On 1 September 1944, Randewig was subordinated to Major-General Dr. Walter Dornberger. It was on this date that the use of V-2 rockets was ordered by SS Obergruppenführer Hans Kammler, and Randewig was ordered to the town of Kleve to join Kammler's staff. He was posted to Division 2 z b.V 1191 Signal Abteilung and dealt with signals communications within the Division as well as the special job of W/T interception within the Division. Randewig explained while under interrogation to Combined Services Detailed Interrogation Centre, that it was feared at the time that similar weapons would be used by the Allies against Germany. The special job consisted of keeping a watch on all signals which might be found to be control beams or signals for such weapons.
