It appears by every account I have been able to collect, that a little before day a number of boats full of men, dropped down with the current unobserved, boarded both vessels at the same moment, and, cutting their cables, were proceeding with them to the American shore, when Major Ormsby, who witnessed the transaction, directed the batteries to open on them, and soon compelled the enemy to abandon the Detroit, which grounded about the centre of Squaw Island, a little more than a mile below Black Rock.

She was then boarded by a party of the 49th regiment; but as no anchor remained, and being otherwise unprovided with every means by which she could be hauled off, the officer, throwing her guns over board, after sustaining a smart fire of musketry, decided to quit her.

A private, who is accused of getting drunk, and a prisoner of war, who was unable from his wounds to escape, with about twenty prisoners brought by the Detroit from Amherstburg, remained however behind; these it became necessary to remove before the vessel could be destroyed, and Cornet Pell Major, of the provincial cavalry, offered his services.

Being unfortunately wounded as he was getting on board, and falling back into the boat, a confusion arose, during which the boat drifted from the vessel, leaving two of the 41st, who had previously ascended, on board.

In the mean time the Caledonia was secured by the enemy, and a cargo of furs, belonging to the North-West Company, landed.
The batteries on both sides were warmly engaged the whole of the day, but I am happy to say no mischief was sustained by the enemy's fire.
