Vostroyan Firstborn - Notable Campaigns: Defence of Nimbosa (790.M41) - The 9th Vostroyan Regiment, "The Old Irascibles," defended the Imperial world of Nimbosa against the T'au Empire's effort to expand their burgeoning alien empire and annex the world. The Vostroyan regiment heroically sacrificed themselves to a man defending the factory city of Polia against the T'au Commander Brightsword. Inspired by the Vostroyans' sacrifice, the populace refused to submit to the T'au Empire and its Greater Good.Spinward Front Crusade (814.M41) - The 55th Vostroyan Firstborn Regiment is currently involved in the ongoing Imperial Crusade in the Spinward Front of the Calixis Sector. They are currently deployed to the capital world of Kulth and continue to fight an ongoing campaign against the Ork forces of WAAAGH! Grimtoof and the Secessionist forces of the Severan Dominate.Kieldar Rebellion (956.M41) - The Kieldar Rebellion is utterly crushed by the combined forces of the Vostroyan, Cadian, Mordian, Loriar, Elysian, Catachan, Aegis, Tallarn, Harakoni, Neocassan, Paragon, Birmingham, Morax, Jjojos, Pintax, Athanos, K'phrani and Rassiosan Imperial Guard regiments.Disappearance of Grand-Marshal Durov (997.M41) - Grand Marshal Durov of Vostroya reports Daemonic incursions in the Finial Sector. Contact with Durov's Army Group was lost, and its whereabouts remain unknown.Fall of Karak Prime (998.M41) - Reformed after their destruction on Nimbosa, the 9th Vostroyan Regiment once again met their ultimate fate during the Fall of Karak Prime in 998.M41. They held the hive city that served as the planetary capital for eighteen standard months against the brutal onslaught of a splinter Tyranid fleet of Hive Fleet Moloch, valiantly facing the Tyranid swarm that stretched from the base of the city's walls to the distant horizon. With the onset of midwinter, and with the rapid depletion of ammunition and supplies, the 9th Vostroyan knew that they were doomed and vowed to sell their lives dearly. Only when the bulk of the Tyranid swarm had passed into the city did the regiment detonate its nucleonic stack, incinerating the hive, its defenders and an estimated 85% of the Tyranid swarm. With the coming of midwinter, the few surviving Tyranid organisms eventually starved to death and the splinter Hive Fleet was entirely defeated.Fall of Medusa V (999.M41) - The Imperial Mining World of Medusa V, located in the Ultima Segmentum, was devoured by a massive Warp Storm in 999.M41. Fortunately, the military forces of the Imperium of Man were able to evacuate the entire surviving civilian population of the planet before it was consumed. Before completing this evacuation, the world became the centre of a large military conflict between eight of the Milky Way Galaxy's major powers for control of the world, each for its own reasons in a campaign later known to Imperial savants as the Fall of Medusa V. Multiple Vostroyan Firstborn regiments, which included the 5th, 7th, 11th, 16th and 241st, answered the call to arms, and fought in the Medusa V campaign.Gates of Balcarhsa (3789.999.M41) - Lord Marshal Graf Harazahn of Vostroya rallies the forces of the Imperial Guard and assumes overall command of the Army Group deployed to Medusa V. The Lord Marshal's forces defeat the Eldar at the Gates of Balcarhsa.Liberation of Kurkaris (Unknown Date.M41) - The 22nd Vostroyan Firstborn Regiment was instrumental in the liberation of the world of Kurkaris. The 22nd is notable for being one of the very few Vostroyan regiments to make use of Rough Riders mounted cavalry squadrons (called Hussars by the Vostroyans) in order to better engage the Orks in Kurkaris' thick forests.Defence of Danik's World (Unknown Date.M41) - The 68th Vostroyan Firstborn Regiment defended Danik's World from a massive Ork invasion and a planet-wide rebellion. Last known Imperial records of the regiment indicated that it had dropped to a strength of around 30 effective soldiers, all from the 5th Company. The bulk of the regiment was destroyed by the rebellious forces, both through sedition and ambush tactics. The 5th Company, which had previously been attached as a rearguard, suffered severely in their valiant attempt to make it back to Imperial lines. The commander of the 5th Company, Captain Gregorious Sebastev, was officially placed in command of the hardened survivors, shortly before the whole group was seconded to the Inquisition. The eventual fate of these survivors, and therefore the regiment itself, is currently unknown.
