Richmond Prisons and Hospitals during the Civil War

A map of the Richmond warehouse district along the James River indicates the location of various prisons in pink—Castle Thunder, Libby Prison, Scott's Factory Prison, and Crew & Pemberton's Prison—and in yellow the hospitals designated for Union captives. This watercolor drawing was made by Union private Robert Knox Sneden, who was captured by John Singleton Mosby's rangers at Brandy Station in November 1863, and incarcerated in Crew and Pemberton's Prison (shown bottom right) that winter.
