The chief leader of the movement was the crack-brained fanatic, Lord George Gordon, who led a mob some thousands strong, wearing blue cockades, through the city to Westminster with a petition which he desired to lay before the House of Commons. A motion that the petition should be brought up was seconded by Alderman Bull. This took place on Friday, the 2nd June. Whilst Lord George was thus engaged, the mob clamoured to be admitted into the House and would have forced an entrance, but for the arrival of a party of horse and foot guards. Foiled in their attempt to intimidate the House, the mob dispersed in various directions, and proceeded to sack and burn the Roman Catholic chapels attached to the Sardinian and Bavarian embassies, standing in Duke Street, Lincoln's Inn Fields, and Warwick Street, Golden Square, and having so far wreaked their vengeance they retired to rest for the night.[455] [Sidenote: Riot in Moorfields, 4 and 5 June, 1780.] Matters were not allowed to rest here. On Saturday afternoon (3 June), Kennet, the lord mayor, received a letter from Lord Stormont, secretary of state, forewarning him of the likelihood of tumults arising within his jurisdiction and strongly recommending him to take the necessary steps for preserving the peace. The day passed off quietly, however. A few people gathered in Ropemakers Alley, Little Moorfields, where stood a Roman Catholic chapel, but no disturbance took place. On Sunday afternoon (4 June) matters took a turn for the worse, and the mayor, being informed that a very great concourse of people had assembled in Moorfields in a riotous manner, and was threatening the chapel, at once sent for the marshals and their men and instructed them to procure as many constables as possible, and disperse the mob. In the evening the mayor himself went to the scene of riot, and stayed there until three o'clock in the morning. In the course of the night he received another and more urgent letter from Lord Stormont;--"I cannot but hope, and trust from your lordship's known zeal and activity that every effectual legal method will be used by you to preserve the public peace by guarding it against those dangers to which it stands exposed." The mayor was quick to grasp the situation. There were not nearly sufficient constables procurable to put down the riot, and those that were present declined to exert themselves to save the property of Roman Catholics. Kennet therefore took the only course open to him, and sent to the Tower for military assistance. The commander, however, was slow to give the aid required, and could be prevailed upon to send no more than 73 men, all told, and even these were sent in detachments. The force was utterly inadequate to cope with the crowd, but fortunately the mob were by this time ready to listen to the appeals of the mayor and aldermen, and quiet was at length restored. The mayor went home to seek a much needed rest, leaving one of the sheriffs on the spot in case of emergency.
