Louis Leon diary: http://docsouth.unc.edu/fpn/leon/leon.html
July 29 – There are at present some 3,000 prisoners here. I like this place better than Point Lookout. We are fenced in by a high fence, in, I judge, a 200-acre lot. There is an observatory outside, and some Yankee is making money, as he charges ten cents for every one that wishes to see the rebels.
