The Battle of Leipzig
The Battle of Leipzig concludes, giving Napoleon Bonaparte one of his worst defeats.
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.

Canadians and Mohawks defeat the Americans in the Battle of Chateauguay.
The Battle of the Chateauguay was a battle of the War of 1812. On 26 October 1813, a force consisting of about 1,630 French Canadian regulars and militia and Mohawk warriors under Charles de Salaberry repulsed an American force of about 4,000 attempting to invade Canada. The Chateauguay was one of the two battles (the other being the Battle of Crysler's Farm) which caused the Americans to abandon the Saint Lawrence Campaign, their major strategic effort in the autumn of 1813.
