On the Confederate side, it was confidently expected, after the two days’ fighting, that the next day’s work would consist in vigorously pressing the rear of Grant’s columns on their retreat across the river. For every soldier in the Army of Northern Virginia regarded such retreat as inevitable, and the only difference of opinion among them was as to what General Lee would do next. The general expectation was that he would almost instantly move by his left flank for another invasion of Maryland and Pennsylvania, another threatening of Washington City.
And there was good ground of precedent for these Confederate expectations. Lee had undoubtedly inflicted a severer punishment upon Grant than he had before done upon McClellan, Pope, Burnside, or Hooker, and moreover he had completely baffled Grant’s plan of campaign, thwarting his attempt to turn the Confederate right and plant his army in the Confederate rear near Gordonsville. Four times the Army of Northern Virginia had seen its adversary retreat and assume the defensive after less disastrous defeats than that which the Southerners were confident they had inflicted upon Grant in these two days’ desperate work. Why should they not expect Grant, therefore, to retreat across the river, as all his predecessors had done under like circumstances? And why should not Lee again assume the right to decide where and when and how the struggle should be renewed, as he had done three times before?
The fallacy in all this lay in its failure to recognise Grant’s quality, in its assumption that he was another McClellan, another Pope, another Burnside, another Hooker.
Between him and his predecessors there was this fundamental difference: they set out to force their way to Richmond by strategy and fighting, and when they found themselves outmanœuvred and badly damaged in battle, they gave up their aggressive attempts and contented themselves with operations for the defence of the Federal capital; Grant had set out to conquer or destroy Lee’s army by the use of a vastly superior force whose losses could be instantly made good by reinforcements, while Lee had nowhere any source from which to draw fresh troops, and when Grant found his first attempt baffled and his columns badly damaged in fight, he obstinately remained where he was, sent for reinforcements, and made his preparations to “fight it out on this line if it takes all summer.”
