For over a century, a group of stylish, sharp-witted women in London pulled off some of the most audacious heists, ran blackmail rackets, and sowed chaos in the most refined of places. They were known as the Forty Elephants—an all-female crime syndicate that struck fear into shopkeepers, scandalised high society, and humiliated the police—all while dressed to kill, quite literally.
Over a hundred years later they are the inspiration behind the gritty London drama series A Thousand Blows.

The Rise of the Forty Elephants

The Forty Elephants (sometimes called the Forty Thieves) took their name from the Elephant and Castle district of London, a rough-and-tumble part of the city that has long been a breeding ground for criminal enterprises. While records suggest that they had been active since at least the 1870s, some sources hint at even earlier origins. However, it was in the late 19th and early 20th centuries that they became a formidable criminal force.

Operating as a sister organisation to the infamous Elephant and Castle Gang (a male-run criminal outfit), the Forty Elephants weren’t just petty pickpockets—they were professionals. Their criminal empire revolved around large-scale shoplifting operations, which were conducted with the kind of organisation that would put today’s corporate logistics teams to shame.

How They Pulled It Off

The Forty Elephants specialised in shoplifting high-end goods from London’s most prestigious department stores. Harrods, Selfridges, and Liberty were all victims of their audacious heists.

Their technique was as simple as it was effective: gang members would enter a shop in small groups, distracting sales assistants while others stuffed expensive jewellery, silks, furs, and perfumes into hidden pockets sewn into their skirts and coats. Their clothing was custom-made for theft, allowing them to smuggle out an entire store’s worth of stock in broad daylight.

They also used an early form of identity theft. Some members, pretending to be rich socialites, would open store accounts under false names, order expensive items, and then vanish before payment was due. Others blackmailed wealthy men by seducing them and then threatening to expose their affairs, a lucrative sideline that made the Forty Elephants feared both in the shops and in high-society drawing rooms.

Mary Carr: The First Queen of the Forty Elephants

The rise of the gang as a true syndicate owes much to Mary Carr, the original queen of the Forty Elephants. Born in the 1800s, Carr was a tactician with a velvet glove and a steely resolve. She didn’t just steal—she orchestrated. Under her early leadership, the gang moved from opportunistic shoplifting to a structured, hierarchical operation with codes of conduct, designated territories, and loyalty enforced with whispered threats and sudden violence.

While little survives in writing about Carr’s personal life, her legacy is inked into the gang’s golden age. She laid the blueprint for female-led organised crime—turning desperation into discipline, and shoplifters into soldiers.

Her successor: Alice Diamond

By the 1920s, the gang had a leader who would go down in criminal history—Alice Diamond, better known as “Diamond Annie.” Born in 1896 in Southwark, Alice was tall (around 5’10”), imposing, and known for wearing an impressive collection of diamond rings, which she reportedly used as makeshift knuckle-dusters in fights.

Alice transformed the Forty Elephants from a loosely connected gang of thieves into a ruthlessly efficient crime syndicate. Under her leadership, the group expanded its operations beyond London, targeting wealthy cities across the UK, including Manchester and Birmingham. She also introduced a strict code of discipline—if a gang member broke the rules, they would face severe consequences.

One of Alice’s most daring heists involved storming a West End jewellery store in broad daylight. Using brute force, distraction, and sheer audacity, the gang made off with thousands of pounds worth of goods before the police even knew what had happened. When Alice was eventually arrested in 1925, it was for violent conduct rather than theft—her reputation as a formidable fighter was well-earned.

Beyond Diamond Annie: The Evolution of the Gang

After Alice was sentenced to prison, leadership of the Forty Elephants fell to Maggie Hill, another fearsome operator who kept the gang going strong into the 1940s. Maggie, incidentally, was the sister of the infamous gangster Billy Hill, a key player in London’s criminal underworld.

Under Maggie’s rule, the gang adapted to the increasing difficulties of shoplifting as stores improved security measures. They moved into burglary, fraud, and blackmail, with some members even marrying into the criminal elite to secure their positions.

By the mid-20th century, however, changing social conditions and tougher policing made it harder for the Forty Elephants to operate at their former levels of success. Increased use of surveillance, better-trained shop assistants, and improved policing meant their era was coming to an end. By the 1970s, the gang had largely faded into history.

The Forty Elephants on Screen: A Thousand Blows

Their criminal legacy might have slipped into obscurity—were it not for a burst of modern interest that brought them back into the spotlight. One of the most high-profile tributes? Steven Knight’s 2023 drama series, A Thousand Blows.

Set in Victorian London’s East End, A Thousand Blows is a brutal, stylish reimagining of the city’s boxing underworld—but woven into its heart is a powerful thread of inspiration drawn directly from the Forty Elephants. Chief among them is the character Mary Carr, played with knife-edged menace and magnetic control by Erin Doherty. She is based on the real-life Mary Carr, though the series gives her a broader, bloodier canvas to rule.

The show doesn’t romanticise Carr’s leadership—it sharpens it. She’s portrayed as a ruthless strategist in a man’s world, building an underground female empire while her male counterparts brawl in sawdust-strewn rings. The spirit of the Forty Elephants is captured not just in the plot but in the aesthetics: the subversive use of fashion, the weaponised charm, the coded sisterhood.

Where Peaky Blinders swaggered in flat caps and razors, A Thousand Blows delivers its punches in corsets and cunning. It reframes the idea of criminal power, showing how women like Carr didn’t just survive in the underworld—they thrived, innovated, and dominated it.

A Legacy of Infamy

The Forty Elephants remain one of the most remarkable gangs in British criminal history—not because they were women, but because they were better. Better organised, better dressed, and often better at getting away with it than their male rivals.

Their legacy is one of elegant defiance. They didn’t just break the law—they rewrote the rules. Led first by the shadowy brilliance of Mary Carr, and then the steel and spectacle of Alice Diamond, the Forty Elephants were more than a gang. They were a movement. A phenomenon. A criminal matriarchy in pearls.

And now, thanks to A Thousand Blows, their story is being retold for a new generation—proof that in the annals of crime, sometimes the sharpest minds wear heels.
