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 every place wherever they attempted to make a stand. The rout became general, and the pursuit continued for about two miles, to the village of Brownstown, where the British took to their boats, and the Indians to the woods.—Col. Miller had directed a charge to be made by the Cavalry, while the enemy were in full rout; which was not done, although Capt. Snelling offered himself to lead them on in person. This cowardice of the Cavalry alone saved the enemy from destruction. In the action an Indian had climbed into the top of a large tree, from which he discharged many arrows into our ranks, but was discovered by the soldiers, and brought down very suddenly. Another Indian who had been wounded, and lay in the woods unable to move from his place, had loaded his rifle and shot down a militia soldier, who was in search of some of his fallen comrades; a party near by heard the report of the rifle, came up and dispatched the Indian while in the act of reloading, for another victim who might pass in his way.—Our killed and wounded were collected before dark and brought to the camp; consisting of 18 killed and 58 wounded. The loss of the British and Indians were 100 killed, and nearly twice that number wounded. Many of them were picked up and brought into camp the same evening, and their wounds carefully attended to. The British were commanded in this action by Major Muir, and the Indians by Tecumseh, Marpot and Walk-in-the-water. Their force consisted of three hundred Regulars and five hundred Indians, nearly one third greater than the American force under Col. Miller.
The only Officers of the 4th Regt. wounded, were Lieut. Larabee, a brave officer who lost an arm—and Lieut. George P. Peters, who commanded the late Capt. Wentworth's company.
Aug. 10.—Boats from Detroit arrived to take up the wounded. On their return they were fired upon by the British brig Hunter, and even after the wounded were transferred from the boats to waggons, this vessel took several positions to harass them on their return to Detroit.
Col. Miller had determined to push on to the river Raisin; for which purpose the troops were paraded in readiness to march; but the Col. was suddenly attacked by a fit of the fever and ague, with which he had been partially afflicted from the time of his severe illness at Fort Harrison in Indiana. We therefore continued on the ground this day, expecting provisions from Detroit, but none arrived. We observed the British to be busy in crossing over troops from Malden a few miles below us, and concluded they intended an attack upon our encampment the following night. About sunset an express arrived in Camp from the General at Detroit, with a peremptory order for the troops to return that evening to the river De Coss. We were immediately formed and proceeded on our return. It having rained the whole of the day, and the night being extremely dark, it was with great difficulty we reached the river; being without tents we were wet to the skin; many lost their shoes in the mud and came on barefoot. About 2 o'clock the next morning we arrived at the river, and after partaking of some refreshment, which had been sent to this place, we spread our blankets, which were wet as well as the ground we lay upon; and notwithstanding our uncomfortable situation we slept soundly until day light.
Aug. 11.—Continued on our march, re-crossed the river De Coss, and arrived at Detroit about 12 o'clock.
Aug. 12.—The British had taken possession of the ground we had abandoned at Sandwich, and commenced throwing up their works; at which they continued without interruption until the 15th, working in open day. Our troops were also employed in erecting batteries on the bank of the river, opposite to those of the British.
Aug. 14.—A detachment of three hundred and fifty troops from M'Arthur's and Cass' regiments were ordered to the river Raisin to escort up the provisions which had so long remained there under the protection of Captain Brush. This was the third detachment which had been sent on that service.
Aug. 15.—The enemy had completed their batteries, and about 10 o'clock, P.M. Gen. Brock, the British commander, sent over a flag of truce from Sandwich, with a summons for the surrender of the town and fort; stating that he could no longer restrain the fury of the savages, and should at 3 o'clock, commence a cannonade upon the place unless the summons was complied with. A prompt and spirited refusal was returned. At 4 o'clock their batteries were opened upon the town, from two 18 pounders and a howitzer. Their fire was briskly returned from our two batteries of three 24 pounders, and continued without interruption until dark. In the evening they commenced throwing shells, and did not cease until 9 o'clock. No person was hurt, or but little damage done, except to a few buildings in the town.
