San Antonio merchant James Duff organized the 14th Texas Cavalry Battalion.

In summer 1862, the Texas government ordered the battalion to suppress the Union Loyal League, which was composed of German Texans who opposed secession.

When a group of Germans fled toward Mexico, Duff led a contingent of soldiers in a pursuit that ended in the so-called Battle of the Nueces in August 1862.

The 14th Battalion was subsequently expanded into the 33rd Texas Cavalry Regiment by the addition of some Mexican-American companies raised by Santos Benavides.
