Camp at Tappan Sept. 26 1780
Your Excellencys letter dated at Robinsons House 7 oClock last Evening came to hand 1/4 past three this morning. Before the receipt of which I had put the first Pennsylvania brigade in motion; and put the whole army under Marching orders, in consequence of a letter I received from Col. Hambleton dated at Verplanks Point. As the first brigade had marched, I thought it most advisable to let the Second follow it, rather than break a division in the left Wing. The Troops marched with out their baggage which is to follow them this morning. The rest of the Army is in perfect readiness to move at the shortest notice.
I beg leave to congratulate your Excellency on the happy discovery; but am struck with astonishment at the horid treason.
The plot being laid open I think the Enemy will be altogether disconcerted for some days to come; and give you full time to make such dispositions for the better security of West Point as you may think necessary. I am with great respect your Excellencys Most Obedt humble Ser.
