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.
Drum Barracks
After the Civil War, Camp Drum remained active for several years in the Indian Wars. By 1870, it had been deactivated and fallen into disrepair. In October 1871, the "Los Angeles Star" reported that all remaining troops at Drum Barracks had been ordered to Fort Yuma.
