These events should not be confused with the Skeleton Canyon Shootout in 1896.The Skeleton Canyon massacres refer to two separate attacks on Mexican citizens in 1879 and 1881. Skeleton Canyon is located in the Peloncillo Mountains (Hidalgo County), which straddles the modern Arizona and New Mexico state line border. This canyon connects the Animas Valley of New Mexico with the San Simon Valley of Arizona.
The first Skeleton Canyon Massacre occurred in 1879 when a group of Mexican Rurales were ambushed by cattle rustlers. In July 1879, several rustlers attacked a rancho in northern Sonora, killing several of the inhabitants. After the attack on the rancho, the survivors reported the attacks to Commandant Francisco Neri, who sent out a detachment of Rurales, including Captain Alfredo Carrillo. The Rurales crossed the border into Arizona. As they entered Skeleton Canyon, shots were fired against them. Of the large group that crossed, only three of the Rurales survived.
No action was taken by the Mexican Government, but it protested the killings to President Chester Arthur, although acknowledging the Mexican policemen had crossed into Arizona. Johnny Ringo, considered to be one of an outlaw group known as the Cochise County Cowboys, who were cattle rustlers and bandits, claimed to have been at the ambush. He said others there who participated in the murders were Old Man Clanton, brothers Ike and Billy Clanton, "Curly Bill" Brocius, Florentino Cruz, and brothers Frank and Tom McLaury.[1]
In July 1881, "Curly Bill" Brocius learned that several Mexican smugglers carrying silver were heading to Arizona through Skeleton Canyon. Curly Bill and around twenty other men including Johnny Ringo and Jim Crane ambushed the smugglers, killing four and stealing $4,000 in bullion and livestock. Two months after the attack was reported by the surviving smugglers, Commandant Neri again sent a detachment of Rurales led by Captain Carrillo across the border. This time, the Rurales successfully ambushed the Cowboys, killing five including Old Man Clanton and Jim Crane, in what became known as the Guadalupe Canyon Massacre.[2]
