The victorious Confederates spent the twentyeighth and twenty-ninth in finding the way to McClellan's new base. His absolute control of all the waterways had enabled him to change his base from White House on the Pamunkey to Harrison's Landing on the James. When the Confederates discovered his line of retreat by the Quaker Road they pressed in to cut it. On the thirtieth there was severe fighting in White Oak Swamp and on Frayser's Farm. But the Federals passed through, and made a fine stand on Malvern Hill next day. Finally, when they turned at bay on the Evelington Heights, which covered Harrison's Landing, they convinced their pursuers that it would be fatal to attack again;for now Northern sea-power was visibly present in flotillas of gunboats, which made the flanks as hopelessly strong as the front.
McClellan therefore remained safely behind his entrenchments, with the navy in support. He had to his own credit the strategic success of having foiled Lee by a clever change of base; and to the credit of his army stood some first-rate fighting besides some tactical success, especially at Malvern Hill. Nevertheless the second invasion of Virginia was plainly a failure; though by no means a glaring disaster, like the first invasion at Bull Run.
McClellan, again reinforced, still professed his readiness to take Richmond under conditions that suited himself. But the most promising Northern force now seemed to be Pope's Army of Virginia, coming down from the line of the Potomac, forty-seven thousand strong, composed of excellent material, and heralded by proclamations which even McClellan could never excel. John Pope, Halleck's hero of Island Number Ten, came from the West to show the East how to fight. "I presume that I have been called here to lead you against the enemy, and that speedily. I hear constantly of taking strong positions and holding them--of lines of retreat and bases of supplies. Let us discard such ideas. Let us study the probable line of retreat of our opponents, and leave our own to take care of themselves." His Army of Virginia contained Fremont's (now Sigel's) corps, as well as those of Banks and McDowell--all experts in the art of "chasing Jackson."Jackson was soon ready to be chased again. The Confederate strength had been reduced by the Seven Days and not made good by reinforcement; so Lee could spare Jackson only twenty-four thousand men with whom to meet the almost double numbers under Pope. But Jackson's men had the better morale, not only on account of their previous service but because of their rage to beat Pope, who, unlike other Northerners, was enforcing the harshest rules of war. His lieutenant, General von Steinwehr, went further, not only seizing prominent civilians as hostages (to be shot whenever he chose to draw his own distinctions between Confederate soldiers and guerillas) but giving his German subordinates a liberty that some of them knew well how to turn into license. This, of course, was most exceptional; for nearly all Northerners made war like gentlemen. Unhappily, those who did not were bad enough and numerous enough to infuriate the South.
Halleck, who had now become chief military adviser to the Union Government, was as cautious as McClellan and had so little discernment that he thought Pope a better general than Grant.
Lincoln, Stanton, and Halleck put their heads together; and an order soon followed which had the effect of relieving the pressure on Richmond and giving the initiative to Lee. Halleck ordered McClellan to withdraw from Harrison's Landing, take his Army of the Potomac round by sea to Aquia Creek, and join Pope on the Rappahannock--an operation requiring the whole month of August to complete.
Lee lost no time. His first move was to get Pope's advanced troops defeated by Jackson, who brought more than double numbers against Banks at Cedar Run on the ninth of August. The Federals fought magnificently, nine against twenty thousand men. After the battle Jackson marched across the Rapidan, and Halleck wisely forbade Pope from following him, even though the first of Burnside's men (now the advanced guard of McClellan's army) had arrived at Aquia and were marching overland to Pope. Then followed some anxious days at Federal Headquarters. Jackson vanished; and Pope's cavalry, numerous as it was, wore itself out trying to find the clue. MeClellan was still busy moving his men from Harrison's Landing to Fortress Monroe, whence detachments kept sailing to Aquia. What would Lee do now?
On the thirteenth he began entraining Longstreet's troops for Gordonsville. On the fifteenth he conferred with his generals.
