Prince Józef Poniatowski was the nephew of Poland's last king, a hero of the Commonwealth's last wars before its fall1, and Napoleon's most loyal Polish commander. Made a Marshal of France on the battlefield of Leipzig, he died three days later in the waters of the Elster, and became a legend.
A prince in arms
Born in Vienna in 17632, Poniatowski began his career in the Austrian army before joining the Polish army of his uncle, King Stanisław August. In the war of 1792 against Russia he won the Battle of Zieleńce on 18 June3, a victory for which the king created the order of Virtuti Militari3, still Poland's highest military decoration.

Uprising and exile
In the Kościuszko Uprising of 1794 he commanded troops in the defence of Warsaw.4 After the final partition he lived for years as a private man in Warsaw, until Napoleon's victories in 1806 opened a new chance for Poland.
The Duchy of Warsaw
As minister of war and commander-in-chief of the Duchy of Warsaw, Poniatowski built a new Polish army. In 1809, when Austria invaded, he fought the Battle of Raszyn and then struck into Austrian Galicia5, enlarging the Duchy.

Russia and Leipzig
In 1812 he led the Polish V Corps in the invasion of Russia4 and fought at Smolensk and Borodino. During the Battle of Leipzig in October 1813 Napoleon made him a Marshal of France, usually described as the only foreigner to receive that rank4 from the emperor. On 19 October, wounded and covering the French retreat, he tried to cross the swollen Elster on horseback and drowned.2

A national legend
Poniatowski was buried in Wawel Cathedral in 18176, and Bertel Thorvaldsen's equestrian statue of him stands in Warsaw. His death in the Elster, with the words about the honour of the Poles traditionally attributed to him, made him one of the great romantic heroes of Polish history.
