Ukraine's risky gamble in Bakhmut may be paying off as infighting in Russia's ranks threatens its hopes of capturing the city, experts say

• Ukraine has defended Bakhmut from Russia for months, despite some calls to focus elsewhere.
• The battle has hurt Russian forces, and Wagner Group mercenaries are threatening to pull out.
• If they go through with it, Ukraine's risky gamble might just pay off, experts say.

Russia's months-long campaign to capture the eastern Ukrainian city of Bakhmut has relied heavily on efforts from the notorious Wagner Group. But Yevgeny Prigozhin, the leader of the paramilitary organization, is now suggesting that his private army of mercenaries may soon be abandoning the fight.
