V Velasco, Treaties of Two treaties, one public, the other secret, were signed by Santa Anna and interim president David G. Burnet on May 14, 1836. In the public treaty, Santa Anna agreed to cease all hostilities against Texas, then and in the future. Mexican troops would be withdrawn south of the Rio Grande, confiscated property would be restored to the Texan owners, and prisoners would be exchanged. Texas agreed to return Santa Anna to Mexico as soon as possible, and Texas army units would approach no nearer than five leagues to the retreating Mexican army. In the secret treaty, Santa Anna agreed to secure Mexican recognition of Texas independence and a permanent end to the war. The Mexican cabinet would receive a Texas mission to conclude a treaty of commerce and limits, Texas boundaries to extend no further south than the Rio Grande. Although the Mexican retreat was begun almost immediately, the Texas Army refused to allow Santa Anna’s return to Mexico. On May 20, the Mexican government declared all Santa Anna’s acts as a captive to be null and void.
