FINE. AN EXTREMELY RARE EXAMPLE OF MAIL CARRIED COVERTLY FROM FORT SUMTER AFTER CONFEDERATE FORCES CUT OFF COMMUNICATIONS IN JANUARY 1861.
In retaliation for Union forces moving from Fort Moultrie to Fort Sumter, the governor of South Carolina ordered all mail communication with Fort Sumter suspended on January 1, 1861, but mail exchange was allowed to resume on January 14. This cover was carried privately, as indicated in the copy of the letter (the original is located in the Library of Congress).

VERY FINE. AN OUTSTANDING AND VERY EARLY COVERT THROUGH-THE-LINES COVER FROM THE UNION BLOCKADE OF PENSACOLA, CARRIED THROUGH CONFEDERATE FLORIDA AND MAILED FROM THE STILL-OPERATING U.S. POST OFFICE IN MONTGOMERY, ALABAMA.
This is a rare and very early covert through-the-lines use as well as a Confederate post office use of U.S. postage. It was facilitated by Warrington postmaster W. H. Lamberton and posted at Montgomery Ala., as the U.S. post offices at Pensacola and Warrington had both been closed by Jan. 29, 1861. Shortly after this was sent, any assistance for the Union blockade ships, including correspondence going north, was strictly forbidden by General Braxton Bragg in a General Order dated March 18, 1861.
Ex Dr. Briggs. Accompanied by a Feb. 17, 1860 postmarked 3c Nesbitt entire from Warrington Fla. to Cincinnati from the same correspondence, with letter enclosure datelined "On Shore. Warrington Navy Yard." Also accompanied by an article from The Confederate Philatelist (Oct.-Dec. 2012) describing this correspondence.
