on the Niagara frontier, we shall only mention that Major-General Brock states, in a MS. before us, that it was the strong American force on that frontier which compelled him to take with him to Detroit only half of the militia, who volunteered. _Sir George Prevost to Earl Bathurst._ Head Quarters, Montreal, Sept. 1, 1812. Since I had the honor of transmitting to your lordship my letter of the 26th ultimo, in charge of my aide-de-camp, Captain Coore, I have received from Major-General Brock a dispatch, of which the enclosed is a copy, containing the particulars of Brigadier-General Hull's invasion of Upper Canada, which has terminated most gloriously to his majesty's arms, in that officer's defeat and surrender, as a prisoner of war, with the whole of the north-western army, together with the fort Detroit, and thirty-three pieces of ordnance. I forward this dispatch express, in the expectation of its reaching Captain Coore previously to his leaving Canada, which, with the colours of the 4th United States' regiment accompanying it, I trust that officer will have the honor of delivering to your lordship. _Earl Bathurst to Sir George Prevost._ DOWNING STREET, October 10, 1812. I have had the honor of receiving your dispatch, dated the 26th August, together with its enclosures, from Major-General Brock, and I lost no time in laying intelligence so important and satisfactory before his royal highness the prince regent. I am commanded by his royal highness to desire you to take the earliest opportunity of conveying his royal highness' approbation of the able, judicious, and decisive conduct of Major-General Brock, of the zeal and spirit manifested by Colonel Proctor and the other officers, as well as of the intrepidity of the troops under the command of Major-General Brock. By the united exertions of this little army, the enterprize of the American army has been defeated; the territories of his majesty in Upper Canada have been secured; and on the enemy's fort of Detroit, important to that security, the British standard has been happily placed. You will inform Major-General Brock that his royal highness, taking into consideration all the difficulties by which Major-General Brock was surrounded from the time of the invasion of the province by the American army, under the command of General Hull, and the singular judgment, firmness, skill, and courage, with which he was enabled to surmount them so effectually--has been pleased to appoint him an extra knight of the most honorable order of the bath. * * * * *
