Luis de Valois
Duke John IV wanted to ingratiate the favor of France, and thus besieged Josselin. By 1394 King Charles VI however restored confidence in Olivier and although Philip of Artois succeeded him in 1392, the King confirmed his function as the Constable. In 1397 [[Louis de Sancerre]] was also appointed Constable, replacing the deceased [[Philippe of Artois]], but Olivier retained the privilege of being the holder of the Constable sword. By 1397 Olivier had also formed a secondary Royal alliance with [[Louis I, Duke of Orléans|Louis d'Orleans]], brother of King Charles VI.
