Emperor Napoleon arrives at Portoferraio on the island of Elba to begin his exile.

Napoleon Bonaparte, later known by his regnal name Napoleon I, was a French general and statesman who rose to prominence during the French Revolution and led a series of military campaigns across Europe during the French Revolutionary and Napoleonic Wars from 1796 to 1815. He led the French Republic as First Consul from 1799 to 1804, then ruled the French Empire as Emperor of the French from 1804 to 1814, and briefly again in 1815. He was King of Italy from 1805 to 1814 and Protector of the Confederation of the Rhine from 1806 to 1813.

Portoferraio is a town and comune in the province of Livorno, on the edge of the eponymous harbour of the island of Elba, Tuscany. It is the island's largest town. Because of its terrain, many of its buildings are situated on the slopes of a tiny hill bordered on three sides by the sea.

Elba is a Mediterranean island in Tuscany, Italy, 10 km (6.2 mi) from the coastal town of Piombino on the Italian mainland, and the largest island of the Tuscan Archipelago. It is also part of the Arcipelago Toscano National Park, and the third largest island in Italy, after Sicily and Sardinia. It is located in the Tyrrhenian Sea about 50 km (30 mi) east of the French island of Corsica.
