Traitor Titan Legions - 41st Millennium: Siege of Vraks (813-830.M41) - The Siege of Vraks was an Imperial military campaign fought over the course of 17 standard years to retake the Imperial Armoury World of Vraks Prime from the heretical Forces of Chaos led by the Apostate Cardinal-Astra Xaphan of the Scarus Sector. Vraks was besieged by the forces of the Imperium of Man in 813.M41, after the attempted assassination by an agent of the Officio Assassinorum of the heretical and traitorous Xaphan. The Imperial Guard's 88th Siege Army was raised from line regiments of the Death Korps of Krieg to undertake the Siege of Vraks and bring the Renegade Cardinal down in a campaign of attrition that the Administratum's Adepts calculated would take 12 standard years to successfully conclude. At the conclusion of what became a 17-year-long campaign of attrition requiring 34 regiments of the Imperial Guard to re-take the planet for the Emperor of Mankind in 830.M41, 14 million Imperial Guardsmen had been lost and Vraks Prime's entire original population of 8 million souls had been consumed in the violence or exterminated after they fell to Chaos corruption. This campaign was, amongst other things, a prime example of the deployment of Traitor Titan Legions in support of Heretic forces in the 41st Millennium, as well as a clear display of their value to the Forces of Chaos. The Traitor Titans sought to arrive on Vraks along with the other Forces of Chaos on the transport vessel Aharon's Bane. Although the Imperial Navy managed to damage the ship, the vessel survived planetfall and crashed west of the Chaylia Plateau, tearing a great gouge into the surface of Vraks and leaving its remains scattered across kilometres of the planet's surface. The Imperial naval force's commanders had hoped that the damage inflicted would see the craft destroyed, but this was not to be. Although many died as a result of the landing, far more survived, and warbands disgorged from the ship's ravaged hull were soon preparing for battle -- amongst them the dreaded Titans of the Legio Vulcanum I. From there, the Chaotic reinforcements moved to engage the Imperial Guard corps besieging the defensive lines surrounding the Citadel of Vraks. The Titans soon proved their worth once they engaged the Imperial forces of the 101st Death Korps of Krieg Regiment, opening fire at long range and devastating the Krieg armoured columns sent to face the Traitor onslaught. Clouds of brown dust stirred by the advancing tanks turned to blue-black smoke as the vehicles were smitten by the fury of Turbo-Lasers, Gatling Blasters and Volcano Cannons mounted on the massive war machines. The attempts to retaliate were all for naught, as the armour-piercing shells deflected off the Titans' Void Shields with electric blue flashes. Even repeated blasts of an Imperial Shadowsword super-heavy tank's mighty ordnance flickered harmlessly off the Titans' shields. For all its efforts, in response the great tank was disarmed by a single shot of a Turbo-Laser, and its crew immolated by a successive blast. Ultimately, the Imperial force sent to halt the Heretics' reinforcements failed. The defeat of the 101st Krieg Regiment meant that the Death Korps could no longer maintain a ring surrounding the fortress. The 19th Krieg Regiment had been ordered to relocate and face this grim threat alone to buy the time needed by Imperial forces sieging the eastern side of the fortress to abandon posts and move to a defensible position. These manouvres would see the regiment cut off. In such circumstances, the 19th could not have hoped to last long, especially if the Archenemy made use of their Titans. Such desperate measures were required just to save the Imperial campaign from complete failure.  	 	<a href="https://static.wikia.nocookie.net/warhammer40k/images/2/27/Legio_Vulcanum_Chaos_Reaver.jpg/revision/latest?cb=20120607182443" class="image"><img alt="Legio Vulcanum Chaos Reaver" src="https://static.wikia.nocookie.net/warhammer40k/images/2/27/Legio_Vulcanum_Chaos_Reaver.jpg/revision/latest/scale-to-width-down/250?cb=20120607182443" decoding="async" loading="lazy" width="250" height="189" class="thumbimage" data-image-name="Legio Vulcanum Chaos Reaver.jpg" data-image-key="Legio_Vulcanum_Chaos_Reaver.jpg" data-relevant="1" data-src="https://static.wikia.nocookie.net/warhammer40k/images/2/27/Legio_Vulcanum_Chaos_Reaver.jpg/revision/latest/scale-to-width-down/250?cb=20120607182443" /></a> 	 		 			 		 		 		 			A Reaver-class Titan of the Legio Vulcanum I on Vraks. 		 	  