If there should be a naval battle between M. de Ternay and Admiral Graves, the event is uncertain. From the near equality of force, and the equality of bravery and of naval science which now prevails everywhere, I think we cannot depend upon anything decisive in such an engagement, unless it be from the particular character of Graves, whom I know personally to be neither a great man, nor a great officer. If there should be no decision in a naval battle, Graves and his fleet must lay at New York, and M. de Ternay and his, at Rhode Island. I readily agree, that this will be a great advantage to the common cause, for the reasons mentioned in my letter to your Excellency of the 13th of this month. But still I beg leave to suggest to your Excellency, whether it would not be for the good of the common cause to have still further resources in view, whether circumstances may not be such in the West Indies, as to enable M. de Guichen to despatch ships to the reinforcement of M. de Ternay, or whether it may not consist with the King's service to despatch ships from Europe for that purpose, and further, whether the Court of Spain cannot be convinced of the policy of keeping open the communication between the United States and the French and Spanish Islands in the West Indies, so as to co-operate with France and the United States in the system of keeping up a constant superiority of naval power, both upon the coasts of North America and in the West India Islands. This is the true plan which is finally to humble the English, and give the combined forces the advantage. The English, in the course of the last war, derived all their triumphs, both upon the Continent of America and the Islands, from the succors they received from their Colonies. And I am sure that France and Spain, with attention to the subject, may receive assistance in this war, from the same source equally decisive. I have the honor to be, &c. JOHN ADAMS.

Sir, I have received the letter, which you did me the honor to write me on the 27th of this month. When I took upon myself to give you a mark of my confidence, by informing you of the destination of Messrs de Ternay and Rochambeau, I did not expect the animadversion, which you have thought it your duty to make on a passage of my letter of the 20th of this month. To avoid any further discussions of that sort, I think it my duty to inform you, that Mr Franklin being the sole person who has letters of credence to the King from the United States, it is with him only that I ought and can treat of matters, which concern them, and particularly of that which is the subject of your observations.
