Meanwhile the search for Agatón continued. In a letter from a loyal Mexican of San Antonio de Béxar, dated July 1, General Rafael Vasquez was informed that the next day Antonio Parez would leave Béxar with a few less than two hundred men, including thirty Mexicans and the rest Americans, "with the sole object of surprising the force under Agatón Quinoñes."

The informer also reported that one thousand men, including five hundred soldiers and the rest muleteers and merchants, had left for New Mexico twelve days before. [Ed: The Santa Fé Expedition]

From Sabinas on April 13 he issued a proclamation to his troops and to the people of the eastern frontier departments warning them to cease their trade with the Texans and reminding them that the penalty for such a crime was ten years' service in the regular army on the frontier, and confiscation of the goods, beasts, and all effects used in conducting the trade. The Mexicans refused to sell any land west of the Nueces to any person who would not become a citizen of Mexico, and repeatedly asserted that no person would be permitted to live west of that river unless he acknowledged the authority of Mexico.

The Mexican troops descended upon Kinney's rancho. At the ranch, their leaders became convinced
