Yuma War
The Yuma War was the name given to a series of United States military operations conducted in southern California and what is today southwestern Arizona from 1850 to 1853. The Yumans were the primary opponent of the United States Army, though engagements were fought between the Americans and other native groups in the region. Conflict generally took the form of guerrilla warfare, and, over the course of three years, the army engaged in pursuing unfriendly natives, protecting American settlers crossing the Colorado River and preventing conflict between the native tribes. A peace treaty in summer of 1853 was signed, ending hostilities between the Yuma and the United States, but it sparked a short war between the Yuma and the Cocopah. During the conflict, the historic Fort Yuma was constructed and became an important outpost on the frontier.
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.
