Iron Lords - Notable Campaigns: Grendl Stars Campaign (Unknown Date.M38) - The Iron Lords were responsible for driving back the hyper-aggressive xenos known as the Barghesi to their home in the Grendl Stars.Judgement of Hellenus (801.M41) - Inquisitor Hector Rex assumed direct control over the entire 279th Assault Armada of the Navis Imperialis and ordered the mutant population of Hellenus purged for crimes against genetic purity. At the height of this purge, a combined strike force consisting of Space Marines form the Iron Lords, Skull Bearers and Sons of Guilliman Chapters was gathered together to confront the mutant abominations holding the enemy capital. During this confrontation, the Iron Lords contingent became tainted by the mutants' hideous gene-taint, forcing their fellow Space Marines to purge them as well.Cleansing of Eurydice (Unknown Date.M41) - Four squads of the Iron Lords' 3rd Company assaulted the nesting-crypts of a previously unknown xenos species attacking the frontier worlds of the Imperium along the Trailing Marches of the Eurydice Sector. The alien species was exterminated.Hive Fleet Kraken (992.M41) - The Iron Lords have so far been successful in preventing the Tyranids of Hive Fleet Kraken from entering the Grendl Stars and thus harvesting the genetic potential of the vicious Barghesi species.Defence of Valedor (997.M41) - The Tyranid Hive Fleet Leviathan overran the Ecclesiarchy world of Valedor in a matter of solar hours, slaughtering the entire population of pilgrims and Adeptus Ministorum priests, as well as overwhelming a battle barge of the Iron Lords Chapter. A small force of battle-sisters from the Order of the Sacred Rose represented the only Humans to bear witness to the event, having barely fought their way clear of the carnage.Zeist Campaign (999.M41) - The Iron Lords answered the summons of Marneus Calgar, the Lord Macragge and Chapter Master of the Ultramarines, for a force of Space Marines to throw back the expansion of the T'au Empire in the Eastern Fringe in 999.M41. The Chapter participated in the successfully punitive Zeist Campaign.Second Relief of Mordian ("Iron Crusade") (Unknown Date.M42) - As Imperial forces withdrew from the Stygius Sector during the Invasion of the Stygius Sector, the Iron Hands refused to retreat and instead gathered on Mordian, itself under siege from Chaos forces. Alongside a mere dozen or so regiments of the Astra Militarum's Mordian Iron Guard, the Iron Hands sought to reforge themselves and purge the weakness they had displayed earlier in the campaign. During the siege the Iron Hands were joined by allies enraged by the defeatism of the Imperial forces, among them the Brazen Claws, Fire Lords, Silver Skulls, Sons of Medusa, and Iron Lords in what became known as the "Iron Crusade." They arrived on Mordian to find the planet terrorised by a Night Lords warband under the command of Ahrak Deathshriek and his Raptor hordes. Deathshriek planned to use the terror his Heretic Astartes created in the Mordian population to power a sorcerous Chaos ritual that would plunge the entire world into the Warp. The Iron Hands and their allies struck with customary bluntness, emerging without warning from the Warp and engaging the Traitor fleet in orbit and launching a Drop Pod assault on Mordian's capital. Clan Avernii under Iron Captain Caanok Var led the charge and Deathshriek drove his Chaos Cultists into the Iron Hands' guns. One by one, the remaining Iron Hands Clan Companies joined the battle and Deathshriek was wounded in single combat by Caanok Var. Even as the Iron Hands' drop zone came under fresh assault from the Traitoris Militarum Benedictian Guard and the Cult of the Whispered Word, Renegade warlords from across the sector united in their realisation that the Iron Hands could be wholly destroyed. With the Loyalist assault faltering, Deathshriek claimed victory as he led his fleet against the Iron Hands in space, outnumbering their warships three to one. It was at this point that the Iron Hands Successor Chapters arrived. Deathshriek's armada was caught in disarray by the Loyalist reinforcements and crushed. The newly-arrived Loyalist warships rained obliteration below on the Mordian populace. The orbital bombardment seemed indiscriminate, but nothing could have been further from the truth. The tactical doctrine known as "Hammer and the Storm" had been pursued planetside as well as in the trackless void, the Iron Hands' assault calculated to stir the Renegades and Traitors into reckless deeds. What had seemed a faltering Loyalist advance had merely paused while the Iron Hands Techmarines laboured to erect planetside void shields and reinforce the capital city's surviving bunkers. Thus the Iron Hands and those portions of the Mordian populace they deemed worthy of survival endured the orbital firestorm. Their foes, caught in the open and drunk on the prospect of their imminent victory, were not so fortunate. In a little over one solar hour's bombardment, the Chaos hold on Mordian was broken for the second time. Eventually other Imperial reinforcements arrived from Cypra Mundi and the Iron Crusade was able to not only push the Chaos forces off Mordian, but to counterattack Chaos garrisons on nearby worlds. The Iron Hands' governing Iron Council then unleashed a second phase of the campaign, with a plan to scour the surviving worlds of the Mordian System of their Chaos presence and wrest the refineries and orbital shipyards of the neighbouring Kharvos System from Chaos. At present, the campaign is ongoing.War for the Aberrus System (Unknown Date.M42) - Captain Nikeras of the Iron Lords' 2nd Company led a strike force composed of elements from the 2nd, 8th and 10th Companies to the Aberrus System alongside forces drawn from the Lamenters, Knights of the Raven and Scythes of the Emperor Chapters. There, the Adeptus Astartes served as crucial reinforcements in defending the system from an assault by a tendril of Hive Fleet Kraken. While the Space Marines helped to stabilise the ongoing conflict and raise Imperial morale, they did not realise that Inquisitor Shalisha Talaris of the Ordo Xenos had learned from her void watchers that a second tendril of the Kraken, twice the size of the first, was about to assault Aberrus. She feared that if the Tyranids could not be defeated, the hive fleet would sweep into the Grendl Stars and claim the genetic material of the hyperviolent Barghesi for themselves, putting the fate of the entire Eastern Fringe at risk.
