St. Helena In October 1813, the Sixth Coalition defeated his forces at Leipzig and then invaded France. Napoleon was forced to abdicate in April of the following year and was exiled to the island of Elba. Less than a year later, he escaped to France and regained control of the government.

Napoleon spent the remaining six years of his life under British supervision on the island of St. Helena in the Atlantic Ocean
