Appears you were right. @clashrepor The Telegraph, citing British Intelligence sources: Russian security services have threatened to harm the families of Wagner leaders if Wagner's rebellion was not stopped.
How could he not anticipate that as a likely response to an insurrection? Seems like moving your family to a safe location would be the first thing you'd do before starting a coup.
About as well thought out as that time Russia invaded Ukraine with barely enough food and fuel to cross the border...
