The Post Office During the Civil War

Communication was vital during the Civil War and the post office was the main source for relaying information. The telegraph service was not as dependable as both sides took turns cutting the wires and destroying the service. Mail did not always get through as easily and quickly as one would think.

The envelope played a big part in the Civil War—far more than a cover for a letter. The printing companies from both sides saw the opportunity to utilize the space on an envelope to spread their propaganda.
