The Army unofficially adopted the castle to appear on the Corps of Engineers’ epaulets and belt plate in 1840. Soon afterwards the cadets at West Point, all of whom were part of the Corps of Engineers until the Military Academy left the charge of the Chief of Engineers and came under the charge of the Army at large in 1866, also wore the castle on their cap beginning in 1841. Subsequently, the castle appeared on the shoulder knot, on the saddlecloth, as a collar device, and on the buttons. Finally, in 1902, the castle was formally adopted by the Army as the insignia of the Corps of Engineers.
