By a Gentleman just arrived from Charles-Town, we are informed, that one of the large three decked Ships lately carried in there by Capt. Biddle in the Randolph continental Frigate, proves to be a Prize taken by Capt. Palmer in the Privateer Nancy, belonging to Mr. John W. Stanly of this Town. It seems a few Days after Capt. Palmer took her, a large Ship of 20 Guns from Jamaica retook her, in a Day or two after which the Randolph fell in with them both and conducted them safe to Charles-Town. The Nancy has also taken a Guinea-Man with 100 Slaves, Ivory, and other Valuables, and sent her into Georgia.
