Historian Norman Davies describes Kunersdorf as "Prussia's greatest disaster" and the inspiration for Christian Tiedge's Elegy to "Humanity butchered by Delusion on the Altar of Blood".[47] In the Napoleonic Wars the Pomeranian town of Kolberg was besieged in 1807 (inspiring a Second World War Nazi propaganda film) while the French Grande Armée was victorious at Eylau in East Prussia in the same year. The Treaties of Tilsit were separately signed in the selfsame town in July 1807 between Napoleon and the Russians and Prussians. The Iron Cross, Germany's highest military honour, was established (though not awarded) by King Frederick William III at Breslau on 17 March 1813.[48] In World War I, Hindenburg won critical victories at Tannenberg and the Masurian Lakes, ejecting Russian forces from East Prussia.[47]
