Many thanks, Asergeant, this is a wonderful and very moving testimony, broadcasted in 1964. The interviewed man, who speaks an impeccable French and has a real talent for telling stories, was one of those soldiers who witnessed Peguy's death. After both higher officers of the company were killed in less than 30 minutes, Leutnant Peguy decided to take the lead and stood up against machine gun fire, exhorting his men to progress, although they were begging him to lay down and protect himself. This is when he was shot in the head. The man confirms that his last words before he died were "Mon Dieu, mes enfants" (my God, my children), something I have often read about Peguy's death.
By the way I made a mistake in my first post. The hill occupied by the Germans toward which the French were moving is Monthyon, not Villeroy. Villeroy is another village nearby.
