Civil War Union Army Frock Coat, c. 1861-1865, Wool, silk, velvet, metal, and brass, 40 x 16 inches, Gift of George Millener, 1972.15.12.
Worn by a Union Army First Lieutenant, the navy color of this thigh-length frock coat would have helped identify its owner to both friends and enemies on the battlefield. Union and Confederate uniforms used buttons and other insignia as symbols of rank.
