Tudor Books, Holinshed's Chronicle 1415

[31st July 1415] When king Henrie had fullie furnished his navie with men, munition, & other provisions, perceiving that his capteines misliked nothing so much as delaie, determined his souldiors to go a ship-boord and awaie. But see the hap, the night before the daie appointed for their departure, he was crediblie informed, that Richard earle of Cambridge brother to Edward duke of Yorke, and Henrie lord Scroope of Masham lord treasuror, with Thomas Graie a knight of Northumberland, being confederat togither, had conspired his death: wherefore he caused them to be apprehended. The said lord Scroope was in such favour with the king, that he admitted him sometime to be his bedfellow, in whose fidelitie the king reposed such trust, that when anie privat or publike councell was in hand, this lord had much in the determination of it. For he represented so great gravitie in his countenance, such modestie in behaviour, and so vertuous zeale to all godlinesse in his talke, that whatsoeuer he said was thought for the most part necessarie to be doone and followed. Also the said sir Thomas Graie (as some write) was of the kings privie councell.

These prisoners upon their examination, confessed, that for a great summe of monie which they had received of the French king, they intended verelie either to have delivered the king alive into the hands of his enimies, or else to haue murthered him before he should arrive in the duchie of Normandie. When king Henrie had heard all things opened, which he desired to know, he caused all his nobilitie to come before his presence, before whome he caused to be brought the offendors also, and to them said. 'Hauing thus conspired the death and destruction of me, which am the head of the realme and gouernour of the people, it maie be (no doubt) but that you likewise have sworne the confusion of all that are here with me, and also the desolation of your owne countrie. To what horror (O lord) for any true English hart to consider, that such an execrable iniquitie should ever so bewray you, as for pleasing of a forren enimie to imbrue your hands in your bloud, and to ruine your owne native soile. Revenge herein touching my person, though I séeke not; yet for the safegard of you, my déere fréends, & for due perseruation of all sorts, I am by office to cause example to be shewed. Get ye hence therefore ye poore miserable wretches to the receiving of your just reward, wherein Gods majestie give You grace of his mercie and repentance of your heinous offenses.' And so immediatlie they were had to execution.
