Background Data: During WW1, 18 vessels of varying types were acquired second hand and converted or purchased and converted while on the stocks or in a few cases building as tankers. Some were converted after serving with the Dummy Battleship Squadron by the insertion of cylindrical tanks in their holds. All were originally intended to operate as RFA’s, however owing to reasons of international law and the operation of the US Neutrality Act, these oilers became Mercantile Fleet Auxiliaries, being renamed with the LEAF nomenclature, and placed under civilian management, although operationally they remained under Admiralty control
