In August 1943 troops of Pacific Command participated in Operation Cottage, in the final stages of the Aleutian Islands campaign. However, that campaign ended without a shot being fired at the enemy when it was discovered that the Japanese occupiers of Kiska had already evacuated the island. The only "enemy" the Pacific Command troops inflicted upon physically were American forces, after a Canadian soldier mistakenly shot at American lines, causing a sporadic friendly fire incident between the two forces that left 28 Americans and four Canadians dead, with 50 others injured.
