August 4--Major Van Horn, of Col. Findley's regiment was detached with 200 men to the river Raisin, for the purpose of escorting a quantity of provisions to the army, which were at that place under the charge of Capt. Brush. He was attacked in the woods of Brownstown by a large body of Indians while his men were partaking of a little refreshment. So sudden and unexpected was the attack that it was impossible to form the men in line of battle, although every exertion was made by the officers for that purpose. In this defeat seven officers and ten privates were killed, and many more wounded--They retreated in great disorder, leaving part of their killed on the field. Aug. 5.--Orders are at last issued by Gen. Hull for the army to be in readiness to take the field against the enemy; the first step for this purpose, was to _abandon_ our position in Upper Canada, and return to Detroit; which was accomplished on the night of the 6th, leaving a detachment, however, to garrison a small fort we had built during our stay at Sandwich: this also was shortly after set fire to and abandoned. Aug. 8.--In consequence of the failure of the expedition under Major Van Horn, the 4th Regt. with a detachment from the militia, all under the command of Col. Miller, left Detroit about 3 o'clock P.M. and proceeded on our march to open the communication with Capt. Brush, who had fortified himself on the banks of the river Raisin. A little past sunset we arrived at the river De Coss, which we crossed, and encamped without tents.--Early next morning continued our march and about 12 o'clock our Cavalry were fired upon by some Indian scouts, who had stationed themselves behind an old log hut, and killed one and wounded another of the dragoons. The line of battle was instantly formed, and we advanced rapidly forward, for a considerable distance, but no enemy could be discovered.--We halted to refresh on an open field, where we tarried a short time, and again proceeded on our march.--At 3 o'clock, P.M. the vanguard, commanded by Capt. Snelling, was fired upon by an extensive line of British troops. Capt. Snelling maintained his position in a most gallant manner until the main body could be formed in line of battle, and advance to his relief; when the whole, excepting the rear guard was brought into action in a masterly style by our brave Commander.--The enemy were formed in an advantageous position behind a breast-work of felled trees; we had advanced but a few rods towards their works before a large body of Indians arose upon each flank of the British and poured a tremendous fire of rifles into our ranks; and in a moment dropped down behind their logs. We still continued on the advance, and could discover nothing but the smoke from their discharge until nearly upon them with the bayonet, which they perceived, before they had time to reload, and retreated to a second breast-work; but they, as well as the British, were driven from
