The widely-separated Union triumphs at Vicksburg (on the Mississippi) and Gettysburg (Pennsylvania) were announced on the same day, July 4th 1863, and led to Grant's relief of the Army of the Cumberland at Chattanooga, saving it from starvation and capture. Before long, he would be promoted General-in-Chief of the Union armies.

Confederate General John C. Pemberton was born in Pennsylvania but joined the Confederacy when his adopted state of Virginia seceded from the Union. Probably the most significant part of his role in the US Civil War, was that he was forced to surrender Vicksburg after the successful Union siege which lasted six weeks.
