To the north, an American column led by McDougall came under attack by the Loyalist troops of the Queen's Rangers, and the Guards of the British reserve. After a brutal contest, McDougall's brigade was forced to retreat, having suffered heavy losses. Despite the reversal in fortune, the Continentals were still convinced of a possible victory. The 9th Virginia Regiment of Greene's column launched a determined attack on the British lines as planned, managing to break through and capturing a number of prisoners. However, they were soon surrounded by two arriving British brigades under Cornwallis. Cornwallis then launched a counter-charge, cutting off the Virginians completely, forcing them to surrender. Greene, upon learning of the main army's defeat and withdrawal, realized he stood alone against Howe's entire army, and so withdrew.
