No record has survived of Fielding's share in the political struggles of his party, during his first two years of "intense application" to the law. Walpole's power had been sensibly lessened by the death of the Queen, and he was losing the support of the country and even of the trading classes. The Prince of Wales, now openly hostile to the "great man," was the titular head of an Opposition numbering almost all the men of wit and genius in the kingdom. Lyttelton, Fielding's warmest friend, had become secretary to the Prince, and was recognised as a fluent leader of the Opposition in the House of Commons. Another friend, John Duke of Argyll, had joined the ranks of the Opposition in the Lords. On the whole the author of _Pasquin_, may well have hoped for a speedy fall of the "Colossos," with "its Brains of Lead, its Face of Brass, its Hands of Iron, its Heart of Adamant," and the accession to power of a party not without obligations to the fearless manager of the little theatre in the Haymarket. During these years the Opposition, even though supported by Pope and Chesterfield, Thomson and Bolingbroke, could scarcely fail to utilise the trenchant scorn, the whole-hearted vigour, the boisterous humour, of Fielding's genius; and Murphy, speaking vaguely of Fielding's legal years, says that a "large number of fugitive political tracts, which had their value when the incidents were actually passing on the great scene of business, came from his pen." It is not however till November 1739, two years and a half after the pillorying of Walpole on the Haymarket boards, that Fielding is again clearly seen, 'laying about' him, in those clamourous eighteenth-century politics.
His choice of a new weapon of attack is foreshadowed in the noble concluding words of the _Introduction_ to the _Historical Register_; words written on the very eve of the Ministerial Bill gagging that and all other political plays: "If nature hath given me any talents at ridiculing vice and imposture, I shall not be indolent, nor afraid of exerting them, while the liberty of the press and stage subsists, that is to say while we have any liberty left among us." A few weeks after these words were published the liberty of the stage was triumphantly stifled by Walpole's Licensing Bill. But even "old Bob" himself dared not lay his hand on the liberty of the British Press; and so we find Mr Pasquin reappearing under the guise, or in the company, of the _Champion and Censor of Great Britain_, otherwise one _Captain Hercules Vinegar_, a truculent avenger of wrong and exponent of virtue, in whose fictitious name a political, literary, and didactic newspaper entered the field of party politics on November 15, 1739. The paper, under the title of the _Champion_, was issued three times a week, and consisted of one leading article, an anti-Ministerial summary of news, and literary notices of new books. The first number announced that the author and owner was the said Captain Hercules Vinegar, and that the Captain would be aided in various departments by members of his family. Thus the Captain's wife, Mrs Joan Vinegar, a matron of a very loquacious temper, was to undertake the ladies' column, and his son Jack was to have "an Eye over the gay Part of the Town." The criticism was to be conducted by Mr Nol Vinegar who was reported to have spent one whole year in examining the use of a single word in Horace. And the politics were to be dealt forth by the Captain's father, a gentleman intimately versed in kingdoms, potentates and Ministers, and of so close a disposition that he "seldom opens his Mouth, unless it be to take in his Food, or puff out the Smoke of his Tobacco."
