Degüello. Reproduced in Amelia Williams, “A Critical Study of the Siege of the Alamo,” Southwestern Historical Quarterly 37 (January 1934). The playing of this Mexican bugle call, announcing that no quarter would be given the rebellious Texans, signaled the final assault on the Alamo.

DEGÜELLO. The degüello, music played by the Mexican army bands on the morning of March 6, 1836, was the signal for Antonio López de Santa Anna's attack on the Alamo. The word degüello signifies the act of beheading or throat-cutting and in Spanish history became associated with the battle music, which, in different versions, meant complete destruction of the enemy without mercy.
