Gettysburg: A Novel of the Civil War
The story takes place in 1863 when Robert E. Lee and the Army of Northern Virginia are victorious at the Battle of Gettysburg instead of the United States. (Instead of attacking the Union line on July 2, 1863, Lee conducts a broad turning movement and forces the Army of the Potomac to attack him in a favorable position.) Gettysburg becomes something of a footnote in the main battle, which takes place at Union Mills in Maryland. The defeat at Union Mills is a grave setback to the United States, but it by no means spells the end of the war or determines its outcome, and the United States still has a lot of fight in it.
Gettysburg Campaign
The Gettysburg Campaign was a military invasion of Pennsylvania by the main Confederate army under General Robert E. Lee in summer 1863. The Union won a decisive victory at Gettysburg July 1–3, with heavy casualties on both sides. Lee managed to escape back to Virginia with most of his army. It was a turning point in the American Civil War, with Lee increasingly pushed back toward Richmond until his surrender in April 1865. After his victory in the Battle of Chancellorsville, Lee's Army of Northern Virginia moved north for a massive raid designed to obtain desperately needed supplies, to undermine civilian morale in the North, and to encourage anti-war elements. The Union Army of the Potomac was commanded by Maj. Gen. Joseph Hooker and then (from June 28) by Maj. Gen. George G. Meade.
