The citizens had also in the meanwhile witnessed the arrest and execution of the Duke of Buckingham, son of the duke who figured so prominently before the citizens when the crown was offered to Richard III at Baynard Castle. He was seized one day whilst landing from his barge at the Hay Wharf, on a number of charges all more or less frivolous. His attendants were dismissed to the duke’s "Manor of the Rose," in the parish of St. Laurence Pountney(1099)—on the site of which recently stood Merchant Taylors’ School—whilst he himself was conducted to the Tower (16 April, 1521). An indictment was laid against him at the Guildhall before Sir John Brugge, lord mayor, and others (8 May). After a trial at Westminster which lasted some days, he was found guilty of high treason, and condemned to be hanged, drawn and quartered, and to suffer such other atrocities as usually accompanied the death of a traitor in those days. The king, however, satisfied with his condemnation, spared him these indignities, and the duke was allowed to meet his death at the block. His corpse was reverently carried from the Tower to the Church of the Austin Friars by six poor members of that Order.(1100) The duke had other friends in the city besides these poor religious men, who thus requited in the only way they could many acts of kindness done to their Order by Buckingham in his life time, and his death gave rise to much disaffection and seditious language for some time afterwards.(1101) (M580) Before the emperor left England he succeeded in committing Henry to an invasion of France. In order to carry out his object the king needed money, and the City was asked to furnish him with the sum of £100,000.(1102) Ten days later (26 May) the City agreed to advance £20,000. The livery companies were to be called upon to surrender their plate, and foreigners as well as citizens were to be made to contribute.(1103) (M581) The question arose whether the aldermen should be jointly assessed with the commoners or by themselves. The mayor and aldermen were willing to contribute the sum of £3,000,(1104) but this offer the Common Council "nothyng regarded," but sent the common sergeant to talk the matter over with them. After long consultation the mayor and aldermen sent back word that it was more "convenient" that they should be assessed with the commoners and not to be severed.(1105)
