Denkmal für den unbekannten Wehrmachtsdeserteur, War memorial at Petersberg Citadel, Germany

The Denkmal für den unbekannten Wehrmachtsdeserteur stands in the fortress moat of the Petersberg Citadel, facing the Andreasviertel. Its eight metal stelae, made from scrapped heating boilers, form a narrow passage; seven stand rigidly in line, while the eighth is bent and turns away, its head tilted, as if about to leave the ranks. A bronze plaque set in the ground bears the dedication and a quotation from Günter Eich: "Seid Sand, nicht das Öl im Getriebe der Welt."

The Petersberg Citadel served as a Wehrmacht military court during World War II where soldiers faced execution for abandoning their posts. The installation was created in 1995 to commemorate those condemned to death and acknowledge their acts of dissent.

The bronze plaque set into the pavement carries the inscription "Dem unbekannten Wehrmachtsdeserteur" and a line from Günter Eich's poem Träume: "Seid Sand, nicht das Öl im Getriebe der Welt" — be sand, not the oil in the machinery of the world. The sculptor Thomas Nicolai insisted he did not want to make deserters into heroes nor the soldiers who stayed into losers.

The memorial is freely accessible in the fortress moat between the Leonhard and Philipp bastions. The location is easy to reach on foot and can be visited alongside other parts of the citadel during a single trip.

Thomas Nicolai built the eight stelae from scrap metal, specifically former heating boilers, because he wanted a material marked by wear. The steel, a medium of war, recalls the material battles of the Second World War. The narrow alley-like arrangement evokes running the gauntlet, and the pointed base edges left by the material heighten the sense of constriction.
