The Aleutian Islands Campaign was a struggle over the Aleutian Islands, part of the Alaska Territory, in the American theatre and the Pacific theatre of World War II starting on the 3rd of June 1942. A small Japanese force occupied the islands of Attu and Kiska, but the remoteness of the islands and the difficulties of weather and terrain meant that it took nearly a year for a far larger U.S./Canadian force to eject them.
For the next nine months the Japanese were harassed from the sea, and from the air by USAAF bombers operating from air strips specially built on two other islands, Adak and Amchitka, just 145 km. (90 mi.) and 95 km. (60 mi.) respectively from Kiska. But adverse weather conditions hindered any real attrition of the occupying Japanese and it was not until March 1943 that sufficient Allied forces became available to drive them from American soil.
The weather made American air support unreliable as Rear-Admiral Charles McMorris discovered when it failed to arrive after he encountered Hosogaya's more powerful force on the 26th of March 1943. However, the battle of the Komandorski Islands which followed prevented the 2,630-strong Japanese garrison on Attu from receiving any further infantry reinforcements before 11,000 men of the 7th US Infantry Division landed there on the 11th of May 1943 with the support of a battleship bombardment and, for the first time in the Pacific war, with air support supplied by an escort carrier. The Japanese, commanded by Colonel Yamazaki Yasuyo, resisted stubbornly and on the 16th of May the commanding US General was dismissed when he remarked that it would need six months to conquer the island.
But Yamazaki and his men, outnumbered and poorly supported from the air and sea, were gradually pushed into the last high ground. Then, before dawn on the 29th of May, they launched one of the biggest banzai charges of the war which overran two command posts and a medical station before being halted. The battle went on all day and the next morning the surviving Japanese made a final attack before most of the survivors committed suicide. Only 28 prisoners were taken and 2,351 bodies were counted. The Americans lost 600 killed and 1,200 wounded.
Vice-Admiral Thomas Kinkaid, who had succeeded Rear Admiral Theobald in January 1943, now turned his attention to Kiska. He imposed a destroyer blockade and ordered intensified air and sea attacks on the garrison. However, by then the Japanese had decided to evacuate the island and on the night of 28/29th of July, while US naval patrol ships were refuelling after the ‘Battle of the Pips’, the Japanese Navy expertly evacuated 5,183 troops and civilians under cover of fog. Air reconnaissance failed to establish that Kiska was no longer occupied and as ground fire was reported on several occasions it was suspected that the Japanese might be hiding. So on the 15th of August 1943 a force of 34,000 US and Canadian troops landed, but it took them some days to discover the Japanese had departed. In doing so 56 men were killed or wounded when friendly patrols fired on one another.
