The Purging of Kadillus

by Gav Thorpe

  The surviving biker veered wildly to the left and right, the pennant whipping back and forth, billowing dust almost filling the gorge. It was impossible for the ork to aim its weapons at such speed; torrents of heavy bullets screeched overhead and rattled around the upper storeys of the power plant. It was ludicrous behaviour and Boreas concluded that the alien had been filled by some kind of strange battle-mania.

  The thudding of the heavy bolters joined the crack of lascannons and shriek of autocannons as the biker roared closer and closer. A bolt exploded against the magazine of one of the bike’s cannons, igniting the shells within. Trailing fire and smoke, the warbike careened across the gorge, bouncing over rocks and cracks, until it smashed into the wall of the gorge. Fuel and oil spilled down the slope back in the direction of the orks. Ammunition continued to pop and a few seconds after impact a shower of sparks set the slick aflame, a crackling inferno engulfing the right-hand side of the gorge.

  Switching his helm to terrorsight to peer through the fumes and dust filling the approach to the mine head, Boreas could see another half-tracked vehicle closing swiftly. It was a little larger than the warbikes and pulled a long trailer connected by a profusion of tubes and pipes. A diminutive gretchin clung on to the back of the trailer, holding on to a wheel-lock for dear life. Over the head of the driver extended a funnel-like spout dripping with burning fuel.

  It was only when Boreas noticed that the Piscinans were not shooting that the Chaplain realised the crude cunning of the ork plan. The greenskins’ commander had sent the bikes forwards knowing they would be destroyed, and in the close confines of the gorge, the dust and smoke were blocking the aim of the troopers defending the geothermal station. It was a screen to allow the orks to get closer.

  ‘Mortars!’ Boreas bellowed. ‘Fill that gorge with bombs!’

  The troopers responded as quickly as they could but the flamethrower half-track was already roaring out of the smog, the driver gunning his vehicle directly at the closest emplacement. Shocked Piscinans shouted warnings to each other and a few autocannon rounds zipped down the gorge without finding their mark.

  The whine of descending mortar bombs joined the roar of the half-track’s engine and the cries of the defence force officers. A ripple of explosions tore from left to right across the gorge, metres behind the approaching vehicle, throwing up another curtain of dust and smoke.

  ‘Sergeant Zaltys!’ Boreas turned to face the Assault squad. ‘Intercept that vehicle before it reaches the defensive line!’

  ‘Affirm, Brother-Chaplain.’ The sergeant was already leading his squad forwards with long leaps as he replied.

  Covering twenty metres with each jump, the Assault squad sped down the ravine, their pistols hurling bolts and blasts of plasma at the war-track. The vehicle’s gunner heaved around the nozzle of the flamethrower and fired. A jet of bright orange arced across the gorge, engulfing Zaltys’s squad. One of the Assault Marines was caught full by the inferno and tumbled mid-jump, crashing into the rock amidst a plume of flames and flying shards of armour. The others plunged out of the crackling wave of flame, fire licking from their blackened armour.

  The gunner fired again and swung the flamethrower around as the vehicle’s driver swerved away from the charging Space Marines. Burning fuel erupted across the boulders and rocky ground but fell short. Zaltys and the others burst through the sheet of flame and fell upon the vehicle with fierce war cries.

  One Assault Marine landed on the front of the track housing, a booted foot smashing the driver from his saddle. The ork tumbled beneath the whirring links, the towed fuel trailer bouncing over its mangled corpse.

  The mad swaying of the trailer caused Zaltys to mistime his leap; the sergeant crashed shoulder-first into the side of the trailer, dislodging the gretchin atop the cylindrical tank of fuel. Metal panels burst their rivets and thick, oily sludge seeped from the ruptured tank, spilling over the sergeant and another of the Assault Marines.

  Even without a driver, the ork vehicle roared onwards up the gorge, the Assault Marines leaping after it. One of the squad landed squarely on the back of the fuel trailer. Boreas saw the Space Marine slap a melta-bomb onto the side of the leaking tank and heard the warning shout across the comm.

