Two or three small islands were captured and were worthless to Japan.
If I remember this right we attacked and took one back & the other two (or one) was abandoned.
Yeah, they couldn’t have kept their new holdings supplied, and there was no strategic advantage to even being there. The forces used to capture the Aleutians would have been better used at Midway, but the Army had to have its due.
Attu, the westernmost of the two islands produced a bloody battle in May 1943 which lasted most of a month. Kiska, the island further to the east, was quietly evacuated. Operation Cottage, to invade and retake the island in August produced 313 allied casualties in total due to landmines and booby traps left behind, friendly fire, motor vehicle accidents, etc.
