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.
Daniel Sickles
The Battle of Gettysburg was the occasion of the most famous incident and the effective end of Sickles' military career. On July 2, 1863, Army of the Potomac commander Maj. Gen. George G. Meade ordered Sickles' corps to take up defensive positions on the southern end of Cemetery Ridge, anchored in the north to the II Corps and to the south, the hill known as Little Round Top. Sickles was unhappy to see the "Peach Orchard," a slightly higher terrain feature, to his front. He violated orders by marching his corps almost a mile in front of Cemetery Ridge. This had two effects: it greatly diluted the concentrated defensive posture of his corps by stretching it too thin, and it created a salient that could be bombarded and attacked from multiple sides. About this time (3 p.m.), Meade called a meeting of his corps commanders. Sickles did not appear. An aide to Brig. Gen. Gouverneur K. Warren soon reported the situation. Meade and Warren rode to Sickles' position, where Meade demanded an explanation from the general. Meade refused Sickles' offer to withdraw because he realized it was too late and the Confederates would soon attack, putting a retreating force in even greater peril.
