The Don is a much bigger river than the Rubicon, but Yevgeny Prigozhin and his army crossed it anyway on Friday.
Not being classically educated, the boss of the Wagner mercenary army probably did not mutter alea iacta est to himself -- "The die is cast" -- as Julius Caesar reportedly did when he crossed the Rubicon and launched his rebellion against the Roman Senate in 49 BC. But Mr Prigozhin is now on the same Death or Glory ride as Caesar was.
He is currently in Rostov-on-Don, the biggest city in southern Russia, having pulled all his troops out of Ukraine over the previous 36 hours. A video showed him in a seemingly amicable conversation with two local Russian army generals at the headquarters of the Southern Military District in that city.
