Intelligence of the conclusion of the armistice was despatched to General Brock on the 12th August, by Brigade-Major Sheckleton, and must have reached him at Amherstburg before he left that place for Fort George, where he arrived the 6th September; but, whatever may have been General Brock's opinion of the policy of the measure, we do not find in his letter of the 7th September to Sir George Prevost, that the receipt of that intelligence had at all interfered with any intention he had previously entertained of "sweeping" (according to the Reviewer's assertion) "the Niagara line of the American garrisons, which he knew were then unprepared for vigorous resistance."[29] In fact, as that letter states, the armistice was to terminate the _next day_; and so far was General Brock from being in a situation to act offensively, that he states his expectation of an almost immediate attack, and of his having sent to Amherstburg to Colonel Proctor, as well as to Colonel Vincent at Kingston, for reinforcements, to enable him to meet it; expressing at the same time his hope, that if he could continue to maintain his position for six weeks longer, the campaign would terminate in a manner little expected in the United States. Upon the expiration of the armistice, Sir George Prevost resolved to continue, for a time at least, and until his resources would better enable him to pursue a contrary line of conduct, the same defensive system which he had previously determined upon; and which he had been originally induced to adopt, in consequence of the peculiar circumstances in which he was placed at the commencement of hostilities, and of the war having been undertaken, on the part of the United States, so much in opposition to the opinions and wishes of a considerable portion of its population. In a private letter from Sir George Prevost to General Brock, of the 2d August, 1812, upon the subject of the proposed armistice, he particularly refers to the opinion of Mr. Foster, respecting the policy of the defensive system. "Mr. Foster," he says, "submits the propriety of our abstaining from an invasion of the United States' territory, _as only in such event could the American government be empowered to order the militia out of the States_." As a further ground for this line of conduct, and a confirmation of the propriety of his own opinion in adopting it, he quotes in a subsequent communication to General Brock, of 30th August, 1812, the opinion of his Majesty's Government on the subject. "The King's Government having most unequivocally expressed to me their desire to preserve peace with the United States, that they might uninterruptedly pursue, with the whole disposeable force of the country, the great interests committed to them in Europe, I have endeavoured to be instrumental in the accomplishment of those views; but I consider it most fortunate to have been enabled to do so without interfering with your operations on the Detroit.
