Houston goes to Mexican Territory at the suggestion of his friend, President Andrew Jackson. He soon becomes involved in the cause of Texas independence, but in opposition to Stephen Austin, who believes Texas can gain autonomy under Mexican rule. After Austin is imprisoned by the Mexicans, Houston is appointed commander-in-chief of the Texas forces in their fight for freedom. When Houston's orders are ignored, the Alamo falls. However, he rallies his forces and engages a much larger Mexican force under the wily Santa Ana, in a battle in which he employs brilliant military strategy.
