Ustinov was a private in newly promoted Corporal Armstrong Grimes' squad. During a Mormon barrage by spigot mortars, Ustinov was seriously wounded, losing a hand. While still under bombardment, Grimes crawled out to Ustinov, applied a tourniquet to his arm, and then crawled back to the U.S. position with him on his back.
