Canadian troops boarding a ship for the Aleutians. U.S. Army helmets were provided to the Canadians.
The landings occurred on August 15 - 16, 1943. To the surprise of the allied forces, the Japanese defenders had evacuated the island.
Canadian forces remained in the Aleutians until January 14, 1944, and received postal service from Canadian Army Post Office No. 51. Surface mail was sent free but air mail letters required 6 cents U.S. postage. Mail was censored at the unit level as well as by the U.S. Army. Mail was processed through the U.S. Army Post Office at Adak Island. (Reference Bailey & Toop, Proud Series, The Canadian Military Posts, Volume 2)
