Those Northern Powers, against whom Britain had reluctantly drawn the sword, experienced a severe and early chastisement in the loss of all their West India Colonies, which successively yielded to the prompt and vigorous measures of Admiral Duckworth and Sir Thomas Trigge. St. Bartholomew's, St. Martin's, which alone offered any resistance, St. Thomas, and Santa Cruz submitted to the Army and Fleet during the month of March, and the islands of St. Eustatius and Saba were occupied by our forces in April. These conquests afforded no field for achievement, but they gave opportunities for the display of much united zeal. Captains Manby and Butcher, their Officers, Seamen, and Marines were noticed for gallant single actions, and Lieutenant Mackenzie, with those under him, for much intrepidity in cutting out a schooner from under the batteries at Guadaloupe. It is with a heartfelt pain that I am constrained to blend with these honorable details, another instance of baneful insubordination which occurred on board the Castor frigate, upon Sunday the 13th of December. The trying hour produced another example of steady fidelity in Lieutenant J. S. Smith and his loyal party of Marines. Captain Fanshawe upon observing the first symptoms of revolt, ordered the detachment under arms, which was obeyed with an unsurpassed alacrity. The young but spirited Officer, who headed them, needed no prompter to a decisive conduct. He, with an unlooked for rapidity, charged bayonets, drove the guilty criminals to the larboard side of the lower deck, where, cooped up, they were forced to surrender their ringleaders.
