On 28 July 1943, the last Japanese troops were evacuated from Kiska. Allied forces did not detect the evacuation and launched a full-scale invasion of unoccupied Kiska in Operation Cottage on 15 August 1943, but Japanese involvement in the Aleutians campaign had ended with the 28 July evacuation. On 10 August 1943, "I-169" arrived at Kure for an overhaul.
