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 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 knowkedge of Anmerica were convinced that the United states would not have tge stomache to wage the military campaih=gn to oust them. The Japanese decesion isall 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 psrt, however, Japanse Army commanders were unimaginative. 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 effectib=ve fighter in the Pacific, but the Army's equioment was of generally poor quality. Even worse by launcjing the Pacific War, the Army which was concenttated in Chinma, would have not wat=y of deployinbg its trength effectively to impede the U.S. Navy's advance across the Pacific toward the Home Islands.
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.
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.
After Germany's defeat of France (June 1940), Japan occupied French Indochina (Vietnam) in 1940. America in response to began to take economic sanctions against Japan.
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.
Hoping to avoid 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 Dutch East Indies (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.
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. 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. Also most Americans did not consider the Japanese to be capable of building hogh quality ships or planes or the Japanese to be effective fighters.
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.
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.
A Japanese carrier taskforce composed of six carriers on December 7, 1941, executed a surprise attack on the American Pacific Fleet at Pearl Harbor. It was a brilliant tactical victory for Japan, but perhaps the greatest mistake in modern military history as it brought a suddenly united America with its vast industrial capacity into the War. The Japanese launched 360 aircraft which in 2 hours struck Peal Harbor just as the American sailors were waking up on a sleepy Sunday morning. The strike sunk or heavily damaged six of the eight American battleships, thrre cruisrs, three destroyers, and most of the Army Air Corps planes on the island. America was at war.
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.
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.
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.
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.
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.
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.
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 Jaspanese 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.
New Guinea was the longest campaign of the Pacific War. The Japanese took Western News Guina and much of the northern coast without seriou opposition. The Japanese were twarted in their effort to complete the conquest of New Guinea by American carriers in the Coral Sea (May 4-8, 1942). The Japanese landed along the northern coast of New Guinea. After seizing Buna, Gona, and Sananda (July 21-29, 1942) they controlled the northern coast. As an an amphibious operation was no longer possible after the Miday losses (June). Still attmpting to take Port Moresby, the Japanese embarkened on one of the most incredible offensives of the war. They launched an attack of over 1,000 miles over the Kokoda Trail (July 30).. Major General Tomitaro Horii led a force of 8,500 men from the 144th Regiment of the South Seas Detachment. The Japanese achieved the impossible in 4 week epic trek. This meant that by the time the Japanese reached Port Moresby tey were exhausted, low on supplies and lightlyv armed. They were stopped 30 miles from Port Moresby by the well supplied. Incresiby despit the fact that the Japanese were near starvation and no expecting to dind Australian opposition, they made a fight of it. Eventually they had to fall bac (September 24). This proved to be the first land victory over the Japanese of the War. Before that the Japanese landed at Milne Bay at the eastern tip of New Guinea (August 25), but were forced to withdraw when the Australians held and thr Japanese withdrew (September 5). The Japanese Army's focus on New Guinea was one reason they did not react more immediately to the American landings on Guadacanal. After the American victory in the Solomons, MacArthur launched a series of attacks along the northern coast of New Guinea, bypassing and isolating many Japanese bases. Buna was the first New Guinea base taken (January 2, 1943).
The first America land offensive in the Pacific occurred on the virtually unknown island of Guadalcanal in the Solomons. The Japanese built aeaplane base atvTulagi. Allied coast watchers reported the Japanese were building an air strip on Guadacanal which was cinfirmed by aerial reconisabnce. From that base, the Japanese could threaten the sea lanes to Australia. A marine invasion force was rapidly assembled. It was a risky operation from the onset. Although dealt a serious blow at Midway, the Imperial Navy still was thecstringer if no longer dominantb naval force in the Pacific and outnumbered the American Pacfic fleet in virtually every class of warship--including carriers. The Japanese did not expect an American iffensuve until mid-1943. Given Japanese naval superority and air power, the Japanese should have won the battle, especially as they managed to land more men on the Island than the Americans had. An almost incredible lack of military competence on the part of the Japanese commanders led to their defeat. Incrediblt, the entire Pacific War would turn on this virtually unknown island. Americans and Japanese would fight both on the island and in a series of ferocious sea battles around the island.
