 John the Fearless accused Isabeau and Orléans of fiscal mismanagement and again demanded money for himself , in recompense for the loss of royal revenues after his father 's death ; an estimated half of Philip the Bold 's revenues had come from the French treasury . John raised a force of 1 @,@ 000 knights , and entered Paris in 1405 . Orléans hastily retreated with Isabeau to the fortified castle of Melun , with her household and children a day or so behind . John immediately left in pursuit , intercepting the party of chaperones and royal children . He took possession of the Dauphin , and returned him to Paris under control of Burgundian forces ; however , the boy 's uncle , the duke of Berry , quickly took control of the child at the orders of the Royal Council . At that time Charles was lucid for about a month and able to help with the crisis . The incident , that came to be known as the <unk> of the dauphin , almost caused full @-@ scale war , but it was averted . Orléans quickly raised an army while John encouraged Parisians to revolt . They refused , claiming loyalty to the King and his son ; Berry was made captain general of Paris and the city 's gates were locked . In October Isabeau became active in mediating the dispute , in response to a letter from Christine de Pizan and an ordinance from the Royal Council .
