The last big battle between the Colorado-Gila River alliances took place in August 1857, when about 100 Yavapai, Quechan, and Mohave warriors attacked a settlement of Maricopa near Pima Butte. After overwhelming the Maricopa, the Yavapai left. A group of Pima, supplied with guns and horses from US troops, arrived and routed the remaining Mohave and Quechans.
