As they marched the final few metres to the bastion gates, Ba’ken’s attention strayed to the void shield on the Salamanders’ right. The commissar lord, along with his entourage, had already gone inside the Imperial command centre. Overhead, the skies were darkening and the rain intensified. Day was giving way to night.

‘Your tactical assessment, Brother Ba’ken?’ asked Pyriel, noting his fellow Salamander’s interest in the shield.

‘Constant bombardment – it’s the only way to bring a void shield down.’ He paused, thinking. ‘That, or get close enough to slip through during a momentary break in the field and knock out the generatoria.’

Tsu’gan sniffed derisively.

‘Then let us hope the humans can do just that, and get us to within striking distance, so we can leave this sodden planet.’

Dak’ir bristled at the other sergeant’s contempt, but kept his feelings in check. He suspected it was half-meant as a goad, anyway.

‘Tell me this, then, brothers,’ added Pyriel, the gates of the bastion looming, ‘why are they falling back with their artillery?’

At a low ridge, just below the outskirts of the bastion, Basilisk tanks were retreating. Their long cannons shrank away from the battlefield as the tanks found parking positions within the protective outer boundaries of the bastion.

‘Why indeed?’ Dak’ir asked himself as they passed through the slowly opening gates and entered Mercy Rock.

‘Victory at Aphium will be won with strong backs, courage and the guns of our Immortal Emperor!’

The commissar lord was sermonising as the Salamanders appeared in the great bastion hall.

Dak’ir noticed the remnants of ornamental fountains, columns and mosaics – all reduced to rubble for the Imperial war machine.

The hall was a vast expanse and enabled the Imperial officer to address almost ten thousand men, mustered in varying states of battle-dress. Sergeants, corporals, line troopers, even the wounded and support staff had been summoned to the commissar’s presence as he announced his glorious vision for the coming war.

To his credit, he barely flinched when the Astartes strode into the massive chamber, continuing on with his rallying cry to the men of the Phalanx who showed much greater reverence for the Emperor’s Angels of Death amongst them.

The Fire-born had removed battle-helms as they’d entered, revealing onyx-black skin and red eyes that glowed dully in the half-dark. As well as reverence, several of the Guardsmen betrayed their fear and awe of the Salamanders. Dak’ir noticed Tsu’gan smiling thinly, enjoying intimidating the humans before them.

‘As potent as bolt or blade,’ old Master Zen’de had told them when they were neophytes. Except that Tsu’gan deployed such tactics all too readily; even against allies.

‘Colonel Tench is dead,’ the commissar announced flatly. ‘He lacked the will and the purpose the Emperor demands of us. His legacy of largesse and cowardice is over.’

Like black-clad sentinels, the commissar’s storm troopers eyed the men nearest their master at this last remark, daring them to take umbrage at the defamation of their former colonel.

The commissar’s voice was amplified by a loudhailer and echoed around the courtyard, carrying to every trooper present. A small cadre of Phalanx officers, what was left of the command section, were standing to one side of the commissar, giving off stern and unyielding looks to the rest of their troops.
