While the location—a little more than 10 miles from the Mason-Dixon Line—might not immediately spring to mind when thinking of areas of historic Italian American significance, the grounds of the Letterkenny Army Depot tell a much different story.

During World War II, the United States government interned more than 1,200 captured Italian soldiers at Letterkenny. From May 1944 to October 1945, these soldiers became part of the 321st Italian Quartermaster Battalion, originally commanded by Lt. Col. Salvatore Campa and then by Maj. Angelo Bassi. The 321st was then divided into six Italian Service Units (ISUs) that provided assistance at the new Depot.
