The Lords had another pressing reason for giving way, for until the citizens were assured that the full penalty of the law would be executed on Strafford they determined to stop payment of the loan. Writing to Matthew Bradley on the 3rd May, the treasurer of the army tells him "a strange story." "There is," he says, "money ready in the city, but none will be delivered until justice be done upon my lord of Strafford."(445) On that very day, the letter continues, there had been a crowd of 10,000 well-to-do persons at Westminster—"citizens of very good account, some worth £30,000, some £40,000" demanding justice against Strafford and threatening to send their servants the next day unless justice were speedily executed. "Truly these unsettled times do much trouble me." (M183) The discovery of the so-called "army plot" had in the meanwhile led to a preamble being drawn up to a document known as the "Protestation," or declaration in favour of the reformed religion, in which the danger from the army was for the first time clearly mentioned. The Protestation passed the Commons on the 3rd May,(446) and on the following day received the assent of the House of Lords. On the 11th May a printed copy of this document was introduced into the Court of Aldermen, when it received the willing assent not only of the aldermen present, but also of the Town Clerk and the City Remembrancer.(447) On the 29th it was accepted by the Common Council, and two days later the mayor issued his precept for a house-to-house visitation to be made in every ward for the purpose of getting all the inhabitants of the city to give in their adherence to it.(448) (M184) Although the execution of Strafford somewhat allayed the nation’s fears of having "two armies brought into the bowels of the kingdom," they were soon revived by a second army plot. The armies thus became a constant source of danger as well as expense, and it was determined to disband them. Charles could not withhold his assent, and a poll tax was established for the purpose of raising the necessary funds. This was in July (1641).(449) The masters and wardens of the livery companies were forthwith called upon to make a return in writing of the names of every person who had been and then was master and warden of each company; the names of all the livery, yeomanry and freemen of each company, noting in the margin of the return those who had ever been fined for alderman or sheriff, and the parish and ward in which each individual member of the company resided. Every alderman was likewise instructed to make a return of the names of his deputy and common councilmen of his ward; the names of every merchant-stranger that kept house there, every English merchant and factor, and every popish recusant; and finally the names of everyone in the ward above the age of sixteen years not otherwise rated.(450) (M185)
