While I don't have total of all prisoners according to a book I own. The total of Texas troops are around 551. Reason I say "around" is because there are few unknows buried at Camp Douglas and some may be from Texas Some prisoners excaped from there and few were said to have excaped after surrender at Arkansas Post. Some were reported to have excaped on the way to Camp Douglas. Some managed to excape during the confusion at end of battle,also.
