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.
John F. Chase
Two months after earning the Medal of Honor at Chancellorsville, Chase participated in the Battle of Gettysburg. The 5th Maine Battery was a part of General John F. Reynolds' I Corps and fought at Seminary Hill on the first day of the battle, July 1, 1863. As the Confederates advanced, the corps fell back past the town of Gettysburg, with Chase's battery taking up a position on a knoll between Culp's Hill and Cemetery Hill. On the battle's third day, July 3, the Confederates launched an assault on Cemetery Hill. Chase's battery fired with devastating effect on the attacking infantry, and in response, three or four Confederate batteries began targeting the 5th Maine's position.
