The Battle of Helsreach

The Shadow of the Second War

At the close of the Second War for Armageddon in 941.M41, Ghazghkull Mag Uruk Thraka — the prophet-warlord of Goff descent who had welded a hundred clans together under a single eye and a single WAAAGH! — was driven from the surface but not killed. Commissar-General Sebastian Yarrick, who had led the human defence and would carry the scars and the rifle of that war for the rest of his unnaturally long life, was certain Ghazghkull would return. Yarrick said so on every Imperial Naval bridge that would listen, on every Inquisitorial panel that bothered to call him, and in every dispatch he filed for the next half-century. Most filed him as a paranoid old man.

Ghazghkull spent the intervening fifty years not raiding and not feasting — those things were beneath him now — but recruiting. He moved across the eastern fringes of Segmentum Solar at the pace of a slow tide, absorbing rival WAAAGH!s rather than fighting them, killing only the Warbosses who refused the larger banner. He moved an entire planet, Urghaz, into the field of an apprentice Mekboy gone mad with ambition and stayed three years learning from what was built there. He commissioned a fleet from the bones of three. By the late 990s of M41, an armada larger than any seen since the Beheading Crusades stood in the night beyond the Adeptus Mechanicus listening posts, watching a single forge-world that sat astride the warp lane linking the Segmentum Solar to the entire eastern half of the Imperium.

In the Imperial Palace, the early auspex returns from Armageddon space were initially read as a sensor ghost. Inquisitor Helmar Tybalt's first dispatch — declassified two decades after the fact, when the records could no longer hurt anyone — reads as a sigh in machine code: that something this large could exist at all argued either for a recording error or for an outcome the Imperium had no plan to survive. The dispatch went unanswered for three Imperial weeks. By the time it was answered, the orks had landed and Yarrick was already on the planet, dressing in armour that no longer quite fit him.

The Third War for Armageddon thus began before the Imperium had finished arguing about whether it was beginning.

The Plan and the Southern Anchor

What followed was the largest single Imperial mobilisation of the late Forty-First Millennium. Two dozen Space Marine chapters — many of whom had no prior contact with each other except in dry Codex annotations — were thrown together under a hastily negotiated command structure. Three dozen Astra Militarum regiments arrived in successive waves, including the Catachan Jungle Fighters, the Mordian Iron Guard, the Death Korps of Krieg, and — controversially — penal legions raised from worlds the Inquisition had not finished pacifying. The Adeptus Mechanicus committed entire Skitarii forge-legions and four battle-titans of Legio Metalica. The Adepta Sororitas sent the entire Order of the Argent Shroud, sealing the rites at the chapel of Saint Bibiana before they boarded. They came knowing what Armageddon would cost. They came anyway.

The plan, drafted in haste by High Marshal Helbrecht of the Black Templars and Lord Commander Eddiard Kuhl of the Cadian Sector Command — two men who could agree on very little but agreed that the line must hold — called for the major hive cities to fix the orks while the relief force broke the orbital encirclement. The hives were Acheron, Tartarus, Infernus, Volcanus, Death Mire, Hades, and Helsreach. Each was assigned a primary defender drawn from the Astartes pool. It was understood, though never written down, that not all of them would be held.

Helsreach was the southernmost and most exposed: a coastal manufactorum city of forty million on the equatorial belt of Armageddon Secundus, named for the bone-grey ash beach on which it had grown. It lay closest to the WAAAGH!'s expected primary landing zone, far from the relief force's projected breakthrough corridor, and its loss would unravel the Imperial defensive line from the south. The defence of Helsreach was given to the Black Templars Crusade. Helbrecht held the orbital fleet personally. He passed the land to his Reclusiarch — Merek Grimaldus, the youngest member of the Chapter's High Council to hold that office in three centuries — with a single signal flare and a single phrase, recorded for the Chapter archive.

Grimaldus did not reply. The reply, when it came, would be the city itself.

Hold the southern anchor. Hold it with the bones of the brotherhood if you must.

— High Marshal Helbrecht, recorded fleet vox, opening of Armageddon orbital action

Grimaldus, Reclusiarch

Merek Grimaldus was not what the Imperium would have chosen if it had been asked. He was a chaplain — a Reclusiarch, the highest rank of his battle-faith — not a strategos. His record before Helsreach was a record of one-line entries: the boarding of the heretic frigate Promise of Adraxis at the close of the Wraith-Wars; the relief of the Cadian shrine at Bramaph; the personal execution of three Sisters Repentia who had — in his judgement — failed to die for their oath. He had never commanded a hive defence. He had never commanded anything larger than a strike force of forty brethren. Helbrecht gave him a hundred and fifty Templar brothers, the wider Crusade's veterans where they could be spared, a half-strength Steel Legion garrison drawn from Armageddon's own world, and a city that did not yet understand what was about to happen to it.

