This Day in History: 1455-03-15

In mid-March 1455, Richard Neville, Earl of Salisbury, ordered his son, the Earl of Warwick, to release the scheming Henry Holland, Duke of Exeter, from his place of imprisonment at Pontefract Castle. Henry had been imprisoned for involving himself in the Northern war between the Neville and the Percy families, which was in direct disobedience to an oath all lords had taken to keep and respect royal authority during the illness of Henry VI.
