20th Company, Coast Artillery Corps, c. 1910.
The back of this card has a pencil-written message in Czech, which I can't read. The name appears to be Wiliam [sic] Schroeder. At this time there were only five field artillery regiments, so this must be a private of the 20th Company, Coast Artillery Corps, which before World War One was stationed at Fort Barrancas, near Pensacola, Florida.
