Jean Lannes, 1st Duc de Montebello,1st Prince de Siewierz (10 April 1769 – 31 May 1809), was a Marshal of the Empire. He was one of Napoleon's most daring and talented generals. Napoleon once commented on Lannes: "I found him a pygmy and left him a giant". A personal friend of the emperor, he was allowed to address him with the familiar "tu", as opposed to the formal "vous".
