Thomas was held prisoner for in his family castle for one year as an attempt to prevent him from joining the Dominicans.
Thomas's mother realized that she couldn't change Thomas's mind about the Dominican and sought to save the family's dignity. She arranged for him to escape at night through his window. She thought that a secret escape from detention was better than an open surrender.
