Nevertheless the passage of that ravine was not quite impossible to a determined foe; more difficult tasks have been accomplished by generals of desperate courage commanding such an army as that under Beauregard had proved itself to be during that unflinching day of slaughter. It was a critical moment of the war--we may almost say it was _the_ critical moment of the war. If Beauregard could have forced that ravine he must have driven his adversary into the river or compelled the surrender of the Federal army with its complete destruction as the only alternative. On the other hand, if he failed to force the ravine that night it would be forever too late. For Buell's whole army was now within call and it was certain that on the following day, if Grant were not now destroyed, there would be a Federal force on the Confederate side of the river with which Beauregard could not reasonably hope to cope successfully. It would perhaps be unjust to say that at this supreme crisis Beauregard faltered and failed. The peril of the attempt was so great and the certainty of slaughter so appalling that the very stoutest heart might well have shrunk from the desperate hazard. Beauregard himself has told us in his official reports, and in Colonel Roman's inspired book, that he was unwilling to order a movement so desperate in its chances and so certain to involve a slaughter of brave men greater than any that has been anywhere recorded in the annals of modern war. He was satisfied with the day's work done and confident of complete victory on the morrow. So sure was he of this that he sent dispatches to Richmond that night announcing a victory of stupendous proportions and painting it in colors so glowing that President Davis was moved to send a congratulatory message to the Congress, and that body passed resolutions of the most enthusiastic kind. During that night Buell's army, itself outnumbering what remained of Beauregard's, was hurrying to reinforce Grant who planned to renew the conflict at dawn with every prospect of reversing the first day's results and wresting victory from what had been so nearly a complete and disastrous defeat. Early on the morning of the seventh of April Grant, reinforced by Buell's men and having now an overmastering superiority of numbers, took the offensive and assailed Beauregard's weakened army with a determination which under the circumstances could mean nothing less than victory. But Beauregard was an obstinate fighter and a skilful one and his men were Americans of the same race and lineage and traditions as those they were meeting in battle. There was terrible fighting, therefore, on that second day, and it was only after a very desperate and a very bloody struggle, hours long in duration, that Grant regained the ground lost on the day before.
