This is popular WW2 history at its heart-stopping best, fuelled by an incredible new story During WW2, a group of Jewish refugees (intellectuals, writers, artists and athletes - most from Germany and Austria) escaped to Britain and were interned as 'enemy aliens'. In 1942, they were selected and trained to form a special unit of commandoes who would be sent back into Europe to play a significant role in the final battles against the Nazis. Based on original archival research, interviews and a cache of newly discovered sources, this is a book brimming with camaraderie, heroism and high-octane storytelling, as it tells the dramatic story of the X-Troop men who helped to defeat the Nazis and liberate the concentration camps where their families had either been killed or imprisoned.
