On Greene’s right, Weedon’s Continentals held their fire until the left front and flank of the Agnew’s line were almost directly in front of them. When they opened fire, his four Virginia regiments, together with 21-year-old Col. Walter Stewart’s Pennsylvania State Regiment, caught Agnew’s British regiments in an open field. It was obvious almost immediately that Agnew’s command was in trouble. When the lead began flying through the ranks of his left regiment, the 33rd Foot stopped advancing, wheeled to the left to face the enemy hidden in the woods, and returned fire. The five companies of the light infantry on the 33rd’s right seem to have followed suit. The 46th and 64th, however, continued tramping deeper into a heavy fire that was at this stage primarily still coming from their front. The 37th Foot on the far right of the line kept marching west, its front bisected by the Wilmington Road. Although the brigade elements seem to have maintained a relatively cohesive line, the center of Agnew’s front bowed toward Greene’s line, mimicking the patriot front though on a smaller scale. Agnew’s advance, however, had captured—at least temporarily—part of the higher elevation Ewald had pointed out, and in so doing protected the 2nd Grenadier Battalion’s exposed flank. And Greene’s men were about to extract a high price for doing so.29
