 According to the Maryland Department of Natural Resources, of the 50,000 soldiers held in the army prison camp at Lookout Point, all of whom were housed in tents, nearly 4,000 died.The death rate of 8 percent was less than half of the death rate among soldiers who were in the field with their own armies.The camp, originally built to hold 10,000 men, swelled to between 12,000 and 20,000 prisoners after the exchange of prisoners between armies was placed on hold.
