Also they sent into Flanders to the Lady Margaret, sister to King Edward and late wife to Charles, Duke of Burgoyne, to purchase, aid and help at her hands. This Lady Margaret bore no small rule in the low countries, and in very deed sore grudged in her heart that the King Henry (being descended of the house of Lancaster) should reign and govern of the realm of England, and therefore though she well understood that this was but a coloured matter, yet to work her malicious intention against King Henry, she was glad to have so fit an occasion, and therefore promised the messengers all the aid that she should be able to make in furtherance of the quarrel, and also to procure all the friends she could in other places to be aiders and partakers of the same conspiracy. King Henry, advertised of all these doings, was greatly vexed therewith, and therefore to have good advice in the matter he called together his council at the Charterhouse beside his manor of Richmond, and there consulted with them, by which means lest this begun conspiracy might be appeased and disappointed without more disturbance. It was therefore determined that a general pardon should be published to all offenders that were content to receive the same. This pardon was so freely granted that no offence was excepted, no not so much as high treason committed against the King's royal person. It was further agreed in the same council for the time then present that the Earl of Warwick should personally be shewed abroad in the city and other public places; whereby the untrue report falsely spread abroad that he should be in Ireland, might be among the community proved and known for a vain imagined lie. When all things in this counsel were sagely concluded and agreed to the King's mind, he returned to London, giving in commandment that the next Sunday ensuing, Edward, the young Earl of Warwick, should be brought from the Tower through the most public streets in all London, to the cathedral church of St. Paul. Where he went openly in procession, that every man might see him, having communication with many noble men and with them especially that were suspected to be partakers of the late begun conspiracy, that they might perceive how the Irishmen upon a vain shadow moved war against the King and his realm. But this medicine little availed evil disposed persons. For the Earl of Lincoln, son to John de la Poole, Duke of Suffolk, and Elizabeth, sister to King Edward the Fourth thought it not meet to neglect and omit so ready an occasion of new trouble.
