The Shetland Bus was not a bus, but the nickname of a special operations group that set up a route across the North Sea between Norway and the Shetland Islands, north-east of mainland Scotland. The first voyage was made by Norwegian sailors to help their compatriots in occupied Norway, but soon the Secret Intelligence Service and the Special Operations Executive asked if they would be prepared to carry cargoes of British agents and equipment, as well. Fourteen boats of different sizes were originally used, and Flemington House in Shetland was commandeered as the operation's HQ. The first official journey was carried out by the Norwegian fishing vessel the Aksel, which left Luna Ness on 30 August 1941 on route to Bremen in Norway. This book examines that first journey, as well later ones, and discusses the agents and operations which members of the Shetland Bus were involved in throughout the war.
