Confederacy, Immortal "Confederate 600" - Steamer Crescent City. Orange cover with endorsement by "Capt. H.C. Dickinson/Co. A, 2nd Va. Cavalry" as a prisoner held on board the "Steamer Crescent City" off Morris Island, addressed to his wife in Liberty, Va., postmarked with "Charleston, S.C./Sep. 2, 1864" cds and "Paid 10" in circle handstamp, endorsed "By flag of truce", unsealed for censoring, Extremely Fine. Estimate  $2,000 - 3,000. The "600" was a group of 600 prisoners, all Confederate officers, moved to from Fort Delaware to be sent to Morris Island in Charleston harbor in August 1864 and held in open barracks exposed to mortar fire from Confederate batteries. This is one of only four recorded covers sent from the "Steamer Crescent City", prior to the transfer of Prisoners to Morris Island on September 7, 1864. This extraordinarily inhumane act was the Federal response to an equally repulsive act on the part of Confederates in Charleston, who exposed Union prisoners to bombardment from Federal forces within range of the city. This sorry chapter of the war ended in a stalemate in October 1864. Covers from Confederate prisoners en route to and from or imprisoned on Morris Island are very rare. . $0 (Image)
