“There certainly can be no doubt,” wrote a Venetian diplomat late in the rule of Oliver Cromwell, “that Charles [II] is betrayed by some of those who stand about him, otherwise it would be impossible for Cromwell to find out the secret plans he meditates.”
And indeed, on this date* in 1655, just such a one was shot by the exiled royalists as a Protectorate spy.
Henry Manning, the son of a royalist colonel who died fighting for Charles’s late beheaded father, had impeccable credentials for the Stuarts. The alleged English king was now parked on the continent, trying to conjure up some route back to the throne.
So when the pedigreed Manning turned up at exile camp, packing “a considerable sum of money” he was willing to give to the cause, he was welcomed with open arms.
While royalist courtiers blabbed, Manning was filing enciphered reports for Cromwell’s spy chief (and the source of that considerable sum of money) John Thurloe. And these reports disclosed royalist collaborators in England who were rounded up in great numbers in 1655 — a year in which Cromwell dissolved parliament and resorted to direct military rule, growing correspondingly more worried about plots against his person.
It seems that Cromwell’s intelligence men lacked a certain subtlety, however. After an English traveler illicitly met with Charles on the continent during the dead of night, and was picked up for questioning when he returned to the island, the Stuart men naturally reasoned that only the small handful of people involved in that meeting could have been the mole. Manning was done for as soon as his apartments were searched.
Under interrogation, Manning gave up everything he knew, trying desperately to save his skin by offers of turning double-agent and exploiting his relationship with the Protectorate for the royalists’ benefit.** As late as December 14 the captured spy — hearing “sad rumours of a sudden end intended me, nay, to-morrow morning” — addressed a letter to royal aide Edward Nicholas, “humbly crav[ing] you would once more try his most gratious Majesty.”
His Majesty’s concern, however, was of fading into ridiculousness and irrelevance, and the play here was to make an example of treachery. Without apparent legal sanction — the word of the shadow king Charles was law enough here, and his German hosts were content to look the other way — Manning was pistoled to death in a woods outside of Cologne, and the fact made known abroad.
Everyone who’s had a look at Henry Manning agrees that the guy was a small and abject man, easy prey for these great ministers of state. But then, when Thurloe himself was arrested for treason upon the monarchy’s eventual restoration, he procured his own parole by spilling his secrets to King Charles.
* The Gregorian date, per the Holy Roman Empire where Manning was shot — not the Julian date still in use in England. Note as well that the 15th is the most readily inferred date from the available evidence, particularly Manning’s letter of the 14th, but that the event itself does not appear to have been affirmatively recorded on this (or any) specific date by contemporaries. There’s little room for variance, as correspondents are commenting on the death of Manning by the end of December.
