Advice is received here from L'Orient, that a vessel is arrived there, which had been boarded off Cape Finisterre, by a large schooner privateer of 14 guns, who put on board her the crew of two British vessels she had taken, one loaded with oats, the other with cod-fish; and that the said privateer had an engagement with one of our outward-bound transports, which mounted 10 guns, and obliged the privateer to sheer off, having had two men killed and 10 wounded.
