This is an interesting and odd statement because it was Sam Houston who was also instrumental in the annexation of Texas in 1845.
Explanation:
Sam Houston was the leader of the Texan Army and helped to win independence from Mexico with victories like that at Battle of San Jacinto. Houston is a figure of Texan Independence but also of the annexation of Texas to the United States. Houston served as president of Texas twice. He was also elected to the Senate to represent Texas in 1846. The whole quote is as follows: "There would be no difficulty in securing the rights of the people and the liberties of Texas if men would march to their duty and not fly like recreants from danger. Texas must be defended and liberty maintained." He was inciting others to join the cause for Texan independence.
