Russia's grinding more than five months-long push to try to take Bakhmut has puzzled some Western military analysts who have said that heavy losses incurred on the Russian side and the fact that Ukraine has built defensive lines to fall back to nearby mean any Russian victory there, if it happens, would be pyrrhic.
Comment: These analysts might be less puzzled if they asked themselves why NATO-Ukraine was sacrificing so many of its forces in their failing attempt to retain Bakhmut; evidently whatever is there is deemed worth the battle.
Yevgeny Prigozhin, founder of Russia's Wagner mercenary group which is fighting in the battle of Bakhmut, set out in detail on Saturday why he thought its capture would be significant.
"The cherry on the cake is the system of Soledar and Bakhmut mines, which is actually a network of underground cities. It not only (has the ability to hold) a big group of people at a depth of 80-100 metres, but tanks and infantry fighting vehicles can also move about."
Prigozhin, who would likely see his political capital in Moscow boosted if Bakhmut fell to Russia given Wagner's role in the fighting there, said stockpiles of weapons had been stored in the underground complexes since the first world war.
His comments were a reference to vast salt and other mines in the area which contain more than 100 miles of tunnels and a vast underground room which has hosted football matches and classical music concerts in more peaceful times.
A White House official said on Thursday that Washington believed Prigozhin wanted to take control of salt and gypsum mines in the area for commercial reasons. It made no mention of their alleged subterranean military use.
Comment: That the WH failed to mention the potential military use is in itself revealing. We know that Ukraine has done something similar before such as with the Azovstal factory: Secrets of the command bunker underneath Azovstal revealed in Russian media reports
Prigozhin, who is sanctioned in the West, cited other advantages of taking Bakhmut, calling it "a serious logistics centre" with unique defensive fortifications.
He made his comments on his press service's Telegram channel as shellfire echoed around Bakhmut's near-deserted streets on Saturday despite a self-declared Russian ceasefire to mark Orthodox Christmas, something Kyiv rejected as a ploy.
Bakhmut, which Russia calls Artyomovsk, is the focus of the most intense fighting in Ukraine, and Prigozhin made his comments as another Telegram channel associated with Wagner claimed Russia had captured a strategically important settlement on Bakhmut's outskirts.
Reuters could not independently verify the assertion.
The Russian defence ministry earlier on Saturday reported fierce fighting in eastern Ukraine.
A Ukrainian defence ministry spokesman said the town of Soledar, which is near Bakhmut and hosts a salt mine, was still under Ukrainian control despite what he described as fierce Russian assaults.
These Ukrainian under ground cities are used for human trafficking, satanic rituals, organ harvesting and the real sad part is most of the victims are very young children. That is why Bribem and his government are giving Ukraine trillions to keep their dirty little secrets because they get millions in return and the war must go on. Human trafficking a multi billion dollar profiting business on the backs of children, Putin is there to put an end to the Kharzarian Zionist Mafia Nazis.
