Mittag resided north of the district Schluft on Lake Tremmer and had there in the mid 60s, the property of the native of Argentina former Nazi Reichsbauernführer Richard Oscar Walther Darré, who had settled here in the vicinity of the second most powerful man of the Nazi dictatorship, Hermann Göring ,accepted. The National Socialist agrarian theoretician also headed the Racial and Settlement Main Office of the SS and saw the peasantry as the core of the new "master race". At noon, a two-storey house was richly decorated with antlers, in addition to a garage complex he had here a boathouse for his motorboat. His sauna was like a temple on a hill. After he had to be amputated because of a serious sugar disease, both lower legs, he had all the hunting facilities adapted for the disabled. These special constructions can still be seen in the forest between Tremmer See and Liebenthal. In addition to his property was a covered high seat within sight of a well-served feeding place, so that he got the game comfortably in front of the gun. Mittag was with Alexander Schalck -Golodkowski (head of KoKo and Secretary of State in the GDR Foreign Trade Ministry) a respected partner of politicians and business managers of the Old West Germany. Since Schalck-Golodkowski had settled only a few kilometers away at the Gollinsee, the two of them did not only talk about the hunt in the Schorfheide, but also started many a project, such as the multi-billion loan, the Franz-Josef Strauß in the early 80s Granted years of the GDR and thus allowed the continuation of the socio-political achievements of the GDR to its citizens. Above all, however, Schalck-Golodkowski provided Günter Mittag with western products right up to Selterswasser, as he increasingly refused, according to statements by his staff, to take GDR products.
