In many ways, the prison camp was like its own city with a library, hospital and market. The economy ran on tobacco and barter. Prisoners worked for the camp administration as carpenters, clerks, hospital attendants, waiters and cooks. Others ran their own businesses as barbers, tailors, hunters, teachers or makers of handmade jewelry. Still, it was a poor city where food and clothes were scarce and nearly everyone had lice. Many prisoners suffered from diseases like dysentery and smallpox and nearly everyone had scurvy.
