From the Richmond Dispatch, 3/27/1862
C. S. Military Prison. – The Yankee prisoners at present sojourning here, some 500 in number, were yesterday transferred from the factories on Main street, so long occupied by them, to Libby & Son's warehouses, on Cary street, below 20th, near the Dock, a locality secluded from observation, and where only half the former number of men need be retained for guard duty to ensure the safety of the prisoners, the building being all connected together.
