The Explorers' Club, № DXCI

The Dreadnought Hoax—In February 1910, led by Horace de Vere Cole & Adrian Stephens, a gang of pranksters (a forerunner of the later Bloomsbury Group), theatrically disguised themselves as "Abyssinian princes" (Ethiopian royalty) & bluffed their way onto the battleship H.M.S. Dreadnought, the Royal Navy's flagship, where they were formally greeted as foreign dignitaries.
