Francisco, the Quechan tribesman who "rescued" Olive Oatman by threatening the Mojaves and predicting annihilation if they didn't release her, became quite full of himself and went around preaching and talking down to the various river tribes. He boasted of his prowess at war and preached revenge and finally talked the Yumans and the Mojaves into going to war against the Maricopa and Pima tribes. Francisco's combined war party attacked at Maricopa Wells and in an all day In-din fight the Pimas and Maricopas prevailed and killed over 200 of the best warriors on the Colorado River.
There are no known photographs of Francisco, but this image, above, perfectly captures his visage, in my opinion.
