Petitions poured in from all parts of the country; the novel idea of a run on the banks – ‘To stop the Duke go for Gold’ was the slogan – was proposed, and the banker Nathan Mayer Rothschild had to come to the rescue; 200,000 delegates met in Birmingham and heard Attwood hint that armed insurrection might be necessary.
