Michael McCarthy was a soldier stationed at Fort Walla Walla with the 1st U.S. Calvary. As a Sergeant during the Nez Perce War in 1877, he was involved in the fierce struggle at Whitebird Canyon, the first major encounter of the war, near Lewiston where the cavalry lost 34 men. He was later awarded a Congressional Medal of Honor for his heroism in saving many troopers’ lives during that battle, and retired in Walla Walla as a colonel.
