Alexis von Roenne

Historian Ben Macintyre's 2010 book Operation Mincemeat, provides additional specifics about the involvement of von Roenne in the ruse played on the Germans during the Second World War by the British. Forged "documents" claimed that the Allies would invade Greece and Sardinia before the invasion of Sicily, leading Germany to divert important assets to that area. The Baron was said to have vouched for the authenticity of the documents and also accepted other hoaxes used by the Allies during the war.

Arrested in the immediate aftermath of the 20 July plot, because of his connection with several of those responsible, but released shortly afterwards, von Roenne was rearrested on 9 August and tried before Roland Freisler's People's Court on 5 October. Declaring that Nazi race policies were inconsistent with his Christian values, he was found guilty by the show trial and hanged on a meat hook at Plötzensee Prison on 12 October 1944. His final epitaph to his wife, Ursula von Bülow, reflected his faith, stating "in a moment now I shall be going home to our Lord in complete calm and in the certainty of salvation".

Alexis Freiherr von Rönne (22 February 1903 – 12 October 1944) was a German Army colonel and senior intelligence analyst. He became one of Hitler's favoured officers in the Abwehr, despite secretly being of anti-Nazi persuasion.
