On the night of February 27-8, 1942 a detachment of British paratroopers landed in occupied France. Their mission: to capture a German radar site and seize the machine‘s vital parts. If they succeeded, the secrets of Germany‘s radar apparatus would be theirs-with major implications for an Allied victory. Failure was inconceivable: above all for the young British soldier who parachuted in wearing a German uniform, knowing he would have to die rather than be captured alive.
