Fort Arnold, later renamed Fort Clinton following Benedict Arnold’s treason, was the main fortification at West Point. Situated at the tip of the Plain overlooking the Hudson River, it contained 12 cannon and 11 mortars and, with support from four riverline batteries, dominated the sharp bend in the Hudson River and protected the Great Chain. More than 620 soldiers, excluding artillerymen, were needed to man the fort.
