You wrote to the Chevalier de Chastellux, my dear marquis, that the interview I requested of our general has embarrassed him, because it only becomes necessary after the arrival of the second division, when there will be quite time enough to act. But you must surely have forgotten that I have unceasingly requested that interview immediately, and that it is absolutely necessary that he, the admiral, and I, should concert together all our projects and details, that in case one of the three chances should occur and enable us to act offensively, our movements may be prompt and decisive. In one of these three cases, my dear marquis, you will find in your old prudent father some remnants of vigour and activity. Be ever convinced of my sincere affection, and that if I pointed out to you very gently what displeased me in your last despatch, I felt at the time convinced that the warmth of your heart had somewhat impaired the coolness of your judgment. Retain that latter quality in the council-room, and reserve all the former for the hour of action. It is always the aged father, Rochambeau, who is addressing his dear son Lafayette, whom he loves, and will ever love and esteem until his latest breath.

TO THE CHEVALIER DE LA LUZERNE.

Robinson House, opposite W. Point, Sept. 26, 1780.

When I parted from you yesterday, sir, to come and breakfast here with General Arnold, we were far from foreseeing the event which I am now going to relate to you.~{1}

You will shudder at the danger to which we have been exposed; you will admire the miraculous chain of unexpected events and singular chances that have saved us; but you will be still more astonished when you learn by what instruments this conspiracy has been formed. West Point was sold—and sold by Arnold: the same man who formerly acquired glory by rendering such immense services to his country. He had lately entered into a horrible compact with the enemy, and but for the accident that brought us here at a certain hour, but for the combination of chances that threw the adjutant-general of the English army in the hands of some peasants, beyond the limits of our stations, West Point and the North River, we should both at present, in all probability, be in possession of the enemy.

When we set out yesterday for Fishkill, we were preceded by one of my aides-de-camp, and one of General Knox's, who found General Arnold and his wife at breakfast, and sat down at table with them. Whilst they were together, two letters were given to Arnold, which apprised him of the arrestration of the spy. He ordered a horse to be saddled, went into his wife's room to tell her he was ruined, and desired his aide-de-camp to inform General Washington that he was going to West Point and would return in the course of an hour.

On our arrival here, we crossed the river and went to examine the works. You may conceive our astonishment when we learnt, on our return, that the arrested spy was Major André, adjutant-general of the English army; and when amongst his papers were discovered the copy of an important council of war, the state of the garrison and works, and observations upon various means of attack and defence, the whole in Arnold's own hand writing.

The adjutant-general wrote also to the general, avowing his name and situation. Orders were sent to arrest Arnold; but he escaped in a boat, got on board the English frigate the Vulture, and as no person suspected his flight, he was not stopped at any post. Colonel Hamilton, who had gone in pursuit of him, received soon after, by a flag of truce, a letter from Arnold to the general, in which he entered into no details to justify his treachery, and a letter from the English commander, Robertson, who, in a very insolent manner, demanded that the adjutant-general should be delivered up to them, as he had only acted with the permission of General Arnold.

The first care of the general has been to assemble, at West Point, the troops that, under various pretences, Arnold had dispersed. We remain here to watch over the safety of a fort, that the English may respect less as they become better acquainted with it. Continental troops have been summoned here, and as Arnold's advice may determine Clinton to make a sudden movement, the army has received orders to be prepared to march at a moment's warning.
