Miles Sindercombe was a fascinating surprise to me as I researched my book, Sharavogue. I was looking for any assassination attempts on the Lord Protector Oliver Cromwell in the mid-17th Century, because my protatonist would be attempting to do exactly that. Being American, I had never heard of Sindercombe, so I wonder if he is better known in the UK. He tried twice and failed to kill this uncrowned king. Wikipedia gives a pretty good history of assassination that's worth the read, tracing it back to 1080 and the Order of Assassins founded around the time of the Crusades. In Cromwell's case the attempt must have come as no surprise, at least to his security crew, considering Cromwell had won a bloody civil war and then beheaded the king, Charles I. He also had led a brutal march across Ireland to put down a rebellion. The man did not lack for enemies and controversy over him continues to this day.
What's interesting is that Sindercombe seems to be an unlikely and tragic figure. I was unable to turn up an illustration of him, but it seems he was a thin, mild-mannered sort who went by the name of "Fish." A former soldier, apprentice to a surgeon, he aligned with others he met in taverns (i.e. Edward Sexby) who had fought against the Royalists but had fallen out with Cromwell's policies.
The first plan against Cromwell was to shoot up his carriage as it slowed to go through a narrow pass on the way to Hampton Court. But, Cromwell decided to go by boat so the plot failed. The second attempt was to shoot Cromwell from the window above the side exit from Westminster Abbey where Cromwell would pass after hearing a sermon. But Crowell was surrounded by crowds, they could not get a good shot, and the plot was discovered. Sindercombe and his accomplices were arrested. Sexby was questioned by Cromwell himself, was sent to prison and soon died of a fever. He was the lucky one. Sindercombe was sentenced to a traitor's death (the whole hideous bit, with the hanging, disembowelling while still alive, and body parts on pikes for display). To help him avoid this, friends sent him letters coated with arsenic which he rubbed on his face and neck, poisoning himself to death the night before his planned execution. His body was buried beneath the highway where no one could mourn him.
Cromwell made light of the whole thing, calling such attemps on his life "little fiddling things," so as not to encourage the Royalist-spread rumor that he so feared assassination he was drinking himself to death. My recent visit to the Cromwell Museum in Huntingdon confirms the rumor of his fear, if not the drinking. A display shows an inlaid cabinet of perfumes, ointments and soaps--a gift from the Grand Duke of Tuscany--that he never used, most likely fearing a poison. Cromwell's doctor is quoted as saying "He is possibly afraid that they will be bitter, being fearful of his own shadow, so to speak, and living in constant apprehension of everything for he trusts no one."
History has Cromwell dying of natural causes in 1658, but after his death his own doctor, secretly (or suddenly?) a Royalist, was rumored to have poisoned him in favor of the return to monarchy.
Following the American Civil War, President Abraham Lincoln was not so fortunate. His life is revisited in the new movie, Lincoln, just out this week. His assassin John Wilkes Booth was trapped in a burning barn and shot by a US cavalry officer, and died from the wound hours later. It is an unforgettable episode in our history, unfortunately repeated several times.
