He could do only what was possible. To stay yonder was impossible. And the scarred veteran of thirty-three years, came back pale and in despair. Lee had struck his last great blow, and it had failed. XVII. THE WRESTLE FOR THE WHITE OAK ROAD. It is unsafe to wound the wild-boar, unless the wound be mortal. To change the figure, Grant had parried the almost mortal thrust of Lee; and now, with the famous hammer lifted and whirled aloft, aimed the final and decisive blow at the crest of his great adversary. On Wednesday, March 29th, the Federal commander commenced the general movement, which had for its object the destruction of Lee’s right wing, and the occupation of the Southside road. Before dawn, the masses of blue infantry began to move westward across the Rowanty, laying down bridges over the watercourses, as the columns passed on; and on the night of the same day, the corps of Humphreys and Warren were near Dinwiddie Court-House with their extreme right guarded, by Sheridan’s cavalry. Such was the work of Wednesday. The great moment had evidently arrived. Lee penetrated at a single glance the whole design of his adversary; collected about fifteen thousand men, nearly half his army, and leaving Longstreet north of the James, and only a skirmish line around Petersburg, marched westward, beyond the Rowanty, to meet the enemy on the White Oak road. On the morning of the 30th, all was ready for General Grant’s great blow. But the elements were hostile to the Federal side. In the night, a heavy rain had fallen. All day on the 30th, it continued to rain, and military movements were impossible. The two great opponents looked at each other,--lines drawn up for the decisive struggle. On the 31st, Grant was about to open the attack on Lee, when that commander saved him the trouble. The Virginian seemed resolved to die in harness, and advancing. The corps of Humphreys and Warren had advanced from Dinwiddie Court-House toward the Southside road, and Warren was in sight of the White Oak road, when, suddenly, Lee hurled a column against him, and drove him back. The Confederates followed with wild cheers, endeavoring to turn the enemy’s left, and finish them. But the attempt was in vain. Federal re-enforcements arrived. Lee found his own flank exposed, and fell back doggedly to the White Oak road again, having given the enemy a great scare, but effecting nothing. As he retired, intelligence reached him that Sheridan’s cavalry were advancing upon Five Forks. That position was the key of the whole surrounding country. If Sheridan seized and occupied this great _carrefour_, Lee’s right was turned.
