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.
Yamasee War
The Tuscarora War and its lengthy aftermath played a major role in the outbreak of the Yamasee War. The Tuscarora, an Iroquoian-speaking tribe of the interior, began attacking colonial settlements of North Carolina in 1711. South Carolina settlers mustered armies and campaigned twice against the Tuscarora, in 1712 and 1713. These armies were made up mainly of allied Indian troops. The Yamasee had been strong military allies of South Carolina colonists for many years. Yamasee warriors made up the core of both Carolina armies. Other Indians were recruited over a large area from diverse tribes that in some cases were traditional enemies of one another. Tribes that sent warriors to South Carolina's armies included the Yamasee, Catawba, Yuchi, Apalachee, Cusabo, Wateree, Sugaree, Waxhaw, Congraree, Pee Dee, Cape Fear, Cheraw, Sissipahaw, Cherokee, and various proto-Creek groups.
