The American Soldier, 1814: The war of 1812 was the cradle of the Armyâ€™s General Staff. Staff departments and staff procedures comparable to the best available in European armies were developed. A general staff officer stands in the left foreground. The uniform was adopted in 1813 and worn for the next two decades. Behind him is a mounted general officer. Both men wear the high military boots allowed only to general and general staff officers. An old American institution, the rifle regiment, reappeared on the rolls of the Army in the years leading up to the War of 1812. So well liked was this type of unit that three more regiments of riflemen were created during the war. In the right foreground is a rifle regiment field grade officer in the gray dress uniform adopted for those regiments in March 1814. A detachment of riflemen in their fringed, green summer linen rifle frocks, the only reminder of the green uniform formerly worn by the rifle regiment, are seen in the background.
