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.
Winfield Scott Hancock
Hancock's most famous service was as a new corps commander at the Battle of Gettysburg, July 1 to 3, 1863. After his friend, Maj. Gen. John F. Reynolds, was killed early on July 1, Maj. Gen. George G. Meade, the new commander of the Army of the Potomac, sent Hancock ahead to take command of the units on the field and assess the situation. Hancock thus was in temporary command of the "left wing" of the army, consisting of the I, II, III, and XI Corps. This demonstrated Meade's high confidence in him, because Hancock was not the most senior Union officer at Gettysburg at the time. Hancock and the more senior XI Corps commander, Maj. Gen. Oliver O. Howard, argued briefly about this command arrangement, but Hancock prevailed and he organized the Union defenses on Cemetery Hill as more numerous Confederate forces drove the I and XI Corps back through the town. He had the authority from Meade to withdraw the forces, so he was responsible for the decision to stand and fight at Gettysburg. At the conclusion of the day's action, Maj. Gen. Henry Warner Slocum arrived on the field and assumed command until Gen. Meade arrived after midnight.
