When it was clear that the coup had failed, the less resolute members of the conspiracy in Berlin began to change sides. Fromm was freed from his detention room and, after a brief fight, he managed to regain control of the Bendlerblock. In a desperate attempt to cover his involvement, he ordered the executions of General Friedrich Olbricht, his chief of staff Colonel Albrecht Mertz von Quirnheim, Colonel Claus von Stauffenberg and his adjutant Lieutenant Werner von Haeften. Shortly after midnight, the condemned men were led to a mound of earth back-lit by idling vehicles where each was executed by firing squad in the courtyard of Bendlerstraße headquarters, the street has been renamed Stauffenbergstraße in honour of Colonel Stauffenberg. Further executions were forbidden following the arrival of Waffen-SS personnel under the command of "Obersturmbannfüher" Otto Skorzeny.
