[Sidenote: The duke of Burgognie prepareth to besiege Calis.] Iohn duke of Burgognie hauing obteined licence to besiege Calis, prepared an armie of six thousand men of armes, fiftéene hundred crosbowes, & twelue thousand footmen, the which being assembled, and all necessarie prouision readie at saint Omers, he was by the French king countermanded, and not suffered to proceed anie further in that weightie enterprise. [Sidenote: The chéefe root of the malice betwixt the dukes of Burgognie & Orleance.] And this was thought to be partlie the cause of the malice that he conceiued against the duke of Orleance, supposing that through him (enuieng his glorie) he was thus disappointed of his purpose. Whilest such dooings were in hand betwixt the English and French, as the besieging of Marke castell by the earle of saint Paule, and the sending foorth of the English fléet, vnder the gouernance of the lord Thomas of Lancaster, and the earle of Kent, the king was minded to haue gone into Wales against the Welsh rebels, that vnder their chéefteine Owen Glendouer, ceassed not to doo much mischéefe still against the English subiects. But at the same time, to his further disquieting, [Sidenote: A new cōspiracie against king Henrie by the earle of Northumberland & others.] there was a conspiracie put in practise against him at home by the earle of Northumberland, who had conspired with Richard Scroope archbishop of Yorke. Thomas Mowbraie earle marshall sonne to Thomas duke of Norfolke, who for the quarrell betwixt him and king Henrie had béene banished (as ye haue heard) the lords Hastings, Fauconbridge, Berdolfe, and diuerse others. It was appointed that they should meet altogither with their whole power, vpon Yorkeswold, at a daie assigned, and that the earle of Northumberland should be cheefteine, promising to bring with him a great number of Scots. The archbishop accompanied with the earle marshall, deuised certeine articles of such matters, as it was supposed that not onelie the commonaltie of the Realme, but also the nobilitie found themselues gréeued with: which articles they shewed first vnto such of their adherents as were néere about them, & after sent them abroad to their fréends further off, assuring them that for redresse of such oppressions, they would shed the last drop of blood in their bodies, if néed were.
