Des Roches used his new authority to begin stripping his opponents of their estates, circumventing the courts and legal process. Complaints from powerful barons such as William Marshal's son Richard Marshal, 3rd Earl of Pembroke, grew, and they argued that Henry was failing to protect their legal rights as described in the 1225 charters. A fresh civil war broke out between des Roches and Richard's followers. Des Roches sent armies into Richard's lands in Ireland and South Wales. In response, Richard allied himself with Prince Llywelyn, and his own supporters rose up in rebellion in England. Henry was unable to gain a clear military advantage and became concerned that Louis of France might seize the opportunity to invade Brittany – where the truce was about to expire – while he was distracted at home.
