In September 1799, Lieutenant
Jeremiah Coghlan (acting) assumed command
HMS Viper. On 1 November
Viper recaptured the
Diamond. In July 1800, Coghlan, who had been watching
Port-Louis, Morbihan, proposed to Sir
Edward Pellew that he, Coghlan, take some boats into the harbour to cut out one of the French vessels there. Pellew acceded to the proposal and gave Coghlan a cutter from
Impetueux, Midshipman Silas H. Paddon, and 12 men. Coghlan added in six men from
Viper, a boat from
Viper, and one from . On 29 July the boats went into the port after dark, targeting a brig. During the run-up to the attack the boats from
Viper and
Amethyst fell behind, but Coghlan in the cutter persisted. The Royal Navy took
Cerbère into service under her existing name. Pellew's fleet waived their right to any prize money as a gesture of admiration for the feat. ==British service and fate==
