Chatterton's Hill, From the Railway Station
While Washington was inspecting the terrain, seeing where it was best to station his troops, he ran into several light horseman and told him that the British were advancing. Washington rode back to camp to prepare his men. He quickly stationed a couple hundred Continentals and a couple of artillery pieces onto Chatterton Hill, to support the militia. The skirmishers, who had the job of slowing the British advance, retired soon after Washington reinforced Chatterton Hill.
