How did the battle at the alamo the cause of texas independence

Though the Alamo story initially struck fear in the hearts of the Texans it subsequently led to a relentless thirst for vengeance

The Texan rebels lost this battle very badly. At the same time, they inflicted significant damages on Mexican forces, which may also have gained unfair confidence in their ability to suppress the Texan rebellion. But the biggest advantage this battle gave the Texans was their ability to portray the Mexican army's actions as a massacre of heroes. This allowed Texans to rally morale among its troops, leading to an eventual decisive victory over the Mexican army at The Battle of San Jacinto.

But all of the Texans' talk of heroism at the Alamo ignores, of course, how the Texan fighters were mostly American citizens who had illegally immigrated into Mexican territory and chose not to obey the laws of the Mexican government.
