On a Sunday morning in July 1980, the Hollinwell Showground in Kirkby-in-Ashfield was alive with the bustle of an English summer day. The sun poured its warmth over the assembled crowds, casting a golden glow over the green fields. Children, dressed in the vibrant regalia of marching bands, were the stars of the show — ribbons fluttering, drums beating, and the air filled with the excited chatter of young voices. It was the kind of day that seemed to promise nothing but the simple joys of community and tradition.

But by late morning, something shifted. The ordinary became uncanny, the bright day turned dark, and Hollinwell would forever be remembered for what happened next.

A morning like any other — until it wasn’t

The scene was set for a quintessentially British affair: the annual Hollinwell Show, where the Forest League of Juvenile Jazz Bands gathered for a competition that drew children from across the East Midlands. The showground buzzed with the energy of anticipation. Parents, cameras poised, watched as their children lined up, their excitement palpable.

But then, at just after 10:30 AM, the excitement turned to confusion. One child collapsed, then another, and soon the field was strewn with children falling like dominos, their bodies betraying them in ways no one could understand. What began as a promising summer day quickly transformed into a nightmare.

“(…) like a battlefield with bodies everywhere” — An officer who responded to the scene

The mysterious collapse

Eyewitnesses would go on to describe the scene with a surreal horror. “They fell down like ninepins,” one person remarked, struggling to articulate the speed and breadth of the event. The children, some as young as five, were suddenly incapacitated — dizziness, nausea, sore eyes, and the pervasive sense that their limbs had turned to jelly. One girl would later say, “My legs and arms felt as if they had no bones in them.”

“I went all weak and got pains in my stomach and then I fainted. Everyone was falling down and some were crying. My stomach was all tight and aching. I felt better when I came ‘round in hospital.” — Kerry Elliot, 10.

“She came in and said ‘Mummy, I don’t feel very well’. She was frothing at the mouth. Her eyes were running.” — Ann, the mother of one of the affected children.

Within minutes, the joyous noise of the morning had been replaced by the wail of ambulances and the panicked cries of parents searching for their children in the growing tumult. In total, around 300 people, including adults and even infants, succumbed to the strange affliction that day. The sight was so overwhelming that it seemed to evoke a collective sense of dread, a kind of primal fear that something unnatural was at play.

Emergency response & the aftermath

“One of the biggest frighteners was that many ambulances. People hadn’t seen so many since the Second World War.” — Ken, a grandfather of one of the affected children.

The response was swift but laden with uncertainty. Ambulances ferried the afflicted to nearby hospitals. Children were treated for vomiting, fainting, and respiratory issues, with nine being kept overnight. But no one knew why they had fallen ill, only that something had gone terribly wrong.

As the day wore on, authorities scrambled for answers. Theories abounded — food poisoning, tainted water, even an unusual wave of radio frequencies — but none seemed to stick. Some witnesses claimed the grass looked blue, and the air smelled like onions. The showground itself became a crime scene of sorts, with investigators combing through the detritus of the day, searching for a clue that might explain the mass collapse.

Theories and speculations

As the children fell, the immediate reaction was to find a cause — something tangible, something that could be controlled. The first thought was food poisoning. Perhaps something in the ice cream or the water had triggered this mass collapse? Urgent announcements were made over the public address system, warning people not to consume anything until the source of the problem was identified. But this explanation quickly began to unravel. Many of the children had brought their own food and drink from home, and tests on samples from the showground revealed no contamination.

With food poisoning ruled out, attention turned to another possible culprit — a chemical cloud. The theory that the children had been exposed to a pesticide or some other airborne toxin gained traction. Headlines screamed of a “Gas Cloud KOs Children,” and the idea that something invisible and insidious had drifted over the showground began to take hold. But even as this theory took shape, it didn’t hold well to many. The farmer operating in the area confirmed nearby fields hadn’t been sprayed in years, and other local investigations failed to link any chemicals to the incident. Moreover, according to the Nottinghamshire Fire Service, the wind on that day had been blowing in the wrong direction to carry fumes toward the showground.

Contemporary press coverage of the Hollinwell collapse

Other sources claim the opposite. Findings from the BBC in 2003 revealed the local use of the pesticide tridemorph. However, this comes 20 years after the event, and disagrees with official findings. The official inquiry at the time revealed the use of Calixin, a pesticide that contains tridemorph, but it was not considered to be dangerous at the time. It’s worth nothing that for years, Tridemorph was sprayed across England and around the globe without any similar incident. Commonly used on cereal crops, it’s known to cause skin and eye irritation.

The official explanation

As the investigation deepened, the authorities began to entertain a more troubling explanation: mass hysteria. It was a term that provoked immediate anger and defensiveness from the families involved. The idea that the children’s symptoms were not caused by any physical agent but rather by a collective psychological response was met with disbelief and outrage.

It was an uncomfortable conclusion, one that didn’t sit well with many of the affected families. How could hysteria explain the physical symptoms — the vomiting, the foaming at the mouth, the sore eyes? And how could it account for the fact that the collapse seemed to affect so many, so suddenly, and with such a set of symptoms?

The official explanation, while neat, was far from satisfying for the eyewitnesses. Those who were there insisted that the symptoms were real, tangible, and too severe to be dismissed as mere imagination. They spoke of the oppressive heat, the strong smells in the air, and the strange sense that something had poisoned the very atmosphere of the showground.

“My daughter was home two hours before she was took poorly. So, where’s your theory there?” — Ann

An ongoing mystery & unanswered questions

Over four decades later, the Hollinwell Incident remains an unsolved mystery. Official records have disappeared, leaving a void where answers should be. Families continue to live with the consequences, some still grappling with long-term health issues that they attribute to that fateful day. And while the story has been revisited by journalists and researchers, the truth remains frustratingly elusive.

Was it truly a case of mass hysteria, a psychological phenomenon writ large across the canvas of a summer’s day? Or was there something more tangible, more dangerous, lurking in the air at Hollinwell? Some suggest that the answers might never be found, that the incident has become one of those enigmas that resist resolution, leaving only questions in their wake.

“The whole thing is a complete mystery. A gymkhana was held in the same field later without trouble.” — Dr John Wood, director of health for the Kirkby area. He posits mass hysteria as the most likely cause.

In considering the Hollinwell Incident, I can’t help but speculate. Was it truly mass hysteria so severe that it sparked mild to severe physical symptoms in almost 300 children? Or was it a chemical assault, accidental but no less harmful, that left these kids crumpled on the ground?

And then there’s the more unsettling possibility — that something else entirely happened that day, something we’re not equipped to comprehend. As some of the more far-fetched theories suggest, was it something paranormal, an unexplained phenomenon, an event that defies our conventional understanding of the world?

Where do we go from here?

What do you think? Is there a piece of the puzzle that everyone has missed, a detail overlooked in the rush to provide answers? Was it genuine mass hysteria? Toxic gas, pesticides, radio waves? Aliens? Or is this just one of those stories that will forever remain in the realm of the unknown, a modern-day mystery to be pondered but never solved?