  Less than a dozen metres from the foremost emplacement, the squad peeled away from the doomed vehicle, launching themselves high into the air with their jump packs as the melta-bomb detonated. The fuel tank exploded with a blast that sent a hot wind rushing up the valley, throwing several of the closest Piscinans from their feet. The remnants of the half-track were hurled in a burning arc across a line of dirt-filled crates, and crashed against the rough wall with another detonation.

  There were a few cries of pain from wounded troopers. Sergeants and officers bellowed to their men to keep the line while two medics dashed forwards to see what could be done for those caught in the explosion. Boreas spied the gretchin who had been flung clear of the trailer crawling behind a rock. He was about to warn Zaltys but the sergeant had already seen the creeping greenskin. The sergeant’s hand flamer bathed the creature’s hiding place with white-hot fire.

  ‘Live by fire, die by fire,’ Zaltys grunted over the comm, no doubt with some satisfaction. The sergeant crossed the gorge to his fallen battle-brother and shook his head. ‘Brother Lemaseus is dead. Remember him for his sacrifice.’

  ‘His deeds will live for eternity,’ Boreas replied.

  The Assault Marines hauled up the smoking body of their fallen comrade and carried it back towards the mine head. Behind them a dark mass could be seen through the thinning smoke as the orks raced up the gorge. Boreas could hear their guttural war shouts, the jangle of wargear and the clump of boots on rock.

  ‘Stand ready to engage the enemy,’ the Chaplain commanded the troopers around him.

  The orks rushed from the smog as a wall of green flesh, clothed in black and yellow. Boreas saw glaring red eyes and snarling fangs, repeated hundreds of times as the baying ork mob thundered between the rocky walls of the gorge. They howled and roared their challenges as they pounded up the slope.

  Boreas heard answering shouts, of dismay rather than anger. Amidst the din of the orks’ charge he detected the scrape of boots and the thud of dropped weapons. Turning to his right, he saw at least two dozen of the Piscinans abandoning their posts, ignoring the shouts of their sergeants.

  The fleeing troopers streamed back into the geothermal station as quickly as they could run, their panicked shouts urging their fellow Piscinans to come with them.

  ‘Hold the line!’ roared Boreas, swinging around to confront the closest defence troopers. One or two that had been edging away from the barricade slunk back into position and lifted up their lasrifles. ‘Open fire, damn you!’

  Utterly livid at the Piscinans’ retreat, Boreas wanted to snatch up the cowards and dash open their skulls on the rock. He took several steps towards the fleeing men, blazing crozius in hand, but stopped as the snap of las-fire and the crack of ork guns reminded the Chaplain that he had more immediate concerns.

  ‘Traitorium eternis. May your souls rot in the darkness of the abyss for your treachery,’ Boreas snarled at the swiftly disappearing backs of the departing troopers.

  He returned to his position to find the orks barely a hundred metres away. As he had feared, some of them had reached the outbuildings unscathed and were unleashing heavy if inaccurate covering fire for those greenskins still sprinting towards the troopers’ line. Bullets and las-bolts criss-crossed the narrowing gap between defenders and attackers.

  The mortars opened up again, ripping holes into the oncoming mass of green flesh. Swathes of orks were bloodily hurled from their feet as the autocannons added their roar to the defence.

  Boreas gauged the state of the battle with one sweeping glance. The fire from around him was sporadic as the orks in the ruined administration building poured bullets into the barricades. Despite that, the orks were slowing as more and more of their numbers fell to the wall of
las-fire and shells. To the right the orks were approaching more swiftly, heading for the gaps left by the troopers who had fled. The left was holding firm, pinning the orks back behind a line of rocks that jutted out from the wall of the gorge.

  ‘Boreas to Zaltys, cross to the right flank and cover the holes left by those cowards.’

  ‘Affirm, Brother-Chaplain.’

  As the Assault Marines powered from one end of the line to the other, Boreas pulled out his pistol. The orks had slowed in their advance and stopped every few metres to snap off shots at the geothermal station’s defenders. Had he been commanding a force of Astartes, Boreas would have ordered the counter-charge at this point, to drive the orks back down into the gorge. Such a tactic was not an option; Boreas knew it was a hope that the Piscinans would hold their line and there was no chance they would want to get any closer to their enemies.

