In the Battle of Lüneburg on 2 April 1813, Allied Russians and Prussians were victorious over a French and Saxon division. The battle was the first major combat action after the retreat of the defeated French in Russia behind the Elbe. Its importance lay in the moral effect on the German public as the first success of the Allies in the wars of liberation that were now beginning.
