After the defeat and death of Simon de Montfort at Evesham, there was great alarm in the City. Some proposed to close the gates and call together the adherents of the Barons’ cause; others proposed immediate submission. The latter course prevailed. Letters of submission were drawn up and sent to the King at Windsor. The messengers on the way met Sir Roger de Lilbourne, who told them that he was sent to declare the King’s pleasure to the citizens. The King’s pleasure was immediate and complete submission: the removal of all chains and posts in the streets as a mark of submission, and the despatch of the Mayor and principal men of the City to Windsor under letters of safe conduct. They went. FitzThomas, unluckily, was once more Mayor. The King disregarded the letters of safe conduct and clapped them into prison. All of them, except FitzThomas, were shortly afterwards released. Henry remembered the words by which FitzThomas had sworn a limited loyalty. FitzThomas never again appeared. He vanished. Perhaps the King ordered his execution; perhaps he caused him to languish for the rest of his life in prison. However that may be, FitzThomas was no more seen. Henry came to London, his chief enemy in custody; he gave away sixty houses belonging to the principal citizens; he fined the City 20,000 marks. On the 6th of December of the same year (1265) John de la Linde, knight, and John Wallraven, clerk, were made seneschals, the Tower of London being delivered into their hands. On the same day there came to Westminster four-and-twenty citizens, who swore faithfully and safely to keep the City in the King’s behalf under their two seneschals. The King gave, further, London Bridge, with its tolls, to Queen Eleanor, who allowed it to fall into decay. She then gave it back to the City. FitzThedmar here remarks that some of the persons who had sided with the Earl of Gloucester took to flight, and there were among them some who, in the time of the late Mayor, FitzThomas, styled themselves the “Commons of the City.” On the election of a citizen “to attend to the duties of Sheriff of Middlesex and Warden of London,” the people clamoured for FitzThomas, who was probably by this time lying in his grave. The citizens petitioned, but in vain, for the right of electing their Mayor and Sheriffs. In the following year, 1266, John Adrian and Luke de Battencurt were chosen Bailiffs instead of Sheriffs.
