After the mortal shooting of Ross, the British under Colonel Arthur Brooke advanced through the Bouldin family farm to attack the American line anchored at the junction of North Point Road and Trappe Road. General Stricker's line consisted of the 27th, 5th, 39th and 51st regiments of Maryland Militia, supplemented with a company from Hagerstown and several companies of troops from Pennsylvania. The Battle of North Point lasted for several hours during the afternoon. Brooke sent his 4th Regiment of Foot in a flanking maneuver to unsettle the American left, which led to Stricker's 51st regiment and elements of the 39th regiment to retreat in some disorder. The remainder of the Americans traded volleys with the invaders until they eventually retreated in good order when their ammunition began to become low.
