"named for the Texas Navy, my very first customers of any note, who used my guns to crush the Mexicans at Campeche"

 The Texas Navy was the navy of the Republic of Texas, which existed from 1836, when it broke away from Mexico, until its incorporation into the United States in 1846.

When Texas revolted, it found itself at war with Mexico, who initially refused to let it secede. During this war, the Texas Navy was instrumental in preventing Mexico from recapturing the Republic. The ensuing Battle of Campeche is thought to be unique in seeing Mexican steamships fighting against Texan sailing ships. A scene from this battle is engraved on the cylinder of the Colt 1851 Navy Revolver to commemorate the Navy's use of Colt's Paterson revolvers.
