Fourth Battle of Tucson
March 21, 1784
The Catalina Mountains.
The Fourth Battle of Tucson was a raid during the lengthy wars between Spanish colonists in Arizona and its region and Apache Indians. At break of day, on March 21, 1784, a force of no more than 500 Apaches and Navajos attacked Spanish cavalry guards protecting a herd of livestock at the Presidio San Augustin del Tucson in southern Arizona. The Native forces succeeded in capturing 13 horses, leaving five soldiers dead and one wounded.