Admiral Isoruku Yamamoto, commander-in-chief of the Japanese Combined Fleet, was for Americans only below Tojo znd the Emperor on the list of villans responsible for the war. Yamaoto had planned the Pearl Harbor attack. He actually had been against going to war with the United States, understanding more than most of his colleague America's vast indistrial power. Once the decesion was taken, he threw his considerable energy into planning and execuring Japan's war policy. After the First Air Fleet was devstated at Midway, however, there was little he could do to reverse America's application of its the military power generated by its industrial and technological superiority. When code breakers picked up transmissiins about a fsct-finfding gour of front-line bases, Admiral Nimitz ordered a shoot down. The chances were slim of sctully encountering his plane, but long range P-38 lightings from Guadacanal did just that. They shot down just before it landed at Kahili airfield at the southern tip of Bougainville (April 18, 1943). This of course was another clue that JN-25 had been broken, but the Japanese did not conclude that their codes had been penetrated. The Japanese cintinued to use JN-25 with only minor changes throughout the War. His death ws a shock to the Japanese people who continued to be told that their country was winning the War.
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.
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.
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.
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 Osmeņa 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 air war in the Pacific began as in the European theater with mastery of the skies by the Japanese. The Chinese air force was virtually non-existant. The Japanese conducted terror bombing raid, first on Shanghai and then on other Chinese cities. Japanese aircraft, especially the Mitusubishi Zero, were so effective that they were able to achieve air
superority during land and sea battles against Britain and the Unitd States beginning with the attack on Pear Harbor. This continued throughout much of 1942 and only did the arrival of ne American aircraft in large numbers did the Allies begin to gain the upperhand in the sky. The seizure of the Marianas and the deployment of of the new long range B-29
bombers brought the Japanese homeland within range of strategic bombardment. The initial raids wereinclonclusive. General Curtis LeMay devised a trategy of fire bombing which caused massive destruction in Japanese citis crammed with highly flameable wooden structures. When Japan refused to surender after the Yalta Conference, President Truman ordered the use of tha Atomic Bomb in August 1945. The Japanese surendered in
Virtually no one, including most Japanese, had ever heard of Iwo Jima, before the Pacific War. It was an isolated, barren unoccupied volcanic outcropping about 600 miles south of the Japanese Home Islands. As with many Pacific islands, it location suddenly made it of great strategic importance. After the United States began the strategic bombing campaign from the Marianas, it became important to obtain a forward base for the fighters covering the bombers. Iwo was ideally placed for just such an effort. It would also be useful as a safe haven for damaged bombers unable to reach their distant bases on the Marianas. The Japanese anticipated this even before the Americans seized the Marianas and began building air strips for the new B-29s. They began to heavily garrison and forify the island. Lieutenant General Tadamichi Kuribayashi was assigned to defend the island (June 1944). Kuribayashi by this point in the War was not under the illusion that he could defeat an American landing, even with a lsrge, well-armed garrison. His assignment was to kill as many Americans as possible before he and his command was defeated. Iwo Jima American planners did not appreciate the size of the garrison or the extent of Kuribayashi's preparations, largely because it was mostly done underground. Admiral Marc Mitschner commanded the naval task force. Marine General Hollmand Smith commanded the Marine landing firce. Pre-invasion shelling and carrier strikes did little damage to the Japanese defensives. Marines invaded the island believing the naval shelling had been effective and that it would be a few days of intensive fighting February 19). It took the Marines over a month to secure the island and they suffered an incredible 30 percent casualties, neaely 7,000 killed and 19,000 wounded. This was a greater toll than the D-Day landings. . Virtually all of the 22,000 man Japanese garrison refused to surrender and perished. About 200 Japanese soldiers were captured, many were too badly wounded to commit suiside. Crippled B-29s began landing on Iwo while the fighting was still going on.
