Philadelphia, January 4th, 1783.

Dear Sir,

I have before me your despatches of the 4th and 18th of September last, and the 13th of October. It gives me much uneasiness to find by them, that your health is not yet confirmed, particularly as the extreme shortness of your letters, compared with the importance of the matter, gives me reason to fear, that it has suffered more than you would have us believe.

I am under some anxiety relative to the fate of your letter of the 18th of September, as only the duplicate copy has arrived, and I find by that you have risked it without a cypher. Should it get into improper hands, it might be attended with disagreeable consequences.

It is of so much importance, that both you and we should judge rightly of the designs of the Court, to whom we have intrusted such extensive powers, that I most earnestly wish you had enlarged on the reasons which have induced you to form the opinion you intimate; an opinion, which, if well founded, must render your negotiations extremely painful, and the issue of them very uncertain. If on the other hand, it should have been taken up too hastily, it is to be feared, that in defiance of all that prudence and self-possession, for which you are happily distinguished, it will discover itself in a reserve and want of confidence, which may afford hopes to our artful antagonists of exciting jealousies between us and our friends. I so sincerely wish that your conjectures on this head may not be well founded, that I am led to hope you carry your suspicions too far, and the more so as Dr Franklin, to whom I dare say you have communicated them freely, does not (as you say) agree in sentiment with you. But I pretend not to judge, since I have not the advantage of seeing from the same ground. Perhaps some light may be thrown upon the subject by such facts as I have been able to collect here, and with which it is impossible you should be acquainted.

The policy you suppose to influence the measures of France, can only be founded in a distrust, which I persuade myself she can hardly entertain of those who have put their dearest interest into her hands. She is too well informed of the state of this country, to believe there is the least reason to suppose, that we could have the most distant idea of a separate peace. If such distrust really exists, it would, in my opinion, dictate to them, to let Great Britain acknowledge our independence at once, rather than make it the subject of subsequent negotiation. When satisfied on that point, we can with more advantage contend for those our allies have at heart. Whereas by withholding it, and making it the price of concessions on the part of France, which she may not choose to make, an opportunity would be afforded, to embroil and incline us to listen to separate proposals. Upon this principle, France seems to have acted in all the answers, which she has hitherto given, as well to the direct proposals of Great Britain as to those made by the imperial Courts. When Mr Grenville proposed to treat of the independence of the United States with his Most Christian Majesty, an opportunity was afforded to take the lead in the negotiation, and to suspend that part of it; yet we find the reply of the Court of Versailles led to a direct negotiation between Great Britain and us, and ended in the offer of unconditional independence. The reply of the Court of France to that of London, communicated to Mr Grenville on the 21st of June, speaks the same language.

From these and the following facts you will, when you have compared them with those within your own knowledge, draw your inferences with more judgment than I can pretend to do without those you possess.

Before your letters were received, the Chevalier de la Luzerne showed me a letter from the Count de Vergennes of the 14th of August, in which he speaks of Mr Grenville's commission, and the ground it gave him to hope, that negotiations would open with an express and unconditional acknowledgment of independence. He mentions the change in the British administration; their assurances, that it should occasion no alteration in the plan of their negotiation, and concludes, by expressing his surprise at the alteration, which afterwards took place in this essential article in the propositions offered by Mr Fitzherbert, and infers from thence, that Lord Shelburne had no other design than to divide and deceive. In a letter of the 7th of September, he mentions Mr Oswald's commission, your objections to it, and his doubts of the manner in which these objections will be received. "If," says he, "Mr Oswald is right in his conjecture, that they will be favorably received and removed, then everything is said. If they reject them, because they will not begin where they propose to end, I conceive the negotiations should still go on. We may judge of the intentions of the Court of London by their first propositions. If they have independence for their basis, we may proceed; if not, we must break off." In his letter of the 14th of October, he mentions with great apparent satisfaction, the alterations in Mr Oswald's commission. From the general tenor of these letters, I can discover nothing but an anxious desire for peace, which might very naturally lead him to wish that objections, which he did not conceive essential in the first instance, after having declared to Great Britain that no peace could be made till our independence was acknowledged, should not break off a negotiation, which must end in the attainment of an object, which they have as much at heart as we.

Whatever the sentiments of the Count de Vergennes may be, as to the claim of Spain, in a letter which I have seen, he treats them as well as ours, as chimerical and extravagant, and declares, that he does not mean to interfere in them. You can best judge of the sincerity of this declaration. If insincere, I cannot conceive for what purpose it was made, or the subject treated so lightly, or why this should be confided to me. For my own part, I believe their situation with respect to Spain is very delicate, and that they are embarrassed by her demands. I mention these things, that you may, by comparing them with facts within your reach, draw useful inferences from them, and I wish to give you everything that may possibly be of use to you.

As to the letter of Marbois, I am by no means surprised at it, since he always endeavored to persuade us that our claim to the fisheries was not well founded. Yet one thing is very remarkable, and I hope evinces the determination of France to serve us on this point. The advice given to discourage the hope is certainly judicious, and yet we find no steps taken in consequence of it. On the contrary, we have been repeatedly told in formal communications since that period, "that the King would do everything for us that circumstances will admit, and that nothing but dire necessity shall induce him to relinquish any of the objects we have at heart, and that he does not imagine that such necessity will exist." This communication was made on the 21st of last November, from letters of the 7th of September, previous to our success at Yorktown, and has been renewed at different periods since. You will undoubtedly avail yourself of this engagement if necessary. Congress relying upon it, have made no alteration in their instructions since the change in their affairs, by the blow the enemy received at Yorktown.
