[Sidenote: The coronation of George IV, 19 July, 1821.] The coronation was originally fixed for Tuesday, the 1st August, but was subsequently postponed to Thursday, the 19th July, 1821.[756] The City lost no time in sending in its customary claim of services; and the masters and prime wardens of the twelve principal livery companies were invited, as usual, to assist the lord mayor in his duties at the coronation banquet.[757] These services were now performed for the last time, the coronation banquet and all ceremonial in connexion therewith in Westminster Hall being dispensed with, by royal proclamation, at the accession of William IV.[758] [Sidenote: City addresses to Queen Caroline, June, 1820.] The ceremony was somewhat marred by an injudicious attempt of the unhappy queen to force her way into the abbey. Whatever may have been the extent of her folly or her guilt no one can question the misfortune of Queen Caroline. From the first moment of their meeting she was treated by her husband with scant courtesy and was soon forced to quit his side and lead a life of retirement at Blackheath. A watch was set on her movements and her conduct made the subject of a private enquiry by the lords. The City was no less indignant than the princess herself at such a proceeding. The livery presented her with an address of sympathy,[759] and at the close of the enquiry the Common Council congratulated her upon having escaped from a "foul and atrocious conspiracy against her life and honour."[760] The Court of Aldermen, however, once more held aloof. This was in 1813. In the following year she withdrew disgusted to the continent and there remained until her husband succeeded to the throne. Again the livery and the Common Council presented addresses and testified their attachment to one whom most people looked upon as an injured woman, who had in vain challenged her accusers to appear before a public and impartial tribunal.[761] Her wish was now to be gratified. [Sidenote: The queen's trial, Aug.-Nov., 1820.] Another secret enquiry into her conduct was held by the lords, at the king's command, and upon evidence thus scraped together and unsupported by oath a Bill of Pains and Penalties was introduced into the House of Lords for depriving the queen of her title and dissolving her marriage. The Common Council entered a strong protest and appealed to both Houses to reject the Bill,[762] but in vain. The queen was put on her defence, and after a protracted trial succeeded with the help of her learned counsel--Brougham, Denman and Lushington--in placing her conduct in such a light that the Bill had to be abandoned.
