'Code Name Nimrod' is the story of one man’s involvement in one of World War II’s greatest deceptions. He was a member of a secret organization formed by Earl Mountbatten called “X-troop”. Mountbatten needed men who could speak colloquial German, read German documents and interrogate German prisoners. They must also understand German psychology, so he suggested to Mr. Churchill that he should form a Troop of anti-Nazi German, Hungarian and Austrian volunteers. They were all technically enemy aliens and understandably, were almost all Jewish.
