Historical Note

The United States 4th Field Artillery was based in the Canal Zone at Corozal from 1916 to 1918. The unit returned to the Canal Zone in 1921 and was stationed at Fort Davis until it was deactivated in September, 1927. In the dry seasons of 1924, 1926 and 1927 they were deployed to Ft. Clayton for maneuvers, but afterwards returned to their permanent base at Fort Davis.
