text_A: In 1183, the young King Henry tried again to force his father to hand over some of his patrimony. In debt and declined the control of Normandy, he tried to ambush his father at Limoges. He was joined by troops sent by his brother Geoffrey and Philip II of France. Henry II's troops besieged the town, forcing his son to flee. After wandering aimlessly through Aquitaine, Henry the Younger caught dysentery. On Saturday, 11 June 1183, the young king realized he was dying and was overcome with remorse for his sins. When his father's ring was sent to him, he begged that his father would show mercy to his mother, and that all his companions would plead with Henry to set her free. Henry II sent Thomas of Earley, Archdeacon of Wells, to break the news to Eleanor at Sarum. Eleanor reputedly had a dream in which she foresaw her son Henry's death. In 1193, she would tell Pope Celestine III that she was tortured by his memory.
