Wayne announced that he would give prize bounties to the first men who entered the works, and to anyone else who distinguished himself in the action. After a morning muster, on July 15, 1779, the Corps of Light Infantry marched from Sandy Beach north of Fort Montgomery beginning at noon. Any civilians met along the route of march were to be taken into custody to prevent them from warning the British. The column, often forced to march single file over rough terrain and roads hardly more than paths, took a circuitous route west through Queensboro to the west and over Dunderberg Mountain to avoid detection by the British. The Corps began arriving at 8 p.m. at the Springsteel farm, a mile and a half (2 km) west of the fortifications, and by 10 p.m. had been formed in the attack columns. The men were given a rum ration and their orders. They were also given pieces of white paper to pin to their hats in order to help them tell each other from the British in the darkness. The columns then moved out at 11:30 p.m. to their jump-off points, diverging immediately, to begin the assault at midnight. These attack columns were led by groups of volunteer soldiers nicknamed the “forlorn hope” who were responsible for breaking holes in enemy defenses and along with their weapons, were armed with axes and picks. Bad weather that night aided the Continentals. Cloud cover cut off moonlight and high winds forced the British ships in Haverstraw Bay to leave their posts off Stony Point and move downriver. At midnight, as scheduled, the attack began with the columns crossing the swampy flanks of the point. The southern column unexpectedly found its approach inundated in two to four feet of water and required thirty minutes to wade to the first line of abatis, during which it and Murfree's demonstration force were spotted by British sentries and fired upon. Under fire Wayne's column succeeded in getting inside the British first line of defenses. Wayne himself was struck in the head by a spent musket ball and fell to the ground, leaving Col. Febiger to take over command of Wayne's column. Meanwhile, Butler's column had succeeded in cutting its way through the abatis, sustaining the only loss of life on the American side while doing so. The two columns penetrated the British line almost simultaneously and seized the summit when six companies of the 17th Regiment of Foot took positions opposite the diversionary attack and were cut off.
