In the spring of 1832, Wm. B. Travis, Patrick C. Jack, and other American settlers in Texas were unjustly imprisoned by Col. Juan Bradburn, commander of the Mexican garrison at Anahuac. Bradburn's refusal to deliver his prisoners for civil trial caused alarm throughout the American settlements, resulting in the organization of an armed force of citizens to intervene and save their friends from trial by a military court in Mexico. Rallying at Liberty, the Texans on June 10 went to Anahuac to parley with Bradburn, who agreed to free the colonists in exchange for Mexican soldiers held by the Texans. When Bradburn refused to keep his word, the Texans resolved to fight and sent to Brazoria for reinforcements of men and cannon, thus precipitating the Battle of Velasco on June 26, 1832. These events were climaxed by the arrival of Piedras, Mexican military commander from Nacogdoches, who resolved the conflict by releasing the colonists and placing Bradburn under arrest. Mexican resentment aroused over the events at Anahuac and Velasco was a contributing factor in the subsequent war for Texas Independence.
