The barons had already taken their resolution. The moment the decision was announced to them they declared that it was, on the face of it, contrary to truth and justice, and had been procured by the undue influence which the Queen of Louis, the sister-in-law to Henry, possessed over the mind of her husband. Hostilities immediately recommenced; and as every man of property was compelled to adhere to one of the two parties, the flames of civil war were lighted up in almost every part of the kingdom. In the North, and in Cornwall and Devon, the decided superiority of the royalists forced the friends of the barons to dissemble their real sentiments; the midland counties and the marches of Wales were pretty equally divided: but in the Cinque Ports, the metropolis, and the neighboring districts Montfort ruled without opposition. His partisan, Thomas Fitz-Thomas, had been intruded into the office of mayor of London; and a convention for their mutual security had been signed by that officer and the commonalty of the city on the one part, and the earls of Leicester, Gloucester, and Derby, Hugh le Despenser, the grand justiciary, and twelve barons on the other. In the different wardmotes every male inhabitant above twelve years of age was sworn a member of the association: a constable and marshal of the city were appointed; and orders were given that at the sound of the great bell at St. Paul's all should assemble in arms and obey the authority of these officers. The efficacy of the new arrangements was immediately put to the test. Despenser, the justiciary, came from the Tower, put himself at the head of the associated bands, and conducted them to destroy the two palaces of the King of the Romans, at Isleworth and Westminster, and the houses of the nobility and citizens known or suspected to be attached to the royal cause. The justices of the king's bench and the barons of the exchequer were thrown into prison; the moneys belonging to foreign merchants and bankers, which for security had been deposited in the churches, were carried to the Tower; and the Jews, to the number of five hundred, men, women, and children, were conducted to a place of confinement. Out of these, Despenser selected a few of the more wealthy, that he might enrich himself by their ransom; the rest he abandoned to the cruelty and rapacity of the populace, who, after stripping them of their clothes, massacred them all in cold blood. Cock ben Abraham, who was considered the most opulent individual in the kingdom, had been killed in his own house by John Fitz-John, one of the barons. The murderer at first appropriated to himself the treasure of his victim; but he afterward thought it more prudent to secure a moiety, by making a present of the remainder to Leicester.[61]
