von Braun were aware of everything daily. As they went along the corridors, they saw the exhaustion of the inmates, their arduous work and their pain. Not one single time did Prof. Wernher von Braun protest against this cruelty during his frequent stays at Dora. Even the aspect of corpses did not touch him: On a small area near the ambulance shed, inmates tortured to death by slave labor and the terror of the overseers were piling up daily. But, Prof. Wernher von Braun passed them so close that he was almost touching the corpses. Von Braun later claimed that he was aware of the treatment of prisoners, but felt helpless to change the situation.

To increase his power-base within the Nazi regime, Himmler was conspiring to use Kammler to gain control of all German armament programs, including the V-2 program at Peenemünde.

A young female dentist who was an SS spy reported their comments. Combined with Himmler's false charges that von Braun and his colleagues were communist sympathizers and had attempted to sabotage the V-2 program, and considering that von Braun regularly piloted his government-provided airplane that might allow him to escape to Britain, this led to their arrest by the Gestapo. The unsuspecting von Braun was detained on 14 March (or 15 March), 1944, and was taken to a Gestapo cell in Stettin (now Szczecin, Poland). where he was held for two weeks without knowing the charges against him. Through Major Hans Georg Klamroth, in charge of the Abwehr for Peenemünde, Dornberger obtained von
