WASHINGTON TO HAMILTON AND DU PORTAIL.

West Point, October 21, 1779.

Gentlemen:

In my letters of the tenth and eighteenth, I transmitted all the intelligence I had obtained respecting the enemy, from the time of your departure to those two periods: and by the present conveyance, I inclose you an extract of a letter from Major-General Gates, of the 15th. By this you will perceive, he was fully persuaded that the enemy are now preparing to evacuate Rhode Island; and he expected, from his advices, they would do it on Monday or Tuesday last.

Whether the event has taken place, or not, as yet, is a matter I cannot determine, having received no information since upon the subject. But admitting it has not, there is no room to doubt that they have all things in a condition to do it, on the shortest notice, whenever they shall think the exigency of their affairs requires it. It is also equally certain, that they continue to carry on their fortifications for the defence of New-York with the utmost industry and perseverance; and appear to be providing for the most obstinate resistance. Indeed, as their reduction would be attended with the most alarming and fatal consequences to their nation, nothing else can be reasonably expected. The moment I hear the troops have left Rhode Island, I will advise you.

The garrisons at Verplanck’s and Stony Points, still remain; but from the concurring accounts of deserters, the heavy baggage and stores, except about eighteen or twenty rounds for each cannon, are embarked, and all matters are putting in train for an evacuation, in case events make it necessary. The deserters add, as a circumstance of confirmation, that Sir Henry Clinton was up at the posts about eight days ago; and that, from that time, they have totally declined carrying on any works.

Having given you the substance of the intelligence received since my last, I am led (from the vast magnitude of the object which carried you from head quarters, and the very interesting consequences it may involve, all of which I am persuaded will occur to your consideration) to remark, that the Count’s entering New-York Bay with his fleet, must be the basis and groundwork of any co-operation that can be undertaken by us, either for the reduction of the enemy’s whole force, or the destruction of their shipping only. Every thing will absolutely depend upon it, in either case; as, without it, and a free and open communication up and down the rivers, and in the Sound, which cannot be effected and maintained in any other way, we could not possibly undertake any operations on Long Island, as our supplies of provisions and stores could only be obtained by water.

This point, I am certain, would have your due consideration; but it appearing to me the hinge, the one thing upon which all others must rest, I could not forbear mentioning it. The circumstance of the season now, the expenditure of wood, and the necessity of supplying it, etc., will of course be fully attended to, according to their importance: and I have only to add, from a desire of preventing a misconception by either side, if any co-operation is agreed on, that the terms and conditions may be explicitly understood. And whether it shall extend to an attempt to reduce the enemy’s whole force, or only to the destruction of their shipping; your engagements will provide for the continuance of the Count’s fleet, to secure our retreat, and the removal of our stores from Long and York Islands, if, unhappily, it should be found, on experiment, that neither is practicable, and we should be obliged to abandon the enterprise.

I am, Gentlemen,
With great regard and respect,
Your most obedient servant,
G. Washington.
