Lafayette led 350 men toward the British position. He carefully scouted the British camp, at times personally coming within firing range of British sentries. He then led his men in a surprise attack on a forward pickett of jaegers. The 400 Hessians were caught completely unprepared, and began a disorganized fighting retreat toward the main British camp, with Lafayette and his men giving chase. Cornwallis sent some grenadiers to provide covering fire as the Germans retreated, and Lafayette withdrew under cover of darkness, returning to Greene.
