Washington had acted decisively to form a strong defensive position anchored on the right above the bridge on the Englishtown road and extending in a gentle curve up the slope of Perrine's Hill. When Lee joined it, Washington sent him with two battalions of Maxwell's New Jersey Brigade, around half of Scott's detachment and some other units of the former vanguard to form a reserve at Englishtown. The rest of the vanguard, which included the other half of Scott's detachment and most of Wayne's, remained with Washington. The infantry battle gave way to a two-hour artillery duel across the of no-man's land on either side of the brook, in which both sides suffered more casualties due to heat exhaustion than they did from enemy cannon.