What Grimaldus had — what set him apart from the more obvious choices — was a sermon. He had preached at the Templar conclave on Holy Terra in 991.M41 that the Imperium had forgotten what defensive warfare was. The Codex Astartes assumed mobility. The Imperial Guard assumed reinforcement. Both assumed eventual relief. Grimaldus argued, before an audience that included High Marshal Helbrecht and at least one Inquisitor, that this was a lie. That sometimes the relief did not come. That the only doctrine for those cases was to choose where you would die, to choose it well, and to make every step that the enemy took toward that place cost him more than he could afford to pay.

The sermon had not been received warmly. Helbrecht had not forgotten it.

When the orbital lines began to break and the southern continent's communications went dark city by city, Helbrecht's choice of land commander was understood by some of the older Templar marshals as a cruelty — the kind of test a Chapter Master will give a younger officer to either prove the doctrine or be killed by it. Grimaldus appears to have understood the logic and not minded it. He arrived in Helsreach with the relics of his office — the Skull of Cornak, the Crozius Pertinacious, and the iron-bound bones of his predecessor Reclusiarch Mordred, whose ashes Grimaldus had inherited and whose remains he refused to inter until his own work was finished — and he set up the command altar in the nave of the Temple of the Emperor Ascendant on the second night after planetfall.

He did not, in his first vox to High Marshal Helbrecht, ask for reinforcements. He asked for masonry plans.

The Wave Falls

The first ork landings on Helsreach struck the northern wreck-yards on the eighth day after Helbrecht's fleet engaged in orbit. They came not in pods but in roks — vast asteroid-hulled landers that punched through the upper atmosphere in fountains of plasma and crashed into the manufactorum districts, killing roughly nine hundred thousand civilians on impact alone. The boyz who poured from those roks were the largest Goff and Bad Moon greenskins the Imperium had recorded — many already in mega-armour, many already with names. They were not a vanguard. They were not testing the defences. Ghazghkull had given his lieutenant Warboss Skarlok the southern continent personally, and Skarlok intended to hand his Beast Boss the head of the largest cathedral on Armageddon by week's end.

Grimaldus had eight days. He used them to do three things.

First, he stripped the outer city of every defender it had. The northern ten manufactorum districts were given up before the orks arrived — every Steel Legion squad, every Templar boarding-party fragment, every PDF battalion of any utility, was pulled inward. The civilians of those districts were given the option of withdrawal toward the inner hive or remaining at their stations. Many remained. Some were issued lasguns by Templar Initiates who had been told to count, in the Chapter archive, that they had given lasguns to civilians. The Initiates were not told why this number was being recorded.

Second, he ordered the demolition of every Imperial monument in the city that was not a temple. Plinths, statues, columns, war-memorial spires — all came down, their stone repurposed for the secondary walls. Civilian crews who refused were not pressed. Civilian crews who agreed were paid in writs of survival — promises that the Imperial Guard would carry their names off-planet if Helsreach fell. The writs were dated and signed; many of them survived the war in the hands of the families who eventually received them.

Third, he gathered the city's Ecclesiarchal priesthood — the cardinals, the deacons, the parish ministers — in the Temple of the Emperor Ascendant and told them, with no diplomatic preamble, that they would walk the city's defenders out into the streets every morning of the siege; that any priest who could not do this should resign at that hour; and that he, Grimaldus, would walk with them on the first morning to set the precedent. Two cardinals resigned. The rest did not.

When the orks struck, Helsreach had been remade into a sequence of consecrated killing-grounds. The city's defenders were not in their fortifications. They were on the streets, between the cathedrals, with priests beside them.

Cathedral by Cathedral

The first cathedral to fall was the Sanctuary of Saint Capilene the Mute on the city's third terrace. It fell on the eleventh day of the siege, after holding for nine. The orks who took it pulled down the bell-spire with cables strung from a battlewagon and walked through the rubble at a pace that suggested they did not expect resistance further in. They were corrected, in number, in the next cathedral. The Templar squad that took back the third terrace — five brethren of the third company under Initiate Bayard — left no living ork on the avenue between the two churches. They also left no living brethren. Their bodies were carried back through the lines on bier-litters and their armour was not stripped. Grimaldus would not allow it. The bodies were ranged on the floor of the next cathedral in line, and the priests who had been told they would walk with the defenders walked between them.

