Legio Metalica - Notable Campaigns: First Scouring of Jardingris (Unknown Date.M30) - The greatest and most portentous battle the Knights of House Vornherr fought in during the Great Crusade, it was on the grave-world of Jardingris that the house first took to the field of battle under the overall command of Primarch Roboute Guilliman as part of a combined force consisting of twelve full chapters of the Ultramarines, the Legio Metalica Titan Legion, ten cohorts of the Solar Auxilia and scores of Excertus Imperialis line regiments. They were joined by the Conquestor companies of Rogue Trader Kohnwallis. The war against the anti-human revenant organisms of Jardingris was a bitter one indeed, and by its end the necrogenic xenos strain had paid for its crime of existence with its utter extermination. The victory came at the cost of a dozen Titans and a hundred Knights, tens of thousands of human infantry and almost three thousand warriors of the Legiones Astartes.Ruin of Maerdan (008.M31) - In the third year of the Horus Heresy, the Imperial colony world of Maerdan on the edge of the Segmentum Solar became a savagely contested frontline between the forces of Loyalist and Traitor. Maerdan's citites beomce flaming ruins and its once verdant plains are turned to barren wastes, crushed and scoured by the futy of the battle as the Loyalist Titans of Legio Metalica, Legio Gryphonicus (War Griffons), and Legio Destructor (Beasts of Steel) clash with the Traitors of Legio Mortis (Death Heads), Legio Astraman (Dread Lances) and Legio Vulturum (Gore Crows). The Ruin of Maerdan, as the campaign came to be known, was one of the largest Titan battles of the early Horus Heresy, with more than 200 Titans taking ot the field against each other. Heavy losses are incurred by both sides and as the war moves on, it leaves a shattered world behind, with neither Loyalist nor Traitor able to claim true victory.Imperial Muster at Beta-Garmon (012-013.M31) - For reasons only understood later in the war, the Ruinstorm that had been invoked by Lorgar, primarch of the Word Bearers, several standard years earlier during the Battle of Calth, began to abate across vast swathes of the galaxy. Loyalist high commanders were able to utilise the potent astropathic relay at Beta-Garmon to contact and recall formerly lost or stranded forces from across the war-torn reaches of the northern Imperium. The Imperial Muster at Beta-Garmon rapidly escalated into the largest gathering of Loyalist might since the early years of the war, a concentration of forces so mighty that the Traitors had to respond in kind. The resulting clash of arms would become known as the Great Slaughter, a theatre of war of such scale that it would encompass the "Titandeath" and the Sea of Fire campaigns, each major campaigns in their own right. By its end, both sides were so badly bled that their only remaining option for ultimate victory was to force a final, decisive confrontation. As history related, the final battle would be fought at Terra, but only after the weighty butcher's bill of the Great Slaughter was paid in full.Second War for Armageddon (941.M41) - The Legio Metalica is most famous for the tragic part it played in the Second War for Armageddon. The Iron Skulls were stationed on that Hive World to protect its vital industry. At the time, Armageddon suffered beneath the rule of its foolish and erratic Overlord, Herman von Strab, who refused to believe warnings of an impending invasion of the largest Ork WAAAGH! seen in centuries. Failing to heed the dire portents, Armageddon was invaded in 941.M41 by the mighty Ork Warlord Ghazghkull Mag Uruk Thraka. Ghazghkull smashed through von Strab’s inadequate defences. Desperate, the Overlord commanded the Legio Metalica to perform the impossible task of stemming the massive greenskinned tide of Orks from overrunning the planet. Holding temporary command of the Legion after the death (suspected to be an assassination) of its Grand Master, Princeps Senioris Kurtiz Mannheim reluctantly obeyed the Overlord. By Imperial law he was required to perform his duties, and so Mannheim put on his best dress uniform, told his family goodbye and prepared to sell his life dearly. Unable to betray his oath of loyalty to the Emperor, Mannheim climbed aboard his Titan Steel Hammer and led his battle group to their inevitable destruction. The Legion fought long and hard, and Steel Hammer accounted for the destruction of three Ork Gargants before it was severely damaged. Not going down without a fight, Mannheim ordered his war machine to be taken into the centre of the Ork forces before his Titan's reactor melted down. When the reactor detonated, a half dozen Gargants were taken out, delivering a powerful message to Ghazghkull that the Collegia Titanica would never rest whilst a single Ork lived to taint Armageddon’s soil. But outnumbered three to one, the Legio Metalica was severely outmatched. The Legion was almost completely wiped out and took no further part in the Armageddon campaign. At the end of the campaign Princeps Senioris Mannheim was posthumously awarded the Emperor’s Star for his bravery and loyalty to the Imperium. The Legion was rebuilt and has since won acclaim in every campaign it has fought in due to its dedication and determination. To date the Legio Metalica 's tally of victories is unsurpassed by that of any other Titan Legion. Mannheim remains a shining example of the dutiful warrior to all in the Imperium.Third War for Armageddon (998.M41) - Once again, the Legio Metalica played an important role in the defence of Armageddon from the Orks. In 998.M41, Ghazghkull Thraka returned, leading a second, larger WAAAGH! to smash and subjugate the humans of Armageddon. The famous Commissar