The Japanese kamikaze attacks are geberally seen as crazed attacks by mindless Japnese pilots anxious to die for their Emperor. This is a misunderstanding. The Japanese by 1945 had no effective weapons to use agains the American fleet. There only hope was to exact such casulties that America would tire of the War. In this regard they were effective. The Pacific fleet did sustain serious losses at a relatively light cost on the part of the Japanese. The pilots involved were not anxious to die, but thought theu were making a contribution to the defense of their country. Peer pressure among these young men was a very powerful force. [Spector]
The invasion of Okinawa was the first American attack on Japanese territitory. Okinawa, in the Ryukyu Island chain was strategically located between Kyushu, the southernmost Japanese island and Taiwan (called Formosa by the Japanese). American strategists saw Okinawa as a necessary base from which an American invasion of the Japanese home islands could be staged. Okinawa had several air bases and the only two important harbors between Formosa and Kyushu. The American invasion was code named Operation Iceberg. The greatest naval force in histoy was assembled for the invasion. Admiral Raymond A. Spruance's 5th fleet included more than 40 aircraft carriers, 18 battleships, 200 destroyers and hundreds of support ships. Over 182,000 troops participated in the invasion. The American invasion forced was surprised when the beach landings were unopposed. Okinawa was defendened by the 32nd Japanese Army and a garrison of about 110,000 men. The Japanes had drawn back from the onvssion beaches. The Japanese strategy was to bring as many ships as possible in close to the island to support the invasion. it was then that a major Kamakazi attack was unleased on the invasion fleet. The Japanese on April 6-7 employed the first massed formations of hundreds of kamikaze aircraft. The Japanese during the Okinawan campaign flew 1,465 kamikaze flights from
Kyushu. They succeedd in sinking 30 American ships and damaged 164 others. Other ships were attacked nearer Kyushu and Formosa. The Army Air Corps had rejected a request to havily bomb these air fields as it was seen as a diversion from the strategic bombing campaign. One third of the invasion force was killed or wounded. Over half of the 16,000 Americans killed were sailors on the ships attacked by the Kamakazis. Virtually the entire Japanese garison died in the Okinawa campaign. Few Japanese soldiers surendered even after defeat was certain. Large number of civilans were also killed. The Jaoanese military reserved available food and supplies for its use and in many cases forced civilians to commit suicide. The American military saw Okinawa as a dress rehersal for an invasion of the Japanese Home Islands and anticipated even fiercer resistance. The extent of the casualties was a major factor in the American decission to use the atomic bombs.
Japan in 1945 was in a very different position than Germany. The Bulge offensive was Germany's last desperate gamble. The German armies in all sectors (except Norway) were defeted abd no longer capable of offereing effective resistance in either the wetern or eastern fronts. The generals saw no posdibility of staving off defeat and the situation became increasingly ckear as the Western llies and Soviets drove into the Reich. The situarion for the Japnese was very different. Defeat had only been experienced at sea and on Pacific islands invokving relatively small garrisons. The bulk of the Imperial Army ws still in tact in China and facing Chimese armies of limited capabiities. And even after Okinawa, the Jpanese had a very creditable military force as well as a largely hidden force of Kamikazee aircraft ready to reign hell on any invasion fleet. In addition the Government were still controlled by miklitary men concerned primarily with their honor and seeing no obligation to the civilian population. The War Cabinent even after the Nagasaki attack was was still undecided on surrender. War Minister Korechika Anami still wanted to continue the War, When told about the mushroom cloud, he replied, "Would it not be wondrous for this whole nation to be destroyed by a beautiful flower?" [Pellegrino] And this is how many Japanese military commabders thought. It seems almost incredible today, but it was all true in 1945. Many Army commanders simply saw it dishonrable with strong forces in the field to surrender. And to them honor transcended the future of their nation.
The last step in the war against Japan was the invasion of the Japanese Home Islands. American military planners forsaw 0.5 million American casulaties. This was based on the tenacious Japanese resistance in every Pacific campaign. The military fully expected the Japanese Army to resist to the death just had they had done on Okinawa. In addition, the Japanese had large numbers of aircraft which could be used in Kamakazi attacks on any invasion fleet. Many Japanese today maintain that Japan was near defeat and ready to surrender. It is cerain true that the military situation for Japan was hopeless and the population approaching starvation. This does not mean, however, that the Imperial Army was preparing to surrender. The Army had not surrendered in any other campaign where the outcome was hopeles. In addition, the Army had incouraged even forced civilians to commit suiside as on Siapan and Okinawa. Some observers are convinced that Japanese civilian casualties in any invasion of the Home Islands would have been the greatest civilian disaster of World War II. Millions of Japanese soldiers and civilians may have died if America had invaded Japan.
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.
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.
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. Not knowing just what the Japanese were planning, the American carriers were standing at sea off Japan.
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.
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.
