In 1834, Vice President
Valentín Gómez Farías appointed Almonte and Col.
José María Díaz Noriega to make an inspection tour of Texas and write a status report on what they witnessed. In late January 1836 Almonte was appointed
aide-de-camp to
Antonio López de Santa Anna and accompanied him to Texas in an attempt to quell the rebellion there. Santa Anna led his army directly for
San Antonio de Bexar, where a small group of Texians was garrisoned at the former
Alamo Mission. As the Mexican army occupied the city, Texian co-commander
James Bowie sent Green B. Jameson to speak with Santa Anna. Instead, Jameson met with Almonte. According to Almonte, the Texians asked for an honorable surrender but were informed that any surrender must be unconditional. In his March 6 journal entry after the battle, Mexican Almonte listed the Texian casualty toll as 250, with the survivors being five women, one Mexican soldier and one slave. Almonte did not record the names of either the defenders or the survivors, and his count was based solely on who was there during the final assault. Almonte is said to have had the role in saving
Susanna Dickinson. According to some interviews she gave, a Mexican officer intervened to spare her and her daughter's life. This officer was presumed to be either an English mercenary named Black, or Almonte. Then, she said she was taken before Santa Anna, who was talked out of imprisoning her by Almonte. On April 21, 1836, Almonte, at the head of part of the Guerrero battalion, surrendered to Texian
Thomas Jefferson Rusk at the
Battle of San Jacinto. Almonte led the last organized resistance of the panicked army. On the following day Santa Anna also was taken prisoner. Almonte stayed with Santa Anna during his imprisonment acting as interpreter and negotiator. Almonte accompanied Santa Anna during his incarceration on
Galveston Island. Then they were taken up the Brazos river to the Phelps plantation, about 30 miles from Velasco, and kept there during the summer and autumn of 1836. While staying there the rumors spread that there were plans to rescue the prisoners. When an escape plot was later discovered, Almonte and Santa Anna were each forced to wear a heavy ball and chain for 52 and 53 days respectively. Finally, through the efforts of
Stephen F. Austin and
Sam Houston, Almonte, accompanied by Texas Vice-president
Lorenzo de Zavala and Bailey Hardeman was sent along with Santa Anna to Washington, D.C., where they had several meetings with U.S. President
Andrew Jackson. After eight days in Washington, they left the U.S. on January 31, 1837. The party returned to Mexico in February. By then, Santa Anna had been replaced as President of Mexico and went into retirement. Almonte, though, continued his diplomatic and military career and eventually rose to the rank of major general. He published a book on geography in late 1837. ==Minister of War==
