Jean Lannes, 1st Duc de Montebello, (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 as "tu", as opposed to "vous".
Lannes was born in the small town of Lectoure, in the Gers department in the south of France. He was the son of a Gascon farmer, Jeannet Lannes (1733 – 1812, son of Jean Lannes (d. 1746) and wife Jeanne Pomiès (d. 1770) and paternal grandson of Pierre Lane and wife Bernarde Escossio, both died in 1721), and wife Cécile Fouraignan (1741 – 1799), and was apprenticed to a dyer. He had little education, but his great strength and proficiency in all manly sports caused him in 1792 to be elected sergeant-major of the battalion of volunteers of Gers, which he had joined on the breaking out of war between Spain and the French republic. He served through the campaigns in the Pyrenees in 1793 and 1794, and rose by distinguished conduct to the rank of chef de brigade. However, in 1795, on the reform of the army introduced by the Thermidorians, he was dismissed from his rank.
