19 September 1871; Southwestern Oklahoma: Capt. John B. Vande Wiele of Company B, 10th Cavalry, and a patrol from Otter Creek Camp in Oklahoma were scouting southeast toward the Red River. On 19 September, Kiowas and Comanches ambushed three troopers who were riding ahead of the rest. Kiowa warrior An-pay-kau-te killed bugler Larkin Foster, while the soldiers killed two warriors and wounded three.
Col. Benjamin Grierson was so angry at the death of one of his 10th Cavalrymen that he wanted to strike the Kiowas at Fort Sill, but Indian agent Lawrie Tatum talked him out of it.
