Bertrand de Poulengy, known in Age of Empires II: The Age of Kings as Sieur Bertrand, was a French soldier in the Hundred Years' War. He and his companion Jean de Metz are best known for escorting Joan of Arc from Vaucouleurs to Chinon in 1429. They appear in the scenario An Unlikely Messiah, and are also available in the Scenario Editor. Sieur Bertrand has the appearance of a Knight, but he has slightly better combat stats. As a hero, he regenerates his health, making him very valuable in the scenario.
