In 1246, Henry accompanied his father on the expedition to Jaén. His father granted him in fief the first of the new conquests: Morón de la Frontera and Cote. After the fall of Seville, he was enfeoffed with more conquered towns: Jérez de la Frontera, Lebrija, Arcos and Medina Sidonia. In the "repartimiento" (division) of Seville itself, Henry and his retinue received a part. He spent the next few years mostly at Seville, often at the court of his father's second wife, Joan of Ponthieu. The troubadouric allusions to their illicit relationship are, however, of no evidentiary value.
