During the Texas Revolution, a small garrison of roughly 180 Texian volunteers, including prominent figures like Davy Crockett and Jim Bowie, was besieged inside the Alamo mission in San Antonio, Texas, by a massive Mexican army under General Santa Anna. For thirteen days, the vastly outnumbered defenders endured continuous artillery bombardment, extreme sleep deprivation, and freezing winter temperatures while maintaining their crumbling perimeter. On March 6, the siege culminated in a brutal, pre-dawn infantry assault; the exhausted defenders held out through fierce hand-to-hand combat until the garrison was entirely wiped out, creating an enduring symbol of military steadfastness.

The tragic defense and absolute sacrifice at the Alamo instantly catalyzed a wave of nationalistic American poetry, journalistic lore, and folk ballads centered on the phrase 'Remember the Alamo!'. Walt Whitman explicitly memorialized the fierce, tragic nature of the Texian struggle in Section 34 of his masterpiece 'Song of Myself', incorporating the raw narrative of frontier endurance and military martyrdom directly into the democratic canon of American poetry.
