Estimate  $500 - 750. This is a wonderful Trans-Mississippi cover is used after the fall of Vicksburg, Mississippi, on July 4, 1863, but before the Post Office Department's Trans-Mississippi Express Service went into effect on October 20, 1863. In early July 1863, the 4th Texas Regiment lost more than 25% of the 415 effectives that fought at the Battle of Gettysburg. Private Erskine was one of the lucky soldiers in the regiment to survive the great battle. This letter, which was written a little over one month after the bloody engagement, was sent to the care of the Texas (Supply) Depot at Richmond for determining how to get it to Texas. Since at this time no soldier was returning to Texas that could hand-carry the correspondence, the Texas (Supply) Depot deposited the properly endorsed soldier's letter at the Richmond Post Office where it sent on to Texas via the Confederate postal system. $0 (Image)
