VERY FINE. AN OUTSTANDING COVER WHICH WAS ONE OF THE LAST PIECES OF REGULAR MAIL TO CROSS THE BORDER FROM THE CONFEDERATE STATES INTO THE UNITED STATES, SHOWING THE POSTAGE RATES OF BOTH GOVERNMENTS.
This cover was mailed from Vicksburg on June 8, seven days after the establishment of the Confederate postal system. It would normally have passed through Memphis, Tennessee. However, since the U.S. suspended service at that office on June 6, the letter was routed through Nashville, most likely arriving on June 10. It then went through Louisville on June 12 and to its destination in Pa. without penalty (there are other covers with almost the same dates that were diverted to the Dead Letter office after leaving Louisville). On June 12, 1861, the U.S. suspended service at the Nashville post office, which effectively closed down the last remaining northbound mail route from the Confederate States. The Nashville postmaster continued to forward northbound mail, but letters were stopped at Louisville starting on June 13, one day after this cover was allowed to go through.
From a new find. With 2009 C.S.A. certificate
