1658: John Hewett and Henry Slingsby, royalists

On this date in 1658, two royalist conspirators were beheaded at Tower Hill for plotting against Oliver Cromwell‘s Protectorate.

At this very late date, conflicts within the Lord Protector’s state raised the hopes of the exiled royal claimant Charles Stuart for a successful invasion. (Little did the imminent King Charles II suspect that Cromwell himself would die suddenly three months hence, collapsing the revolutionary government.) Plots and counterplots, spying and betrayal, were the order of the day; it was the bad luck of our men to set theirs in motion just a shade too early, but perhaps it was Charles Stuart’s good luck that Team Cromwell smashed it before it could ripen into a premature commitment of forces.

For the particulars, we turn to parliamentarian cavalryman and politician Edmund Ludlow, a regicide who had thirty-odd years cooling his spurs in continental exile during which to scribble his memoir of the grand experiment.

Another plot much more dangerous was about the same time carried on by the Royalists, and discovered to him by his spies. The persons concerned in it he used with more severity, because he accounted them to be of a more formidable party, and therefore referred them to be tried by those persons whom his last Assembly had nominated to be a High Court of Justice.

The prisoners were Dr. Hewet [John Hewett, onetime chaplain to King Charles I and an open royalist], Sir Henry Slingsby [a Yorkshire politician and Royalist veteran of the civil wars], and Mr. Mordaunt [eventually made a viscount by Charles II in recognition of his efforts on behalf of restoration], with some others of the meaner sort. The general charge against them was for endeavouring to levy war against the Government on the behalf of Charles Stuart.

The particular charge against Dr. Hewet was for dispersing commissions from the son of the late King, and perswading divers to raise forces by virtue of the same. That against Sir Henry Slingsby was for attempting to debauch some of the garison of Hull to the service of Charles Stuart, and delivering a commission from him to them. The prisoners of less note were charged with a design of firing the city in several places, at the time appointed for their party to be in arms.

Dr. Hewet being brought before the Court, moved that he might be tried by a jury, and demurred to the jurisdiction of the Court. But the Court over-ruled his demurrer, and told him, that unless he would plead to his charge, they would cause his refusal to be entred, and proceed against him as if the fact were confessed. This being twice said to him, he was required the third time to plead: to which he answered, that if the Judges would declare it to be according to law for him to plead, he would obey: but he was told that the gentlemen then present were his Judges, and that if he would not plead they would register his contempt the third time, and upon his refusal did so.

Mr. Mordaunt admonished by his example, pleaded not guilty; and after a full hearing of the witnesses on both sides, the Court acquitted him by one voice. Then Sir Henry Slingsby was called to the bar, and the witnesses on each side being heard, he was pronounced guilty, tho in the opinion of many men he had very hard measure. For it appeared that he was a prisoner at the time when he was charged to have practised against the Government; that he was a declared enemy, and therefore by the laws of war free to make any such attempt; besides it was alledged that the persons, whom he was accused to have endeavoured to corrupt, had trapan’d him by their promises to serve the king in delivering Hull, if he would give them a commission to act for him, which commission was an old one that had long lain by him. But all this being not thought sufficient to excuse him, he was adjudged to die.

The rest of the prisoners were also condemned, and sentence of death being pronounced, Sir Henry Slingsby and Dr. Hewet had the favour of being [June 8] 1658 beheaded; and the others, being men of a lesser figure, were hanged.

Cromwel’s daughter and favourite Mrs. Cleypole [Elizabeth Claypole, who was reputed to intercede frequently with her father on behalf of royalists], laboured earnestly with her father to save the life of Dr. Hewet, but without success: which denial so afflicted her, that it was reported to have been one cause of her death, which happened soon after with the concurrence Aug. 6. of an ulcer in her womb.

We have also an account of the dying behavior of both Slingsby and — much more detailed — Hewitt, each of whom slated the injustice of their sentence as having greatly exaggerated their “treasonable” designs.
