futher events
By the end of June, over half of Pemberton's men were ill or in the hospital. Feeling that Vicksburg was doomed, Pemberton contacted Grant on July 3 and requested terms for surrender. After initially demanding an unconditional surrender, Grant relented and allowed the Confederate troops to be paroled. The following day, the 4th of July, Pemberton turned the town over to Grant, giving the Union control of the Mississippi River. Combined with the victory at Gettysburg the day before, the fall of Vicksburg signaled the ascendancy of the Union and the decline of the Confederacy.
