The battle was fought near the town of Waterloo in present-day Belgium. The French initially gained some advantage, but the arrival of Prussian reinforcements turned the tide in favor of the coalition forces. After a day of intense fighting, the French army was eventually defeated, and Napoleon was forced to abdicate for the second time.

The Battle of Waterloo is often considered one of the bloodiest battles in history, with an estimated total of over 50,000 casualties. It marked the end of the Napoleonic era and the beginning of a period of stability in Europe, known as the Concert of Europe.

The battle had far-reaching consequences, as it led to the restoration of the Bourbon monarchy in France and the establishment of a new balance of power in Europe. It also contributed to the decline of French influence and the rise of British hegemony in the 19th century.
