The Battle of Lübeck took place on 6 November 1806 in Lübeck, Germany between soldiers of the Kingdom of Prussia led by Gebhard Leberecht von Blücher, who were retreating from defeat at the Battle of Jena–Auerstedt, and troops of the First French Empire under Marshals Murat, Bernadotte, and Soult, who were pursuing them. In this War of the Fourth Coalition action, the French inflicted a severe defeat on the Prussians, driving them from the neutral city. Lübeck is an old Baltic Sea port approximately 50 kilometres (31 mi) northeast of Hamburg.
