Britain's Enemy Aliens, Nazi War Criminals and the Reconstruction of Post-War Europe. Thousands of Germans and Austrians fled Nazi persecution and served with British forces during the Second World War. At the end of the conflict, many returned with the Intelligence Corps and Military Government, to rebuild their countries. Some were involved with the hunt for Nazi war criminals; some re-educated people about democracy and a free society. Based on first-hand accounts from veterans, this book provides an important insight into how Germany and Austria were rebuilt after the end of the Nazi tyranny.
