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.
