The Kleinmachnow Tunnel and the Arrest of Harry Seidel

The betrayal of a 70-metre tunnel into Kleinmachnow ended with the capture of the famous escape helper Harry Seidel, who was sentenced to life imprisonment in a show trial.

In October and November 1962 the brothers Boris and Eduard Franzke and three other helpers dug a tunnel from a building site near Neuruppiner Straße in Zehlendorf towards the house at Wolfswerder 29 in Kleinmachnow, on GDR territory. At about 70 metres it was the longest tunnel they had dug. Harry Seidel, a former cyclist and one of the most active escape helpers, joined in early November.

Under time pressure the breakthrough was made on 14 November 1962 before the house was reached. Seidel volunteered to climb out into the garden and fetch the refugees. The Stasi had been informed and was waiting: Seidel was seized, but managed to shout a warning so the others could retreat through the tunnel. An explosive charge laid along the tunnel route failed to go off because its cables had been cut.

Six weeks later Seidel stood trial before the GDR Supreme Court and on 29 December 1962 was sentenced to life imprisonment. In 1966 the Federal Republic bought his release. Who betrayed the tunnel remains unclear.
