The several divisions of the British army had been separated from each other by extending themselves to the right and left in order to encounter the distinct corps which threatened their flanks; and by advancing in regiments at different times, as the different parts of the second line had given way. The thickness of the wood increased the difficulty of restoring order. They pressed forward with great eagerness, but with a considerable degree of irregularity. Greene, in this state of the action, entertained the most sanguine hopes of a complete victory. His continental troops were fresh, in perfect order, and upon the point of engaging an enemy, broken into distinct parts, and probably supposing the severity of the action to be over. This fair prospect was blasted by the misconduct of a single corps. The second regiment of Maryland was posted at some distance from the first, in open ground; its left forming almost a right angle with the line, so as to present a front to any corps which might attack on that flank. The British in advancing, inclined to the right; and the second battalion of guards entered the open ground immediately after the retreat of Stevens, and rushed on the second regiment of Maryland while the first was engaged with Webster. Without waiting to receive the charge, that regiment broke in confusion. By pursuing them, the guards were thrown into the rear of the first regiment, from which they were concealed by the unevenness of the ground, and by a skirt of wood. Greene was himself on the left, and witnessed the misfortune without being able to remedy it. His militia being entirely routed, the flight of one-fourth of his continental troops would most probably decide the fate of the day. Unwilling to risk his remaining three regiments, only one of which could be safely relied on, without a man to cover their retreat should the event prove unfortunate, he ordered Colonel Greene of Virginia to withdraw his regiment from the line, and to take a position in the rear, for the purpose of affording a rallying point, and of covering the retreat of the two regiments which still continued in the field. The guards were soon called from the pursuit of the second Maryland regiment, and led by Lieutenant Colonel Stuart against the first. About this time Webster, finding himself overpowered by the first Maryland regiment, then commanded by Colonel Gunby, and by Kirkwood's company and the remaining regiment of Virginia, with whom he was engaged at the same time, had in a great measure withdrawn from the action, and retired across a ravine into an adjoining wood. This critical respite enabled Gunby to provide for the danger in his rear. Facing about, he met the guards, and a very animated fire took place on both sides, during which the Americans continued to advance.
