My dear Brother,
In Eden's account of the conversation, in which M. de Montmorin notified to him the intention of France to assist their friends against the Duke of Brunswick's army, he mentions that an intimation was made of a strong wish on their part that means might yet be found for an amicable conclusion of the business, and a desire that the negotiation for that purpose might be pursued with more activity than ever.
Although it is very doubtful whether this is anything more than a persiflage, yet, as in their present situation their resolution may change every hour, it has been thought, after much consideration, that we ought so far to avail ourselves of it, as to try whether anything can be done in this way, but, at the same time, by no means to lessen or suspend our preparations. One of the difficulties on this subject was Eden's want of a competent knowledge of the points in dispute, to enable him to discuss them thoroughly, and to bring them to those short and distinct issues to which they must be reduced, if anything is to be done upon them in the very little time that now remains for negotiation. Another, and perhaps not the least of the two, was the strong bent of his mind to admit the assertions of the French Government, however unfounded, and to soften our communications, in order to keep back a rupture, which he has so great a personal interest to prevent, in addition to those motives which we all have in common for wishing the continuance of peace.
With a view to these considerations, I was earnestly requested to proceed to Paris for a fortnight or three weeks, in order to carry on this negotiation jointly with him. I have been very unwilling to accept this commission, because my opinion of the possibility of its success is much less sanguine than that of others. But I am satisfied that it is the duty of Government to leave nothing untried, however hopeless, which can enable us to maintain our ground without having recourse to extremities. And there is certainly, cæteris paribus, a better chance of doing this with the assistance of one who is in some degree acquainted with the particulars which are likely to come in question, and who will most undoubtedly state explicitly the real sentiments which are entertained here. For these reasons, I have thought myself not at liberty to refuse, and have given a reluctant consent.
I shall probably set out either to-morrow evening or Friday morning. It seems best for me not to go with any ostensible character, as that would be ridiculous in the case of my coming back re infectâ within a few days after my appointment. But in the other much less probable event, it would, I think, be right for me to have powers to sign with Eden.
It is, on the whole, a very hazardous undertaking, and one which, for a variety of reasons, I would gladly have avoided. I think I am sure to carry with me your warmest wishes for my success; and as I know the anxiety which you feel upon it, you may depend on hearing from me as soon as I have anything worth communicating, either good or bad.
In the meantime, believe me, with the truest affection,
My dear brother,
Most sincerely yours,
W. W. Grenville.
P.S. There is no news, either from Harris or Eden, since I wrote.
Two days afterwards, Mr. Grenville, in a few hasty lines, informs his brother that he is that instant setting out for France. "Accounts were at this moment received," he concludes, "that Utrecht and all the towns in North Holland had surrendered to the Prussian troops; and that the Free Corps were all called in to Amsterdam, which they talked of defending."
