Ultramarines 121st Chapter, 1st Battalion, 1st Company: The Daughters of Guilliman

Chapter Doctrine

“Ultima Ratio Bellatricum” (The Final Argument of Queens): The 121st always strive to lead with diplomacy and negotiation, but when that breaks down, a blended doctrine of swift orbital insertion, elite jump pack shock assault, and disciplined auxiliary cordon makes for a very convincing argument.

Organization of the Chapter and Allied Imperial Navy Fleet and Forces

The 121st Chapter, or “Daughters of Guilliman” consists of ten Companies split across two Battalions. My army is represented by the Ultramarines 121st Chapter, 1st Battalion, 1st Company. Each Company is about 100 Legionaries, and the 121st Chapter totals around 1,000 Astartes.

The 1st, 2nd, and 3rd Companies are housed on the Astartes Battle Barge Domina Ignis (The Lady of Fire) which is part of the 121st Chapter fleet, the “Ignis Spearhead.” Also part of the fleet is the Strike Cruiser Furiosa Princepa (The Furious Princess), which houses the 4th and 5th Companies of the Daughters, and three Nova Frigates, the Octavo Noctum (The Eight Night), the Sol Aeternus (The Eternal Sun), and the Gladius Ferrum (The Iron Sword).

They are complemented by an Imperial Navy fleet including the Lunar-class Cruiser Argentum Regina (The Silver Queen), a Dauntless-class Cruiser Contumax Filia (Defiant Daughter), and three Cobra Rapid Strike Vessels, the Pugnus Aurorae (The Fist of Dawn), the Fortis Custos (Brave Guardian), and the Lamina Vindictae (The Blade’s Vengeance). This fleet is the Talassar 2nd Fleet, which houses the 367th Ultramar Auxilia Cohort (my army will be the 4th Sub-Cohort) as well as two Questoris Knights and four Armiger Warglaives from the “Lions of Redwyn” of House Terryn.

These two fleets combined make up Battlegroup U121.SA367 or less formally, the Ignis Battlegroup.

Chapter History

• The 121st participated in the pacification campaign of the Ophidian Halo’s fringe systems. This cemented their reputation for exacting compliance missions with low collateral damage and their favor of missiles as a primary weapon for heavy support due to their tactical flexibility. They make heavy use of jump pack-equipped marines for rapid, decisive strikes, often deploying directly from Thunderhawks high in the atmosphere.
• The Thoas Insurrection began when a planet, that was once in compliance, turned the planet’s defense grid against the Imperium. Communications went dark. Then-Centurion Presca led her squad in a void-drop without waiting for orders, boarding the orbital bastion station with no additional support. Three days later, she and what remained of her squad emerged wounded but victorious—having slain the leaders of the insurrection.
• The 121st lost their former Legate, Soria Meltrax, when a retaliatory missile strike during a compliance vaporized her command post during the final assault on Carthis Spire. Disorder rippled through the lines. But Centurion Presca, returning fresh from the void-drop assault on Thoas, took command without hesitation. She never raised her voice, never asked permission. Her quiet precision stabilized the front and she succeeded in driving the enemy back. By the time the campaign ended, no one questioned who would lead them next.
• When the Word Bearers’ betrayal ignited Calth, the 121st was deployed to reinforce the orbital defense grid above the hive-cities of Nemea. They arrived too late to prevent the initial bombardments but struck back hard in void assaults across the burning bastion-stations. The fighting was savage and close-quartered, a labyrinth of ruptured corridors where boarding torches and chainblades decided each deck. Over the course of five days, the 121st fought without resupply, losing squad after squad to the red-lit melee. By the time reinforcements broke through, nearly three-quarters of the Chapter’s strength had been spent in the void. What returned from Calth was not the 121st that had mustered there. They came back diminished, with many of their senior officers slain, their companies reduced to scattered survivors. In the wake of the devastation, Guilliman authorized the induction of vast numbers of new recruits, many through the accelerated Inductii process. These warriors, clad in the newly issued MKVI power armor, were tempered in the fire of the Shadow Crusade almost as soon as their armor was sealed. Through brutal wars against traitor forces that followed, the 121st’s “new blood” proved themselves again and again, rising from stopgap soldiers to full battle-sisters.
• Initially dispatched as negotiators to meet with a force of World Eaters who claimed to still be loyal to the Emperor on Tevratha IX. During the negotiations, the World Eaters betrayed the 121st and tried to assassinate Legate Presca. Fortunately, with the help of a Questoris Knight Lancer and withering lascannon fire, Presca escaped and led her forces in a brutal counter attack, with orbitally-deployed forces raining down on the retreating World Eaters, completely obliterating their forces. (This is based on a narrative match that I actually played.)
• Took place in a revenge campaign after the 47th Ultramar Auxilia Cohort was butchered by World Eaters during the collapse of Drelvian Prime’s defense grid. The Daughters responded with orbital strikes, drop pod assaults, and a relentless purge of every World Eater present. It was said the skies burned crimson for three days.
• In a purely diplomatic success, the 121st negotiated the peaceful reintegration of the Celestis Defense Fleet, a rogue flotilla turned isolationist after Horus’ betrayal and the events of Calth. It was only after Captain Junia Nova allowed herself to be taken aboard for talks—and revealed orbital targeting solutions in her final message—that the rogue admiral surrendered. The threat of total destruction, paired with disciplined poise, made for a final argument that never needed to be fired.
• On Ferric Hold, a manufactorum world under siege by both heretics and loyalist radicals, the 121st issued a single broadcast: surrender and disarm, or be deemed forfeit. When silence answered, they enacted Protocol Ultima Ratio—Assault squads severed power nodes, dreadnoughts secured heavy industry zones, and Solar Auxilia formed a cordon around fleeing insurgents. The hold, expected to hold for months, fell in under eight hours.
• In the aftermath of the Siege of Terra, the 121st is currently engaged in clearing holdouts of traitor Iron Warriors from the space between Ultramar and Olympia. Many of these Iron Warriors are deeply entrenched and difficult to displace, but with overwhelming numbers and force, the 121st is able to move quickly from one holdout to the next, redeploying nearly as soon as the previous assault has ended.