These defeats prompted the commanding Lord Militant Obscurus to replace the 88th Siege Army's command staff. The Imperial Guard officer eventually chosen for this task was Marshal Arnim Kagori. His first action, after assembling his staff, was to gather help for the beleaguered Krieg regiments on Vraks. In addition to securing the aerial support of the Imperial Navy and more manpower from Krieg, Kagori sought to be able to counter enemy Titans, and to this end petitioned the Legio Astorum -- the Warp Runners -- for help. The venerable lords of Lucius, the Legio Astorum's home Forge World, agreed. A battlegroup of Titans was deployed to support the 88th Siege Army, as only they could hope to match the firepower of the Traitor Titans. After their rites of battle were complete, they embarked upon their transport vessels and set off for Vraks. Soon, Kagori's reinforcements arrived on the planet, and amongst them was the Legio Astorum battlegroup, comprising 10 Reaver-class Titans and 12 Warhound-class Titans led by the venerable High Princeps Rand Drauca, ready to face the Traitors on the battlefield and resume the war that had been ongoing for ten thousand standard years. The Warp Runners supported the Marshal's new offensive to great effect, and very soon the Legio Vulcanum I took to the field to face them. Both sides were initially evenly matched, and the Legio Astorum suffered its first loss of the campaign -- the Reaver-class Titan Invigila Alpha. The Vraksian Renegades were heavily battered by Kagori's fresh forces, and were only able to hold the tide owing to the assistance of the Traitor Titans. However, as the fighting progressed, the Legio Vulcanum I found itself outmatched by its Collegia Titanica counterparts, and was eventually forced to pull back and regroup after -- according to the Warp Runners -- losing 12 war machines, a feat for which the Legio Astorum paid with the disabling of 11 of its own Loyalist Titans. 	 	<a href="https://static.wikia.nocookie.net/warhammer40k/images/b/b2/Rhino009.png/revision/latest?cb=20120415002847" class="image"><img alt="Rhino009" src="https://static.wikia.nocookie.net/warhammer40k/images/b/b2/Rhino009.png/revision/latest/scale-to-width-down/250?cb=20120415002847" decoding="async" loading="lazy" width="250" height="170" class="thumbimage" data-image-name="Rhino009.png" data-image-key="Rhino009.png" data-relevant="1" data-src="https://static.wikia.nocookie.net/warhammer40k/images/b/b2/Rhino009.png/revision/latest/scale-to-width-down/250?cb=20120415002847" /></a> 	 		 			 		 		 		 			Legio Vulcanum I Warhound-class Titan supporting Chaos Space Marines on Vraks. 		 	  The Titans clashed once more at the Red Scorpions Space Marine Chapter's first landing site. The Space Marines arrived on Vraks heeding Marshal Kagori's plea for aid following the Departmento Munitorum's unfavourable review of the campaign and its subsequent downgrading in reinforcement and resupply priority. The Red Scorpions opted to descend upon the planet's surface into the breach located in Sector 57-44, where they deemed their assistance would be put to best effect. A plan was agreed upon, which would see a special battlegroup from the 88th Siege Army's 11th Assault Korps supported by Legio Astorum Titans exploiting the breach once the Red Scorpions succeeded in securing the area. The enemy had contingency plans for assaults on the breach, and moments after the Space Marines' arrived they were already fighting the forces of the swarming Heretics, including Traitor Titans. Guardsmen rushed to aid the beleaguered Red Scorpions and trailing behind them were the Warp Runners, who eagerly engaged the Legio Vulcanum I, seeking to repeat their previous success. The great war machines engaged in vicious duels as the fighting continued around them, and despite suffering the loss of even more machines, the Legio Astorum triumphed, forcing the Traitor Titans to retreat. High Princeps Rand Drauca could celebrate another victory over the despised Legio Vulcanum