Although your letter of yesterday's date fully authorizes me to any act of hostility against the army of the United States of America in this neighborhood under your command, yet, still anxious to prevent that dreadful decision, which perhaps is not intended to be appealed to by either of our countries, I have forborne for these two days past to resent those insults which you have offered to the British flag flying at this fort, by approaching it within pistol-shot of my works, not only singly, but in numbers, with arms in their hands. Neither is it my wish to wage war with individuals. But should you after this continue to approach my post in the threatening manner you are at this moment doing, my indispensable duty to my King and Country, and the honor of my profession, will oblige me to have recourse to those measures which thousands of either nation may hereafter have cause to regret, and which I solemnly appeal to God I have used my utmost endeavors to arrest. I have the honor to be, sir, &c. (Signed) WM. CAMPBELL. To Major General Wayne, &c. [No other notice was taken of this letter than what is expressed in the following letter. The fort and works were however reconnoitered in every direction, at some points possibly within pistol-shot. It was found to be a regular, strong work, the front covered by a wide river, with four guns mounted in that face. The rear, which was the most susceptible of approach, had two regular bastions furnished with eight pieces of artillery, the whole surrounded with a wide deep ditch. From the bottom of the ditch to the top of the parapet was about twenty feet perpendicular. The works were also surrounded by an abbatis, and furnished with a strong garrison.] (IV) Sir, In your letter of the 21st inst. you declare, "I have no hesitation on my part to say that I know of no war, existing between Great Britain and America." I, on my part, declare the same; and the only cause I have to entertain a contrary idea at present is, the hostile act you are now in commission of,--that is, recently taking post far within the well known and acknowledged limits of the United States, and erecting a fortification in the heart of the settlements of the Indian tribes now at war with the United States. This, sir, appears to be an act of the highest aggression, and destructive to the peace and interest of the Union. Hence, it becomes my duty to desire, and I do hereby desire and demand, in the name of the President of the United States, that you immediately desist from any further act of hostility or aggression, by forbearing to fortify, and by withdrawing the troops, artillery, and stores under your orders and direction, forthwith, and removing to the nearest post occupied by His Britannic Majesty's troops at the peace of 1783--and which you will be permitted to do unmolested by the troops under my command.
