On 2 June 1780 a huge crowd, estimated at 40,000 to 60,000 strong, assembled and marched on to the Houses of Parliament. Many of them carried flags and banners proclaiming "No Popery", and most wore blue cockades which had become the symbol of their movement. As they marched, their numbers swelled. They attempted to force their way into the House of Commons, but without success. Lord Gordon, petition in hand, and wearing in his hat the blue cockade of the Protestant Association, entered the Commons and presented the petition. Outside, the situation quickly got out of hand and a riot erupted. Members of the House of Lords were attacked as they arrived, and a number of carriages were vandalized and destroyed. Despite being aware of the possibility of trouble, the authorities had failed to take steps to prevent violence breaking out. The Prime Minister, Lord North, had forgotten to issue an order mobilising the small number of Constables in the area. Those that were present in the House of Commons were not strong enough to take on the angry mob. Eventually a detachment of soldiers were summoned, and they dispersed the crowd without violence. Inside the House of Commons, the petition was overwhelmingly dismissed by a vote of 192 to 6. Lord Gordon was later sentenced to Newgate Gaol, but before that, this once pious Catholic converted to orthodox Judaism.
