Some captured German and Austrian personnel were brought to Britain as prisoners of war. Those who were identified as anti-Nazi were 'turned' and, codenamed 'Bonzos', were trained in paramilitary and clandestine warfare to be sent back into occupied Europe on top secret missions. The British Special Operations Executive arranged the infiltration of four Austrians, Albrecht Gaiswinkler, Joseph Grafl, Karl Standhartinger and Karl Lzicar, into the Salzkammergut area of northwestern Austria. This book tells the story of Operation EBENSBURG, their mission to kidnap or assassinate Joseph Goebbels, the Reich's Minister of Propaganda, to organise resistance groups before the arrival of American forces and to protect the looted works of art hidden in the Altaussee salt mine.
