On January 17-18, Brig. Gen. William Heath started 3 divisions toward Kings Bridge so as to converge simultaneously on the British outposts at dawn on January 18. All together, Heath had a total of almost 6,000 troops under his command. Initially, the plan went smoothly with all 3 columns arrived on schedule. They overran the British outposts at Valentine's Hill, Van Courtland's, Williams', and the Negro Fort.
Next, they closed in on Fort Independence. Fort Independence was located in the Valentine's Hill area just north of Spuyten Duyvil and Kings Bridge on the approach to Manhatten. The fort was manned by about 2,000 German Hessians. Heath summoned the German commander, who was taken by surprise, to surrender the fort within 20 minutes. The commander rejected Heath's demand to surrender and responded by unleashing a cannonade against the Americans. This surprised Heath because he thought that the fort did not have any artillery. Heath ordered his own cannonade on the fort and started to manuever his troops.
On January 19, Heath ordered an envelopement across the frozen creek, slated to start the next day. The reason for this was to cut off the battalion at Kings Bridge.
On January 20, Heath cancelled his order because the warm weather made trying to cross over the ice on the creek too dangerous. For the next several days, there was minor skirmishing all around the area.
On January 25, a party of British and Tory soldiers marched in the direction of Delancey's Mills. Once there, they routed Heath's troops in that sector. Emboldened by their success, the party then headed towards the Valentine's Hill sector. Here, they cleared the Americans in this sector and the Negro Fort sector. They then pushed on to scatter the other Americans before them.
On January 29, an approaching blizzard convinced Heath and the other commanders that they should withdraw. . Heath withdrew his forces, returning to Spuyten Duyvil. This retreat elicited the scorn of the Hessians.
