John E. Garvin, Alamo defender, was born in 1809. At the time of the Texas Revolution he was a resident of Gonzales. On December 14, 1835, he joined the Texas artillery under Lt. Col. James C. Neill at San Antonio de Béxar. It is possible that Garvin left for Gonzales and returned to the Alamo on March 1, 1836, with the relief force. He died in the battle of the Alamo on March 6, 1836.