By the seventeenth day, three cathedrals had fallen. By the twenty-third, six. The defenders had perfected a counter-rhythm: every advance the orks took into a sanctified building was met, four to eight hours later, by a Templar boarding action that did not seek to hold the ground but only to take it back long enough for the priests to retrieve the relics from the altar. The relics — finger-bones of saints, sealed Texts, the Charge-Chime of Helsreach itself — were carried inward, deeper into the city, into the next cathedral that had been quietly prepared to receive them. The orks held the buildings. The Imperium held the bones.

It was during this phase that Yarrick — who had landed at Acheron and was conducting his own war in the north — sent his only direct communication to Grimaldus of the entire siege. The vox was short. It said: `I know what you are doing. Hold the bones. The bones are what they cannot take.` Grimaldus did not reply. The vox was found in the Chapter archive eighteen years later, transcribed in Yarrick's own hand on parchment, marked simply: `Helsreach. Do not lose this.`

Casualties through this phase were sustained but contained. The Templar force lost roughly thirty brethren in the first twenty days — a rate that, projected forward, would empty the Crusade before the relief force broke through. Grimaldus accepted the rate. He calibrated the catechism around it. He gave every brother who fell a place in the daily reading and ordered that the names be spoken in the order the orks had killed them — neither alphabetical nor by rank, but by sequence in time, so that the Chapter's memory of the siege would be the siege's own memory.

The third week ended with the orks twelve city blocks from the Temple of the Emperor Ascendant.

The Temple of the Emperor Ascendant

The Temple of the Emperor Ascendant was not the largest cathedral in Helsreach. The Cardinal's Basilica, on the upper terrace, was three times its size and twice its age. The Cathedral of the Bleeding Banner, on the harbour, had a more famous reliquary. But the Temple of the Emperor Ascendant sat at the geometric centre of the city, on a low rise above the manufactorum districts, where four major avenues met. From the central nave, a defender could see the orks coming down any of those four avenues for nearly a kilometre before they arrived. The temple was, in plain military terms, a killing-floor with a steeple.

It was also — and this is what Grimaldus understood that the older marshals had not — the spiritual centre of the city. The Hive's foundation rites had been performed in the temple's first incarnation. Three Imperial Governors of Armageddon were buried beneath the nave. The bells of the temple had rung the warning of the Second War for Armageddon, and they had rung the all-clear afterwards. When the people of Helsreach thought of the city, they thought of the Temple of the Emperor Ascendant.

To choose this temple as the final defensive position was therefore not a military decision. It was a theological one. Grimaldus chose it because the people of the city believed in it. He chose it because, when the people of the city fled inward through the falling cathedrals, the temple was where they would think to run. He chose it because, if the temple stood, the city would not have to be told to keep fighting; it would keep fighting on its own.

Grimaldus moved the surviving Templar force to the temple on the thirty-first day of the siege. He told them they would not leave it. He gathered the priests, the civilians who had refused to flee, and the relics of every fallen cathedral inside its walls. He set up his command altar before the central reredos and ordered the doors barred from the inside. The Steel Legion squads who had been fighting beside the Templars in the outer city took up positions in the surrounding plaza, knowing that they were the last line outside the temple itself. They did not ask to be allowed inside. None of them, by the siege's end, would survive to ask.

The Chapter does not hold ground. The Chapter holds faith. Ground may be taken back. Faith, if it falls, does not get back up.

— Reclusiarch Grimaldus, addressing the priesthood of Helsreach on the night before the temple line was drawn

The Final Stand

Warboss Skarlok arrived at the Temple of the Emperor Ascendant on the seventy-eighth day of the siege, leading the largest concentration of orks brought to bear on a single Imperial defensive position since the Beast's invasion three thousand years earlier. He had been told, by Ghazghkull, to take this building. He had also been told that the Beast Boss would be displeased if the building was not standing afterwards — Ghazghkull, in his strange theological logic, wanted the temple intact so he could decide what to do with it. Skarlok was to take it, not break it.

This constraint, more than any tactical brilliance on the Imperial side, is what allowed the temple to hold.

The Steel Legion lines collapsed within four hours. The plaza was taken. The outer walls of the temple were breached by hour six. Grimaldus's brethren fell back through the cloister, through the side chapels, through the transept, and finally to the central nave, where they ranged themselves in a half-circle before the altar and waited. The orks who came through the breaches knew they had been told not to destroy the building. They tried, ork-fashion, to clear it room by room without using the heavy weapons that would have ended it in an afternoon.

The cathedral fighting that followed lasted nine days.

