The revolt itself is very interesting. Odviously they knew Russia was already under heat from the invasion and that would likely help thier cause. But why stop? Were they waiting for other to join who didn't? Did they think they were going to face more resistance earlier and panicked because they got close to Moscow and suspected a trap? Was there some other motivation and the rebellion was a distraction? Whatever the reason it definitely shows that Putin is losing control and that people who used to be his allies can turn against him.
