Dru had a two-fold purpose in preparing at three in the morning. First, he wanted to take no chances upon General Newton’s time of attack. His information as to six o’clock he thought reliable, but it might have been given out to deceive him and a much earlier engagement might be contemplated.
His other reason was that he intended to flank Newton on both wings.
It was his purpose to send, under cover of night, one hundred and twenty-five thousand men to the right of Newton and one hundred and twenty-five thousand to his left, and have them conceal themselves behind wooded hills until noon, and then to drive in on him from both sides.
He was confident that with two hundred and fifty thousand determined men, protected by the fortifications he had been able to erect, and with the ground of his own choosing, which had a considerable elevation over the valley through which Newton would have to march, he could hold his position until noon. He did not count upon actual fighting before eight o’clock, or perhaps not before nine.
Dru did not attempt to rest, but continued through the night to instruct his staff officers, and to arrange, as far as he could, for each contingency. Before two o’clock, he was satisfied with the situation and felt assured of victory.
He was pleased to see the early morning hours develop a fog, for this would cover the march of his left and right wings, and they would not have to make so wide a detour in order that their movements might be concealed. It would also delay, he thought, Newton’s attack.
His army was up and alert at three, and by four o’clock those that were to hold the center were in position, though he had them lie down again on their arms, so that they might get every moment of rest. Three o’clock saw the troops that were to flank the enemy already on the march.
At six-thirty his outposts reported Newton’s army moving, but it was nine o’clock before they came within touch of his troops.
In the meantime, his men were resting, and he had food served them again as late as seven o’clock.
Newton attacked the center viciously at first, but making no headway and seeing that his men were being terribly decimated, he made a detour to the right, and, with cavalry, infantry and artillery, he drove Dru’s troops in from the position which they were holding.
