The 12th Cavalry was one of several cavalry units that patrolled the Mexican border before, during and after World War I. 

The border was patrolled constantly, and because of the lack of roads in the area, the operations of the cavalry was the only practical and effective way to monitor the activity. 

In March 1920, major elements of the Regiment were deployed to Ft. McIntosh located in Del Rio, Texas - adjacent to the Rio Grande and the Mexican border, where they remained until 1921.
