He was also from time to time receiving all sorts of proposals of peace from emissaries or agents of the British government; and he had a long correspondence on this subject with David Hartley, who helped him to arrange the exchange of prisoners in England. Nearly all these proposals contained a trap of some kind, as that we should break our alliance with France and then England would treat with us, or that there should be a peace without a definite recognition of independence; and some of them may have been intended to entrap Franklin himself. It was, in any event, most dangerous and delicate work, for it was corresponding with the public enemy. Most men in Franklin’s position would have been compelled to drop it entirely, for fear of becoming involved in some serious difficulty; for it was suspected, if not actually proved, that persons connected with our own embassy in France were using their official knowledge to speculate in stocks in England. But Franklin came through it all unscathed. He was much annoyed by numerous applications from people who wished to serve in the American army. Most of them had proved failures in France and were burdens on their relations. In the early years of the embassy many were sent out who gave endless trouble and embarrassment to Washington and Congress. Out of the whole horde, only about three--Lafayette, Steuben, and De Kalb--were ever anything more than a nuisance. But, to avoid giving offence to the French people, Franklin was often obliged to give these applicants some sort of letter of recommendation, and he drew up a form which he sometimes used in extreme cases: “The bearer of this, who is going to America, presses me to give him a letter of recommendation, though I know nothing of him, not even his name. This may seem extraordinary, but I assure you it is not uncommon here. Sometimes, indeed, one unknown person brings another equally unknown, to recommend him; and sometimes they recommend one another! As to this gentleman, I must refer you to himself for his character and merits, with which he is certainly better acquainted than I can possibly be. I recommend him, however, to those civilities, which every stranger, of whom one knows no harm, has a right to; and I request you will do him all the good offices, and show him all the favor, that, on further acquaintance, you shall find him to deserve. I have the honor to be, &c.”
