Capture of Oswego. - The particulars of this new disaster we have not been able to collect. The force of the enemy is reported to have been between 1,000 and 2,000, and their loss great - our loss in killed and wounded between 50 and 100. They destroyed the barracks and all public property (to a considerable amount) on both sides of the river, and then evacuated the place. The expedition is said to have been commanded by Maj. Gen. Drummond, who was wounded in the groin.
P.S. Since the above was in type, we learn that the British again landed at Oswego on Monday last, at about 10 in the morning, evidently with an intention of carrying away or destroying the cannon and naval stores deposited at Oswego Falls; and that the militia of the adjacent country were collecting to repel the invasion.
