_Major-General Brock to Sir George Prevost._ YORK, August 4, 1812. I have the honor to enclose a statement made by me yesterday to his majesty's executive council, which will fully apprize your excellency of my situation. The council adjourned for deliberation, and I have no doubt will recommend the prorogation of the assembly and proclamation declaring martial law, but doubts occurred in contemplation of such an event, which I take the liberty to submit to your excellency, and request the aid of your experience and superior judgment. 1.--In the event of declaring martial law, can I, without the sign manual, approve and carry into effect the sentence of a general court martial? 2.--Can I put upon a general court martial, after martial law is proclaimed, any person not a commissioned officer in his majesty's regular forces? In other words, can officers of militia sit in conjunction with those of the line? _Sir George Prevost to Major-General Brock_. MONTREAL, August 12, 1812. Your letter of the 4th instant, enclosing the proceedings of the executive council of the 3d.; Captain Glegg's letter of the 5th instant, transmitting copies of letters from Colonel Proctor to you of 26th and 30th July, with the correspondence between Brigadier-General Hull and Lieut.-Colonel St. George, and the intercepted correspondence of the former, together with your letter to Colonel Baynes, of the 4th instant, were all delivered to me on my arrival at this place yesterday. The information they contain is highly interesting, and I lose no time in dispatching to you Brigade Major Shekleton, as the bearer of this letter, and for the purpose of receiving whatever communication you may have to make in return. Being fully aware of the necessity of affording you such reinforcements as the exigencies of the service in other parts of the two provinces would permit, I had, previous to the receipt of your letter, made arrangements for that purpose. Major Ormsby, with three companies of the 49th regiment, protecting a considerable supply of ordnance and ordnance stores, left La Chine on the 6th instant for Kingston and Fort George, taking with him £2,500 for the payment of the regular and militia forces. Major Heathcote, with one company of the 49th regiment, about 110 men of the Newfoundland regiment, and 50 picked Veterans, are to leave La Chine on the 13th instant. With this detachment, an additional supply of ordnance stores and camp equipage for 500 men will be forwarded for Upper Canada; and as soon as a sufficiency of bateaux can again be collected at La Chine, Colonel Vincent is under orders to proceed to Kingston with the remainder of the 49th regiment, and a subaltern of the royal artillery and ten gunners, with two 3-pounders.
