The rules of procedure on such occasions are fully set out in the city’s "Liber Albus,"(312) and they contain, curiously enough, a provision expressly made for cases where the full notice of forty days had not been given. In such an event the prescribed rule was to send some of their more discreet citizens to the king and his council to ask for the appointment of another day. Whether Rokesley had taken this step before resorting to the measures he did we are not told. It was also the custom on such occasions for the citizens to gather at Barking Church, clothed in their best apparel, and thence proceed in a body to the Tower. A deputation was appointed—selected members of the common council—who should also proceed to the Tower for the purpose of giving an official welcome to the justiciars on behalf of the citizens. It was not thought to be in any way derogatory to secure the goodwill of the king’s justiciars by making ample presents. It had been done time out of mind. The sheriffs and aldermen were to attend with their respective sergeants and beadles, the benches at the Tower were to be examined beforehand and necessary repairs carried out, all shops were to be closed and no business transacted during the session. In a word, everything was to be done that could add to the dignity of the justiciars and the solemnity of the occasion. In contrast with all this, Rokesley’s conduct was indeed strange, and leads us to suppose that his action was caused by some other and stronger reason than the mere omission to give the usual notice of the coming of the king’s justiciars. (M198) Be this as it may, the king’s treasurer, who may possibly have been forewarned of what was about to take place, at once decided what course to take. He declared the city to be there and then taken into the king’s hands, on the pretext that it was found to be without a mayor, and he summoned the citizens to appear on the morrow before the king at Westminster. When the morrow came, the citizens duly appeared, and about eighty of them were detained. Those who accompanied Rokesley to Barking Church on the previous day were confined in the Tower, but after a few days they were all set at liberty, with the exception of Stephen Aswy, who was removed in custody to Windsor.(313) (M199) The king appointed Ralph de Sandwich _custos_ or warden of the city, enjoining him at the same time to observe the liberties and customs of the citizens, and for the next thirteen years (1285-1298) the city continued to be governed by a warden in the person of Sandwich or of John le Breton, whilst the sheriffs were sometimes appointed by the Exchequer and sometimes chosen by the citizens.(314) (M200)
