In the month of August Sir George Prevost again repaired to Montreal, in order that he might be ready to take the field, should the movements of General Dearborn, who commanded the enemy's forces on that frontier, indicate any intention of attacking our line of defence, which had been entrusted to the charge of Major-General de Rottenburg. General Dearborn having, on the 16th November, advanced from Plattsburg to Champlain town, close upon our frontier line, thereby threatening the front of Major-General de Rottenburg's position, Sir George Prevost, upon the receipt of this intelligence, crossed the St. Lawrence with a considerable proportion of the force then at Montreal, in order to strengthen the point thus threatened, and established his head-quarters at Chambly, where he remained for several weeks. Whether this movement on the part of General Dearborn was made in the expectation of finding that no effectual resistance would be offered by the Canadian population to his further advance into the Province, or with the view of preventing the sending of reinforcements from the Lower to the Upper Province, he was equally disappointed in both these objects. The able measures adopted by Sir George Prevost in the disposition of the regular troops, as well as of the militia, who displayed the most ardent spirit of loyalty, and the most resolute determination to repel every attempt of the enemy to invade the Colony, induced the American Commander in Chief to abandon any further intention of advancing. After pushing forward a few reconnoitring parties which were invariably forced to retreat without effecting their object, he was ultimately compelled, by the advanced season of the year, to close the campaign, and to put the army into winter quarters. The result of the first campaign was highly honorable to the military talents of the Commander of the forces. The enemy, notwithstanding their superior resources, were foiled in every attempt which they made to invade the Provinces, with the loss in one instance of the whole of their army, together with the Commander; while, in the other, their troops suffered a total defeat, attended with the capture of a General Officer, and upwards of 700 men. But while thus engaged in his military duties, Sir George Prevost was not unmindful of the importance of our naval superiority upon the Lakes, though in this as in every other part of his conduct, he has fallen under the indiscriminate censure of the Quarterly Reviewer,[34] who has accused him of neglecting to preserve the naval ascendancy which we enjoyed on Lakes Erie and Ontario, at the commencement of the contest.
