Sir: Instead of proceeding to Coryell's Ferry, which I imagine is your intended Route, I desire you will march down, as far as Trenton, and there wait my orders before you cross the River. The moment you receive this, dispatch an Officer to me, to inform me where you are, when you will be at Trenton, and by what Road you will march that I may send orders to meet you. I am etc.
P.S. If this should reach you between Flemingtown and Coryells Ferry, You are not to march towards Trenton, but cross at Coryell's as first intended. (19)
