I have just received your letter of the 8th of this month, and the packets which accompanied it. I have not now time to reply to it, as I profit by an express on the point of departure, and whom I cannot detain.
The movements of the English troops at New York, indicate an intention of sending off detachments from that garrison. It is even possible, though not very probable, that they propose to evacuate that place, either to reinforce the English Islands, or to act offensively against the conquered Islands, which will not be in so good a state of defence as our ancient possessions. This last supposition cannot take place, unless they retain their superiority, and although I hope that this will not be the case, it is, however, but prudent to be in readiness against every event.
The most sure means of preventing the enemy from making any detachment from New York, is to approach that place, and to give a jealousy to General Carlton, of a combined attack. Congress regard the matter in this light, and think that General Washington will make a movement towards New York, in case such a measure is agreeable to his designs, or to the intelligence he may have. I am ignorant what steps he will take in this conjuncture. It is possible that he may think it proper not to quit his present station, till he hears that you approach. In all cases the enemy will be cautious of weakening themselves, if they hear that you are on the march to form a junction.
I submit these ideas to you, my Dear General, and am persuaded that you will take such measures as are most advantageous.
We have news, which I have no reason to believe that M. de la Motte Piquet is not far distant from these coasts.
I have the honor to be, &c.
LUZERNE.
GEORGE WASHINGTON TO M. DE LA LUZERNE.