Yarrick and many other Imperial heroes who had fought in the previous war fifty-seven years earlier were recalled to defend the Hive World once again. Ork Roks (makeshift asteroid fortresses) made landings in the verdant equatorial jungles of the world and across the continents of Armageddon Primus and Secundus. Many were lost to ground fire or accidents but each one that survived became a bastion for the Orks, a rallying point and a ready-made fortress. As well as their huge gun and missile batteries, the Roks contained giant teleport arrays like those first used by Ghazghkull during his Piscina Campaign. These were employed to teleport down Ork reinforcements, including Gargants and heavy artillery, in an endless stream. Fighting alongside the Legio Ignatum (Fire Wasps), Regiments of Cadian Shock Troops and elements drawn from various Space Marine Chapters, the Legio Metalica was personally led by Commissar Yarrick in the destruction of several of the fortresses.13th Black Crusade (999.M41) - When Abaddon the Despoiler and his forces of Chaos assaulted the world of Cadia during the 13th Black Crusade in 999.M41, the Legio Metalica was one of the Loyalist Titan Legions of the Collegia Titanica to help in the defence of that beleaguered Imperial Fortress World by providing a battlegroup to assist in holding back the tidal wave of Chaos fanatics.Diamor Campaign (999.M41) - The Legio Metalica served alongside the 1st, 2nd and 5th Companies of the Blood Angels Chapter and the Knights of House Raven on the world of Amethal in the Diamor System. The Imperial forces succeeded in driving back the forces of the Black Legion and the Crimson Slaughter from Amethal and the wider system, but not before the Heretic Astartes enacted a sorcerous ritual with the aid of the artefact known as the Banshee Stone that weakened a prison for daemons on Amethal. If this "daemon cage" could not be strengthened with the aid of the Grey Knights, the strategic Diamor System would be lost to the eruption of a new Warp rift and a daemonic assault that would greatly assist Abaddon the Despoiler's 13th Black Crusade.Subjugation of Nicomedua (Unknown Date.M42) - Where the Imperium of Mankind was torn asunder by the opening of the Great Rift, the domains of the Machine God suffered not only from disrupted supply chains and troublesome Warp Storms, but also from a rise of dissension within their own ranks. On Nicodemua, one of Metalica's many tributary worlds, large portions of the Martian Priesthood and Skitarii forces were swayed by the Dark Mechanicum, embracing a new interpretation of the Omnissiah's words known as the Tangential Path. Declared Heretek by its patron Forge World, Nicodemua was promptly assailed by the countless ranks of the Astra Militarum which, while able to force a landing on the rebellious world, was unable to fully purge its corruption. After three Terran years of conflict, the reclamation of Nicomedua had reached a stalemate. Having fortified the lands around the already impressive fortress of Az Khalak, the Hereteks had pressed back several Imperial offensives and the tacticians and Lexmechanics of the Imperial Guard agreed that the expected casualties would number in the millions, rendering the whole campaign nonviable. Petitioning the Legio Metalica for aid, the Imperial commanders were relieved to be reinforced by Battle Group Casus Belli, a force strong enough to break the stalemate and seize Az Khalak within a single solar day. Led by the Imperator-class Titan Casus Belli, the forces of the Legio Metalica marched right into the enemy's trap: sacrificing its best troops and even Az Khalak itself, the Hereteks were able to isolate the Casus Belli from the rest of the battle group while trying to seize it from within. At the same time, the Hereteks were reinforced as their allies from the Legio Fureans landed in Nicodemua's highlands and initiated a potentially devastating counteroffensive. Isolated and led into error by the corrupted bridge-crew of the Casus Belli, several Titans of the Legio Metalica were destroyed until the internecine conflict within the Casus Belli was resolved. With the victory of the Loyalist crew, the Casus Belli’s allegiance was restored. With the addition of its tremendous firepower, the Legio Fureans was quickly vanquished and Nicomedua restored to the true path of the Omnissiah.Charadon Campaign (Unknown Date.M42) - The Charadon Campaign began after the end of the Noctis Aeterna in the local region, when Typhus the Traveller seized his chance to invade the Forge World of Metalica and plunged the Charadon Sector into war, seeking to claim it for the forces of Nurgle, the Plague God. The Legio Metalica played a key role in the defence of their homeworld.Battle of Raukos (Unknown Date.M42) - The Legio Metalica participated in the Battle of Raukos, one of the last battles of the first phase of the Indomitus Crusade. On the world of 108/Beta-Kalapus-9.2 in the Pit of Raukos, the orbital assault was led by Primaris Space Marines drawn from the Unnumbered Sons. They were not alone in the first wave, accompanied by Firstborn Space Marines from the Silver Skulls. The Astartes landed on a fortress-complex manned by the Heretic Astartes of the Iron Warriors. The first Imperial troops to hit the planet's surface were Primaris Inceptor Squads dropped from orbit. They moved onto the roofs of the Iron Warriors' fortresses to neutralise their anti-aircraft batteries, allowing for waves of Imperial drop ships to arrive in their wake. Heavy vehicles such as Repulsors were delivered as well as Titans from the Legio Metalica. These forces quickly overwhelmed the remaining Traitors, and the fortress ultimately fell 5 solar hours after the elimination of its air defences.
