June 1942. The Third Reich is victorious everywhere. In desperation, Winston Churchill and his chief of staff form an unusual plan: a new commando unit made up of Jewish refugees from Germany and Austria who escaped to Britain just before the War. Many have lost their families, their homes - their whole worlds. And now, in the crucial final battles against the Nazis, they will stop at nothing to defeat them. Trained in counterintelligence and advanced combat, this top secret unit becomes known as X Troop. Some simply call them a suicide squad. Drawing on extensive original research, including interviews with the last surviving members, Leah Garrett follows this unique band of brothers from Europe to England and back again, with stops at British internment camps, the beaches of Normandy, the battlefields of Italy and Holland, and the hellscape of Terezin concentration camp.
