Having dismissed his Parliament, Cromwell had to take summary measures with the host of conspirators whom his refractory Parliaments had only tended to encourage. Since the "Killing no Murder" of Sexby, there were numbers who were by no means careful to conceal that they loved these doctrines, and persuaded the discontented that to kill Cromwell was to cure all the evils of the nation. The Royalists, on their part, who had always been advocates and practisers of assassination, were more than ever on the alert. In the beginning of the year 1658 the plan of an invasion was completed. The King of Spain furnished one hundred and fifty thousand crowns towards fitting it out: arms, ammunition, and transports were purchased in Holland, and the port of Ostend was to be the place of embarkation. The greatest drawback to the hopes of the Royalists were the dissipated and debauched habits of the king. Ormond, writing to Hyde, observed that he feared Charles's immoderate delight in empty, effeminate, and vulgar conversation was become an irresistible part of his nature, and would never suffer him to animate his own designs and the actions of others with that spirit which was necessary for his quality, and much more for his fortunes. Yet this was the man on whom their hopes of the restoration of monarchy were built. Ormond and O'Neil ventured to England in disguise, in order to ascertain what were really the resources and the spirit of the Royalists in the country. Ormond had private communication with all parties--with the Earls of Manchester and Denbigh, with Rossiter and Sir William Waller, as Presbyterians opposed to Cromwell and the Independents; with Saye and Sele and others, who were willing that Charles should return on his signing the same articles that his father had offered in the Isle of Wight; and with such of the fanatic Levellers as held the opinions of Sexby. But he found little that was encouraging amongst any of them. If we are to believe Clarendon, he was betrayed by one of those in whom he most trusted, Sir Richard Willis, who was high in the confidence of Charles, but was at the same time a paid spy of Cromwell's. It is certain that one day in March the Protector said to Lord Broghill, "An old friend of yours is in town, the Duke of Ormond, now lodged in Drury Lane, at the Papist surgeon's there. You had better tell him to be gone." Broghill found that this was the case, and gave Ormond the necessary hint, who hurried back to Bruges, and assured Charles and his Court that Cromwell had many enemies, but there was at present no chance of a successful invasion.
