gassing operation as it happened directly in front of him: Reporting The final part of the report describes Gerstein's attempts to circulate his eyewitness testimony. He reports on his chance encounter with the secretary of the Swedish legation in Berlin, Baron Göran von Otter, on the Warsaw-Berlin train: "Still under the immediate impression of the terrible events, I told him everything with the entreaty to inform his government and the Allies of all of this immediately because each day's delay must cost the lives of further thousands and tens of thousands". Von Otter talked with high-ranking officials at the Swedish Foreign Ministry. However, the information was not passed on to the Allies or to any other party. He also reports on his unsuccessful attempts to see the Papal Nuncio Cesare Orsenigo in Berlin. Gerstein wished to notify the Vatican. Informed of the purpose of Gerstein's visit, Orsenigo refused to meet with him. Gerstein's message was eventually sent to the Vatican not by the nuncio's office but by the auxiliary bishop of Berlin, where the information reached a "dead end". In addition to those attempts, Gerstein also stated he reported these eyewitness accounts to "hundreds of personages." Although not explicitly mentioned in the 1945 report, one of the attempts was by a Dutch industrialist, J.H. Ubbink, who in February 1943 visited Gerstein in Berlin: Ubbink passed the information on to a member of the Dutch Resistance, Cornelius Van der Hooft, who a few days later, on March 23, 1943, wrote "Tötunsanstalten in Polen" (English translation: "Killing Institutions in Poland"), a four-page report in Dutch that apparently remained hidden in the chicken coop of another member of the Dutch Resistance and did not come to light until 1996. The March report, however, seemed to have been sent to the Dutch government-in-exile, as on April 24, 1943, one month after the meeting between Van der Hooft and Ubbink, another version of the report inspired by Gerstein was written. Typed on paper without an official heading and with the simplified title of Tötungsanstalten, this version circulated within the Dutch government-in-exile via the British government and eventually to the attention of the United States Inter-Allied Information Committee. Use as evidence in trials Gerstein's report has been used as evidence in a number of high-profile cases. It was used at the Nuremberg Trials against major Nazi war criminals such as Hermann Göring and Hans Frank. It
