Another amazing theory being discussed by Russian sources.
The Russia Army encouraged Wagner to attack Bakhmut knowing that it would suffer massive casualties. But they didn't think Wagner would actually be able to take the city. Now that they have, they have a big problem.
Wagner are withdrawing and handing over Bakhmut to the Russia Army, But knowing that its completely untenable and will soon be surrounded by Ukraine. The Russian Army knows this but the alternative is to let Ukraine literally walk back into the city.
Prigozhin takes the glory for taking Bakhmut leaving the Army to take the disgrace of losing it at some stage in the future.
Civil War creeps closer.
