A revealing study of Reinhard Gehlen's rise from Nazi intelligence to Cold War spymaster for the West.

Eleven years after Reinhard Gehlen, the head of Adolf Hitler's Eastern Front military intelligence unit, emerged from hiding to hand himself over to US forces, he had, with the help of the American CIA, created a legend for himself as founder and first president of the West German Secret Service. In this role he employed many of the same Wehrmacht and SS officers he had served with during the Second World War.

All through the steady progression of his career before and during the Second World War, Gehlen had been far too industrious and committed to court the limelight. Then after the defeat of Germany, when he transferred his allegiance to the CIA and later became head of the Bundesnachrichtendienst, he became a man whom Hugh Trevor Roper's described as someone who 'always moved in the shadows'.

For some, the German intelligence network that Gehlen had controlled since 1942, was part of an unbroken tradition going back to the days of Bismarck. For a great many in Gehlen's organisation the Cold War was merely an extension of an anti-Soviet campaign that had begun on 22 June 1941, when Hitler launched Operation Barbarossa.

After the war, Gehlen had emerged unscathed from Hitler's bunker and no war crimes charges were ever brought against him. His name, and those of 350 of his Wehrmacht command, were redacted from the official lists of German prisoners of war. Gehlen protected and employed men like Heinrich Schmitz who had been part of Einsatzgruppe A, the murder squad that massacred so many, including communist functionaries and Jewish women, men and children, in the Baltic States.

Though Gehlen had remained loyal to Hitler right to the end, once state authority collapsed he wasted little time in making contact with the Americans and offered to place his vast intelligence resources at their disposal in the new fight against Soviet communism. While German generals Heinz Guderian and Franz Halder placed great store by Gehlen's reports on the tactical level, Hitler called them 'defeatist' and gave them barely a glance when making his disastrous strategic decisions. Allen Dulles, head of the CIA, did not repeat Hitler's mistake, but Gehlen deeply resented the way that his reports to Dulles were mishandled.

It became Gehlen's ambition initially to head up a completely independent West German foreign intelligence service
