Beta-Garmon: The Antechamber That Devoured the Titans

Legio Mortis, Vulpa and Fureans meet the loyalist Solaria, Gryphonicus, Astorum and Ignatum in a concentration that Terra will no longer repeat. According to Lexicanum, Sanguinius led against the capital of the cluster a force of Blood Angels and almost thirty Titan Legions — figures the Heresy will not see in the field again. Few god-machines will remain on the surface of Holy Terra, and John French’s “Mortis” will finish off the survivors with exactly this pair: Legio Mortis rams the Mercury Wall, Legio Ignatum holds it.

Beta-Garmon is the place where the Collegia Titanica ceases to be an instrument of the Great Crusade and becomes the graveyard of the civil war. Knights and the Excertus die in the shadow of Titans’ feet, as the Solar Auxilia did on Isstvan — but here there are thousands of feet. The canon gives no convenient “exact” table of surviving Titans; the atlas does not make things up.

An honest conclusion: after 013.M31 neither side retains a stock of Titans sufficient for a field war of the old crusading kind in Segmentum Solar. That is why the Solar War is spheres and fleet, and the Siege is walls and a daemon — not a second Beta-Garmon around Luna. For a reader of the Legions this is unpleasant: Beta-Garmon is “not about the Astartes”. For a reader of the Siege it is essential: without this scorched Collegia, Dorn could still have met Horus in the field, and not only at the ferrocrete.

Legion VII loses the right to be the “strategic reserve of the crusade”: the reserve has been burned in the antechamber. Legion IX, already wounded at Signus, pays again and reaches the Eternity Gate smaller than it could have been. Legion XVI loses its veterans of Ullanor, whom Chaos later “replenishes” with something else. Legion IV breaks yet another fortress-cluster and arrives at the Palace weary of other people’s triumphs.

There is a widespread mistake about Legion V, and it must be dispelled outright: the White Scars are not here “on the fringe”. Khan brought the Legion to Beta-Garmon — about a month late because of the warp — and immediately set up a raiding war of his own in the theatre. It was he and Sanguinius, the two of them, who recognised that Dorn’s gamble was spent and that it was time to return to Terra. “The Path of Heaven” is not an alternative to this meat grinder but the road that led into it.

On the map, even so, do not place all the loyalists at Beta-Garmon: the Lion, Guilliman and the Wolves are not here as masters of the campaign — once again the geography of delays and divisions. Comparing it with Isstvan V is useful with the opposite sign: there three Legions were killed within days by a cauldron of treachery; here many forces were killed over years by honest (relatively speaking) attrition. Here Horus lies less and pays more. That is why the victory of 013.M31 is joyless even for him: the road is open, the instrument is erased.

Time — from 010 (Nyrcon) to 013.M31 in the Beta-Garmon cluster, remembering that the lower bound of the campaign according to Lexicanum is 006.M31. The routes of the loyalist muster and of the traitor muster at Ullanor. Book — “Titandeath”; alongside it “Slaves to Darkness” for the politics of the traitor muster.

Do not begin the Siege without closing this theatre: otherwise it seems that Horus “simply flew in”. The internal slicing of the campaign in the sources is unsteady — how many “battles” exactly lie within the cluster; the atlas holds Nyrcon and the climax as brackets. The worlds of Ollanz are not a substitute for the cluster but a linked strike: the Scouring of the Ollanz Cluster in 012.M31, where Horus intercepted loyalist reinforcements that were heading for Beta-Garmon and refuelling in the Borman system.

If you are looking for the “greatest battle of the Heresy”, the canon often points here for its Titans, and here, too, contests the Siege for its manpower. There is no need to choose. What matters is to see the kind of war: the last one in which the field can still be lost and one can fall back to the star. After that there is nowhere to fall back to: behind Beta-Garmon lies Sol, behind Sol — the cabin.
