Historical Note

The 10th Infantry was stationed in the Canal Zone at Camp Otis from October 1911 until May 1917. Upon arrival from its original station in Texas, the 10th Infantry consisted of 33 officers and 813 enlisted men. The camp was named for Major General Elwell S. Otis (1838-1909), a veteran of the Civil War and the Philippines. Camp Otis was an old labor camp named Las Cascadas which was turned over to the US Army in 1911, after there was no more use for it in the Panama Canal construction effort. In 1917 the 10th Infantry was redeployed to France as part of the American Expeditionary Force.

Population Count Only one specimen in collector hands is known to me. I do not know of any recent sales.
