Based on my report that, as proposed by the Reich Leader SS, there is a good possibility for carrying out our military scientific research work in the Natzweiler concentration camp, I hereby summarize what awaits your approval:
1. Information to the commander’s office, Natzweiler concentration camp: SS Hauptsturmfuehrer Professor Dr. Hirt, Stabsarzt Dr. Wimmer, and Dr. Kieselbach are authorized to enter the Natzweiler concentration camp. During their activity in the Natzweiler concentration camp, they are to be provided with accommodations and board.
2. SS Oberscharfuehrer Walbert, at present supply sergeant in the administration of the Natzweiler concentration camp, is to be detached for service with the Institute for Military Scientific Research, Personal Staff Reich Leader SS, Strasbourg-Natzweiler section. Walbert will have to tend the animals under the supervision of SS Hauptsturmfuehrer Professor Dr. Hirt. It is requested that another man be assigned to the administration of the Natzweiler concentration camp in order to replace SS Oberscharfuehrer Walbert.
3. The transfer of two prisoners from the group which has been trained on the microtome for pathological research in the Buchenwald concentration camp is requested.
4. It is furthermore requested, that a younger physician be assigned to assist the camp medical officer, SS Hauptsturmfuehrer Dr. Blanke, in the Natzweiler concentration camp.
5. The experiments which are to be performed on prisoners are to be carried out in four rooms of an already existing medical barrack. Only slight changes in the construction of the building are required, in particular the installation of the hood which can be produced with very little material. In accordance with attached plan of the construction management at Natzweiler, I request that necessary orders be issued to same to carry out the reconstruction.
6. All the expenses arising out of our activity at Natzweiler will be covered by this office. I have already discussed the accounting procedure with the administrative leader, SS Obersturmfuehrer Faschingbauer.
In conclusion I would be very grateful to you, my dear Brigadefuehrer, if you would inform the commander of the Natzweiler concentration camp, that you have approved the execution of the work at Natzweiler, just as it was discussed with me there, and about which I reported to you in detail, and that you desire that we be given assistance in fulfilling the duties with which we have been entrusted by the Reich Leader SS.
Heil Hitler!
