The next day, September 16, there was further fighting when a clash of outposts escalated into a running battle below Washington's lines on Harlem Heights. After several hours exchange of musketry, the forces engaged returned to their start lines, and the position of the two armies on Manhattan remained relatively unchanged for the next two months. Having held their own against picked British troops, the American army received a much needed boost to their morale after the debâcle of the previous day, while the British acquired a renewed respect for the American ability to stand and fight.
