Freezing experiments were carried out at Dachau concentration camp for the benefit of the Luftwaffe, during the year 1942. Details of these experiments are discussed elsewhere in this judgment. It is conclusively shown from the evidence dealing with freezing that as early as the year 1943 Schroeder had actual knowledge that such experiments had been conducted upon inmates at Dachau concentration camp, during the course of which suffering and deaths had resulted to the experimental subjects. TYPHUS EXPERIMENTS Experiments in connection with typhus were conducted at Schirmeck and Natzweiler concentration camps during the years 1942, 1943, and 1944. The details of these experiments are discussed elsewhere in this judgment. The experiments were carried out by a Luftwaffe medical officer, Professor Dr. Haagen. As a medical officer of the Luftwaffe he was subject to Schroeder’s orders after the latter became Chief of the Medical Service of the Luftwaffe. The office of Schroeder issued and approved the research assignments pursuant to which these experiments were carried out. It provided the funds for the research. One of the chief collaborators in the program was the defendant Rose, consultant to the Chief of the Medical Service of the Luftwaffe. Correspondence was carried on between Haagen and the Chief of Staff for the defendant Schroeder with reference to whether a typhus epidemic prevailing at Natzweiler was connected in any manner with the vaccine research then being conducted. The office of the Chief of the Medical Service of the Luftwaffe received reports on the experiments from which it could be clearly perceived that typhus vaccine experiments were being performed on concentration camp inmates. While the experiments were in progress, Schroeder admits having visited Haagen at Strasbourg, but denies that he talked with Haagen about the experiments. The defendant’s assertion that the experiments were not discussed does not carry conviction. As has been pointed out in this judgment, the law of war imposes on a military officer in a position of command an affirmative duty to take such steps as are within his power and appropriate to the circumstances to control those under his command for the prevention of acts which are violations of the law of war.
