Bad Wiessee is a city located in Germany.
The 30th of June, 1934, Ernst Kaufmann and other leaders of the Sturmabteilung were hosted at the Hanselbauer Hotel in Bad Wiessee. In order to gain support from the German Army for his regime, Adolf Hitler ordered the assassinations of all higher officers of the SA, in a purge that later became known as the Night of the Long Knives.
Johann Schmidt, having become Heinrich Himmler's protege, told Kauffmann that the only way the German Army would support Hitler's regime was if Kaufmann's stormtroopers were eliminated, and as Himmler and the Schutzstaffel shared Schmidt's interest in the old ways, Schmidt would take leadership of Kaufmann's weapons program.
Schmidt assasinated Kaufmann throwing a knife to his throat as the other leaders ot the Sturmabteilung were killed.
