Boatswain Piping on a U.S. Naval Warship During the American Civil War The image depicts a boatswain performing piping duties, accompanied by other sailors, on the deck of a United States Navy warship during the American Civil War (1861-1865). Boatswains were responsible for managing the crew and the ship's rigging. In this context, the boatswain is likely calling out orders or instructions using a pipe (a long, hollow tube) as a signal device. The large cannon in the foreground suggests the warship was either at sea or on a military installation during wartime. This photograph offers a unique insight into the daily life and hierarchical structure of sailors aboard U.S. naval vessels during the American Civil War.
