Following the war, Gersdorff participated in the work of the
U.S. Army Historical Division, in which, under the guidance of
Franz Halder, German generals wrote
World War II operational studies for the
U.S. Army, first as
POWs and then as employees. In the late 1940s, Gersdorff authored an operational study on the Wehrmacht response to the
Allied Normandy breakout. (The study, together with contributions from
Paul Hausser,
Heinrich Freiherr von Lüttwitz,
Wilhelm Fahrmbacher and
Heinrich Eberbach, was published in 2004 as
Fighting the Breakout: The German Army in Normandy from COBRA to the Falaise Gap). In the mid-1950s, Gersdorff tried to join the
Bundeswehr, the armed forces of postwar
West Germany. Despite his distinguished record and decorations, his attempts were, according to Gersdorff, opposed by
Hans Globke, the powerful
head of the German Chancellery and confidant of
Chancellor Konrad Adenauer, and by various former Wehrmacht officers in the
Bundeswehr who did not want a "traitor" in their midst. He thus was prevented from resuming his military career. Gersdorff later dedicated his life to charity in the
Order of St. John. He was a founding president of the
Johanniter-Unfall-Hilfe, which he chaired from 1952 to 1963. In 1979 he was awarded the
Großes Verdienstkreuz (Grand Cross of Merit), one of the eight classes of West Germany's only
state decoration, in recognition of his accomplishments. A riding accident in 1967 left Gersdorff
paraplegic for the last twelve years of his life, during which he wrote and published his memoirs, . In his memoirs, Gersdorff claimed to have opposed the OKW's
Commissar Order and other "criminal orders". This was shown to be false by the historian Joannes Huerter, of the
Munich Institute for Contemporary History. Huerter also found that "Tresckow and his circle were by no means fundamentally opposed to Hitler's decision to attack the Soviet Union, and that they were well informed of and collaborative in the earliest mass murders of Jewish civilians", as many officers in the Army Group Center were aligned with
National Socialist Ideology with its
anti-communism and
anti-Semitism. Huerter states that many of the officers of that group of conspirators in particular, believed that these crimes against humanity still in the initial stages would appear "less horrific when weighed against the chance to strike at the heart of the Soviet Union and only when it became apparent that the military risk had not paid off and the mass murders took on genocidal dimension did ethical second thoughts come to play a role for the young staff officers of the Army Group Center". The memoirs were influential in shaping the post-war discourse on the German military resistance and included many of the "myth-building statements" that fed much later works on the subject. Gersdorff died in
Munich,
Bavaria, in 1980, at the age of 74. ==Works==
