Apache warriors, over 200 strong, attacked Tubac sometime in early August 1861 and initiated a siege on one side of the
presidio. Mexican bandits occupied the other side but stayed out of the major fighting. The towns people fought the Apaches for three days until sending a dispatch rider to
Tucson, requesting reinforcements. A force of 25 militiamen, carrying a
Confederate flag and commanded by Captain
G. H. Oury, arrived at the town and fought off the final assault. The Apaches withdrew out of close range but continued to lay siege by stopping the ability of the militia to escape. Eventually, food and ammunition became short, and the
garrison, women and children chose to flee to avoid being completely massacred by the overwhelming Apache warriors. The Arizonans escaped successfully after another skirmish on the last night, leaving Tubac to be burned by the Natives and plundered by the Mexican bandits. The Americans headed back to Tucson, to the north, having completed their objective of rescuing the besieged Tubacans. The casualties of the engagement are unknown. ==Aftermath==
