Pierre-Charles Villeneuve (1763-1806) was a French Admiral during the Napoleonic Wars notable for his command of the French and Spanish fleets defeated by Horatio Nelson and the British fleet at the Battle of Trafalgar.
Villeneuve was born in 1763, and joined the French navy in 1778. He served during several battles, including the Battle of the Nile, and was promoted to rear-admiral as a result of this. When Villeneuve returned to Europe, he was captured when the British captured the island of Malta, but was soon released.
In 1804, Napoleon Bonaparte, the Emperor of France, ordered Villeneuve, now a vice-admiral, to draw the British fleet away from the English Channel and the return to assist with a planned invasion. All went as planned, but Villeneuve and the Combined Fleets ran into Nelson off the shore of Cape Trafalgar, near Cadiz. Nelson, though outnumbered, won the battle, and Villeneuve's ship, the Redoubtable, was captured.
Villeneuve himself was sent to England, but was released on parole. He returned to France in 1806, despairing over his loss at Trafalgar, and took his own life.
