Legio Astorum - Notable Campaigns: Kamenka Troika Campaign (Unknown Date.M30) - Sometime during the middle years of the Great Crusade, the Legio Astorum fought alongside the Thousand Sons Legion and a Lifehost of Pan Pacific Eugenians drawn from the Imperial Army. The Emperor had issued the writs of war commanding this combined Imperial task force to undertake the difficult task of driving the savage Greenskin menace from the three satellite planets (collectively known as the Kamenka Troika) of the world of Kamenka Ulizarna -- a world originally claimed by the Mechanicum of Mars. The savagery of that war, the slaughter and relentless, grinding attrition had left tens of thousands dead in its wake. Imperial forces were finally victorious after two years of fighting and earned a score of honours for their war banners. Victory had been won, but the cost had been high with the loss of nearly an entire Warp Runners' detachment of Titans. With the successful conclusion of the campaign the Thousand Sons honoured the Legio Astorum by recovering Canis Vertex, the last Warp Runners Titan to fall. They repaired and restored the great war machine and then had it transported to their homeworld of Prospero where it was mounted upon the pyramid of the Legion's Pyrae Cult of Sorcerers.Battle of Tallarn (010-012.M31) - The Legio Astorum is known to have fought in various engagements during the Horus Heresy, including the famed Battle of Tallarn. Perturabo, Primarch of the Iron Warriors, launched an all-out planetary invasion of the verdant Imperial staging world of Tallarn, his Legion bolstered by dozens of allied Traitor Imperialis Auxilia regiments, the Traitor Titans of the Legio Krytos and the Knights of House Caesarean. Both the Loyalists and Traitor high commands were taken by surprise by Perturabo's actions and the invasion quickly escalated after he ordered Exterminatus upon the world, scouring its surface of living matter by way of a voracious Life-eater viral barrage. While the population of the world was all but wiped out, many defenders survived thanks to extensive subterranean shelters. The ensuing campaign was fought between vast formations of Imperial Army and Solar Auxilia tanks, the Titans of the Legio Gryphonicus, the Knights of House Megron, the indentured Automata of the household army of the Rogue Trader Sangrea as well as armoured forces of the Iron Hands, Imperial Fists, White Scars and Ultramarines Legions. No infantry can survive in the poisoned wastes, and the war quickly draws in other forces from across the region, including the Titans of the Legio Astorum. It soon became painfully clear to the Imperial forces the futility of fighting over a destroyed planet, but by then there was no turning back. Though it was not known at the time, the Traitor Legion was motivated to attack the world beyond their mere appetite for destruction as Tallarn was the site of a hidden and potentially powerful Chaos artefact. The toxic environment of the world made it impossible for infantry troops to operate outside of their protective shelters, and so the only available option was to make use of armoured tank warfare and the support of the Titan war machines of the Legio Astorum. The Warp Runners fought their traitorous kin from the infamous Legio Mortis Traitor Titan Legion, while the largest tank battle in human history erupted on the surface of Tallarn, involving some 10 million armoured vehicles. By the end of this brutal conflict, the Iron Warriors were defeated, and the wreckage of over a million tanks littered the sands.Battle of Beta-Garmon, "The Titandeath" (006-013.M31) - The Legio Astorum took part in the long and savage Beta-Garmon campaign, which included hundreds of war zones across dozens of worlds. During this conflict, the Legio Astorum was supported by the Knights of House Hawkwood, House Mortimer and House Terryn. Even before the greater armies of the Warmaster Horus reached the star cluster, the battle lines had long since been drawn, and fighting had been going on for many Terran years. It was a cauldron of battle that would consume millions of lives before its end and see the demise of entire Titan Legions, earning this campaign the dire moniker of the "Titandeath." The Beta-Garmon Cluster, also known as the gateway to the throneworld of Terra, was the last hurdle that the Warmaster Horus' forces had to overcome before they reached the Imperium's capital world. Heavily fortified by the Loyalists, Beta-Garmon would become one of the greatest and bloodiest battles of the Horus Heresy, as well as one of the longest-lasting.Battle of Nycron (010.M31) - Under the direction of the Imperial Fists Primarch Rogal Dorn, a Loyalist battlegroup led by elements of the Salamanders Legion, and supported by thirty regiments of Solar Auxilia and a strike force of Legio Astorum Titans, engaged the Emperor's Children Millennial assigned to garrison the Beta-Garmon System on the edge of the Segmentum Solar. The Emperor's Children contingent was surprised at Nycron City on Beta-Garmon II and after a hard-fought battle, the Emperor's Children, along with their Legio Mortis allies at Beta-Garmon III, were driven out, placing the system into Loyalist hands and triggering within the year the first in an escalating series of Traitor counterattacks.Scouring of the Ollanz Cluster (012.M31) - The Warmaster Horus' advance on Terra reachedf the Ollanz Cluster, encountering Loyalist reinforcements bound for Beta-Garmon rearming and refuelling at the Borman System. The Loyalist fleet rapidly redeploys to oppose the Traitors' advance and to protect the valuable resource worlds of the cluster. The turning point of the brief but intense conflict comes at