Final answer:
Sam Houston led the Texans to victory at the Battle of San Jacinto, securing Texas's independence from Mexico and setting the stage for the eventual annexation of Texas into the United States.
Step-by-step explanation:
The leader who led the Texans to victory at the Battle of San Jacinto was Sam Houston. This battle took place on April 21, 1836, and was a decisive moment in the Texas Revolution against Mexico.
During the battle, Sam Houston's strategy proved successful as the Texan army, despite being outnumbered, launched a surprise attack against General Antonio López de Santa Anna's Mexican forces, who were resting.
The Texans, fueled by the rallying cry "Remember the Alamo!" achieved a swift victory, effectively securing independence for Texas from Mexican control. Interestingly, both William Travis and Jim Bowie played significant roles in the earlier and ill-fated defense of the Alamo, where they both lost their lives, rather than the San Jacinto battle. The success at San Jacinto paved the way for the establishment of the independent Lone Star Republic and, eventually, the annexation of Texas into the United States of America.
