On April 25, 1864, Confederate Brig. Gen. James Fagan ambushed a federal supply train heading from Camden toward Pine Bluff, Arkansas, at what became known as the Battle of Marks' Mill. Over 1100 prisoners eventually made their way to Camp Ford, Tyler, Texas, and some of those went on Camp Groce, Hempstead, Texas. Some escaped, many died, and the bulk of them were exchanged in February 1865. S. A. Swiggett, 36th Iowa Infantry, however, was the very last federal prisoner to leave Camp Ford in May, 1865. This presentation follows the men who were captured at Marks' Mill.
