Today in History, July 4, 1863:
Confederate General John C. Pemberton surrenders Vicksburg, Mississippi to Union General Ulysses S. Grant. Pemberton had sent a note asking for terms on the 3rd, and initially Grant gave is usual “unconditional surrender” response. He then thought about what he would do with 30,000 starving Southern troops, who he had lay siege to since May 18th, and granted them parole, accepting the surrender on the 4th.
The capture of Vicksburg effectively cut off of the Confederate states west of the Mississippi (and their supplies) from the South. Grant’s parole of the rebels would come back to bite him, as the Confederacy did not recognize it’s terms and many of them fought again…which came back to bite the Confederacy because as a result the Union stopped trading prisoners.
The South knew the consequences of the loss of Vicksburg. It would be many, many years before Independence Day was celebrated in Vicksburg again.
