The Flag of the
Gutíerrez-Magee Expedition

In 1812, a filibustering expedition led by Mexican revolutionary Bernardo Gutíerrez de Lara and a 24 year old U.S. Army officer named Augustus Magee liberated Texas from Spanish rule for one year. Under this green flag, the "Gutíerrez-Magee Expedition" ruled Texas until they met defeat south of San Antonio at the Battle of the Medina in 1813. Among the Spanish officers of General Joaquín de Arrendondo's army who crushed the "Green Flag Republic" was a young Spanish Lieutenant named Antonio Lopez de Santa Anna.
