In the night of September 7-8, 1943, six prisoners whose execution had not been ordered at all are also "accidentally" hanged. Reich Justice Minister Otto Thierack learns of the atrocious matter shortly thereafter. He has it covered up and orders the mass executions to continue.

After pausing for only 12 hours, the executioners in Plötzensee hang over 60 more victims during the following nights until September 12, 1943. Over 250 people are murdered between September 7 and 12, 1943, among them German, French, and especially Czech prisoners.
