In 1816 he attended the notorious meeting in Spa-fields, where he acted as chairman; but it is only justice to say, that he had held no previous communication with Thistlewood and his colleagues, except for the purpose of striking out some portion of their resolutions, which he considered as offensive. In the year 1818, he appears to have become so flattered by the success which his previous exertions as a popular speaker had gained for him, that he resolved to stand for Westminster, in opposition to Sir Francis Burdett; but whatever may have been his popularity among his own peculiar party, the experiment was unsuccessful, and at the close of the poll it was found that his friends had given only forty-one votes for him; and he had also to regret his rashness in thus publicly thrusting himself forward, as, while upon the hustings, he was soundly horsewhipped by a gentleman, upon whom he had previously inflicted a cowardly and an unmerited injury.

In the year 1819 the principles of radicalism appear to have reached a point of almost ungovernable fury, and Hunt secured to himself the character of the best and firmest champion of the party, by his conduct at a public meeting, which took place at Smithfield at this period, and at which, in truth, it appears that he acted in a manner without reproach.

An event, however, soon afterwards occurred which procured for him still greater notoriety. The Manchester reformers, who had posted up notices of a meeting to be holden on the 9th of August in this year, for the purpose of proceeding to the election of a representative, as at Birmingham, where the people had, some time before, elected Sir Charles Wolseley as their legislatorial attorney or representative, was informed by the magistrates that as the object of the proposed assemblage was unquestionably illegal, it would not be permitted to take place. In consequence of this expressed determination on the part of the authorities, the meeting was abandoned, but fresh notices were issued for a new assemblage on the 16th of the same month, with the avowed legal object of petitioning for a reform in parliament. An open space in the town, called St. Peter’s Field, was selected as the place of meeting, and never upon any former occasion of a similar nature was so great a number of persons known to have met together. For some hours before the proceedings were appointed to commence, large bodies of people continued marching into Manchester from the neighbouring villages and towns, formed in ranks five deep, and many of them armed with stout staves, while the whole body stepped together as if trained for military purposes. Each party bore its own banners, and among others two clubs of female reformers made their appearance, bearing flags of white silk. By mid-day it was calculated that 60,000 persons had assembled. The magistrates, it appears, were anxious that the peace should be preserved, and a number of special constables were sworn in, who formed themselves in a line, from the house in which the justices were sitting, to the stage or waggon fixed as a platform for the speakers. Soon after the business of the meeting had commenced, a body of yeomanry cavalry entered the ground, and advanced with drawn swords towards the stage, when their commanding-officer called to Mr. Hunt, who was addressing the meeting, and informed him that he was his prisoner. Mr. Hunt endeavoured to procure tranquillity among the people, and offered to surrender himself to any civil officer who should present himself, and should exhibit his warrant; and a constable immediately advanced and took him into custody, with some other persons who were similarly engaged. Some uneasiness being now exhibited among the mob, the yeomanry cried out to seize their flags. The men stationed near the waggon, in consequence began to strike down the banners, which were attached to the platform, and a similar course being pursued with respect to those which were raised in other parts of the field, a scene of the most indescribable confusion ensued. The immense number of persons on the field, rendered it almost impossible for the military to move without trampling down some of them under foot; and some resistance being offered, many persons, including females, were cut down with sabres, and while some were killed, the number of wounded amounted to between three and four hundred. In a short time, however, the ground was cleared of its original occupants, and as they fled in all directions, military patroles were immediately placed in the streets, to preserve tranquillity.

It would be almost impossible to give any lengthened or minute description of this riot, or “massacre,” as it has always been called by the radical opponents of government, without in some degree entering into the very strong feeling of party prejudice, which has been universally excited upon the subject. The real circumstances of the case may be said to be unsettled even to this day; and while the magistrates and their friends declare that, the Riot Act having been read, the subsequent proceedings on the part of the soldiery were both justified and necessary, the friends of the people as invariably deny the allegation of the reading of the Riot Act, and therefore contend, that the introduction of a military force was harsh and unconstitutional. The whole transaction does not appear to have occupied more than ten minutes, in the course of which time the field seems to have been cleared of its recent occupiers, and filled with different corps of infantry and cavalry. Hunt and his colleagues were, after a short examination before the magistrates, conducted to solitary cells, on a charge of high-treason, and on the following day notices were issued by the magistrates, by which the practice of military training, alleged to have been carried on in secret, by large bodies of men, for treasonable purposes, was declared to be illegal. Public thanks were, by the same authority, returned to the officers and men of the respective corps engaged in the attack; and, on the arrival in London of a despatch from the local authorities, a cabinet council was held, the result of which was, the return of official letters of thanks to the magistrates, for their prompt, decisive, and efficient measures for the preservation of the public tranquillity; and to all the military engaged, for the support and assistance afforded by them to the civil power.

The circumstances of the Manchester case eventually turned out to be such, that government, by the advice of the law officers of the crown, found it expedient to abandon the threatened prosecution of Mr. Hunt and his colleagues for high-treason. Those persons were accordingly informed that they would be proceeded against for a conspiracy only, which might be bailed; but Mr. Hunt refused to give bail, even, as he said, to the amount of a single farthing: but some of his friends liberated him. On his return from Lancaster, where he had been confined, to Manchester, Hunt was drawn about two miles by women, and ten miles by men. In fact, his return was one long triumphal procession, waited upon by thousands, on horse, on foot, and in carriages, who hailed him with continued shouts of applause.

The sensation produced throughout the country by this fatal business was intense. Hunt’s conduct was universally applauded, and he received the thanks of nearly every county in England, and those even who opposed him on principle now forgot their enmity, and hailed him as the uncompromising champion of liberty. His entry into London was public, and some of the first characters of the day honoured him with their presence, whilst hundreds of thousands welcomed him with deafening applause.

The agitation had hardly subsided when true bills were found against Hunt and his companions, and their trials came on at York, and continued, without intermission, for fourteen days, during which time Hunt displayed powers of intellect, and acuteness of perception, of which even his friends did not suppose him to be possessed. He was found guilty, however, and ordered to be brought up to the Court of King’s Bench for sentence, but he afterwards moved, in person, for a new trial. Although he argued with all the tact and ability of the most experienced lawyer, his motion was refused, and he was sentenced to two years and a half imprisonment in Ilchester jail.

He had not been long incarcerated when he brought to light a system of the most infamous cruelty which had been practised on the unfortunate inmates of that prison by the barbarous jailor. Mr. Hunt himself, being treated with great cruelty, addressed a letter to Mr. Justice Bayley, detailing cases of atrocious cruelty; and the question being at length brought before the House of Commons, an inquiry followed. Hunt substantiated all his charges, and the inhuman jailor was dismissed and punished, while the country rang with the praises of his accuser.

The period of his imprisonment having expired, he again made a public entry into London; but he found that the times had changed, even during that short time. The public prosperity had banished discontent, and with it that wild enthusiasm, which had before been exhibited in his favour, and he was greeted with none of those demonstrations of delight which had been before exhibited. He made several attempts to arouse the lethargy of his former admirers, but in vain; and he at length betook himself to repair his broken fortunes by the manufacture of English coffee, with roasted corn, and subsequently in 1824 he added that of blacking; and so successful was he in this enterprise, that “Hunt’s matchless” became almost as celebrated as the polish of Messrs. Day and Martin.

Mr. Hunt was subsequently returned as member for Preston in Lancashire, and he died while yet representing that place in parliament.