Borman IV, when a Legio Astorum demi-legio launches a daring offensive towards the world's beleaguered capital city. The crucial Titan battle takes place in the volcanic Yrevendi Desert immediately to the north of the capital, as Princeps Seniores Varr Harax leads a surprise thrust through rough terrain at a weak point in the Legio Fureans lines, accompanied by ground forces drawn from the Iron Hands Legion. The Legio Fureans, also called the Tiger Eyes, having been drawn away by a bold diversionary attack, are annihilated by the Warp Runners, who are able to break through Traitor Emperor's Children Legion lines and reinforce the beleaguered capital. Ultimately, Borman IV and the entire Ollanz Cluster are delivered from the Traitors' possession, allowing for Loyalist forces to be redeployed to their original destination at Beta-Garmon.Purge of the Contqual Sub-Sector (812.M41) - The Legio Astorum 's Titan Battlegroup Praxes, under the command of Princeps Firax Lopi, participated in the final campaign of the Purge of Contqual Sub-sector, fighting alongside the Iron Hands Space Marine Chapter and a large force of Imperial Guard regiments and heavy armour. As far as Imperial scholars can determine, the Chaotic taint of the Contqual Sub-sector began late in the year 812.M41 when the Contqual High Governor fell easy prey to the corruption of the Chaos God of Pleasure, Slaanesh. From the High Governor's court on the world of Shardenus the taint spread quickly and within a single month the entire sub-sector seethed with the corruption of Chaos. The cleansing of Contqual was tasked to the Iron Hands who have always burned with hatred for Chaos in all its myriad forms since the disaster on Istvaan V. The Iron Hands stormed into the Contqual Sub-sector with a speed akin to chained lightning, seizing several planets before resistance could even be organised by the region's Forces of Chaos. In short order, the Iron Hands of Clan Raukaan, under the command of Lord Clan Commander Arven Rauth, moved against the focal point of the Chaotic taint in Contqual, the Hive World of Shardenus, where the world's large body of Chaos Cultists, making use of forbidden sorcerous rituals, had torn a hole straight through the space-time continuum and into the Warp. Lord-General Raji Nethata, the overall Imperial commander of the forces on Shardenus, requested Titan support from the Adeptus Mechanicus. The Legio Astorum responded by sending a Warlord-class Titan and four other war machines to take part in the final campaign on the sub-sector's capital world. Though massively outnumbered and sustaining significant losses, the Imperial forces cut through the Heretics and their daemons like an unstoppable storm. The world was brought to heel in short order with the rest of the sub-sector falling to the fury of the Imperial forces with equal speed, the citizens of many worlds turning on their tainted masters and pleading with the Iron Hands for mercy. But the sons of Ferrus Manus are not known for their forgiveness and the Chapter fell on the worlds of the sub-sector with a cleansing wrath, executing one in every three civilians in a great and bloody purge, which the Chapter intended to serve as a righteous punishment for allowing the taint of Chaos to sweep over the worlds of the Contqual. In the wake of their bloody passing, the surviving Imperial citizens of the Contqual Sub-sector became amongst the most devout faithful of the God-Emperor in the galaxy.Siege of Vraks (813-830.M41) - During the infamous Siege of Vraks, the Legio Astorum Titan battlegroup provided the Imperial 88th Siege Army with its heaviest armour and firepower. Deploying 22 Titans of the Reaver and Warhound classes, the commitment of this battlegroup in support of the 12th Line Korps was the decisive factor in breaking through the inner defence lines during the Kagori offensive on Vraks Prime. The High Princeps Rand Drauca and his Warp Runners continued to support the campaign on Vraks on numerous occasions, and were heavily engaged again when the Red Scorpions Chapter captured the breach in the curtain wall, matching weapons and armour with the Traitor Titans of the Legio Vulcanum I. The exact number of enemy Titans was not identified, although post-battle reports claim that 14 enemy Warhound-class Titans and Reaver-class Titans were destroyed during the campaign. As such, the Legio Vulcanum paid a heavy price for its involvement, and the Legio Astorum can claim a famous victory over their ancient enemy.13th Black Crusade (999.M41) - When the forces of Chaos assaulted the world of Cadia during the 13th Black Crusade in 999.M41, the Legio Astorum was one of the Loyalist Titan Legions of the Collegia Titanica to help in the defence of that beleaguered Imperial Fortress World. The Warp Runners fought in multiple campaigns during this Black Crusade, including:Amistel Majoris - The world of Amistel Majoris (located in the Agripinaa Sector was besieged by Plague Marines of the infamous Death Guard Traitor Legion. Despite the planet being reduced to a mass of putrefying corpses, the Imperial Guard's 83rd Regiment of the Drookian Fen Guard helped bolster Imperial forces with a masterful defensive strategy which kept the planet in Imperial hands until the arrival of additional Imperial forces in the form of the Howling Griffons Space Marine Chapter and the Titans of the Legio Astorum.Demios Primary - When the Skitarii forces of the Adeptus Mechanicus' Forge World of Demios Primary were scattered by the combined Chaos forces of the Black Legion and the Extinction Angels, it was the Imperial defenders of the Legio Astorum and the Space Marines of the Black Templars Chapter which liberated the world's forges.
