Between 1858 and 1860, the army's new light-cavalry regiments were used for an offensive against Comanches in Oklahoma. In May, 1858 Colonel John Ford's Texas Rangers, ignoring the state-line, attacked a Comanche village on Little Robe Creek. Three months later his Caddo, Delaware, and Tonkawa scouts were expelled from Texas as undesirables. In October, 1858 Captain Earl Van Dorn attacked a Comanche village at Rush Springs killing 83. The following May, Van Dorn struck the Comanches at Crooked Creek in Kansas.
