Pacific War
In January 1941, the Commander in Chief of the Japanese Combined Fleet, Admiral Isoruku Yamamoto began planning for a surprise attack on the US Pacific Fleet at Pearl Harbor. Yamamoto feared that he did not have the resources to win a long war against the United States. He therefore advocated a surprise attack that would destroy the US Fleet in one crushing blow.
Yamamoto's plan was eventually agreed by the Japanese Imperial Staff and the strike force under the command of Vice Admiral Chuichi Nagumo sailed from the Kurile Islands on 26th November, 1941.
Richard Sorge, a German journalist working as a Soviet agent in Tokyo, discovered details of the plan for the attack on Pearl Harbor. However, this information does not seem to have been passed onto the United States. US Army intelligence. It did intercept two cipher messages from Tokyo to Kichisaburo Normura, the Japanese Ambassador to the United States, that suggested an imminent attack, but no action was taken.
Nagumo's fleet was positioned 275 miles north of Oahu. On Sunday, 7th December, 1941, 105 high-level bombers, 135 dive-bombers and 81 fighter aircraft attacked the the US Fleet at Pearl Harbor. In their first attack the Japanese sunk the Arizona, Oklahoma, West Virginia and California. The second attack, launched 45 minutes later, hampered by smoke, created less damage.
In two hours 18 warships, 188 aircraft and 2,403 servicemen were lost in the attack. Luckily, the navy's three aircraft carriers, Enterprise, Lexington and Saratoga, were all at sea at the time. The following day, President Franklin D. Roosevelt and a united US Congress declared war on Japan.
The following day Japanese troops invaded Malaya, Thailand, Batann Island in the Philippines. In the next few weeks the also made further landings in the Philippines. Burma was invaded on 11th December and Borneo two days later. On 25th December, 1941, Hong Kong surrendered with the loss of its 12,000 garrison.
After the bombing of Pearl Harbor Admiral Chester Nimitz was was placed in charge of the Pacific Fleet. Urged on by Admiral Ernest King, Commander in Chief of the US Fleet, Nimitz sent William Halsey to attack the Marshall Islands and Frank Fletcher to raid the Gilbert Islands.
In the early months of 1942 the Japanese Army continued to make gains in the Pacific War. On 8th February, 1942, 13,000 Japanese troops landed on the northwest corner of Singapore. The next day another 17,000 arrived in the west. General Arthur Percival, the British commander of forces in Singapore, moved his soldiers to the southern tip of the island but on 15th February he admitted defeat and surrendered his 138,000 soldiers to the Japanese.
The Japanese Army also made steady progress in the Philippines and soon held the three air bases in northern Luzon. General Douglas MacArthur now ordered a general retreat to the Bataan peninsula. A series of Japanese assaults forced the US defensive lines back and on 22nd February, 1942, MacArthur was ordered to leave Bataan and go to Australia. General Jonathan Wainright remained behind with 11,000 soldiers and managed to hold out until the beginning of May.
On 9th March the Japanese gained complete control over the Dutch East Indies and soon afterwards they took Rangoon, the capital of Burma. They had also made their first incursion into New Guinea in March when they landed troops in the Huon Gulf. By May most of Burma was under Japanese control and British troops had been pushed back to the Indian border.
Evans Carlson and Merritt Edson of the US Marines advocated the use of guerrilla warfare against the Japanese Army in the Pacific. Eventually Edson was given command of the 1st Raider Battalion whereas Carlson got the 2nd Raider Battalion.
Admiral Ernest King, Admiral Chester Nimitz, Commander in Chief of the US Pacific Fleet, and General Douglas MacArthur, Supreme Commander of the Southwest Pacific, decided that their first objective should be to establish and protect a line of communications across the South Pacific to Australia. This resulted in the battle of Coral Sea (6th-8th May, 1942).
In the summer of 1942 Admiral Isoruku Yamamoto decided to try and capture the US base on Midway Island. He believed that the Japanese Air Force would be able to launch air attacks on the US Fleet at Pearl Harbor. Yamamoto devised a complex plan where the Combined Fleet was split into eight task groups. Two of these groups made a diversionary attack on the Aleutian Islands. The rest of the fleet led by Yamamoto, Vice Admiral Chuichi Nagumo and Vice Admiral Nobutake Kondo, would head for Midway.
Unknown to Yamamoto the US intelligence service and broken the Japanese communication code and informed Admiral Chester Nimitz of the Japanese plans. Nimitz was able to assemble two task forces under Admiral Frank Fletcher and Rear Admiral
