Fists Exemplar and skitarii struck at each other in the same instant. The close quarters worked in favour of the Space Marines — their armour was stronger than that of the skitarii. Their mass-reactive bolt-shells shattered breastplates and helmets, blowing up the circuitry and flesh within, and the first ranks of the vanguard went down. Radium carbine bullets hammered against Thane’s armour, but his plate held against the poisonous rounds. His auto-senses warned of a massive increase in airborne radiation; if he had not been wearing his helm, his skin would already have begun to cook.
The Fists Exemplar had the momentum of the first seconds, but the Mechanicus had the overwhelming numbers. The temptation was to drive forwards while they could, but Thane knew better. The Space Marines could not depend on their power armour to see them through the enemy cohort before the heavy guns came to bear. The wrong push now would be disastrous.
Or more disastrous. He pushed the thought away, focusing on the need to survive the next few seconds, and to fight for the completion of the mission. He could not afford to consider the wider consequences of what was unfolding.
‘Fall back,’ he ordered the company. ‘Tanks, take the lead. Punch our way through.’ He swept his bolter back and forth as he started to walk backwards. The Fists Exemplar’s hail shattered Mechanicus warriors. Clouds of metal shrapnel erupted. The tanks drew level with the Space Marines. Their cannons roared simultaneously with the shriek of the enemy’s energy blasts. The Predator
‘On me,’ he called to his brothers. ‘Flank them.’
The tank battle became a firestorm of shells and energy blasts. The explosions were continuous, filling the street. Behemoths of war hurled destruction at each other from ranges no greater than a few dozen metres. The Fists Exemplar moved through a storm of flame, smoke, convulsing energy and whirling shrapnel. The foot soldiers of both forces made way for the tanks, and the vehicles picked up speed. Even at such close range, some shots went wide, devastating the manufactoria on both sides of the avenue. Thane led his company towards a structure that was more avalanche than shelter.
‘Thamarius,’ Thane voxed to the sergeant leading the drop pod landing. ‘What is your situation?’ He called twice more before Thamarius answered, barely audible over the raging interference.
‘The Gate is holding strong, Chapter Master. We’re trying to break through with melta bombs, but it will take time. Our position is vulnerable.’
‘Hold fast, brother-sergeant. We will approach from the eastern flank.’
‘We may need more desperate means to defeat this barrier.’
‘Understood. But we are not there yet.’
If Thamarius answered, his words were lost in the static.
A Kastelan robot loomed out of the smoke. It fired its incendine combustor and a flood of ignited promethium washed over Thane’s company. Raalega took the brunt, the high-powered stream burning through the seams of his armour. It filled his helmet. Flesh and metal turned molten. As he fell, he hurled a krak grenade at the robot, slagging the behemoth’s left foot. The robot staggered, the sudden swing of its gait almost crushing the datasmith at its side. The priest died by bolter fire a moment later but the robot still advanced. Deprived of the guidance of its datasmith, it was governed by the last instructions programmed into it. It would walk and burn all before it until it was destroyed or ran out of fuel.
Bolter fire pummelled the robot. The impacts made it jerk as it walked, but its attack was untroubled. Thane ran through the flame, his heat and rad sensors shrieking red. He stepped around the robot’s heavy tread, wiping burning promethium to clear his vision, and trained his bolter on the barrel of the combustor. The gun burst. Its fuel ignited at once, shot skywards, and blew up the robot’s power pack. Thane jumped back, away from the worst of the incinerating flood. The robot burned in its own life force, stopped walking and slumped forwards, arms hanging limply. Immobilised, it became a metal silhouette in a lake of fire.
