After more than three weeks of relentless burning and two days of military deployment, there is genuine optimism that the massive wildfire tearing across the hillside above Blaenavon may finally be losing its grip.
Firefighters and soldiers have spoken of an exhausting fight against a deep-seated peat fire that has consumed over 4,000 hectares — roughly 9,800 acres — threatening homes, livestock and farmland throughout the Eastern valley. The operation marks the first time UK armed forces have been called in to tackle wildfires since 2018, after South Wales Fire and Rescue Service requested military assistance amid a weekend that saw at least 13 separate blazes ignite across the valleys.
Nationally, around 36 fires remain active, with 11 now classified as major incidents. A punishing combination of extreme heat, prolonged drought and the escalating climate crisis has produced the busiest wildfire season on record for the UK.
A fire that refuses to die
Jamie Windsor, group commander at Ebbw Vale station, knows the Welsh hillsides better than most. But even three decades into his career, nothing prepared him for the ferocity of this particular inferno.
The problem, he explained, lies beneath the surface. Layers of peat buried under the orange and purple heather on the Blaenavon hillside have turned the fire into a subterranean enemy.
“It burns very deep, the peat, and because it’s been so hot, it’s not cooling down at night. You think you’ve got a handle on it but it’s burning underground and it just pops up again somewhere else,” Windsor said. “We’ve got a lot of wildfire experience here in south Wales but I’ve never seen anything like it in 30 years.”
During a visit to the scene on Sunday, soldiers from the Queen’s Own Gurkha Logistic Regiment were digging firebreaks and turning over smoking soil by hand, trying to deny the flames fresh purchase. Small flames licked at the base of blackened trees just metres from where they worked. In another section of woodland, several trees ignited without warning, bursting into flame within seconds.
An aerial assault
Higher up the ridge, a civilian-contracted helicopter clawed water from a vast plastic pool fed by a local dam, circling again and again to douse reigniting pockets on the smouldering hillside. The smoke has drifted far beyond Blaenavon itself — visible from Cardiff and as far east as Gloucestershire.
Firefighters from across the UK have converged on the town, improvising ways to deliver water to the most inaccessible terrain. An old steel mill on the edge of town has been converted into a makeshift forward command post. New thermal-imaging drones and bespoke response vehicles, designed by South Wales Fire and Rescue Service specifically for this kind of scenario, have come online just in time.
“The drone means we can be much more accurate with pinpointing where we need to go, and it keeps our teams safer,” said Darren Cleaves, group manager for the service, as he radioed a colleague stationed at the fire’s perimeter. “Just in time.”
The combined operation appears to have spared the houses on the edge of Blaenavon. On Llanover Close, the last road before the village meets the hillside, residents have watched a steady procession of fire engines, water tankers and tractors trundle back and forth along the forestry track above their homes for weeks.
Cindy Rogers, 60, occupies the final house on the street. She remembers a 2004 fire that started near the summit and crept dangerously close to her garden. She gestures towards the still-visible fire line on the ridge.
“It’s a worry that this is going to get worse in the future with climate change, but I wouldn’t move unless I really had to,” she said. “All it takes is the wind to change direction and that’s it.”
The human cost and the hunt for answers
By Sunday afternoon, there were encouraging signs. Fin Monahan, chief fire officer of South Wales Fire and Rescue, said the Blaenavon blaze appeared to be slowing at last.
“It’s been very tough, but I’m so proud of the professionalism of these teams and how hard they are working,” Monahan said. “Morale is still high, everything is calm and controlled … It’s just the scale of what we’re dealing with is unprecedented. We normally get about 1,000 999 calls a week, and at the moment it’s 7,000.”
Arson, he warned, has been a significant driver of this summer’s devastation. “Not every investigation has been completed yet but we can already see it’s been a significant issue this year in south Wales. Fire safety education is another key area we focus on … Driving home last night, I saw smoke and I went and found a guy burning tyres and other stuff in his garden, under a tree. I had to tell him to put it out.”
The cause of the Blaenavon fire remains undetermined. Elsewhere, arrests are mounting. On Saturday, four teenage boys from Porth in the Rhondda valley were detained on suspicion of arson before being released on bail. In Stoke-on-Trent, a man and woman were arrested in connection with a fire that destroyed four homes. A man in King’s Norton and another in east London have also been arrested on suspicion of arson with intent to endanger life.
A summer of extremes
The UK has endured repeated heatwaves this summer, conditions that scientists link directly to climate breakdown. Last month, the entirety of Wales and nearly three-quarters of England were officially declared in drought. The Met Office confirmed this week that the country is on course for its hottest summer on record by average temperature.
Yet the relief the nation craves — cooler temperatures and sustained rainfall — may bring fresh problems of its own. The Met Office cautioned on Saturday that autumn downpours are not guaranteed to undo months of drought. And the same climate patterns that parched the land are now pointing towards a supercharged El Niño, forecast to deliver a wet and stormy winter.
In Blaenavon, residents are already bracing for what comes next. An 89-year-old man who has lived on Llanover Close since the street was built, and who asked not to be named, described a creeping dread.
“It’s the flooding that worries me. My basement flooded last winter,” he said. “Fire and flood … I never thought it would come to this.”
Why it Matters
The battle above Blaenavon is no longer simply a local emergency — it is a warning shot. A wildfire that demands military intervention, overwhelms the national 999 system sevenfold, and burns for more than three weeks on British soil signals a fundamental shift in the country’s relationship with fire. With arson compounding the climate-driven crisis, and drought conditions refusing to ease, the question is no longer whether the UK can handle another summer like this one, but whether it can afford one.