Named officers fell in sequence. Castellan Bayard fell on the second day, defending the south transept. Marshal Ricard fell on the third, taking back the cloister. Brother-Sergeant Priamus — who had been Grimaldus's friend since their shared Initiation a century earlier — fell on the fifth day in the corridor behind the reredos, surrounded by the relics of every cathedral that had already fallen. Priamus, in dying, asked Grimaldus to tell the Chapter that he had not run. Grimaldus said he would.

On the seventh day, Grimaldus himself was struck down — not killed, but injured beyond any further movement by his own power. He continued to direct the defence from where he had been dropped, at the foot of the altar, with the iron-bound bones of his predecessor beside him. He raised the Crozius Pertinacious every time an ork came through the line. The orks who saw him do this began to be afraid. This was new.

On the ninth day, the Imperial counter-attack broke the orbital encirclement and the relief force began its descent. The orks at the temple, sensing the wider WAAAGH! beginning to fragment, withdrew. They had not taken the building.

I carry these because the Chapter does not forget. The Chapter does not forget anything. When the last of us falls, the Chapter will be the bones we leave behind, and the bones will remember.

— Grimaldus, recorded by the gun-servitor of Brother-Sergeant Priamus during the temple fighting

The Reckoning and the Catechism

When the relief force reached the Temple of the Emperor Ascendant on the eighty-eighth day, what they found was this: the cathedral standing, partially burnt; a Steel Legion plaza filled with the bones of the city's last lay defenders, the rubble of their barricades not yet cold; in the nave, three Templar brothers still on their feet, two of them visibly wounded; at the foot of the altar, Reclusiarch Grimaldus, unable to stand but unwilling to be carried, the iron-bound bones of his predecessor beside him on the floor in their wrap. He asked the relief commander what month it was. He had lost track during the cathedral fighting.

The Templar force in Helsreach had been reduced from approximately one hundred and fifty brothers to seven who had walked, eleven who could be carried, and a recorded sixty-eight named brethren confirmed dead. The remainder were missing. Of Grimaldus's named officers, all but two were dead. Of the priesthood that had walked the streets with the defenders on the first morning of the siege, none survived. Of the Steel Legion garrison, fourteen of an original four thousand five hundred. Of the civilians who had remained in the inner hive, perhaps one in eight. Helsreach itself, as a manufactorum city, no longer existed. The hive was largely rubble, the harbour silted with the wrecks of three Imperial cruisers and one ork rok, and the population that would eventually return to rebuild was, in every meaningful sense, a different population than the one that had lived there.

But the temple stood. The line held. The southern anchor had not broken. And Ghazghkull, having spent more of his WAAAGH! at Helsreach than at any other engagement of the Third War, withdrew from the southern continent and never returned to it.

Grimaldus walked off Armageddon. He carried, as he had carried throughout the siege, the bones of Reclusiarch Mordred — and he carried, now, the bones of Brother-Sergeant Priamus, gathered from the corridor behind the reredos, wrapped in a Templar banner Grimaldus had taken from a brother who could no longer carry it. The bones of both were eventually interred at the Eternal Crusader, the Black Templars' fortress-monastery vessel, in a chamber Grimaldus had constructed with his own hands during the void-transit. The chamber is open to any brother of the Chapter who wishes to read the names of those who died at Helsreach. The names are read in the order the orks killed them.

The siege is now Black Templars doctrine made flesh. Every neophyte hears the catechism. Every cathedral the Chapter constructs borrows architectural cues from the Temple of the Emperor Ascendant — the four-avenue sight-line, the low central rise, the gallery for civilian sanctuary above the nave. The Imperium uses the engagement as a teaching case in the Schola Progenium for grinding defensive warfare against numerical superiority that does not exhaust itself. Grimaldus, now an Honoured Reclusiarch and one of the most senior chaplain-officers in the wider Astartes corps, has been heard to say — by those few who have heard him say anything at length — that he is grateful to have been chosen for Helsreach, and that he would not have chosen otherwise.

Ghazghkull, having been bled white at Helsreach and the wider Armageddon defence, retreated to plan a Fourth War. He has not yet launched it. The Imperium suspects he is waiting until the Indomitus Crusade is committed elsewhere. Yarrick, whose warnings half a century before the Third War had been filed as paranoia, is still alive — or was, the last time the Inquisition could confirm. He has been seen, the records say, on a number of frontier worlds that share a single feature: they are all positions an ork WAAAGH! would have to pass through to reach Holy Terra.

The bells of the Temple of the Emperor Ascendant ring every dawn. They have not been silent since the relief force arrived.

Hold this city. Hold this temple. Hold the line. There is no further line to hold.

— Reclusiarch Grimaldus, attributed Helsreach
