Anglo-Saxon Chronicle. 1065. Soon after this all the thanes in Yorkshire and in Northumberland gathered themselves together at York, and outlawed their Earl Tosty (age 39); slaying all the men of his clan that they could reach, both Danish and English; and took all his weapons in York, with gold and silver, and all his money that they could anywhere there find. They then sent after Morkar, son of Earl Elgar, and chose him for their earl. He went south with all the shire, and with Nottinghamshire and Derbyshire and Lincolnshire, till he came to Northampton [Map]; where his brother Edwin came to meet him with the men that were in his earldom. Many Britons also came with him. Harold (age 43) also there met them; on whom they imposed an errand to King Edward (age 62), sending also messengers with him, and requesting that they might have Morcar for their earl. This the king granted; and sent back Harold (age 43) to them, to Northampton, on the eve of St. Simon and St. Jude; and announced to them the same, and confirmed it by hand, and renewed there the laws of Knute. But the Northern men did much harm about Northampton, whilst he went on their errand: either that they slew men, and burned houses and corn; or took all the cattle that they could come at; which amounted to many thousands. Many hundred men also they took, and led northward with them; so that not only that shire, but others near it were the worse for many winters.

Froissart. WHEN the queen (age 31) and her barons and all her company were lodged at their ease, then they besieged the castle [Map] as near as they might. The queen (age 31) caused sir Hugh Spencer (deceased) the elder and the earl of Arundel (age 20) to be brought forth before Edward her son (age 13) and all the barons that were there present, and said how that she and her son (age 13) should take right and law on them according to their deserts. Then sir Hugh Spencer (deceased) said, 'Madam, God be to you a good judge and give you good judgment1, and if we cannot have it in this world, I pray God we may have it in another.' Then stept forth Sir Thomas Wake (age 29), a good knight and marshal of the host, and there openly he recounted their deeds in writing, and then turned him to another ancient knight to the intent that he should bring him on that case fauty1, and to declare what should be done with such persons, and what judgment they should have for such causes. Then the said knight counselled with other barons and knights, and so reported their opinions, the which was, how they had well deserved death for divers horrible deeds, the which they have commised, for all the trespass rehearsed before to justify to be of truth;3 wherefore they have deserved for the diversities of their trespasses to have judgment in three divers manners-first, to be drawn, and after to be headed, and then to be hanged on the gibbet. This in likewise as they were judged so it was done and executed before the castle of Bristow [Map] in the sight of the king and of sir Hugh Spencer the younger (deceased). This judgment was done in the year of our Lord MCCCXXVI., on Saint Denis' day in October [Note. Saint Denis' day is 09 Oct not 27 Oct?].
Note 1. This should be, 'God give us a good judge and good judgment ' ; but Verard's edition, from which the translation was made, has 'vous' for 'nous.'
Note 2. This appears to mean, ' To the intent that he should find him guilty on the charge' ('fauty' for 'faulty'); but the original means, 'To the intent that he should declare upon his fealty (féaulté) what should be done with such persons,' etc.
Note 3. Or rather as follows: ' That the accused had well deserved death for divers horrible deeds which they had heard in that place rehearsed, and held them for true and manifest.'
