A Mexican colonel in Nacogdoches told the people living there to bring in their guns and stack them.
That was the second of August, 1832, more than three years before anybody fired a shot at Gonzales. The Handbook of Texas says this fight is sometimes called the opening gun of the Texas Revolution. Sometimes called, which is a hedge worth keeping, because it is a contested title. The shape of what happened, though, is not in doubt.
