These lines were the regiments of Buell's leading division, which having moved from Savannah through a country presenting nothing but interminable swamps and pathless "bottom lands," with rank overgrowths of jungle, was arriving at the scene of action breathless, footsore and faint with hunger. It had been a terrible race; some regiments had lost a third of their number from fatigue, the men dropping from the ranks as if shot, and left to recover or die at their leisure. Nor was the scene to which they had been invited likely to inspire the moral confidence that medicines physical fatigue. True, the air was full of thunder and the earth was trembling beneath their feet; and if there is truth in the theory of the conversion of force, these men were storing up energy from every shock that burst its waves upon their bodies. Perhaps this theory may better than another explain the tremendous endurance of men in battle. But the eyes reported only matter for despair.
