Wiesbaden as the advancing U.S. Army crossed the Rhine bridgeheads. Upon his arrival in Pottenstein, Bavaria, Stroop received word Himmler wished to meet him in Berlin. On 14 April, Stroop met Himmler in his private train near Prenzlau. With a pass signed by Himmler, Stroop traveled to the Alpine Redoubt with a group of teenaged Hitler Youth members he was training for war. To obtain gasoline and other scarce supplies, Stroop showed Himmler's signed order and claimed to be transporting his Werwolf unit to build an Alpine bastion for the salvation of the Reich. However, after a secret conference at Taxenbach, Austria, Stroop and his fellow Werwolf commanders decided to change into Wehrmacht uniforms and surrender to the Western Allies.

In conversation with Moczarski, Stroop lamented, "Nearly all of those judges were Jews or Freemasons. I studied them very closely. Most of them had dark hair." He further lamented one of his U.S. Army defense lawyers was wearing a Masonic ring in court. According to Gustav Schielke, his cellmate: Stroop behaved like a swine in the dock. He acted innocent as a lamb, pretending the killings were news to him. Because of his incriminations, several fellow defendants were sentenced to
