however, were still in Japanese hands and occupied military forces quite capable and willing to fight. The Japanese still occuppied the Dutch West Indies, parts of Burma, Malaya, Singapore, and Indochina as well as Taiwan and large areas of mainland China. Moving into these areas to acceot the surrender of the Japanese and restablish civil order wee complicated by the large areas involved, the distances, and limitations of transport. The Dutch and Pacific had no substantial forces in place to do this. The problems meant that it would take some time for the Allies to move forces into these areas. A complicating factor was there were now local military forces, both resistance forces and national forces the Japanese had armed to assist them. Asia was different than Europe. Most of the territory conquered by the Japanese were colonies. Thus the local population was generally not overjoyed with the prospect of the old colonial powers (British, Dutch, abnd French) coming back. Only in the Philippines were the Allies (Americans) generally regarded as liberators, and even in the Philippines the resistance movement included a Communist force that was anti-American. The Allies thus in some areas used Japanese troops to keep order until they could reoccupy the areas that the Japanese had conquerred. And in all of the places except Burma where the British pulled out, colonial wars resulted.

Modern Asia

The Pacific War was in many regards the birth of modern Asia. One work describes the War as the beginning of the evolution of the Asian colonies to modern independent countries. [Bayly and Harper] Almost all the Asian countries before the War were either European colonies. Much of China was occupied by Japan and its major seaports under the control of European countries. At the time war broke out in Europe, the only country scheduled for independence was the American Commonwealth of the Philippine Islands. German victories in Europe (1940) undercut the Dutch and French colonies. With Pearl Harbor the Japanese lauhed an offensive that brought them to the borders of India. While the Japanese were defeated and the colonial regimes restored, with only a few years, virtually every colony in Asia achieved its independence. Much of it was accomplished by negotiations, most notably the independence of India and Pakistan. In other countries there were wars for independence, most notably the French struggle in Indichina/Vietnam. The War had both stimulate nationalist feelings as well as exposed the limitations of European military power.
