Dan Abnett - Necropolis

What's that? bellowed Feygor, firing over the buttress. Rawne ducked along to him. What?

Feygor pointed down. An armoured machine, three times the size of a main battle tank, was advancing towards the wall's skirt, a huge derrick of armour-plated scaffolding growing out of its top.

Siege engine! For feth's sake! Get on the vox, tell Gaunt!

Feygor nodded.

Rawne scrambled closer to the lip and the las-storm below. Bragg! Bragg!

The big trooper crawled over, hefting his missile launcher.

Kill it!

Bragg nodded and raised the launcher to his shoulder, then banged off three rockets that curled down towards the vast engine on plumes of blue smoke. They hit the superstructure and ignited, but no serious damage was done.

Reload! Again!

The monstrous siege engine reached the foot of the Wall and there was a shrieking sound as the metal tower scraped against the ceramite and stone facings. Gas-fired anchor ropes were shot into the Curtain Wall to hold the engine in place. Hydraulic feet extended beneath the armour skirts of the engine to steady it on the broken ground. With a wail of metal, the derrick tower began to telescope up, extending to match the height of the wall. Segmented armour, badged with the Zoican crest and other, less human insignias that made Rawne sick to see them, unfurled upwards to protect the rising throat of the siege tower.

At the same time, the base unit of the vast machine opened a well-protected hatch in its rear and Zoican troops began to pour into it.

The tower-top rose above the wall's lip, forty metres from Rawne. Hydraulic arms wheezed out and gripped the buttress, steel claws biting into the ceramite. The tower-top was an armoured structure with heavy flamer mounts positioned either side of a hatch opening.

Get down! Get down! Rawne bellowed.

The flamers drenched the top of the Wall with liquid fire, swivelling to rake the defences back and forth. Forty Vervun Primary troopers and nine Ghosts were incinerated as they fled back from the engine.

In addition to the shrieking flamers, automatic grenade launchers on the tower-top whirred and began to lob explosives out like hail. Multiple detonations exploded along the scorched wall.

Rawne fell into cover behind a bulwark with Bragg, Feygor and several other Ghosts. Feygor was firing his lasgun at the tower, but his shots were simply dinking off the armoured superstructure. Vervun troops, some on fire, fled past them.

Bragg!

Got a blockage, replied the giant, fighting with his launcher.

Load him! Rawne ordered Trooper Gyrd.

Gyrd, a grizzled Ghost in his forties, swung in behind Bragg as the big man got the launcher settled on his shoulder. The older Ghost fed fresh rockets into the load-cylinders of the massive weapon.

Clear! bawled Bragg as he sent a missile directly at the tower head. It blew the left-hand flamer mount clean off and ignited a huge fireball of venting prometheum. But the armoured delivery section remained unscathed.

Wait, wait hissed Rawne. The skin on the left-hand side of his face was blackened and scorched by the flamer wash. If he lived till morning, he'd have what the Guard called a flamer-tan.

For what? barked Feygor. Another moment and that hatch'll open. Then the bastards will be all over us!

For half a moment, then. We can't make a dent on this thing, so we wait for that hatch.

The remaining flamer point raked back and forth, its white-hot fires beginning to blister the stone. Then it cut off and drips of fluid fire pooled out of its blackened snout. The grenade throwers stopped whirring.

The storm hatch opened with a shriek. For a scant second, the wall defenders saw the first of the ochre-armoured Zoican troops waiting to deploy out into Vervunhive.

Bragg fired three missiles, one of which went wide. The remaining pair disappeared into the hatchway. The tower-top blew out from within. Secondary explosions rippled down the tower structure and ablaze from inside, it toppled and crumpled with a tearing, metallic wail.

The defenders cheered wildly.

Move back in! Cover the wall! urged Rawne.

Six more siege engines had crawled forward towards the Curtain Wall in the time it had taken Rawne to repel the first.

Relentless fire from missile batteries had taken one apart before it could deploy, just short of the Sondar Gate. Another reached the Curtain Wall intact but positioned itself in front of an Earthshaker heavy battery in the Wall side. The massive, long-range cannons blew it apart point-blank, though the crews were fried by the flaming backwash that rushed into their silos.

A third reached Sondar Gate and deployed successfully, rising and clamping to the gatehouse top and then torching everything and everyone on the emplacement before opening its hatch and disgorging wave after wave of Zoican heavy troopers. The Vervun Primary forces were annihilated by this assault, but Volpone units from the neighbouring ramparts, under the command of Colonel Corday, scissored in to meet the invasion.

Some of the fiercest fighting of the First Storm took place then, with twenty units of Volpone Bluebloods, including a detachment of the elite 10th Brigade under Major Culcis, undertaking a near hand-to-hand battlement fight with thousands of Zoican storm troops. The regular Bluebloods wore the grey and gold body armour of their regiment, with the distinctive low-brimmed bowl helmets. The elite 10th had carapace armour, matt-black hellguns and bright indigo eagle studs pinned into their armaplas collar sections. Culcis, who had won himself a valour medal on Vandamaar, was young for a member of the tenth elite, but his superiors had rightly noticed his command qualities. Despite seventy per cent losses, he held Sondar Gate through nothing more than tactical surety and brute determination.

The top of Sondar Gate and the walls adjacent were thick with corpses. Culcis and his immediate inferior, Sergeant Mantes of the regular Volpone, tried to disable the siege engine with tank mines. Mantes died in the attempt, but the mines blew the support claws off the tower and it collapsed soon after under its own weight. Culcis, who had lost a hand in the detonation of the mines, reformed his forces and slaughtered all the remaining Zoicans who had made the wall-top. For the first of what would be three serious attempts, Sondar Gate resisted the enemy.

The fourth siege engine reached the Wall east of Sondar Gate, midway along the stretch that curved round to Veyveyr. Here Roane Deepers were in position, hard-nosed shock troops in tan fatigues and netted helmets. General Nash was in command in person and he mobilised the wall batteries to target the tower neck as it extended up towards them. The ripples of missiles didn't destroy it, but they damaged some internal mechanism and the tower jammed at half-mast, unable to reach the Wall top and engage. It raked upwards with its flamers and grenades spitefully, and Nash lost more than forty men. But it could not press its assault and remained hunched outside the Curtain Wall, broken and derelict, for the remainder of the war.

The other two siege engines assaulted Hass West Fort.

Gaunt saw then coming, slow and inexorable, and drew up his heavy weapons. He'd seen the system of assault through his scope watching Rawne's position, and he didn't want it duplicated here.

Under his voxed commands, the wall batteries strafed the nearest engine heavily and succeeded in blowing it apart. The upper section of the tower, beginning to telescope, snapped off to the left in a fireball, destroying the base unit as it collapsed.

But despite Gaunt's efforts, the second siege engine reached the western portions of the ramparts and engaged its clamps. The tower hoisted into position.

Gaunt ordered his men back from the surrounding area as the flamers retched and blasted and the grenades rained.
