Northern Virginia Campaign - Plans and Initial Movements

Plans and Initial Movements

Pope's mission was to fulfill a few objectives: protect Washington and the Shenandoah Valley, and draw Confederate forces away from McClellan by moving in the direction of Gordonsville. Pope started on the latter by dispatching cavalry to break the Virginia Central Railroad connecting Gordonsville, Charlottesville, and Lynchburg. The cavalry under Hatch got off to a slow start and found that Stonewall Jackson had already occupied Gordonsville on July 19 with over 14,000 men. (After a subsequent second failure to cut the railroad on July 22, Pope removed Hatch from his cavalry command and reassigned him to command an infantry brigade in Brig. Gen. Rufus King's division of the III Corps.)

Pope had an additional, broader objective, encouraged by Abraham Lincoln. For the first time, the Union intended to pressure the civilian population of the Confederacy by bringing some of the hardships of war directly to them. Pope issued three general orders on the subject to his army. General Order No. 5 directed the army to "subsist upon the country," reimbursing farmers with vouchers that were payable after the war only to "loyal citizens of the United States." To some soldiers, this became an informal license to pillage and steal. General Orders 7 and 11 dealt with persistent problems of Confederate guerrillas operating in the Union rear. Pope ordered that any house from which gunfire was aimed at Union troops be burned and the occupants treated as prisoners of war. Union officers were directed to "arrest all disloyal male citizens within their lines or within their reach." These orders were substantially different from the war philosophy of Pope's colleague McClellan, which undoubtedly caused some of the animosity between the two men during the campaign. Confederate authorities were outraged and Robert E. Lee labeled Pope a "miscreant" and added that he "ought to be suppressed."

Based on his experiences in the Seven Days, Lee concluded that McClellan would not attack, and he could thus move most of his army away from Richmond. This allowed him to relocate Jackson to Gordonsville to block Pope and protect the Virginia Central. Lee had larger plans in mind. Since the Union Army was split between McClellan and Pope and they were widely separated, Lee saw an opportunity to destroy Pope before returning his attention to McClellan.

On July 26, Lee met with cavalry legend and partisan fighter Capt. John S. Mosby, who had just been exchanged as a prisoner of war. Coming through the Hampton Roads area in Union custody, Mosby observed significant naval transport activity and deduced that Maj. Gen. Ambrose Burnside's troops, who had fought in North Carolina, were being shipped to reinforce Pope. Wanting to take immediate action before those troops were in position, the next day Lee committed Maj. Gen. A.P. Hill to join Jackson with 12,000 men, while distracting McClellan with artillery bombardments and diversionary movements. McClellan advanced a force from Harrison's Landing to Malvern Hill, and Lee moved south to meet the threat, but McClellan eventually withdrew his advance. Still convinced that he was heavily outnumbered, he sent messages to Washington that he would need at least 50,000 more men before he could attempt another attack on Richmond. On August 3, General-in-Chief Henry W. Halleck directed McClellan to begin his final withdrawal from the Peninsula and to return to Northern Virginia to support Pope. McClellan protested and did not begin his redeployment until August 14. The Army of the Potomac returned to Washington except for a division of the IV Corps, which was left on the Virginia Peninsula.
