Uriel's drop-pod hammered down in a blazing flare of rockets and pulverised metal decking. Explosive bolts blew out the heat-shielded doors, and the locking harnesses securing the Space Marines within snapped upright. What had been a hermetically sealed environment for travel through the cold of space and the heat of re-entry was now open to the elements and the reek of propellant and scorched metal filled the air.
'Go! Everyone out!' shouted Uriel, and the warriors who had endured the thunderous ride from the embarkation deck of the Vae Victus with him leapt instantly to obey. Uriel led them from the drop-pod, taking in the ebb and flow of the battle in a moment.
Learchus had done his work well.
The Praxedes detention camp was in uproar, with desperate Fire Warriors in combat with hordes of equally desperate prisoners. The fighting was ferocious, but it was clear that the tau had the upper hand. Though considerably outnumbered by their captives, the Fire Warriors were highly-trained and had no give in them.
Numbers and courage could carry any assault far, but against disciplined soldiers armed with powerful weapons, it was never going to be enough, and the Lavrentian prisoners were being slaughtered. Uriel saw Learchus and two scouts firing on a battlesuit squad from the cover of a barrack building. While the weight of fire kept Learchus pinned in place, two other battlesuits were moving to encircle him.
Chaplain Clausel's voice sounded in his helmet. 'Our arrival is most timely.'
'So it would appear,' said Uriel, quickly identifying the key points of resistance. 'Secure the gate. I will link with Learchus.'
'Understood.'
The tau forces were reacting swiftly to the arrival of the Astartes, turning their guns on the new threat in their midst. Flurries of blue energy beams slashed towards the Space Marines, but they were answered by a weight of fire greater than isolated bands of infantry could hope to muster.
Landing seconds before the main assault, drop-pods equipped with automated heavy weapon systems instead of troops unleashed furious barrages of missiles upon the tau. Following preset logic parameters, they engaged targets with merciless precision, and explosions ripped through the greatest concentrations of Fire Warriors.
The tau reeled from the shock of the sudden violence of the assault, but Uriel knew from past experience that they would recover quickly. To win this fight, the Ultramarines would need to keep the tau on the back foot, never allowing them to regain the initiative.
Two further drop-pods slammed down, buckling the metal of the landing jib's deck and scorching it black with the fire of their retros. Sequential bangs sounded like a string of firecrackers, and the wider doors of these drop-pods fell open to reveal the ancient and revered Dreadnoughts of the 4th Company.
Brother Speritas stepped into the battle with his assault cannon roaring, and a string of missiles leaping from the armoured rack mounted at his shoulder. Zethus followed his brother Dreadnought's example, opening fire on the tau the instant his fiery chariot's doors were opened. Twin beams of incandescent laser energy blew the turret from a Hammerhead as it turned to face the Dreadnoughts, and a tongue of blazing promethium jetted from beneath his monstrous crackling fist.
The tau fell back from the two Dreadnoughts in disarray, leaving dozens afire behind them. Powerful though the Fire Warriors' guns were, they could not hope to defeat the armour of such mighty war engines.
Clausel's squads arced on fiery jump packs towards the entrance of the prison complex, gunning down those Fire Warriors that had disembarked from their Devilfish transports. Hammerhead battle tanks floated gracefully through the fires of battle, their enormous guns tracking around to unleash their fury upon the Space Marines.
Chattering cannons and blisteringly bright spears of high energy tore into the Space Marines alongside Clausel, and Uriel saw that not all would be getting to their feet. He grieved for the fallen, but the assault had always carried the risk that many of the 4th Company would be returning to Macragge as honoured dead.
A drop-pod exploded behind Uriel, the Ultramarines it had carried swatted to the deck by the blast. Most climbed swiftly to their feet, but three remained on the ground. Barely seconds had passed since the thunderous arrival of the Ultramarines, yet the tau had already realigned their defences to meet the threat.
A warrior in brilliant blue armour emblazoned with a glittering golden eagle, and who wore a white-winged helmet, stood next to Uriel. His cloak billowed in the thermals of the drop-pods' descent, and he carried a long pole of black adamantium topped with a crimson crosspiece.
Ancient Peleus unfurled the banner of the 4th Company, and the power of its magnificence was akin to the sight of a hundred other Space Marines. The gold leaf and silver threading of the clenched gauntlet glittered in the sun, and its sacred fabric was a beacon to every warrior of courage and honour who beheld it.
'The banner of the 4th flies above us!' shouted Uriel. 'Let no warrior falter in his duty to the Chapter!'
His warriors answered with a cheer of pride and love, their devotion and faith in the power of the banner pushing them to new heights of courage. To fight beneath the company standard was an honour, and every warrior knew that the heroes of the past were watching them, standing in judgement of their courage. The Lavrentian prisoners had been on the verge of breaking when the tide had turned against them, but, with the arrival of the Ultramarines, they surged from their bolt-holes to once again attack the tau. Though the standard of the 4th was not their own, it represented centuries of courage that spoke to the heart of every warrior who beheld it.
Uriel led squad Ventris and the standard towards the barrack building where Learchus and his warriors fought. He fired as he ran, for there was no shortage of targets. Fire Warriors dropped with every volley, as shots flashed past Uriel's head and skidded from the deck around him. Running battles between prisoners and Fire Warriors filled the compound, and Uriel was forced to weave a path through the struggling combatants.
Hot air blasted downwards, and Uriel looked up to see a tau aircraft roar overhead. Bulky and oblong, he recognised it as an Orca, and he knew exactly why its pilot dared risk flying over such a hostile environment.
The craft was soon lost to sight, and Uriel pounded onwards through the warzone of the camp. Learchus looked up as Squad Ventris drew close, and Uriel saw the swell of pride in his sergeant as he caught sight of the banner they carried.
'Squad Ventris!' shouted Uriel. 'Combat squads. Hold and engage left!'
His warriors smoothly split into two units, one bracing and opening fire on the Battlesuits pinning Learchus and the scouts in place. Rippling volleys of bolter-fire hammered the battlesuits, a pumping barrage of shells that detonated within the armoured chest cavity of the first enemy warrior and sent the other into cover.
The second combat squad followed Uriel to join Learchus and his ragtag scouts, but there was no time for greetings, for the two flanking battlesuits roared over the roof of the barrack building. They landed in a flurry of exhaust gasses and gunfire. One of the scouts screamed and went down, his kneecap a pulped mess. Another, a sergeant, dropped as a shell clipped his shoulder and spun him around.
A white-hot lance of plasma bored through the chest of an Ultramarine, and the warrior fell, dead before he hit the ground. Uriel and Learchus charged the battlesuits as the second unleashed a seething torrent of fire from its weapons. Uriel felt the heat of the fire wash over his armour, and red warning icons flashed up on his visor. Coolant gasses vented from his armour's backpack as it fought to counteract the heat, and Uriel heard cries of pain behind him as the lightly armoured scouts scrambled back from the killing flames.
