This memorial, Spirit of Sacrifice, was commissioned in 1939 by the Texas Centennial Commission. Frank T. Drought served as consulting engineer and the sculpture was executed by San Antonio sculptor Pompeo Coppini. Resting on a base of pink Texas granite, the pedestal, inscribed with the names of those who perished at the Battle of the Alamo, and the vertical shaft are of gray Georgia marble. On the south face of the shaft is carved a twenty-three-foot-tall figure representing the Spirit of Sacrifice and a female figure symbolizing the State of Texas is represented on the north face. The dynamic upward thrusting geometry reinforces the raised arms of the high-relief figures. The east and west sides of the monument depict the defenders of the Alamo in bas-relief, with the major figures of James Bowie, James B. Bonham, David Crockett, and William B. Travis carved as nearly free-standing statues.
