John Hoptak at The 48th Pennsylvania Veteran Volunteer Infantry has an interesting post regarding Union prisoners, some taken at Bull Run, who were held for an unusually long period in “retaliation” for the treatment of Confederate privateers taken with the schooner Enchantress. Check it out; it’s good stuff. I wrote about some of these prisoners here, here and here.
This photo is from an 11th NY website, and shows prisoners from the regiment at Castle Pinckney. While one of the men is shown wearing baggy trousers and sash, it should be noted that the color of the 11th NY zouave uniform was gray, and most of the men were wearing blue pants during the battle.
