and inflicted heavy damage on Japanese warships and transports, losing few aircraft. Indianapolis returned to the Mare Island Naval Shipyard for a refit before escorting a convoy to Australia. Aleutian Islands campaign Indianapolis then headed for the North Pacific to support American units in the Battle of the Aleutian Islands. On 7 August, Indianapolis and the task force attacked Kiska Island, a Japanese staging area. Although fog hindered observation, Indianapolis and other ships fired their main guns into the bay. Floatplanes from the cruisers reported Japanese ships sunk in the harbor and damage to shore installations. After 15 minutes, Japanese shore batteries returned fire before being destroyed by the ships' main guns. Japanese submarines approaching the force were depth-charged by American destroyers and Japanese seaplanes made an ineffective bombing attack. In spite of a lack of information on the Japanese forces, the operation was considered a success. US forces later occupied Adak Island, providing a naval base farther from Dutch Harbor on Unalaska Island. 1943 operations In January 1943, Indianapolis supported a landing and occupation on Amchitka, part of an Allied island hopping strategy in the Aleutian Islands. On the evening of 19 February, Indianapolis led two destroyers on a patrol southwest of Attu Island, searching for Japanese ships trying to reinforce Kiska and Attu. She intercepted the Japanese cargo ship, laden with troops, munitions, and supplies. The cargo ship tried to reply to the radio challenge but was shelled by Indianapolis. Akagane Maru exploded and sank with all hands. 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. After refitting at Mare Island, Indianapolis moved to Hawaii as flagship of Vice Admiral Raymond A. Spruance, commanding the 5th Fleet. She sortied from Pearl Harbor on 10 November, with the main body of the Southern Attack Force for Operation Galvanic, the invasion of the Gilbert Islands. On 19 November, Indianapolis bombarded Tarawa Atoll, and next day pounded Makin (see Battle of Makin). The ship then returned to Tarawa as fire-support for the landings. Her guns shot down an enemy plane and shelled enemy strongpoints as landing parties fought Japanese defenders in
