O'Brien's Alamo model
For the film, please see The Alamo.
The Alamo was the name of a fortified Spanish mission located in San Antonio in the North American region of Texas on Earth. In 1836, it was the site of the Battle of the Alamo.
In 2375, Miles O'Brien built a scale model of the mission. (DS9: "The Changing Face of Evil")
O'Brien and Bashir talked about visiting the real Alamo when O'Brien and his family left Deep Space 9 for Earth in late 2375. (DS9: "What You Leave Behind")
In the first draft script of "The Changing Face of Evil", the Alamo was established as having had 189 men protecting it during the Battle of the Alamo.
The Star Trek Encyclopedia (4th ed., vol. 1, p. 15) identified the Alamo as a Franciscan mission.
