To keep the ranks closed and aligned in any tolerable fighting shape while struggling through that mile of tangled forest and broken ground, was a task of terrible difficulty. Plunging through thickets, leaping over fallen trees, a continuous foliage overhead, and the fallen leaves of many seasons under foot, the air full of the damp, mouldering smell of virgin forest, the brigade moved forward with no sound but that of its own tramplings. It is peculiar of the American attack that it is almost always made in line, and always without music. The men expected to meet the enemy at every hillock, but they advanced rapidly, and laughed at each other's slippings and tumbles. Every body was breathless with climbing over obstacles or running around them. The officers were beginning to swear at the broken ranks and unsteady pace. The Lieutenant-Colonel, perceiving that the regiment was diverging from its comrades, and fearing the consequences of a gap in case the enemy should suddenly open fire, rode repeatedly up and down the line, yelling, "Guide right! Close up to the right!" Suddenly, to the amazement of every one, the brigade came upon bivouacs of Union regiments quietly engaged in distributing rations and preparing breakfast. "What are you doing up here?" asked a Major of Colburne. "We are going to attack. Don't you take part in it?" "I suppose so. I don't know. We have received no orders." Through this scene of tardiness, the result perhaps of one of those blunders which are known in military as well as in all other human operations, Weitzel's division steadily advanced, much wondering if it was to storm Port Hudson alone. The ground soon proved so difficult that the Tenth, unable to move in line of battle, filed into a faintly marked forest road and pushed forward by the flank in the ordinary column of march. The battle had already commenced, although Colburne could see nothing of it, and could hear nothing but a dull _pum-pum-pum_ of cannon. He passed rude rifle-pits made of earth and large branches, which had been carried only a few minutes previous by the confused rush of the leading brigade. Away to the right, but not near enough to be heard above the roar of artillery, there was a wild, scattering musketry of broken lines, fighting and scrambling along as they best could over thicketed knolls, and through rugged gullies, on the track of the retiring Alabamians and Arkansans. It was the blindest and most perplexing forest labyrinth conceivable; it was impossible to tell whither you were going, or whether you would stumble on friends or enemies; the regiments were split into little squads from which all order had disappeared, but which nevertheless advanced.
