The Battle of Möckern was a series of heavy clashes between allied Prusso-Russian troops and Napoleonic French forces south of Möckern. It occurred on 5 April 1813. It ended in a French defeat and formed the successful prelude to the "Liberation War" against Napoleon.

In view of these unexpected defeats, the French viceroy concluded on the night of 5 April to withdraw once more to Magdeburg. On its withdrawal the French forces destroyed all the bridges of the Klusdammes, denying the most important access routes to Magdeburg to the Allies. Although the French forces in Germany were not finally defeated by this action, for the Prussians and Russians the clash was nevertheless a first important success on the way to the final victory over Napoleon.
