Before the Duke came we had all been talking of the Lord Mayor's Day, and the manner in which we should go into the City and return, and the precautions taken against riot.
The Duke and Peel came together, and it was evident from the first words the Duke spoke that he and Peel had made up their minds to put off the King's visit to the City. The Chancellor seemed almost to take fire at the idea of this, but the Duke very quietly begged him to hear the letters before he decided. The Duke then read various letters he had received, all warning him against going, as there was a plot to assassinate him, and raise a tumult. One of them was from Pearson, a Radical attorney. There was one from a coachmaker, saying he was satisfied, from what his men told him, there was such a design, and offering to come with eighteen of his people and guard the Duke. There was another offer, in a letter not read, to the same effect. There was an examination of a man who serves a Radical printer, and who formerly lived with Cobbett, which showed the intention to exist of attacking the Duke. The impression seemed to be general that the attempt would be made. There was a letter from the Lord Mayor elect (Alderman Key) to the Duke, telling him there was an intention amongst disaffected persons to excite tumult and confusion, and to attack him; that he could not be in safety without a guard, and a strong one; and that if an attack was made in one quarter the civil force would not be sufficient.
The Duke said he would not go. Peel, who had received many letters informing him of the intention to assassinate him, said if he went he would go privately, and come away privately. He observed that if our force, the disposition of which was mentioned, and was admirable, succeeded in putting down a riot along the line of the procession, he could not answer for the security of life or property in other parts of the town. We had information that the Duke's house would be attacked while he was in the City, and it was to be feared that fires might take place to exercise terror and create a diversion.
The feeling in the Duke's mind was that we should not be justified in giving an occasion for the shedding of blood, by means of a crowd of our own making. The consequences of the collision would be incalculable, and might affect all parts of England.
The consequences of putting off the King's visit were not lost sight of; the effect it would produce on the Funds, and on public confidence—all that would be said against the Government as weighing down the King by its unpopularity.
The letter it was proposed to send was written, and the Duke and Peel went with it to the King at a little before seven.
While they were gone the feeling of the Cabinet underwent a change. Lord Bathurst first observed that it would put an end to the Government, and carry Reform. The Chancellor was most unwilling to postpone the King's visit. It would be said we did it for our sakes only, and sacrificed him. Lord Bathurst thought the King would take the advice, but be very angry, and get rid of us.
There would be a violent storm in Parliament, and the mobs would come to our houses. All these feelings rested upon the supposition that the procession could return without a tumult, but the letter had been written on the supposition that it could not; which was the correct one. The Duke and Peel came back and told us the King had thought the advice quite right, and had behaved as well as possible. The tears were in his eyes while the Lord Mayor's letter was read. He said he had already determined in his own mind to bring the Duke and Peel back in his own carriage. The Duke thought the King had rather expected the advice, and that his mind was relieved by it.
We knew the Queen was much alarmed; but it had been said that the King would not hear of there being any danger.
The account of the King's manner of receiving the advice seemed to tranquillise those who had before been dissatisfied with the resolution which had been come to. We then went to the Home Office, where we found Alderman Thompson, Mr. Oldham (the Chairman of the Entertainment Committee), Lord Hill, Lord F. Somerset, Sir W. Gordon, General Macdonald, and Mr. Phillips. There were two City men I did not know.
