Capt. [James] Robinson, of the ship Nancy and Sukey (who arrived in this port last Wednesday [October 11]) left London the 10th, the Downs the 14th, and Falmouth the 25th of August: He parted company with the Lizard frigate, of 28 guns, Capt. John Inglis, on the 22d of August, at Torbay.ー The Lizard was ordered to Quebec, and had under her convoy a brigantine, Capt. Brown, who informed Capt. Robinson, that he had on hoard 6000 stand of small arms, several brass cannon, and a large quantity of gunpowder. Capt. Brown's vessel was so heavy a sailer, that the frigate was obliged to take her in tow coming down the channel. Capt. Brown informed Capt. Robinson, that a brigantine, under convoy of a frigate, had sailed for Virginia with arms and ammunition, but, by strong westerly winds, was forced to put back, and had gone into Spithead.
