As well all know, after the Horus Heresy Roboute Gulliman demanded that the Legions split themselves into Chapters.
 
 The loyalist Primarchs were split with Dorn heading the "anti-split" camp... A civil war nearly took place and Dorn gave in once his ships were fired upon.
 
 And yet Leman Russ was able to happily disregard this turn of events completely and leave his legion intact? Why on Earth did that happen? If Rowboat's camp fired upon Dorn why would they not attack Russ?
 
 Someone please explain to me why the Wolves got away with what the Fisties couldn't?
