Camp Grant Massacre (1871)
After horse-stealing raids around Tucson, a party of 148 Anglos, Mexicans, and Papago indians blamed Eskiminzin's band of Apaches living on the Camp Grant Reservation. While Eskiminzin and his warriors were absent, the vigilante mob murdered as many as 150 Apaches, mostly women and children.
All of the participants in the massacre were acquitted in a trial a year later.
