In rather more than half an hour after Sullivan had been engaged, the left wing, having formed the line, came also into action; and, attacking the light infantry posted in front of the British right wing, soon drove it from its ground. While rapidly pursuing the flying enemy, Woodford's brigade,[70] which was on the right of this wing, was arrested by a heavy fire from Chew's house, directed against its right flank. The inefficiency of musketry against troops thus sheltered being instantly perceived, the brigade was drawn off to the left by its commanding officer, and the field-pieces attached to it were ordered up to play on the house, but were too light to be of service. Some time was consumed in this operation, and the advance of the brigade was, of course, retarded. This part of the line was consequently broken, and the two brigades composing the division of Stephen were not only separated from each other, but from the other division which was led by General Greene in person. That division, consisting of the brigades of Muhlenberg and Scott, pressing forward with eagerness, encountered and broke a part of the British right wing, entered the village, and made a considerable number of prisoners. [Footnote 70: The author was in this brigade, and describes this part of the action from his own observation.] Thus far the prospect was flattering. The attack had been made with great spirit; several brigades had entered the town; and such an impression had been made on the British army as to justify the expectation that its wings might be separated from each other, and a complete victory be obtained. Had the American troops possessed the advantages given by experience; had every division of the army performed with precision the part allotted to it, there is yet reason to believe that the hopes inspired by this favourable commencement would not have been disappointed. But the face of the country, and the darkness of the morning produced by a fog of uncommon density, co-operating with the want of discipline in the army, and the derangements of the corps from the incidents at Chew's house, blasted their flattering appearances, and defeated the enterprise.
