The Solomon Islands campaign was one of the major campaigns of the Pacific War. It was in the Solomons and the waters and around the Solomons that the Japanese offensive begun at Pearl Harbor was first stopped and then reversed. The Solomons located just east of New Guinea were virtually unknown before World War II. The Germans had briefly occupied the islands north of the Solomons during their colonial outreach and naval building time. These islands since World war I had been admistered by the British and Austrlaians. The Solomons had few resources. What they did have was a strategic location. The Japanese landed and occupied several areas in the British Solomon Islands and Bougainville, in the Territory of New Guinea (early 1942). A Japanese naval task force to take Port Moresby was turned back by American carriers in the battle of the Coral Sea fought southeast of the Solomans (May 1942). The Japanese continued, however, to occupy the Solomons and began the construction of several naval and air bases. They had three objectives. First to protect the flank of opperations in New Guinea. Second to establish a security barrier for the huge naval and air base at Rabaul on New Britain. Third to provide bases for interdicting supply lines between the United States and the principal remaining Allied outposts in Australia and New Zealand. After the devestating Japanese losses at Midway (June 1942), the Japanese Imperial Fleet no longer had the naval force to sever the sea lanes between America abd Australia. Air bases in the Solomons, however, could help with that effort. The Solomons thus became the scene of some of the most furious battles of the War. It was here that American Marines conducted the first Allied offensive in the Pacific and the Japanese Imperial Fleet and American Pacific Fleet fought a series of desperate naval battles. Unlike the subsequent naval actions in the Pacific, the Japanese Imperial Fleet still had the advantage of superial naval forces, but no longer overwealming air superiority. The Japanese at first considered the Solmons a side show to New Guinea and belatedly came to see the importance of the struggle. Despite the initial syperior firces deployed in the area, especially superior naval forces, the Japanese were unable to convert their material advantage into a victorious military campaign.
The Solomons located just east of New Guinea were virtually unknown before World War II. They are a twin chain of volcanic islands streaching 900 miles in a parallel arangement north and south. The water area between the two chains came to be called the Slot. The volcanic islands are mounatenous and heavily covered with tropical vegetation. There are also small coral atols. There are about 1,000 islands and atolls. The major islands included the British Protectorates of Guadacanal, Malaita, New Georgia, Santa Cruz Isles (group), Choiseul, Santa Isabel, San Cristobal, and Shortland. Bougainville and Buka in the north were administered by Australia as aprt of the New Guinea Mandate. The main exports were copra and timber. The Solomons had few resources. What they did have was a strategic location.
Archeologists believe that people reached the Solomon Islands (about 2000 BC. Europeans first reached the Solomons in the 16th century. The Spainard Alvaro de Mendana first mentiined the islands (1568). There was initially little interest in colonizing the islands. Britain and Germany divided the islands between them (1886). The British placed the southernn solomons under a protectorate (1893). This wasc extended to the Eastern Solomons (1898). The Germans briefly occupied New Guinea and the northern Soloons during their colonial outreach and naval building effort. The Germans transferred the northern Solomons (except Bougainville and Buka) by treaty to Britain (1900). The British and Austraklians seized the German possessions during World war I (1914-18). The islands since World war I were thus admistered by the British and Austrlaians.
The Japanese landed and occupied several areas in the British Solomon Islands and Bougainville, in the Territory of New Guinea (early 1942).
A Japanese naval task force to take Port Moresby was turned back by American carriers in the battle of the Coral Sea fought southeast of the Solomans (May 1942). The American lost the carrier Lexington while sinking only a smallJapanese carrier. The two most powerful Japanese fleet carriers Zoikaku and Suikaku, however, were put out of actionand were thus unavailable for the Midway operation. The American carriers had been deployed in the Cora Sea because code breakers on Pearl had broken the Japanese naval code. The Japanese did not pursue the question of why the American carriers suddenly appeared in the Coral Sea. Th fact that they has sunk Lexington and they thought Yorktown apparently was a factor in not throughly assessing the battle. The Japanese Army decided to take Port Moresdy in an overland offensive.
The Japanese continued, however, to occupy the Solomons and began the construction of several naval and air bases. They had three objectives. First to protect the flank of opperations in New Guinea. Second to establish a security barrier for the huge naval and air base at Rabaul on New Britain. Third to provide bases for interdicting supply lines between the United States and the principal remaining Allied outposts in Australia and New Zealand.
The Japnese were shocked when the American carriers syddently appeared unexpectedly again. The result was the loss of four of the six fleet carriers of the Imperial Fleet. This significantly altered the naval balance in the Pacific. After the devestating Japanese losses at Midway (June 1942), the Japanese Imperial Fleet no longer had the naval force to sever the sea lanes between America abd Australia. Thus the previously little-regarded Solomon Islands began to take on much greater importance. Without carriers, the Japanese decided they could projrct air power by building island air bases. Air bases in the Solomons, however, could help with that effort. The Solomons thus became the scene of some of the most furious naval and air battles of the War.
