Other documents set forth that from time to time the temperature of the water would be lowered by 10° Centigrade and a quart of blood would be taken from an artery in the subject’s throat for analysis. The organs of the victims who died were extracted and sent to the Pathological Institute at Munich.
Rewarming of the subjects was attempted by various means, most commonly and successfully in a very hot bath. In September, Himmler personally ordered that rewarming by the warmth of human bodies also be attempted, and the inhuman villains who conducted these experiments promptly produced four gypsy women from the Ravensbrueck concentration camp. When the women had arrived, rewarming was attempted by placing the chilled victim between two naked women.
A voluminous report on the freezing experiments conducted in tanks of ice water, written in October 1942, contains the following (NO-428):
“If the experimental subject were placed in the water under narcosis, one observed a certain arousing effect. The subject began to groan and made some defensive movements. In a few cases, a state of excitation developed. This was especially severe in the cooling of the head and neck. But never was a complete cessation of the narcosis observed. The defensive movements ceased after about 5 minutes. There followed a progressive rigor, which developed especially strongly in the arm musculature; the arms were strongly flexed and pressed to the body. The rigor increased with the continuation of the cooling, now and then interrupted by tonic-clonic twitching. With still more marked sinking of the body temperature, it suddenly ceased. These cases ended fatally, without any successful results from resuscitation efforts.
“Experiments without narcosis showed no essential differences in the course of cooling. Upon entry into the water, a severe cold shuddering appeared. The cooling of the neck and back of the head was felt as especially painful, but already after 5 to 10 minutes, a significant weakening of the pain sensation was observable. Rigor developed after this time in the same manner as under narcosis, likewise the tonic-clonic twitchings. At this point, speech became difficult because the rigor also affected the speech musculature.
“Simultaneously with the rigor, a severe difficulty in breathing set in with or without narcosis. It was reported that, so to speak, an iron ring was placed about the chest. Objectively, already at the beginning of this breathing difficulty, a marked dilatation of the nostrils occurred. The expiration was prolonged and visibly difficult. This difficulty passed over into a rattling and snoring breathing. * * *” [Emphasis not shown.]
During the winter of 1942 and 1943, experiments with “dry” cold were conducted. And Rascher reported on these in another letter to Himmler (1616-PS):
“Up to now, I have cooled off about 30 people stripped in the open air during nine to fourteen hours at 27° to 29°. After a time, corresponding to a trip of 1 hour, I put these subjects in a hot bath. Up to now, every single patient was completely warmed up within 1 hour at most, although some of them had their hands and feet frozen white.”
The responsibility among the defendants for the freezing experiments is substantially the same as for the high-altitude tests. The results were, if anything, ever more widely known in German medical circles. In October 1942, a medical conference took place here in Nuernberg at the Deutscher Hof Hotel, at which one of the authors of the report from which I have just quoted spoke on the subject “Prevention and Treatment of Freezing”, and the defendant Weltz spoke on the subject “Warming up after Freezing to the Danger Point.” Numerous documents which we will introduce show the widespread responsibility among the defendants, and in the highest quarters of the German Air Force, for these sickening crimes.
