The actual date of the commencement of the experiments at Dachau was 22 February 1942, which was recalled by the witness Neff because it was his birthday. (_Tr. p. 606._) From this point on, the defendant Weltz takes the position that he had no knowledge of the work and that, in fact, Rascher was relieved from his command. Weltz admitted that it was his obligation to supervise Rascher and that the existing arrangement between Ruff and Weltz was that this was to be a joint undertaking. Ruff exercised supervision over Romberg, and Weltz was to exercise supervision over Rascher. Weltz conceded that he was Rascher’s disciplinary superior and was responsible for the scientific programs to which he assigned Rascher. (_Tr. p. 7088._) Despite this chain of command and working agreement, Weltz takes the position that Rascher endeavored to work independently and that he did not desire to report to Weltz. (_Tr. pp. 7088-9._) It became necessary for Weltz to order Rascher to report to him twice a week and, as a result of this order, Weltz alleges that Rascher came to him in the middle of February and that they had their first conversation since the meeting in Dachau and on that occasion, Rascher informed Weltz that the experiments had not even started yet and that he had nothing to report. (_Tr. p. 7089._) Weltz testified that Anthony, under whom Becker-Freyseng worked in the Luftwaffe Medical Inspectorate, in Berlin, telephoned him to inquire how the Dachau experiments were progressing and that he could only reply that nothing had been reported to him. Rascher reported to him for the second time, whereupon Weltz informed Rascher that a telephone call had come through from Berlin and that he wanted to have some clarification as to how things stood at Dachau. Rascher did not want to report anything to Weltz at the second conversation, and Weltz maintains that he told Rascher that he was going to Berlin to clear up the situation and obtain a clear decision whether or not Rascher was to report to him. Then, on the occasion of the third visit from Rascher, Weltz, expecting a sharp argument, asked Wendt of his office to come into the room, and on that occasion he confronted Rascher with the alternative either to report to him or to leave the institute. Weltz asserts that at that time Rascher showed him a telegram from Himmler, which read: “Experiments are to be kept secret from everyone.” (_Tr. p. 7089._) Thereupon, Weltz maintains that he ordered Rascher from his institute and that he then composed a letter, together with Wendt, to the Luftgau and asked for Rascher’s immediate transfer and that within a few days Rascher’s assignment had ended.