  ‘Fire discipline!’ Boreas bellowed at the officers within earshot, noting the sporadic and woefully inaccurate bursts of las-fire from the troopers as they hurried their shots. ‘Mark your targets and concentrate your fire.’

  A small measure of order rippled along the line from the Chaplain and the rush of fire slackened for a few seconds and then intensified into proper volleys. The ork dead littered the ground and those that survived were reluctant to leave the cover of the rocks and ruined buildings. There were few enemies within range of Boreas’s bolt pistol. Those that were foolish enough to show themselves were quickly picked off by the Chaplain, who fired short bursts of two and three shots with unerring accuracy.

  Slowly the orks lost interest in the firefight and slunk back down the slope, occasionally turning to unleash a hail of bullets or hurl insults.

  The ferocity of the battle waned. As the odd bullet whined up the gorge from the administration building, Boreas walked the line to inspect the state of his force. About a tenth of the troopers had fled from the initial onslaught and a few more had slipped away in the confusion of battle. Casualties were surprisingly light, no more than ten troopers had been killed – along with Brother Lemaseus – and another fifteen were too badly wounded to fight on. About twice that number had suffered lesser injuries and were shepherded back to their posts by their officers, bloodied and bandaged.

  All in all Boreas was pleased with the Piscinans that had held their nerve and stayed on the line. Of those that had deserted, there was no sign. They had fled along the narrow channels and gulleys that criss-crossed the slope of the mountain and were no doubt already heading back to Kadillus Harbour. There was nothing Boreas could do about them now, but he would have words with the Piscinan commanders later to ensure those that had abandoned their posts would be found and chastised.

  There was a brief flurry of more intensive fire from the orks in the administration building, under the cover of which two dozen or more greenskins broke from their hiding places and occupied a low shack that had once been a workshop. The ork shooting slackened again and the two sides settled down to occasional sniping at one another as targets presented themselves. Scornful of the orks’ accuracy, Boreas strode from emplacement to emplacement, reminding the officers of their duty and reassuring the troopers that the worst had passed.

  Reaching the right end of the line, Boreas joined Zaltys. The sergeant was changing the fuel canister on his hand flamer.

  ‘The enemy will come again, brother,’ said the sergeant. ‘Orks won’t have come all this way just to give up after the first charge.’

  ‘Our defiance has blunted their blood-lust,’ replied the Chaplain. ‘They’ll be more cautious next time. They’ll use the administration building to gather their numbers and then come at us through those boulders on the left.’

  Zaltys surveyed the lay of the land and nodded.

  ‘That seems likely, Brother-Chaplain. We can hold this flank, and you can concentrate the Piscinans to the centre and left.’

  Boreas considered this, eyes scanning the battlefield for likely routes of attack, angles of fire and blind spots.

  ‘Very well, brother-sergeant,’ he said. ‘Next time the orks fall back, follow up with an attack to the administration building. I will attempt to lead a second attack along the left and come at the orks from the other side.’

  The Chaplain walked back to the central emplacements, calling for the Piscinan officers to attend to him. He repositioned the heavy weapons squads to cover the administration complex and moved the bulk of the troopers further left to guard against enemies moving through the rocks and bushes that lined the eastern side of the gorge. Further down the slope the orks were also rearranging their forces, flashes of green and yellow moving between the scattered boulders and tumbled walls.

  Satisfied that he was prepared for the next assault, Boreas took up his place at the centre of the reformed line and signalled Master Belial on the long-range comm.

  ‘Chaplain Boreas to Master Belial. Have engaged enemy at Barrak Gorge station. Report to be made.’

  There was no response for a minute. When Belial replied, his tone was clipped and breathless.

  ‘This is Belial. Make your report, brother.’

  ‘The orks have moved to Barrak Gorge during the night and attacked shortly after daybreak, brother-captain.’ Boreas paced back and forth a few steps as he assessed the enemy strength. ‘We have engaged a significant portion of the ork army. Several hundred infantry at a minimum. Several light vehicles destroyed. Risk to the geothermal station is negligible at present, our position is secure.’

