Action Upon Lake Ontario - On Sunday the 19th ult. at 9 A. M. the Royal George, the Prince Regent and two brigs, entered Sacket's Harbor, came within one and a half mile of the town and commenced an attack-and continued the cannonade about one hour, during which time one ball only (a 32 pounder) reached the shore. The brig Oneida lay in shore, all her guns were unshipped and with two nine's mounted upon a redoubt thrown up on Friday and Saturday preceding by order of Maj. Gen. Van Renssaeler. Two shot from the nine's hulled the Royal George - and one shot carried way the foretop gallant-mast of the Prince Regent, when the British squadron bore away. The British squadron had captured a revenue cutter, and sent the men ashore, with a message that unless the brig which had been taken by Capt. Woolsey was immediately restored they would burn the town. - Albany Gazette of July 23.
