The 357th Fighter Group was an air combat unit of the United States Army Air Forces during the Second World War. The 357th operated P-51 Mustang aircraft as part of the U.S. Eighth Air Force and its members were known unofficially as "The Yoxford Boys" after a village near their base in the UK. (Group tradition holds that the name was the invention of Lord Haw Haw in a broadcast greeting the night of its arrival at RAF Leiston.) Its victory totals in air-to-air combat are the most of any P-51 group in the Eighth Air Force and third among all groups fighting in Europe.
