Honsou doubted that such a thorough siege would be required to take Tor Christo. The garrison would clearly be able to see the progress the attackers were making and would, in all likelihood, abandon the fortress and pull their men back to the main citadel.
Taking Tor Christo was a necessary precursor to any assault on the citadel, but it was sure to be thankless, bloody work and there would be little glory to be had in such a venture.
This current mission was a prime example of the gritty necessities of a siege. From a distance it was all too easy to rely only on what you could see, trusting to distant observations to prepare a plan of attack on a fortress. Honsou had seen dozens of attacks on fortifications founder due to lack of proper reconnaissance when attackers had run into previously unseen traps or redoubts that rendered their plans obsolete.
Honsou kept one eye on the watchtower that commanded the plateau and one on the ground before him, careful to avoid any fragments of shell casings or discarded weapons and battle gear. Sound carried further at night and the last thing he needed was to be caught out in the open with no immediate support in the vicinity. He and forty warriors from his company crept through the killing zone that had seen thousands of men die that very day, and by stealth, managed to get closer than any of the prisoners had by direct assault.
Carefully, he stepped around a mine his auto-senses detected and dropped a marker for the following troops to avoid. The minefield they traversed presented no significant threat to the Iron Warriors, but it would slow the digging if the prisoners and slaves were afraid of unexploded munitions every step of the way. The crack of metal sounded and Honsou cursed silently as he saw the ponderous form of Brakar Polonas, one of Forrix's senior engineers, step around the mine, marking its position on a light-proofed data-slate. The venerable warrior walked with an awkward, limping gait, his left leg a bionic replacement. It seemed this augmentation also made him incapable of moving quietly. It was a calculated insult by Forrix to send Polonas, letting Honsou know that his information was only trustworthy if accompanied by verification. It was just another entry in a catalogue of carefully measured insults to his prowess. He just hoped Forrix's clumsy insult didn't get them all killed.
He pushed the interloper from his mind as they continued forward, making good time despite their caution and Polonas's lack of stealth.
Honsou was now less than two hundred metres from the base of the rocky promontory that Tor Christo sat upon. Already this reconnaissance was bearing fruit. Ahead he could see three concealed artillery pits carved into the base of the hill. Rock-sheathed doors led within and, were it not for the rails that would carry the guns forward into position, he might never have spotted them.
Again he was forced to admire the cunning of the architects of Hydra Cordatus. These artillery pits were designed to remain silent and hidden until the Christo's attackers believed they had knocked out the fort's guns. Once attackers had established their breaching batteries, these guns would unleash deadly salvoes of ordnance to destroy their artillery pieces.
They were dug at an angle into the rock face, making it difficult, if not impossible, to target with counter-battery fire and Honsou realised that with this information he had a chance to prove his worth to the Warsmith.
He waved over his second-in-command, Goran Delau, and indicated the artillery positions.
'Clever,' observed Delau.
'Aye,' agreed Honsou darkly. 'It will be a devil of a job to destroy them.'
'Indeed.'
Honsou glanced round as the scrape of metal on rock sounded again, and he stifled a curse as Brakar Polonas noisily joined them.
'Why do we stop?' he asked.
Honsou didn't answer, he simply pointed towards the concealed artillery positions.
Polonas nodded, studying the positions with his practiced eye.
'We can mark their positions and shell them once the first parallel's batteries are in place,' suggested Delau. 'We can bring enough rock down to block the guns.'
Polonas shook his head. 'I do not believe it can be done with guns. Look, there is a rock canopy built across the top of the door and a ditch before them to catch any rubble that may be blasted loose.'
Honsou was impressed. He had not noticed those defences and his respect for the old man rose a fraction.
'Then we take the fight to them, and capture the guns now.'
Once again, Polonas shook his head.
'Keep your impatience in check, half-breed. We must not act in haste. Think about it. These doors lead within the rock of the fortress, most likely just to this outwork, but possibly even to the main citadel. Were we to attack now, the enemy would simply seal the tunnels beyond our means to breach and defend them with great vigour.'
'Then what do you suggest, Polonas?' snapped Honsou.
Polonas turned his gaze on Honsou and snarled, 'You must learn to respect your betters, half-breed. The first lesson of intelligence gathering is knowing how to use the information you accumulate. To act precipitously would be to alert the enemy of what we know.'
'Then what? We just ignore the fact that we have discovered these positions?'
'No, far from it. We continue as though we are unaware of their existence. Await their deployment and take the positions by storm by previously infiltrated troops. In conjunction with a frontal escalade, this will allow us to take Tor Christo in a matter of hours.'
Honsou bit back a retort as he saw the sense in what Brakar Polonas was suggesting. It was a salutary lesson and Honsou bowed his head, accepting the words of Forrix's engineer.
'Very well, we will do as you direct, Brakar Polonas' said Honsou formally.
Swiftly, Honsou contacted the remainder of his warriors and issued the command to return to the rally point. He deactivated the vox-link and was preparing to move out when Brakar Polonas turned and slipped on a loose patch of shale, the metal of his bionic leg scraping noisily between the faces of two boulders.
The Iron Warriors froze.
Tense seconds passed in the stagnant darkness as Honsou held his breath. He scrambled across to the veteran warrior as quietly as he was able and saw that his leg was wedged tight between two rocks. He cursed silently to himself and pressed his gauntlets flat against Polonas's shoulder guards.
'Be still,' he warned.
Just as he had begun to think they had not been detected, a spear of phosphorescent light streaked skyward, closely followed by a second. Both burst within seconds of one another and the plateau was suddenly illuminated by twin suns burning brightly as they slowly descended on small grav-chutes.
A cry of alarm was raised high above them and Honsou cursed aloud this time, uncaring of who heard him.
'Damn you, Polonas!' snarled Honsou, wrenching the ancient warrior from the ground. The metal of the bionic leg was wedged tightly and it was the organic components of the limb that failed first, tearing free in a wash of blood as Honsou ripped Polonas from the ground.
Polonas grunted in pain, the accelerated healing mechanism of his body stemming the flow of blood from his severed leg in seconds. Honsou shucked the man onto his shoulders and shouted, 'Iron Warriors, go! As fast as you can!' He heard the unmistakable cough of mortar fire.
Honsou knew that the first rounds would be for ranging purposes, but there would be spotters on the wall to direct subsequent volleys. They had to make as much use of this time as they could. The strobing light of the two sunflares cast lunatic shadows across the cracked ground and it took all Honsou's skill not to lose his footing as he raced from the base of the mountain. The ground rocked as mortar shells burst ahead of them, scything deadly fragments in all directions, but they were landing too long. The height of the mortars was working against the Imperial gunners now. Their elevation gave them longer reach, but also meant that it was impossible to engage targets within a certain range.
