Outnumbered roops under Ranald Mackenzie attacked Cheyenne, Kiowa and Comanche at Palo Duro Canyon bringing about a legendary and significant Army victory in the Red River War and essentially bringing it to a close.
Casualties on both sides were overall light, but the loss of horses and supplies was devastating to the Native side.
Mackenzie is forgotten in the popular memory, although he certainly is not amongst students of the post Civil War Indian Wars. He was an extremely effective but died a bad death at age 48, which may be part of the reason that he's forgotten.
