‘The duke of Orleans and Henry of Lancaster agreed mutually to labour and assist each other to accomplish the deaths of the two kings, that they might obtain the crowns of France and England,—that of France for Louis d’Orleans, and that of England for Henry of Lancaster.

‘Henry succeeded in his attempt, but, thank God! the duke of Orleans has failed.
