What was the purpose of the battle of Fort Lee? plz help asap​

They were built to cover a line of obstructions across the Hudson River to bar the movement of British ships. Also, they intended to frustrate the British war plan: "Control the Hudson River with the Royal Navy to cut the colonies in two, then suppress the rebellion, first in New England and elsewhere if necessary."

I’m not sure if that’s the purpose of the BATTLE but it’s the purpose of the fort :\
