Col. John I. Gregg 1872 Battle Site. The decade after 1865 was a time of transition for the U.S. Many citizens moved west, coming into conflict with Native American tribes living on the Great Plains. Settlers demanded the U.S. Army provide their protection. The Army responded by conducting campaigns against the Southern Plains Indians. In 1872, one such campaign included troops of the Eighth Cavalry commanded by Colonel John I. Gregg, who departed from New Mexico into West Texas to locate Native American raiders. On August 16, his troops skirmished here with Kiowas, killing or injuring twelve while suffering one wounded. This and the Red River War (1874-75) led to the subjugation of Plains Indians and their confinement to reservations. (2006) #13664
