But at last the Confederates--though checked and roughly handled--converged under Lee's own eye; and an inferno of shot and shell loosened and shook the steadfast Federal defense. Lee and Jackson, though far apart, gave the word for the final charge at almost the same moment. As Jackson's army suddenly burst into view and swept forward to the assault the joyful news was shouted down the ranks: "The Valley men are here!" Thereupon Lee's men took up the double-quick with "Stonewall Jackson! Jackson! Jackson!" as their battle cry. The Federals fought right valiantly till their key-point suddenly gave way, smashed in by weight of numbers; for Lee had brought into action half as many again as Porter had, even with his reinforcements. On the gallantly defended hill the long blue lines rocked, reeled, and broke to right and left all but the steadfast regulars, whose infantry fell back in perfect order, whose cavalry made a desperate though futile attempt to stay the rout by charging one against twenty, and whose four magnificent batteries, splendidly served to the very last round, retired unbroken with the loss of only two guns. Then the Confederate colors waved in triumph on the hard-won crest against the crimson of the setting sun. The victorious Confederates spent the twenty-eighth 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.
