At the rear of the camp, wagons were parked while Picket Post #3 guarded the right flank near the approximate location marked by the steeple of the Baptist Church. Lieutenant Samuel Brady was with Picket #3 and, when the British came nearly upon them before the sentinel fired, he ran, had his blanket pinned to a fence rail by a musket blow, tore free, shot dead a pursuing horseman who ordered him to stop, and reached a small swamp where by morning he discovered fifty five men and took command of them back to camp. Picket Post #4, three-quarters of a mile farther down the Lancaster Road at Old Lincoln Highway and Langford Avenue, was the first post attacked. It was manned by a lieutenant, sergeant, corporal, and sixteen privates facing a British advance guard of dragoons, riflemen, and light infantry. A British officer recalled that the picket fired on them at fifteen yards without effect and was instantly dispatched by the riflemen's swords. Nearly half of the pickets were killed or wounded, while the others fell back to camp, and in the confusion Smallwood stopped his own men from firing on their friends by leaping from his horse and calling out until they recognized his voice.
