In 1851, near the Piños Altos mining camp, Coloradas was attacked by a group of miners; they tied him to a tree and severely beat him. Similar incidents continued in violation of the treaty, leading to Apache reprisals against European Americans. In December 1860, thirty miners launched a surprise attack on an encampment of "Bedonkohe" on the west bank of the Mimbres River in retaliation for the theft of numerous livestock. According to the historian Edwin R. Sweeney, the miners "...killed four Indians, wounded others, and captured thirteen women and children." The Apache quickly retaliated with raids against U.S. citizens and property.