I on his Titan's honour banner. Imperial records bear no mention of further actions undertaken by the Traitor Titans on the battlefield, though, it can be presumed that they continued the fight, as they are known to have defended the Citadel of Vraks itself. The number of Titans deployed by the Traitors on Vraks is unknown, although the Legio Astorum claims to having destroyed fourteen, losing nine of theirs in the process. If this is true, then the Legio Vulcanum I paid a heavy price for their involvement. How the remaining Traitor war machines -- if there were any -- escaped from Vraks following the eventual Imperial victory is also unknown. Of the Legio Vulcanum I's actions during the campaign perhaps only one thing is certain -- they sowed destruction and terror wherever they went.Badab War (912-913.M41) - The Chapter Master of the Astral Claws, Lufgt Huron, the "Tyrant of Badab," sought to have the Badab Sector secede from the Imperium in protest against the Imperium's continued attempts to use the resources of the Badab Sector outside the region rather than dedicating them fully to the defeat of the forces of Chaos and xenos threats that emerged constantly in the Maelstrom Zone. This major rebellion involved several Space Marine Chapters who turned Renegade and sided with the Tyrant in his mad cause. The world of Angstrom was a highly militant minor Forge World containing a significantly independent Adeptus Mechanicus presence situated at the edge of the Maelstrom Zone, and by this web of kinship the Legio Crucius became involved in the Badab War's savage closing campaigns. The Legio Crucius forces deployed to the siege of Badab Primaris itself, comprised of three full maniples of Titans, some fifteen war machines in all, commanded by the Warlord-class Titan Hell's Daughter and High Princeps Cadmon Krom. The Titans' principal task in the battle was to smash heavy defence points in Badab Primaris' hive cities and industrial zones and crush major pockets of resistance when encountered, a mission they undertook with great relish, fully living up to their Legio's long-standing reputation as savage city-breakers and world burners. The Legio Crucius accounted for untold casualties and devastated the remaining Secessionist heavy armoured forces. The Titan Legion suffered only three losses during the engagement despite the heavy resistance they encountered, and managed to recover all but one of their wrecked Titans in the anarchic retreat from the planet by the Loyalist forces.Third War for Armageddon (998.M41) - Ork Warlord Ghazghkull Mag Uruk Thraka launched a second and even more massive Ork WAAAGH! to conquer the Imperial Hive World of Armageddon in 998.M41. As the battles raged on the planet, Ghazghkull unleashed another of his carefully prepared surprises. Incredibly, dozens of Ork Roks (asteroid fortresses) began to descend from orbit. The Roks 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. Besides their formidable armaments, the Roks contained giant teleport arrays. These were employed to teleport down Ork reinforcements, including Gargants and Greenskin heavy artillery, in an endless stream. Commissar Yarrick personally led attacks by regiments of Cadian Shock Troops supported by the Titans of the Legio Ignatum and Legio Metalica, which destroyed several of these fortresses. During a ten-day battle that raged over the Diabolus manufactorum complex and proved to be one of the most fierce of the Third War for Armageddon, Titans from the Legio Crucius engaged the Gargants of the Warlords Burzuruk and Skarfang. Six Titans and eight Gargants were utterly destroyed in the fighting and many others needed many solar months of repairs before they could fight again. The Diabolus complex was wrecked during the battle, its foundries and machine shops blasted apart or crushed underfoot by the giant fighting machines.13th Black Crusade (ca. 999.M41) - When the forces of Chaos assaulted the world of Cadia during the 13th Black Crusade in ca. 999.M41, the Titan Legions stationed on the worlds surrounding the Eye of Terror helped in the defence of that beleaguered Imperial Fortress World. Many other Titan Legions, a number of them unleashing their entire strength, were transferred there to face the Chaos onslaught.
