Changes

*'''143.[[M41]]:''' The [[Jorun Retaliation]] — En route to the [[Gothic War]] an Imperial Battlegroup, the [[15th Heraklion Ironclads]], turned on their [[Commissariat]] attachment and went renegade. Investigations into this turn of events uncovered the foul Xenos taint of [[Dark Eldar]], who had managed to ensnare and corrupt [[General]] [[Jorun]] and his command structure. Jorun and his fleet raided planet after planet, enslaving whole populations for their masters. The full Howling Griffons Chapter (about 8 Companies worth of Marines) was given command of the strike force, with support from the [[Ultramarines]] and [[Sons of Orar]] Chapters. Initial contact was made as the traitor forces were landing on [[Asturia]]. With no armour unloaded, it became a massacre, with over 5,000 Guard dying in an hour. The Howling Griffons' [[4th Company (Howling Griffons)|4th Company]], led by [[Chaplain]] [[Armand Titus]], led the final strike on Jorun's forces, fighting through Jorun's [[Ogryn]] cadre as well as [[Dark Eldar]] troops. Titus delivered the killing blow to Jorun, while slowly succumbing to poisoned wounds and sealing the fate of the Heraklion Ironclads.{{Fn|7b}} The campaign was not completed before the Howling.{{Fn|44a}}

*'''857.[[M41]]:''' [[Lazar Blockade]] — The Howling Griffons' fleet, along with 4 other Space Marine Chapters, overwhelmed and obliterated the main [[Tomb World]]. However, secondary bases throughout the system suddenly came to life.{{Fn|10}}

*'''905-906.[[M41]]:''' Shortly before the [[Badab War]], the Howling Griffons' [[4th Company (Howling Griffons)|Fourth Company]] along with parts of their [[6th Company (Howling Griffons)|Sixth]], [[10th Company (Howling Griffons)|Tenth]] and [[1st Company (Howling Griffons)|First]] Companies carried out a lengthy search and destroy campaign within the [[Caradryad Sector]]. It can be safely assumed that a large number of planetary assaults were carried out during this action as they were severely lacking in [[Thunderhawk]]s and [[drop pods]] when answering the call for aid in the [[Badab War]] as they had not had the chance to return to [[Mancora]].{{Fn|7b}}

*'''906-909.[[M41]]:''' [[Badab War]] — The Howling Griffons, along with the [[Novamarines]], responded to calls for aid. Having just finished a campaign in the [[Caradryad Sector]], the Howling Griffons' task force was no more than 250 Space Marines and had insufficient planetary assault resources to aid in front line assaults. As a result, their initial engagements were to carry out garrison duties or convoy protection.{{Fn|39}} Their largest deployment was to garrison the airless moons in the [[Khymara]] system, rebuilding old listening posts as staging areas for later in the war. Unfortunately in 4.003.907.M41,{{Fn|7a}} this posting put them in the path of the [[Executioners]] who were coming to aid the Secessionists as part of their blood oath to Huron.{{Fn|12}} The Howling Griffons were annihilated; after the [[Executioners]] withdrawal, the casualty rate was more than 70%, including the catastrophic loss of their strike cruiser, ''[[Augeias]]'', and [[Chaplain Dreadnought]] [[Armand Titus|Titus]]. Despite these losses, the remaining force continued to fight wherever they could until officially relieved in 909.[[M41]]{{Fn|7b}} The Howling Griffons made use of Insurgency Forces (five Marines, one armed with a sniper rifle.) and at least one [[Callidus Assassin]] during the war.{{Fn|35}}

*'''939.[[M41]]:''' [[Hive Fleet Leviathan|Leviathan Maimed]] — [[Battle Barges]] from the Howling Griffons and [[Aurora Chapter]] under the command of [[Chaplain]] [[Cassius]] onboard the [[Ultramarines]] [[Strike Cruiser]] ''[[Vengeance of Macragge]]'' track a tendril of [[Hive Fleet]] [[Leviathan]]. As the tendril passes an [[asteroid belt]] near the [[Jomm System]], they destroy the moon of [[Vendorak]]. The resulting shockwave causes asteroids to crash into the planet, depleting the hive fleet so it can't reach the planets of Jomm.{{Fn|48}}

*'''951.[[M41]]:''' The [[Amar (World)|Amar]] secession was brought to a swift end by the rapid strikes of the Howling Griffons.{{Fn|6b}} The Howling Griffons' tactical use of [[Land Speeder Storm]]s allowed them to take the outer bastion of the Regent's palace and use his artillery against the inner palace.{{Fn|6c}}

*'''978.[[M41]]:'''{{Fn|14a}} [[War for Bhorc Prime]] (Scrap at da Scrap Yard) — A contingent of Howling Griffons was dispatched to prevent the [[Ork]]s from building bigger and better idols. They managed to seize the high ground, and, with commanding fire positions, they could press their attack on the Warlord's [[Gargant]]t fields and slow the invasion.{{Fn|14b}}
