The Red Scimitars are a Loyalist Space Marine Chapter of unknown Founding and origin. Almost nothing is known about this Chapter in Imperial records except for the location of their homeworld within the Pandraxx Sub-sector of the Acteron Sector of the Segmentum Ultima.
- The Pandraxx Annihilation (345-800.998.M41) - In 998.M41, Chaos Cultists rose in a massive revolt across the Pandraxx System. Imperial forces within the system were able to successfully contain the revolt, until they were overwhelmed by a Chaos Space Marine battle fleet which launched a surprise attack in support of the rebels. When relief forces including the Red Scimitars finally arrived months later the Chaos fleet had disappeared, leaving the entire Pandraxx System ravaged. Less than 1% of the population were left alive in the aftermath of the Chaos assault.
- The Battle of Trantarion Station (998.M41) - When Chaos Space Marines belonging to the Angels of Pain Renegade Chapter mounted a raid on the Imperial world of Trantarion Station, they were engaged by the Space Marines of the Red Scimitars Chaper's 4th and 5th Battle Companies. The running battle lasted several days until the Renegade Astartes were defeated and forced to retreat from the star system. As a last act of defiance and vindictiveness, the Renegades unleashed a barrage of seismic missiles and virus bombs upon the doomed planet, destroying the colony and rendering the entire planet uninhabitable by humans for centuries.
