[1] Juan Antonio's Mountain Cahuilla were settled in Politana in 1845, to protect the herds of horses and cattle of the Rancho San Bernardino from the raids of bandits and the native tribes from the nearby mountains, the Mojave Desert and Utah.

A militia force from San Diego County was sent to quell this supposed uprising, led by Joshua Bean.

Judge Hayes held a hearing and subsequently found their actions had legal justification.

There Juan Antonio and his people remained until the winter of 1862–1863, when a smallpox epidemic swept through Southern California killing many, especially the Native American population who had little immunity to the disease.

In 1956 an archeological expedition discovered Juan Antonio's body at Saahatpa, identified by his epaulets.
