The Battle of Leipzig or Battle of the Nations, on 16–19 October 1813, was fought by the coalition armies of Russia, Prussia, Austria and Sweden against the French army of Napoleon. Napoleon's army also contained Polish and Italian troops as well as Germans from the Confederation of the Rhine. The battle involved over 600,000 soldiers, making it the largest battle in Europe prior to World War I.
Defeated, Napoleon was compelled to return to France while the Allies hurried to keep their momentum, invading France early the next year. Napoleon was forced to abdicate, and was exiled to Elba that spring.
