Navarro later served as a leader in the Texas Revolution. He was at the Convention for Texas Independence, when he received the news from Juan Seguin of the Alamo's fall. With the death of James Bowie (his nephew by marriage), Navarro had to secure the release of the surviving Navarros, two women and a child, who were being held by the Mexican army at the Músquiz house. They were removed to the Navarro family home. The surviving noncombatants thereby avoided execution as traitors to Mexico by General Antonio López de Santa Anna.
