This is the compelling story of the 10,000 Germans and Austrians who fled Nazi persecution and joined the British forces in their fight against Hitler during the Second World War. Known affectionately as 'the King's most loyal enemy aliens', many were Jews, but a significant number were political opponent of the Nazi regime and so-called 'degenerate artists'. With one or two exceptions, these refugees in uniform did not receive British nationality until 1946-47. At the end of the War, they returned in their thousands to Germany and Austria to begin the reconstruction of their homelands and the hunt for Nazi war criminals. Helen Fry documents the stories of those who fought for King and adopted country, drawing on a rich vein of archive material and personal accounts to bring this little-known aspect of British wartime history to light.
