Operation Cottage was the code name for the last operation of the Aleutian Island Campaign in which the Allies invaded Kiska island. The operation lasted for a few days from its beginning on August 15, 1943 to August 17, 1943. Perhaps the most notable aspect of the operation was that just prior to the Allied invasion, the entire Japanese garrison had abandoned the island, leaving only empty fortifications and mined paths to traverse. Regardless, even with no actual Japanese on the island, the Allies suffered over 300 casualties.
