The end of the Rynn's World novel had a bunch of chapters coming to their aid after they (oppsie!) blew up their own Fortress-Monastary. But I can't remember who was among the chapters in the relief fleet.

"The Crimson Fists have always had close ties with the Imperium and the Inquisition. They have contributed many warriors to the kill-teams of the Ordo Xenos, being renowned Ork fighters. They have also, at the order of Terra and the Inquisition, destroyed two chapters of brother Space Marines; the insane Sons of Gideon and the mind-wiped Marines Vigilant. This has earned them a reputation as lap dogs of the Inquisition among certain chapters."

Which space marine chapters might raise an eyebrow at Crimson Fists, it doesn't say. Maybe some of the more independent minded ones like Space Wolves or Salamanders.

By way of answer, and not for the first time, Kantor’s mind landed unbidden on memories of the Marines Vigilant and of the terrible destruction the Crimson Fists had brought down upon them.

[SERVICE TO THE HIGH LORDS OF TERRA]
Like other Imperial Fists descendants, the Crimson Fists have always been noted for their zealous devotion to the Emperor, even more so than other Space Marine Chapters. On at least two occasions this has led to the Crimson Fists being called upon by the High Lords of Terra to exterminate a fellow Space Marine Chapter. The first of these was the Sons of Gideon, who were deemed Excommunicate after a routine Inquisitorial inspection had found the Chapter's geneseed had been corrupted to such a degree that chemical imbalances in the Space Marines' brains had driven them insane. The Crimson Fists destroyed their homeworld of Gideon IV and they proceeded to hunt down the remnants of the Third Company which had escaped the attack and was butchering it's way through the four billion inhabitants of the Colar star system The second Chapter to have suffered the wrath of the Crimson Fists were the Marines Vigilant. The Chapter had fallen under the mind-control of a rare warp entity which had eradicated all martial instinct of the Space Marines, rendering them useless as a military force. The unfortunate Marines Vigilant put up no resistance at all as the Crimson Fists used orbital mass drivers to turn the renegade Chapter's verdant home planet into lifeless desert. The Crimson Fists' willingness to turn on their brother marines has earnt them something of a reputation as the Adeptus Terra's lapdogs amongst the more unorthodox Space Marine Chapters, such as the Space Wolves, White Scars and Exorcists.

There are even rumours which implicate the Officio Assassinorum in the downfall of certain Space Marine Chapters - the mysterious loss of the Fire Hawks' fleet in the warp, the unexplained destruction of the Crimson Fists' Chapter fortress on Rynn's World, the disastrous ambush of the Angels of Retribution at Alantor X and several other less well-known incidents have all been laid at the assassins' door.