  Again there was a lengthy pause.

  ‘It is imperative, absolutely vital, that the orks do not succeed in capturing the power station, brother. Brother Naaman succeeded in breaching the ork lines and we have located the means by which they are reaching the surface. The orks are using Piscina’s power grid to power some form of high-energy teleporter to move their troops from an as-yet-unknown location. I have just returned from an attack at the East Barrens plant to disable their power link.

  ‘Your operation to sever the link between Kadillus Harbour and the Barrens has also curtailed their reinforcements and I expect it is that which has triggered this attack on Barrak Gorge. Any advantage gained from these actions will be lost if the enemy are able to take another power station.’

  ‘I understand, brother-captain,’ said Boreas, staring at the ork army with renewed interest. ‘Barrak Gorge will not fall to the enemy.’

  ‘It must not.’ Belial sharply emphasised every word. ‘I expect the orks to repair the damage done at East Barrens, but that alone will not be enough for them to resume their widespread reinforcement. If we are to contain the ork threat until the rest of the Chapter arrives we must cut off the ork forces at their source. They cannot gain access to another power plant.’

  ‘Understood, brother-captain. The Dark Angels will not allow this world to fall to the foul xenos.’

  ‘Their taint will be cleansed from Piscina. The orks will learn to fear the Sons of Caliban.’

  The next ork attack came just before noon.

  The assault was heralded by a hail of heavy weapons fire from the administration building a few seconds before a tide of green-skinned warriors poured from the doors and broken windows and rushed to the eastern side of the gorge.

  ‘Conserve ammunition and wait for targets,’ Boreas growled to his soldiers. The orks would be desperate to claim the power station and Belial had given no word of when Boreas’s force could expect relief.

  The orks made use of what cover there was amongst the rocks and scrub. Rather than charge headlong into the fire of the Piscinans, the greenskins worked their way forwards with more care. For all their attempted stealth, the orks were too numerous for them to all find cover and a trail of blood and bodies marked their progress up the gorge as las-fire zipped through the bushes and heavy bolter rounds detonated across the boulders.

  Boreas ejected the magazine from his bolt pistol and slipped his hand into a pouch at his belt. He brought out a fresh clip, loaded with special seeker bolts
that Techmarine Hephaestus had presented to the Chaplain after the defence of the basilica. Each handcrafted round contained a miniature cogitator capable of steering the bolt towards the heat signature of a target.

  ‘Let the hidden hand guide thee to the doom of my foes,’ Boreas whispered to the tiny spirits of each bolt as he slotted the fresh magazine in place.

  He switched the tactical display of his helm to thermal view and watched for a few seconds as the orks crept along the gorge, their bodies a white glow amongst the warm yellow of the sun reflecting from stone. With a light touch against the trigger of his raised pistol, Boreas activated the weapon’s targeter and zoomed in on his foes.

  The Chaplain fired a burst of three rounds and watched the fiery trails of the bolts as they flashed through the air. Two of the bolts zeroed in on an ork crouched behind the twisted trunk of a tree, exploding inside the creature’s back and leg. The third turned sharply, rose a few metres and dived out of sight behind a rock, detonating with a shower of blood that showed up as a spray of warm droplets.

  Boreas fired twice more as the orks broke from cover with a storm of pistol fire. The blossoms of the bolt detonations were lost in the hail of las-blasts and muzzle flares that engulfed the surging orks. Boreas flicked back to normal-spectrum view and took in the change of battle at a glance.

  ‘Mortars on the administration building,’ Boreas ordered as a fresh salvo of weapons fire erupted from the complex. ‘Autocannon teams, cover the centre. Left flank, prepare for close combat.’

  He leapt over the rough barricade and pounded to the east to stave off the ork assault. Raging and shouting, the orks poured into the two front emplacements, hacking with their heavy blades and firing madly with their pistols. The troopers stabbed and parried with bayonets and swung the butts of their lasrifles at the greenskins while officers cut and thrust with chainswords and urged their men to hold their ground.

  ‘With me!’ Boreas bellowed to a squad of Piscinans in the next emplacement.
