Janko responded by offering to set up a regiment of about 3,000 local ethnic Germans, with limited service interaction with the Wehrmacht and Waffen-SS. In April 1942, Himmler created the 7th SS Volunteer Mountain Division Prinz Eugen and began to conscript Volksdeutsche from Banat and Romania. In his book (referenced below) Sepp Janko bragged about his ability to recruit sons of ethnic Germans from Banat region. This excerpt was used in Nuremberg war crimes trial in May 1946:  “ … I put at the disposal of the Fuehrer almost the entire German national group in the former State of Yugoslavia and gave him so many volunteers as soldiers, is to me a subject of great pride." The Division was based in Banat but served across former Yugoslavia. "The Waffen SS immediately enlisted 600 "Volksdeutsche", and in July it announced plans for the formation of an exclusively German regiment. But in the Banat the SS encountered competition from the Wehrmacht, which had in mind sponsoring its own unit, a militia force of some 8,000 men. Himmler, alarmed by this development, took the case to Hitler and secured permission not only to create a new, exclusively "Volksdeutsche" SS division but also to take over the Wehrmacht's militia." Janko was able to escape the National Liberation Army (Yugoslavia) in late 1944 to Austria, where he was arrested by United States forces and taken to the Wolfsberg camp in Carinthia. He was interned with the Nazi ambassador in Independent State of Croatia (Siegfried Kasche) and the German minority leader in Croatia (Branimir Altgayer). Both of the latter were delivered by the British to Tito and executed, but Janko managed to flee internment to Italy before his extradition from the camp. In 1951 he fled to Argentina with a pass from the Red Cross, issued in the name of José Petri. (José stands for Joseph; Petri was his wife's maiden name. He had married Leni Petri in 1936 in a church wedding.) Janko was indicted by the Yugoslav government for war crimes. At the instigation of the Yugoslav government, he was arrested and imprisoned until his extradition. Due to intervention by President Juan Perón, Janko was released. He remained in Belgrano, Buenos Aires until his death in 2001, aged 95.
