1940: Leon Trotsky Assassinated by Soviet Agent in Mexico

Leon Trotsky, Russian revolutionary and founder of the Red Army, was attacked at his fortified home in Coyoacan, Mexico City, on 20 August 1940. The attacker, Ramon Mercader, was an undercover agent of the Soviet secret police, the NKVD, who had spent months gaining the trust of those in Trotsky's inner circle.

Mercader struck Trotsky with an ice axe, inflicting a fatal wound to the skull. Trotsky died the following day, aged 60. Mercader was arrested at the scene, convicted of murder, and served 20 years in a Mexican prison. He was later awarded the Hero of the Soviet Union medal by Stalin.

1960: Francis Gary Powers Pleads Guilty at Moscow Spy Trial

On 17 August 1960, American pilot Francis Gary Powers stood trial in Moscow after his U-2 reconnaissance aircraft was shot down over Soviet airspace on 1 May 1960. Powers, flying a CIA surveillance mission, had been captured alive when his high-altitude spy plane was struck by a Soviet surface-to-air missile near Sverdlovsk.

Powers pleaded guilty to espionage charges before a Soviet military tribunal, in a trial that became a Cold War spectacle broadcast to the world. He was sentenced to ten years, serving nearly two before being exchanged for Soviet spy Rudolf Abel at the Glienicke Bridge in Berlin in February 1962.

1751: The Poisoning of Francis Blandy by His Own Daughter

Francis Blandy, a lawyer and town clerk of Henley-on-Thames, died in August 1751 after his daughter Mary repeatedly dosed his food with arsenic. The powder had been supplied by her lover, Captain William Henry Cranstoun, a Scottish officer who was already secretly married. Cranstoun told Mary the powder would make her father more accepting of their betrothal. His death became one of the earliest criminal cases to feature scientific toxicological evidence.

Mary was arrested after servants and relatives raised suspicions. Tried at Oxford in February 1752, she was convicted of murder and hanged on 6 April 1752, protesting her innocence to the end. Cranstoun escaped justice in court but died of illness in December 1752.

1964: The Last Two Men Hanged in Britain, Executed Simultaneously 50 Kilometres Apart

At 8:00 a.m. on 13 August 1964, two gallows traps opened in unison across England. Peter Anthony Allen dropped at Walton Prison in Liverpool; Gwynne Owen Evans dropped at Strangeways Prison in Manchester. Both had been convicted of the capital murder of John Alan West, a 53-year-old laundry van driver from Workington, Cumbria, stabbed and beaten to death during a robbery at his home in the early hours of 7 April 1964.

Police traced the men within 48 hours through a medallion left at the scene, inscribed with Evans' name. Tried together at Manchester Crown Court in June 1964, the jury found both equally guilty of capital murder committed in the course of theft. The judge, executioners Harry Allen and Robert Leslie Stewart, and the clock itself were all synchronised. When the traps fell, Britain's era of capital punishment fell with them. No one has been executed in the United Kingdom since.
