Yuma Crossing
Immediately after the Mexican–American War in 1848, the U.S. Army built Fort Yuma here to protect travelers from Indians raiding the area. It was the center point of conflict in the Yuma War of 1850–53. From 1864–1890, the fort and nearby facilities was the main army base to support the US Army's efforts to control the Indians throughout the greater southwest.
USS Yuma (1865)
USS "Yuma", a single-turreted, twin-screw monitor, was laid down at Cincinnati, OH, by Alexander Swift and Co. and launched on 30 May 1865. A "Casco"-class, light-draft monitor, she was intended for service in the shallow bays, rivers, and inlets of the Confederacy. These warships sacrificed armor plate for a shallow draft and were fitted with a ballast compartment designed to lower them in the water during battle.
