"This is a daguerreotype (an early form of photograph) of the Chartist meeting held at Kennington Common on 10th April 1848. It was the last time the Chartists attempted to present a petition to Parliament. Fearing an attempted revolution, the Government prepared immensely for the meeting and filled London with 85,000 special constables, as well as putting 8,000 soldiers on alert.
