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.

On August 20, 1986, part-time mail carrier Patrick Sherrill walked into the post office in Edmond, Oklahoma, and opened fire on his colleagues, shooting 20 people and killing 14 before turning the gun on himself. It was the first mass shooting by an individual in a US office workplace environment, and it sent shockwaves through American working life.

The massacre gave rise to the phrase ‘going postal’, a term for sudden, explosive workplace rage. Between 1970 and 1997, more than 40 people were killed by current or former postal employees in at least 20 separate incidents, cementing the phrase in the English vocabulary.

On the evening of 24 April 1878, drover J. Fisher McMichael was washing himself at a camp near Bundaberg when Sam Ah Poo, the cook on his droving run, struck him from behind with an axe. The blow opened a gash four inches long beside the backbone. As McMichael fell, Ah Poo swung twice more, shouting ‘I killoo you now, you no killeemo.’ McMichael survived only four hours. One of the drovers wrestled Ah Poo to the ground; when bound, Ah Poo appeared entirely calm, described by a witness as like one who had got a load off his mind.

Tried at the Toowoomba Winter Assizes on 22 July 1878 before Justice Lilley, Ah Poo’s defence argued insanity and delusion. The jury disagreed, returning a guilty verdict after thirty minutes. On the morning of 19 August 1878, Ah Poo walked to the scaffold at Toowoomba Gaol with firm steps, requiring little support from the warders. The bolt was drawn at eight o’clock and death followed almost instantaneously.

John Wesley Hardin was one of the most feared gunfighters of the American Old West. Born in Texas in 1853 to a Methodist preacher, he killed his first man at 15 and spent the following decade evading lawmen across the South. Sentenced to 24 years for murder in 1877, Hardin claimed to have killed 42 men, though historians estimate the true figure exceeded 20. He studied law in prison and wrote a self-aggrandising autobiography, widely noted for its exaggerations.

Within a year of his 1894 release, Hardin was shot dead by constable John Selman in the Acme Saloon in El Paso. Hardin had been gambling, rolling dice at the bar, and his last words were reportedly “Four sixes to beat.” Moments later, Selman walked up behind him and shot him in the head. Hardin was 42 years old.
