This text is a talk read on occasion of the setting of a commemorative stepping stone for Oskar Voss, an electrical welder at the Hamburg shipyard of the ‘Howaldtswerke’ who was beheaded by the Nazis in 1944. A member of the worker resistance to fascism he directly sabotaged the construction of Nazi submarines. The author draws a line between the oft-neglected worker resistance to Nazism, the solidarity shown to US soldiers fleeing the Vietnam war, the sabotage of a war boat for the Portuguese marine still under Salazar’s grip, the work stoppage on the shipyard of ‘Blohm & Voß’ protesting the war against Iraq in 1990 and finishes with a call to sabotage armament production and to resist militarisation.
