From Destinypedia, the Destiny wiki
After the deaths of multiple Red Legion officers, a chunk of the army left the leaderless Legion and tried to carve out their own strongholds throughout the Solar System. The first few accounts were Cabal escapees that The Spider issued bounties for, along with those hiding within the Reef. Others have been noted to have been working with the Spider instead as his associates.
Later some would go onto form the "Unbowed Legion" in the Solstice of Heroes event who submitted to no one. These deserters managed to build a stronghold by the European Aerial Zone, but were unfortunately cut down by the Guardians seeking to improve themselves. It has been observed that many deserters seem to be former Blood Guard as the "Unbowed Legion" had several majors of them. This fact alone shows insight to the crippling morale of the Red Legion Cabal structure as with Ghaul and the High Command gone, the Blood Guard have lost their primary purpose.
During Penumbra, Calus would task Guardians in ending a lead deserter in The Conflux on Nessus in order to obtain Imperials from him and his group of Deserters. Some deserters were also observed in The Arms Dealer strike.
With the recent events of Season of the Worthy, it is known more Cabal have deserted, but their specific names and numbers remains unknown.
