By some means--probably by reason of the fierce firing on either side--a forest fire now broke out in Hancock's front, and the flames quickly communicated themselves to the log revetments of his fortifications. The heat and the smoke forced the Federals to retreat, fighting as they went against the Confederates who pursued them with fury. Sadly enough, besides the dead there were large numbers of wounded men, both Federal and Confederate, lying among the burning bushes and underbrush of that mile-wide stretch of wilderness over which the flames swept. Here misfortune and sheer accident wantonly added to the necessary horrors of war another horror not contemplated or intended by either commander although that, like all other risks of battle, is included in the contract which the soldier makes with his country. These men, wounded and helpless as they lay amid the flames that circled and enwrapped them, must have realized as nobody unaccustomed to the horrors of war can, the truth of Sherman's statement that "war is all hell." Night ended the struggle, and the men on both sides retired to their entrenchments to await the events of the morrow. On neither side was there the least suggestion of demoralization or of shrinking from the work that was yet to be done. On neither side were there skulkers in the rear as there had been at Manassas, at Shiloh and at nearly every other great battle of an earlier time. The volunteers who composed the armies of the Potomac and Northern Virginia were real soldiers now, inured to war, and desperate in their determination to do its work with out faltering or failure. This fact--this change in the temper and morale of the men on either side--had greatly simplified the tasks set for Grant and Lee to solve. They knew their men. They knew that those men would stand against anything, endure slaughter without flinching, hardship without complaining, and make desperate endeavor without shrinking. The two armies had become what they had not been earlier in the contest, perfect instruments of war, that could be relied upon as confidently as the machinist relies upon his engine scheduled to make so many revolutions per minute at a given rate of horse power, and with the precision of science itself. It will be remembered that as Jefferson Davis approached the battlefield of Manassas, where the Confederates had won a conspicuous victory, the multitude of panic-stricken fugitives through whom he passed was such as to convince him that Beauregard had been disastrously defeated. It will be remembered that at Shiloh when Grant made his way to the front he was appalled by the presence under shelter of the river banks of a multitude of fugitives, demoralized and panic-stricken, who ought to have been at the front lying on their bellies and firing at the enemy. Nothing of the kind occurred on either side at the Wilderness. The war school had perfectly educated its pupils.
