William B. Travis (August 1, 1809 - March 6, 1836) was a 19th century soldier who led the Texan forces at the Alamo during its siege by the Mexican leader Antonio López de Santa Anna. Travis died during the famous battle.
Julian Bashir often played Travis and Miles O'Brien would play Davy Crockett in Deep Space 9's holosuites. They would also discuss Travis and the Battle of the Alamo outside the holosuites as well. (DS9 episodes: "Afterimage", "Once More Unto the Breach", "Extreme Measures")
Just before the Second Battle of Chin'toka in 2375, O'Brien had built a model of the Alamo and created several figures, including one of Travis. The figure was later lost and O'Brien blamed Bashir. (DS9 episode: "The Changing Face of Evil")
