Early in the war, Federal naval strategy focused on control of the Mississippi, and, by the spring of 1862, key port cities were captured by Federal forces, giving them control of the river. With the Southern states divided between East and West, the Confederate government was forced to devise special measures to maintain transportation and communication along the trans-Mississippi routes. Surreptitious traffic across the river was carried on by private and government couriers, and the post office was authorized to appoint agents to ensure that the mail lines remained open. In April 1863 the Confederate Congress authorized a "preferred mail" across the Mississippi River and established a 50¢ rate per half-ounce. The act was revised to create an "express mail" without a fixed rate of postage, but instead limited to no more than a dollar per half ounce. By October 1863, Postmaster General Reagan secured a contract to have mail carried across the Mississippi at the rate of 40¢ per half ounce. Meridian and Brandon, Mississippi, were chosen as the eastern terminal points. Shreveport and Alexandria, Louisiana, were chosen as the western terminal points.One of the most Important Trans-Mississippi covers in existence!
