The very flattering manner in which your excellency is pleased to view my services, and your kindness in having represented them to his majesty's ministers in such favorable light, are gratifying to my feelings, and call for my grateful acknowledgments. _Major-General Brock to Sir George Prevost._ FORT GEORGE, September 9, 1812. I have been honored with your excellency's dispatch, dated the 24th ultimo, and have to thank you for ordering a company of the Glengary regiment to strengthen Colonel Lethbridge at Prescott, whose force you have been led to believe was weakened in consequence of my interference, but which, I beg leave to state, was done without my knowledge, and contrary to my intention. The enclosed copies of letters will inform you of the state of affairs to the westward. It appears evident the enemy meditates a second attempt on Amherstburg. The greater part of the troops, which are advancing, marched from Kentucky with an intention of joining General Hull. How they are to subsist, even for a short period, in that already exhausted country, is no easy matter to conceive. This difficulty will probably decide them on some bold measure, in the hope of shortening the campaign. If successfully resisted, their fate is inevitable. The Indians, it appears by the accompanying documents, were adverse to retreating without first making a trial of their strength. Taking, however, every circumstance into consideration, I am inclined to think that Captain Muir acted judiciously. Should the Indians continue to afford a willing co-operation, I entertain not the smallest doubt of the result that awaits this second attempt to turn my right; but your excellency will easily perceive that doubts and jealousies have already seized their minds. The officers of the Indian department will, I trust, be able to remove all such impressions. Although, from the daily observations of what is passing on the opposite shore, a single man can ill be spared from this line, I have notwithstanding determined to send the two flank companies of the royal Newfoundland regiment to Amherstburg. Fresh troops are daily arriving, supposed to belong to the Pennsylvania quota of 2,000 men, known to be intended for this frontier. After the whole arrive, an attack, I imagine, cannot be long delayed. The wretched state of their quotas, and the raggedness of the troops, will not allow them to brave the rain and cold, which during the last week have been so severely felt.
