Battle of the Komandorski Islands
With the Americans moving closer towards Kiska and Attu, the Japanese were finding it increasingly difficult to resupply their bases there. In March 1943, Admiral Thomas C. Kinkaid established a naval blockade around the islands, refusing to let Japanese ships through. On March 26, Admiral Hosogaya attempted to break the blockade with eight battle ships as well as three transports, resulting in the Battle of the Komandorski Islands, the last battle fought only between surface ships in the Pacific War. Following the American victory in this battle, the Japanese were forced to resupply their occupied possessions in the Aleutian chain by submarine.
