Froissart Book 4 Chapter 92. 1397. The resentments of the citizens began to cool, and they offered to mediate between the king (age 29) and the [her brother-in-law] duke of Lancaster (age 56), who was mightily angered by the murder of his [her husband] brother (age 41). He bethought himself, however, that as his nephew was married to the daughter (age 7) of the king of France (age 28), should he wage war against king Richard, his two daughters married in Castille and Portugal might suffer for it, from the French carrying a war into those countries. The duke was beside forced to change his mind, whether he would or not, from the solicitations of the citizens of London and some of the English prelates, who had been the mediators between the king and his uncles. The king obtained peace, on promising from that day forward to be solely guided by the advice of the duke of Lancaster, engaging never to do anything without first consulting him. The promise, however, he paid not any regard to, but followed the counsels of the rash and evil-minded, for which hereafter he severely suffered, as shall be related in this history. Thus did the king of England gain peace from his uncles for the murder of the duke of Gloucester, and now governed more fiercely than before. He went with his state to Pleshy [Map] in Essex, which had belonged to his uncle of Gloucester, and should have descended to his son [her son] Humphrey (age 16) as heir to his father; but the king took possession of it, for it is the rule in England for the king to have the wardship of all children who have lost their fathers, and are under twenty-one years of age at which period their estates are restored to them. King Richard took his cousin Humphrey of Gloucester in ward, appropriating all his possessions to his own profit. He made him live with him, and the duchess (age 31) and her two daughters with the queen.

Froissart Book 4 Chapter 92. 1397. The late [her husband] duke of Gloucester (age 41) was by inheritance constable of England; but the king (age 29) deprived his [her son] heir (age 16) of it, and gave it to his cousin the earl of Rutland (age 24). The king now assumed a greater state than ever king of England had done before, nor had there been any one who had expended such large sums by one hundred thousand nobles. He also took the wardship of the heir (age 15) of [her uncle] Arundel (age 51), son to the late earl whom he had beheaded in London, as has been related, and forced him to live with him. And because one of the knights of the late duke of Gloucester, named Cerbec, had spoken too freely of the king and council, he was arrested and instantly beheaded. Sir John Lacquingay was likewise in some peril; but, when he saw the turn affairs had taken, he quitted the service of the duchess of Gloucester (age 31), and fixed his abode elsewhere. At this period there was no one, however great, in England, that dared speak his sentiments of what the king did or intended doing. He had formed a council of his own from the knights of his chamber, who encouraged him to act as they advised. The king had in his pay full two thousand archers, who were on guard day and night, for he did not think himself perfectly safe from his uncles or the Arundel family.¹

Note 1. For more ample particulars respecting the murder of the duke of Gloucester, I must refer the reader to Mr. Gough's History of Pleshy.

Froissart Book 4 Chapter 94. Before 19 Oct 1398. You must know that the earl of Derby (age 31) and the late [her former husband] duke of Gloucester had married two sisters [Note. [her sister] Mary Bohun and Eleanor Bohun Duchess Gloucester (age 32)], daughters to the [her father] earl of Hereford and Northampton, constable of England: the children, therefore, of the earl of Derby and duke of Gloucester were cousins-german by their mother's side, and one degree removed by their father's. To say the truth, the death of the duke of Gloucester had displeased many of the great barons of England, who frequently murmured at it when together; but the king had now so greatly extended his power, none dared to speak of it openly, nor act upon the current rumours of the mode of his death. The king had caused it to be proclaimed, that whoever should say anything respecting the duke of Gloucester or the [her uncle] earl of Arundel, should be reckoned a false and wicked traitor and incur his indignation. This threat had caused many to be silent, afraid of what might befal them, who were, nevertheless, much dissatisfied.

Froissart Book 4 Chapter 92. You may suppose, that when news was carried to Pleshy [Map] of the duke of Gloucester's arrest, the duchess and her children were greatly dismayed, and, since such a bold measure had been taken, were much afraid of the consequences. Suspecting the duke's life was in great danger, they consulted sir John Laquingay what would be best for them now to do. The knight advised them to send instantly to the dukes of Lancaster and York, the duke's brothers; for by their mediation, perhaps, the king's choler would be appeased. He saw no other means, as the king would not choose to make them his enemies. The duchess of Gloucester followed this advice of the knight, and instantly despatched messengers to both, for they resided at a distance from each other. They were much enraged at hearing their brother was arrested, and returned answers to the duchess, not to be too much distressed at what had happened, for the king would not dare to treat him otherwise than by fair and legal measures, for it would not be suffered. This answer comforted the duchess and her children.
