“In the middle of May 1941, as far as I remember, the Chief of Amt 4 of the RSHA (SS-Brigadefuehrer Mueller), in the name of the Chief of the RSHA (SS-Gruppenfuehrer Heydrich), held discussions with the Generalquartiermeister of the Army (General Wagner) about questions connected with the operations of the SIPO and SD within the bounds of the Field Army during the imminent campaign against Russia. Wagner could come to no agreement with Mueller and therefore asked Heydrich to send another representative. I was at that time Chief of Section E in Amt 4 of the RSHA under Chief of Amt Mueller and was sent by Heydrich to Wagner because of my experience in matters of protocol for the purpose of drawing up the final agreement. According to the instructions given to me, I was supposed to make sure that this agreement would provide that the responsible headquarters in the Army would be firmly obligated to give complete support to all activities of the Combat Groups and Combat Commandos of the SIPO and SD. I discussed the problem of this mutual relationship in great detail with Wagner. In accordance with this discussion I then presented him with the completed draft of an agreement, which met with his full approval. This draft of an agreement was the basis for a final discussion between Wagner and Heydrich towards the end of May 1941.
“The contents of this agreement, as far as I remember, were substantially as follows. Its basis was the Fuehrer’s command, mentioned at the very beginning of the agreement, that the SIPO and SD should operate within the combat elements of the Field Army, with the mission of utterly smashing all resistance in conquered front-line areas as well as in conquered rear supply zones by every means and as quickly as possible. The various areas were then set down in which the SIPO and SD were to be active and operating. The individual Combat Groups were then assigned to the army groups which were to take part in the campaign and the individual Combat Commandos to the respective armies which were to take part in the campaign.
“The Combat Groups and Combat Commandos were to operate in detail:
“1. In front-line areas: in complete subordination to the Field Army, tactically, functionally and administratively;
“2. In rear operational areas: in merely administrative subordination to the Field Army, but under command and functional control of the RSHA;
“3. In rear Army areas: arrangement as in 2;
“4. In areas of the civil administration in the East: same as in the Reich.
“The tactical and functional authority and responsibility of front-line headquarters of the Field Army over the Combat Commandos found no limitation in the agreement and therefore needed no further clarification.
“The agreement made it clear that the administrative subordination embraced not only disciplinary subordination but also the obligation for rear headquarters of the Field Army to support the Combat Groups and Combat Commandos in matters of supply (gasoline, rations, etc.) as well as in the use of the communications network.
“This agreement was signed by Heydrich and Wagner in my presence. Wagner signed it either ‘acting for’ or ‘by order of’ the OKH.
