12- The Invasion of the North
Following Davis’s approval, the armies of the Confederacy began to move. Magruder vanished across the Blue Ridge Mountains, and Longstreet moved out from Richmond. Longstreet met McDowell at the North Anna River, and in the month that followed Longstreet was outmaneuvered and outnumbered, forced to inch back to Richmond. Yet McDowell stayed the killing blow when scouts reported to him that Magruder’s force was gone. He had no idea if Magruder had joined with Longstreet or if he had joined Johnston in the Valley. Instead of the ANV joining McDowell’s ACV as planned, the ANV remained at Centreville.
Magruder had led his army on a night march across the mountains to Front Royal, confusing Union spies when his rearguard marched in circles around the same area, giving the impression he was still near Culpeper and possibly being reinforced. That gave Magruder only two weeks, until the spies realized it was a ruse. Johnston and Lightning Jackson made a quick feint towards Harpers Ferry, drawing McClellan there, then linked up with Magruder and crossed the Potomac at Williamsport. Chambersburg was reached by the beginning of August, and the Confederates enjoyed an early harvest in the untouched North. Johnston maintained the momentum and within a week was at the Susquehanna River at Camp Hill. McClellan launched his pursuit, yet was cautionary, as it was reported to him that the enemy outnumbered him. McClellan arrived at Gettysburg just days after hearing about the sacking of York.
At this point, there was disagreement in the Confederate leadership. Johnston wanted to fight the defensive battle and get out of the North while they still could. Magruder wanted to go further, possibly sacking Baltimore, Harrisburg, Lancaster, or even Philadelphia, maximising the value of the invasion. Lightning Jackson wanted to smash McClellan’s army, to prevent him from linking up with other Union forces. With McClellan slowly closing in, what would the Confederates choose to do?
