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.
Battle of Gettysburg
Gettysburg became a postbellum focus of the "Lost Cause", a movement by writers such as Edward A. Pollard and Jubal Early to explain the reasons for the Confederate defeat in the war. A fundamental premise of their argument was that the South was doomed because of the overwhelming advantage in manpower and industrial might possessed by the North. However, they claim it also suffered because Robert E. Lee, who up until this time had been almost invincible, was betrayed by the failures of some of his key subordinates at Gettysburg: Ewell, for failing to seize Cemetery Hill on July 1; Stuart, for depriving the army of cavalry intelligence for a key part of the campaign; and especially Longstreet, for failing to attack on July 2 as early and as forcefully as Lee had originally intended. In this view, Gettysburg was seen as a great lost opportunity, in which a decisive victory by Lee could have meant the end of the war in the Confederacy's favor.
