challenge to Lord Sidmouth, for which he was arrested, and sentenced to a year's imprisonment. He issued from gaol still more embittered against Sidmouth and his colleagues, and resolved on striking some mortal blow at them. He did not lack comrades of a like fiery and abandoned stamp, and they determined on a scheme for cutting off the whole Cabinet together. The detestable deed was to be perpetrated in the autumn of 1819, a time when the public mind, especially that of the working classes, was so embittered against the Government. They did not, however, succeed in their intentions, and it was at this crisis of unwilling delay that the man Edwards became privy to their plans. In November he carried the important, and, as he hoped, to him profitable secret to Sir Herbert Taylor, who was attached to the establishment of the king at Windsor, and by him he was introduced to Lord Sidmouth. This minister and his colleagues, with that fondness for the employment of spies, and for fomenting sedition instead of nipping it in the bud, immediately engaged Edwards, on good pay, to lead forward the conspirators into overt action. It was not enough for them that, by adding another witness or two to Edwards, they would be able to produce the most complete proof of the treason of these men--they rather luxuriated in the nursing of this plot, and thus ripening it into something bloody and horrible; and in this they succeeded. The Christmas holidays necessarily postponed the plans of the conspirators by the Ministers going out of town, and the deaths of the king and of the Duke of Kent produced further impediments by preventing the regular Cabinet meetings. At one moment the plan appeared to be in jeopardy from the Ministers being in danger of dismissal for their refusal to procure the new king a divorce; but all these hindrances only the more enabled Edwards to ply his arts, and stimulate his victims to their destruction. So thoroughly had he brought them to this point, that, on the 19th of February, they came to the resolution to assassinate the Ministers each at his own house, as they could not get them all together; but at this moment Edwards brought them word that the Ministers were going to have a Cabinet dinner the next day. To make sure, they sent out for a newspaper, and finding that it was so, Thistlewood remarked that as there had not been a Cabinet dinner for a long time, there would be fourteen or sixteen there, and it would be a fine haul to murder them all together. The dinner was to be at the house of Lord Harrowby, and it was planned that one of the conspirators should call with a note, and then the rest should rush in and put the Ministers all to death, and bring away the heads of Sidmouth and Castlereagh in bags provided for that purpose. They were then to fire the cavalry barracks by throwing fire-balls into the straw-sheds, and the people rising, as they hoped, on the spread of the news, they were to take the Bank and the Tower.
