Through mid-1943, Indianapolis remained near the Aleutian Islands, escorting American convoys and providing shore bombardments supporting amphibious assaults. In May, the Allies captured Attu, then turned on Kiska, thought to be the final Japanese holdout in the Aleutians. Allied landings there began on 15 August, but the Japanese had already abandoned the Aleutian Islands, unbeknownst to the Allies.[13]
