Within hours, Quirnheim, Stauffenberg, Olbricht, and Werner von Haeften had been arrested, summarily tried by Colonel-General Friedrich Fromm—a quiet supporter who betrayed them once he saw the plot had failed—and taken into the courtyard of the Bendlerblock, where they were shot by a firing squad. Quirnheim was the second of the four to be shot, after Olbricht. The bodies were buried in the Matthäus Churchyard in Berlin's Schöneberg district; a stone in memory of the event stands in the churchyard. Heinrich Himmler subsequently ordered the bodies to be exhumed and cremated, and the ashes scattered.
