A French Officer, Ensign de Vaisseau, a prisoner, of the name of Le Fevre, immediately jumped into the sea, and with great exertion and difficulty, though an excellent swimmer, saved the marine, and swam alongside almost exhausted : they were at length taken on board, and soon recovered. This generous trait of humanity being represented to the British Government, a free passport, without exchange, was directly sent express to the agent for prisoners of war at this port, for Le Fevre to return to his friends in France without any expence, with a certificate of his generous conduct to the French commissary at Morlaix : he sailed last week in the Betsey cartel, and is arrived safe at the above port.
