Robert's Rebellion and his decision to leave his inheritance

Robert, a knight in his mid-20s, defied his father, King William, and abandoned his inheritance. He had three options - return to his father's court with worsened honor, live as a knight errant and decrease his lifestyle, or launch a rebellion against his own father. He chose the rebellion, backed by wealthy and politically well-positioned friends. With surprise on his side, he rode hard for Ruwan, hoping to take it and show William the need to let go of Normandy. However, they were met with resistance and were unable to take the tower.
