Thanks for this additional information. I had not read anything about the amount of illness at Ft. Pillow and afterwards in this unit. You would think that they would have kept better records of illness deaths than deaths on the battlefield.
Dale Cox, who is just finishing the 2nd addition of his book on the Battle of Marianna -
