The Donbas is feeling the brunt of the recent Russian military failures.

Biggest win since WW2': The site where Ukraine says it killed 'hundreds' of Russians after botched plan

Ukraine news live: Russia says Azovstal steelworks fighters have surrendered

Their residents are being terrorised. Families are being split. People are being killed and maimed and tens of thousands are running for their lives.

Severodonetsk in Luhansk is the last Ukrainian pocket of resistance and the Russians want this city so they can complete their capture of the whole of Luhansk and then move on to Donetsk.

The country's president, Volodymyr Zelenskyy, says the twin areas of Luhansk and Donetsk in eastern Ukraine are being "turned into hell". He's right. They are.

The towns and cities here are being pummelled; homes and businesses are being smashed by this war.Their catastrophic attempt to cross the Donets River at Bilohorivka village recently to encircle Severodonetsk and grab the whole of Luhansk, has meant a dramatic rewrite of the military plan. 

And the redrafting means shifting tactics and upping the tempo.

The Ukrainian military has allowed few on the ground on the site of what it claims is its biggest military victory since the Second World War.

We were led through forest routes by Ukrainian military guides to the area which will go down in Ukrainian military history books as a key strategic victory against their much bigger enemy.

The area is now a graveyard of Russian military vehicles.

'Some sort of suicide club'

There's spent ammunition cartridges, unexploded ordnance, grenades and burnt-out hulks of army transporters spread over the scorched farmland on the western side of the river.

It's here the Ukrainians say hundreds of Russian soldiers died in a botched plan.

They attempted to build pontoon bridges across the river using smoke as a cover but the Ukrainians were waiting and launched a fierce defence - showering what they say was a Russian battalion, wiping out an estimated 70 vehicles and hundreds of troops.

"It seems like they were some sort of suicide club or their commanders didn't care for them," Yuri tells us.

"It's strange. They just sent them to die… and they followed stupid, stupid orders from their commanders."

The bodies had been cleared away by the time we were allowed access, so it's difficult to verify the numbers killed, but there was certainly a ferocious attack here.

The impact has been to bolster Ukrainian morale whilst also apparently sparking real substantial criticism of the Russian leader himself, Vladimir Putin.

It also seems to have pressurised the Russians into changing tactics.

After the failures to encircle the capital Kyiv or the country's second city Kharkiv, the humiliating disaster at Bilohorivka has prompted a change in direction.
