The Dreadnought hoax was a practical joke pulled by Horace de Vere Cole in 1910. Cole tricked the Royal Navy into showing their flagship, the warship HMS Dreadnought, to a supposed delegation of Abyssinian royals. The hoax drew attention in Britain to the emergence of the Bloomsbury Group, among whom some of Cole's collaborators numbered. The hoax was a repeat of a similar impersonation which Cole and Adrian Stephen had organised while they were students at Cambridge in 1905.
