While American orators are thus employed in perpetuating the remembrance of the injustice and cruelty of Great Britain towards us, the French fleet has been giving such a check to her naval pride, as she has not experienced before for many ages. The vessel, which is to carry this, will carry information of a general engagement between d'Orvilliers and Keppel, which terminated in a disgraceful flight of the English fleet. We hope soon to hear of d'Estaing's success, which would demonstrate to the universe, that Britain is no longer mistress of the ocean. But the events of war are always uncertain, and a misfortune may have happened to the French fleet in America. But even if this should be the case, which I do not believe, still Britain is not mistress of the sea, and every day will bring fresh proofs that she is not. The springs of her naval power are dried away. I have hitherto had the happiness to find that my pulse beat in exact unison with those of my countrymen. I have ventured with some freedom to give my opinion, as to what Congress would do with the Conciliatory Bills, with the Commissioners, with the treaty, &c. &c. and every packet brings us proceedings of Congress, according in substance, but executed in a manner infinitely exceeding my abilities. Nothing has given me more joy, than the universal disdain that is expressed both in public and private letters, at the idea of departing from the treaty and violating the public faith. This faith is our American glory, and it is our bulwark. It is the only foundation on which our union can rest securely, it is the only support of our credit both in finance and commerce; it is our sole security for the assistance of foreign powers. If the British Court with their arts could shake it, or the confidence in it, we should be undone forever. They would triumph over us, after all our toil and danger. They would subjugate us more entirely than they ever intended. The idea of infidelity cannot be treated with too much resentment or too much horror. The man who can think of it with patience is a traitor in his heart, and ought be execrated as one, who adds the deepest hypocrisy to the blackest treason.
