I think you have it a little messed around. The Long Island battle was in Aug 27 1776. Trenton (river crossing) was Dec 26, 1776. In short order was the battle at Princeton.
Basically the rebels went into winter quarters for the awful Morristown encampment. Brits retreated to New Brunswick and maintained control of NYC and area.
When I wrote "In addition to the Delaware River crossing and Hessian camp attack, it covers the British invasion of New York and subsequent Battle of Brooklyn (aka, Battle of Long Island)", I didn't mean it to be in chronological order. Perhaps I should have worded it differently. I'm fully aware of the major RW events that took place here in NYC. :)
Check out those videos if you get a chance, especially the first one which I linked to in post 2.
Well, this part was clearly in correct chronological order: “British invasion of New York and subsequent Battle of Brooklyn (aka, Battle of Long Island)”
I listed the Delaware River Crossing first because that is the subject of the thread. I added the other things just to say what else is in the video.
