VERY FINE. A RARE EXAMPLE OF TRANS-RIO GRANDE MAIL CARRIED FROM MEXICO TO CONFEDERATE NEW ORLEANS VIA TEXAS AND ACROSS BERWICK'S BAY. EXTREMELY UNUSUAL WITH THE MANUSCRIPT ROUTE DIRECTIVE.
This July 1861 cover is an early example of mail carried across the Rio Grande from Matamoros to Brownsville, which entered the C.S.A. postal system and was transported to New Orleans. The route indicated on the cover, "via Berwick's Bay", was the well-established "Texas and New Orleans Great Southwestern Passenger Route" across the Atchafalaya River via Berwick City and Brashear (later renamed Morgan City). This is the only trans-Rio Grande cover we have seen with this directive (a later cover from this correspondence has a "via Corpus" directive).
VERY FINE. A LATE TRANS-RIO GRANDE FOLDED LETTER THAT MENTIONS THE SURRENDER OF LEE'S ARMY.
This letter, written in Spanish, mentions receiving news of the "capitulacion de Lee", referring of course to Lee's surrender at Appomattox on April 9, 1865. The war would carry on another month in Texas, with the last battle -- the Battle of Palmito Ranch -- fought on May 12.
