Battle of Medina

The Battle of Medina was fought approximately 20 miles south of San Antonio de Bexar on August 18, 1813, as part of the Mexican War of Independence against Spanish authority in Mexico. Spanish troops led by General José Joaquín de Arredondo defeated republican forces , consisting of Tejano-Mexican and Tejano-American revolutionaries participating in the Gutiérrez–Magee Expedition, under General José Álvarez de Toledo y Dubois. It was the deadliest battle in Texas history.

Bernardo Gutiérrez de Lara took up the effort to free Texas from Spain. Colonel Gutiérrez visited Washington, D.C., gaining some support for his plans. In 1812, Colonel Augustus Magee, who as a lieutenant had commanded U.S. Army troops guarding the border of the Neutral Ground and Spanish Texas, resigned his commission and formed the Republican Army of the North to aid the Gutiérrez–Magee Expedition. The army flew a solid emerald green flag, thought to have been introduced by Colonel Magee, who was of Scots-Irish descent.
