Overall I find it unlikely that the Traitors are more numerous after 10,000 of attrition and losing a war. It’s possible that as few as 100,000 or less survived. Even if the other Traitor Legions fared better, it still seems unlikely they got by with more than half their starting numbers intact. If we take the sometimes quoted 85,000 pre-Heresy number that would be only around 1% survived. This would mean only a 10th of the Legion survived the HH if we take 10,000 as their Pre-Heresy number. It’s mentioned in A Thousand Sons that only 1,000 of the Thousand Sons survived the attack on Prospero (Not the first time they’ve been reduced to that size). Now we have no idea at all how many CSMs survived the Heresy, or how many have died or fallen since then. This would suggest that Isstvan III alone cost the Traitor Legions 10% of their number.Įven if we assume that no other members of the Nine Traitor Legions remained loyal, which we know is untrue, that puts CSM forces post Isstvan III at somewhere around 800,00-1,000,000. Betrayal, for instance, states that the loyal members of the Sons of Horus, World Eaters, Emperor’s Children, and Death Guard killed at Isstvan III numbered about 100,000, with the Sons of Horus losing some 60,000 total, loyalist and traitor in the battle. This number includes a large number of Marines who remained loyal and either defected or were purged.

Looking at various sources, we can see that the Nine Traitor Legions seem to have had between 925,000 and 1,190,000 Marines (with the Thousand Sons and Alpha Legion having a vast range of possible sizes) at the start of the Heresy. Though a Legion was once stated to contain 100,000 Space Marines, that number seems to be more an average or ideal than a real number. While exact numbers are impossible to come by we do have some vague idea of how many Marines were in the Original Traitor Legions. How Many Chaos Marines Are There Right Now? However, the intervention of Cawl and the resurrection of Guilliman along side the introduction of the new Primaris Marines means that Chaos should now be hopelessly outnumbered. The Fall of Cadia and the opening of the Great Rift destroyed that equilibrium, and temporarily seemed to put the Imperium on the back foot. Key among them are the forces of Chaos, lead by traitor Marines.

There are HOW many Primaris Marines out there? Let’s do a different kind of mathhammer.įor decades GW kept 40K in a delicate balance, with the Imperium holding (barely) its borders against a host of threats.
