While in Paris, he was challenged to fight by a Captain Forbes, on account of the reflections which he had cast upon the birthplace of the gallant captain, Scotland; but he declined the invitation, alleging that he had still an affair to settle with Lord Egremont before he could venture to take any other duel upon his hands. The death of that noble lord, however, left him free to fight; but on his writing to accept the challenge, his antagonist was not to be found. Mr. Wilkes subsequently returned to London, and gave notice that he should appear to answer the charges preferred against him on a certain day; and then having appeared in his place, as an alderman, in Guildhall, on his return, the mob took the horses from his carriage and dragged it to his house, crying "Wilkes and liberty!" On the 21st of February 1764, the trial of Mr. Wilkes, upon the accusations alleged against him, came on before Lord Mansfield, and he was found guilty on both charges, subject to arguments upon certain points as to the validity of his apprehension, the seizure of his papers, and the judgment of outlawry which had been obtained against him. The discussions preliminary to these arguments occupied the courts at various times during a space of two years; and in the mean time, the popularity of Mr. Wilkes and the outrages of the mob increased daily. At length, on the 27th of April 1768, Mr. Wilkes having been served with a writ of _Capias utlagatum_, was brought to the floor of the Court of King's Bench in the custody of the proper officer, in order that the question of his being admitted to bail might be considered. A long argument took place, but it terminated in favour of the crown, and Mr. Wilkes was conveyed to the King's Bench prison. On his way thither the mob seized the coach in which he was carried, and taking the horses from it, dragged him to a public-house in Spitalfields, where they permitted him to alight; but at about eleven o'clock at night he effected his escape from his over-zealous friends, and proceeding to the prison, immediately surrendered himself into lawful custody. On the following day he was visited by many of his friends; and a vast mob having collected outside the prison, it was feared that some outrage would be committed. All remained quiet, however, until night, when the rails by which the prison wall was surrounded were pulled up and burned as a bonfire, and the inhabitants of Southwark were compelled to illuminate their houses; but upon the arrival of a captain's guard of soldiers, the crowd dispersed without doing any further mischief.
