I am much disappointed that the particulars of the surrender of Detroit have not as yet reached me, particularly as my aide-de-camp, Captain Coore, is to leave Montreal this evening for Quebec, where a ship of war is on the point of sailing for Halifax, from whence I expect the admiral will give him a conveyance for England. Being unacquainted with the conditions attached to the surrender of Brigadier-General Hull's army, and giving scope to your expression of prisoners of war, I have made arrangements for increasing their security against any attempt to rescue them, by ordering Captain Gray to proceed with two flank companies to Prescot. [The dispatch from General Dearborn, dated Greenbush, August 26, was to announce the discontinuance of the temporary armistice agreed to between him and Colonel Baynes, in four days after the receipt of the communication at the frontier posts in Canada. The American general added: "If a suspension of offensive operations shall have been mutually consented to between General Hull and the commanding officer of the British forces at and near Detroit, as proposed, they will respectively be authorized, at the expiration of four days subsequent to their receiving copies of this communication, to consider themselves released from any agreement thus entered into."] * * * * * As we have already commented on Sir George Prevost's management of the war, and shall have occasionally to do so again, we gladly give him credit for the very handsome manner in which he spoke of Major-General Brock, in his dispatch to Earl Bathurst, one of his majesty's principal secretaries of state, announcing the surrender of Detroit, and dated Montreal, 26th August, 1812. "It was under these circumstances at this critical period, and when the enemy were beginning to consult their security by entrenching themselves, that General Brock entered Amherstburg with a reinforcement, which he was fortunately enabled to do on the 13th instant, without the smallest molestation, in consequence of our decided naval superiority on the lakes. To his active and intelligent mind, the advantages which his enemy's situation afforded him over them, even with his very inferior force, became immediately apparent; and that he has not failed most effectually to avail himself of those favorable circumstances, your lordship will, I trust, be satisfied, from the letter which I have the honor of transmitting.
