damage to their health by the gas which eventually would escape. I should like to take this opportunity to bring the following to your attention: Several commands have had the unloading, after the application of gas, done by their own men. I brought to the attention of the commanders of these special detachments concerned the immense psychological injury and damage to their health which that work can have for those men, even if not immediately, at least later on. The men complained to me about headaches which appeared after each unloading. Nevertheless they don't want to change the orders, because they are afraid prisoners called for that work could use an opportune moment to flee. To protect the men from such damage, I request orders be issued accordingly. The application of gas usually is not undertaken correctly. In order to come to an end as fast as possible, the driver presses the accelerator to the fullest extent.

Distorted faces and excretions, such as could be seen before, are no longer noticed.

"The three S-vans which are there are not sufficient for that purpose. I request assignment of another S-van (5 tons). At the same time I request the shipment of 20 gas hoses for the three S-vans on hand (two-Diamond, one Saurer), since the ones on hand are leaky already. " —Signed — " the Commandant of the Security Police and the Security Service, Ostland."
It would appear from the documentary evidence that a certain amount of discord existed between the officials of the German Government as to the proper means and methods used in connection with the program of extermination. A secret report dated 18 June 1943, addressed to Defendant Rosenberg, complained that 5,000 Jews
