(SOLVED) color Western from the 1940s-1960s in which the army tries to fight a group of Native Americans and loses
A large body of U.S. soldiers, at least several hundred if I remember correctly, tries to attack a group of armed Native Americans somewhere in the desert or some other desertish environment. There were several engagements in which the army lost badly every time. I don't remember even a single Native American being killed or wounded. The Native American attacks were extremely well-coordinated and well-targeted.
There was an African American scout with the army. At least, I assume he was a scout for the army. He wasn't a soldier because he wasn't in uniform. During one of the battles he was shot in the arm with an arrow.
The Native Americans won in the end when the army just gave up and left.
