The battle fought off Cape St. Vincent [southern Portugal] on 14th February 1797 was not only a notable victory for the British fleet under the command of Admiral Sir John Jervis, but also the first naval engagement to bring Horatio Nelson to public attention. His considerable daring, in throwing his ship H.M.S. Captain across the path of the leading Spanish men-o'war, came at a critical moment and enabled Jervis to close up and bring the full weight of his guns upon the enemy. It was a brilliant ploy by Nelson and resulted in a shattering defeat for Spain made worse by the capture, as prizes-of-war, of four of her best vessels, San Josef and Salvador del Mundo, both 112 guns, San Nicholas - 80 guns, and San Ysidro - 74 guns. A young Lieutenant named John Miller was serving in the fleet at that time and it has been suggested that he is the author of this work.
