not want to know the backgrounds of the men that the BND hired in the 1950s. The American National Security Archive states that "he employed numerous former Nazis and known war criminals". On the other hand, Gehlen himself was cleared by James H. Critchfield of the Central Intelligence Agency who worked with the Gehlen Organization from 1949 to 1956. In 2001, he said that "almost everything negative that has been written about Gehlen, [as an] ardent ex-Nazi, one of Hitler's war criminals ... is all far from the fact," as quoted in The Washington Post. Critchfield added that Gehlen hired former Sicherheitsdienst (Security Service of the Reichsführer-SS) men "reluctantly, under pressure from German Chancellor Konrad Adenauer to deal with 'the avalanche of subversion hitting them from East Germany'" From 2011 to 2018, an independent commission of historians studied the history of the BND in the era of Reinhard Gehlen. The results are published in comprehensive studies. So far (as of April 2020) eleven volumes have been published. Operations 1960s During the first years of oversight by the State Secretary in the federal chancellery of Konrad Adenauer of the operation in Pullach, Munich District, Bavaria, the BND continued the ways of its forebear, the Gehlen Organization. The BND racked up its initial east–west cold war successes by concentrating on East Germany. The BND's reach encompassed the highest political and military levels of the GDR regime. They knew the carrying capacity of every bridge, the bed count of every hospital, the length of every airfield, the width and level of maintenance of the roads that Soviet armor and infantry divisions would have to traverse in a potential attack on the West. Almost every sphere of eastern life was known to the BND. Unsung analysts at Pullach, with their contacts in the East, figuratively functioned as flies on the wall in ministries and military conferences. When the Soviet KGB suspected an East German army intelligence officer, a lieutenant colonel and BND agent, of spying, the Soviets investigated and shadowed him. The BND was positioned and able to inject forged reports implying that the loose spy was actually the KGB investigator, who was then arrested by the Soviets and shipped off to Moscow. Not knowing how long the caper would stay under wraps, the real spy was told to be ready for recall; he made his move to the West at the appropriate time.
