Notwithstanding these observations, I have to assure you of my perfect confidence in your measures for the preservation of Upper Canada. All your wants shall be supplied as fast as possible, except money, of which I have so little, as to be obliged to have recourse to a paper currency. The adjutant-general has reported to you the aid we have afforded, in arms and ammunition, to your militia at Cornwall, Glengary, Dundas, and Stormont. To prevent an interruption to the communication between the two provinces, it is fit a system of convoy should be established between Montreal and Kingston; and as Major-General de Rottenburg is to remain here in command of a cordon of troops, consisting of regulars and militia, (established in this neighbourhood to prevent an irruption for the plunder of Montreal,) whilst I attend to parliamentary duties at Quebec, on that subject you may communicate direct with the major-general, as he has my instructions to co-operate with you on preserving this important object. _Major-General Brock to Sir George Prevost_. FORT GEORGE, July 12, 1812. With the exception of occasional firing from the opposite shore, (the unauthorized act of an undisciplined militia,) nothing of a hostile nature has occurred on this communication since I last had the honor of addressing your excellency. The enemy is busy constructing batteries at different points in the river, but he does not appear to have yet received cannon to place in them. We are doing all we can on this side to counteract his views, and the arrival this morning of the Royal George and the vessels under her convoy, bringing various pieces of ordnance, will give us in this respect a decided superiority.