It was in the southern most island in the Solomons chain that American Marines conducted the first Allied offensive in the Pacific. Allied coast watchers reported the Japanese were building an air strip on Guadacanal. From that base, the Japanese could threaten the sea lanes to Australia. The United States to defend communication and supply lines to the South Pacific decided it was important to prevent the Japanese from completing an air base on Guadacanal. A great deal was at stake. The Allies were building up forces in Australia and clininging on to Port Moresby along the southern coast of New Guinea. The forces in Australia were to be used to take New Guinea and destroy the Japanese base at Rabaul. American Marines landed on Guadacanal (August 1942). The first America land offensive in the Pacific occurred on the virtually unknown island of Guadacanal in the Solomons. American planners had not planned for such an early offensive. The Japanese had concluded that an American offensive was several months away. 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 dominatd the Pacific and outnumbered the American Pacfic fleet in virtually every class of warship--including carriers. The Japanese were surprised. While they responded quickly, they were not at first aware of the dimensions and capabilities of the American firce.
The Japanese Imperial Fleet and American Pacific Fleet fought a series of desperate naval battles. Unlike the subsequent naval actions in the Pacific, the Japanese Imperial Fleet still had the advantage of superial naval forces. The initial important naval battles were carrier battles. It was in the Solomon Islands that the U.S. Navy surface fleet first came to grips with the Imperial Navy. The Pacific Fleet with its battleships devestated at Pearl Harbor faced a far superior naval force. The Japanese after seizing the Dutch East Indies (Indonesia) took the Solomon Islands (mid-1942). Allied inteligence detected the construction of an airbase on Guadalcanal. This was a step of considerable importance as an airbase on Guadacanal would assist the Japanese in cutting off American troops and supplies fromn reaching Australia. Unlike the Americans, Japanese construction methods were slow, giving time for the Americans to prepare its first major offensive action of the Pacific War. The First Marine Division still training in New Zealand under Alexander Van der Grip dispatched in great secrecy. They reacged Guadalcnal undected by the Japanese. The Marines took Tulagi, a small island off Guadalcanal on Augut 7. They also landed on Guadalcanal and quickly seized the unfinished Japanese airfield, naning it Henderson Field after an aviator killed during the Battle of Midway. The surprised Japanese on Guadalcanal reorganized inland and counter attacked. The Japanese sent a force of seven cruisers and one destroyer from their base ar Rabal. The route traveled was "The Slot", a slot-like channel formed by the parallel configuration of the Solomons. In a night action off Savo Island they destroyed the Allied cruisers covering the landing (August 9). The Allied landing force was forced to withdraw without unloading all of the Marines' supplies and snuck into the waters. This left the Japanese with air and naval supperority over the Marines that had landed. The Japanese came down the Slot daily to bomb and shell the Marines. Their main target was the airstrip which the Marines rushed into operation. Despite the American victory at Midway, the Japanese still had superior carrier and naval forces. The Japanese did not at first appreciate the importance of the American action. Henderson Field thus played a major role in proecting the Marines from Japanese air strikes and naval bombardment. American fighters fought off Japaneseplanses and made it impossible for the Japanse Navy to direct intense naval bombardment. American bombers launched strikes on Japanese bases in the northern Solomons. The Marines were helped by friendly Melanisian natives which the Japanese had uickly alienated when they arrived. Continuing Japanese pressure began to ground down the Marines. Nimitz transferred overall command to Admiral Bull Halsey who pledged the Navy would intensify support. This was a dangerous commitment at a time when the Japanese still had superior carrier and naval forces. The Japanese launched a major force to destroy American naval forces supporting the Marines. The Battle of Santa Cruz occured when the Japanese found Hornet which was badly damaged (October 26). Hornet was left dead in the water and had to be scuttled. Santa Cruz was a victory for the Japanese, but they did not press their victory. The Americans on Guadalcanal relieved the hard-pressed Marines with fresh Army units. The Japanese had managed to buildup a sizeable force on the island, but were unable to keep them supplied because of the American fighters on Henderson Field. Finally Guadalcanal was declared secure (February 9, 1943). The Americans had retaken the first island on the long road to Japan.
The Japanese also had superior air forces in the initial phase of the Solomons campaign, but no longer overwealming g air superiority. The Japanese at first considered the Solmons a side show to New Guinea and belatedly came to see the importance of the struggle. Despite the initial syperior firces deployed in the area, especially superior naval forces, the Japanese were unable to convert their material advantage into a victorious military campaign.
The Guadacanal landings initiated a series of combined-arms battles on and off Guadacanal and the southern Solomons. After Guadacanal was secured. The U.S. Marines and Army began moving north. There were several battles in the central and northern Solomons, on and around New Georgia. These battle took on the character of isolated land battles as at the end of the 1942 the Imperial Navy withdrew from the Solomons and ceased fleet actions to oppose the American landings.
