Description (Aleutian Islands Campaign 3 Jun 1942 to 24 Aug 1943) On 3-4 June 1942, at the time of the Battle of Midway, a Japanese force attacked Dutch Harbor and inflicted considerable damage before it was driven off. The Japanese then occupied Attu and Kiska. For the rest of 1942 and into 1943, Eleventh Air Force struck enemy bases and installations whenever weather over the Aleutians permitted. The United States troops that landed on Attu on 11 May 1943 had possession of the island by the end of the month. The capture of Attu isolated Kiska, which was bombed repeatedly by American aircraft. The troops that invaded Kiska on 15 August 1943 discovered that the Japanese, under the cover of fog, had secretly evacuated their garrison.
