to subdue the army and then followed the defenders inside the open gates, where he easily took over the castle in two days. Richard the Lionheart's victory at Taillebourg deterred many barons from thinking of rebelling and forced them to declare their loyalty to him. In 1181–82, Richard faced a revolt over the succession to the county of Angoulême. His opponents turned to Philip II of France for support, and the fighting spread through the Limousin and Périgord. The excessive cruelty of Richard's punitive campaigns aroused even more hostility. After Richard had subdued his rebellious barons he again challenged his father. From 1180 to 1183 the tension between Henry and Richard grew, as King Henry commanded Richard to pay homage to Henry the Young King, but Richard refused. Finally, in 1183 Henry the Young King and Geoffrey, Duke of Brittany, invaded Aquitaine in an attempt to subdue Richard. Richard's barons joined in the fray and turned against their duke. However, Richard and his army succeeded in holding back the invading armies, and they executed any prisoners. The conflict paused briefly in June 1183 when the Young King died. With the death of Henry the Young King, Richard became the eldest surviving son and therefore heir to the English crown. King Henry demanded that Richard give up Aquitaine (which he planned to give to his youngest son John as his inheritance). Richard refused, and conflict continued between them. This refusal is what finally made Henry II bring Queen Eleanor out of prison. He sent her to Aquitaine and demanded that Richard give up his lands to his mother, who would once again rule over those lands. To strengthen his position, in 1187, Richard allied himself with 22-year-old Philip II, the son of Eleanor's ex-husband Louis VII by Adela of Champagne. Roger of Howden wrote: The King of England was struck with great astonishment, and wondered what [this alliance] could mean, and, taking precautions for the future, frequently sent messengers into France for the purpose of recalling his son Richard; who, pretending that he was peaceably inclined and ready to come to his father, made his way to Chinon, and, in spite of the person who had the custody thereof, carried off the greater part of his father's treasures, and fortified his castles in Poitou with the same, refusing to go to his father. Overall, Howden is chiefly concerned with the politics
