On orders of the Viceroy, Juan Francisco de Güemes, Friar Mariano Marti establish the San Francisco Xavier mission at a location on the San Gabriel River in what is now Milam County. The mission, located northeast of the future site of Austin, Texas, is attacked by 60 Apache Indians on May 2, and San Xavier is abandoned after a few years.

Dr. Samuel Johnson later writes, "The conflagration of a city, with all its turmoil and concominant distress, is one of the most dreadful spectacles which this world can afford to human eyes". Another history notes more than a century later that "the fire led to a great increase in the practice of fire insurance", after the blaze causes more than £1,000,000 worth of damage.
