Ultramar Campaign - Battle for Macragge: Four solar days and nights after his coronation as the Lord of Ultramar, Roboute Guilliman emerged from seclusion. In his absence, Marneus Calgar had continued to lead the fight, ignoring his injuries as he coordinated the Ultramarines' war effort. Now, though, Calgar willingly ceded control of the campaign to his gene-sire. Recognising the vastly capable Chapter Master for the asset he was, Guilliman kept Calgar close at hand in the battles that followed, and asked his counsel constantly. Brother-Librarian Tigurius, too, swiftly became a trusted advisor, the Primarch accepting that in this darker age, the trappings and powers of the Librarius had -- by necessity -- also become darker. In a move that surprised many, Guilliman also included Voldus, Cawl, Saint Celestine and Inquisitor Greyfax amongst his coterie of lieutenants. The Primarch sought the insights of every arm of the Imperial war machine, recognising that in unity lay strength.With his advisors at his side, and the unbowed might of the Ultramarines at his disposal, Guilliman began the reconquest of his homeworld. Wider galactic matters would have to wait; Macragge was still beset from every side, and if the Chapter planet fell, then even the resurrected Primarch would surely be dragged down by the tide of foes.The war for Macragge lasted a little over a solar month, and its pace was blistering. Roboute Guilliman was a force of nature, an unstoppable avatar of the Emperor's will who drove his enemies before him like cattle. First came a series of lightning-fast offensives to clear the Valley of Laponis and the partially ruined city of Magna Civitas. Batteries of Iron Warriors siege guns were overrun. The semi-sentient artillery engines were blown apart by Melta charges, their whip-fisted overseers executed with swift efficiency. Chanting masses of Chaos Cultists were surrounded inside gilded domes and soaring habblocks, before being systematically cut apart. Agemman, Celestine and Greyfax led pinpoint strikes to take back the city's primary orbital batteries. Soon enough, ruby columns of light were spearing up into the heavens to drive the Chaos warships out of their geosynchronous orbits above the Ultramarines' fortress-monastery.This was only the beginning. Led by the famed tank commander Antaro Chronus, roaring columns of Ultramarines armour swept the Traitor battle groups from the Magletine Highlands, and drove their survivors into the storm-tossed Pharamis Ocean. Grand Master Voldus and his 3rd Brotherhood of the Grey Knights lent their might to the reconquest when they spearheaded the strike against the corrupted city of Collosae. Here the silver-armoured Daemon Hunters fought a cat-and-mouse battle with cruel bands of Night Lords, who had veiled the city in an unnatural gloom. The Traitors were eventually driven out, and a mysterious blood ritual halted before it could come to fruition, though the entire city had subsequently to be levelled from orbit for fear of its Chaos taint.Guilliman led attacks against Valmari, Mount Tarphus and the snowy Gallinus Pass, emerging triumphant at every turn. The Ultramarines swept all before them, combining their exceptional skill and discipline with the visionary battle plans of their Primarch into an unstoppable whole. The Ultramar Defence Auxilia followed up each new conquest, digging in and fortifying in great number so that any attempts by the Forces of Chaos to counterattack were met by overwhelming resistance. Though the Heretic Astartes fought furiously, and inflicted sore losses upon the Loyalists, they simply could not match the strategic acumen of Roboute Guilliman, and one Chaos warband after another was defeated. Even those who fled Macragge found no haven in the void, for their invasion craft had been surrounded and reduced to burning scrap by the Ultramar Defence Fleet.Finally, after long solar weeks of vicious battle and a vast toll of the dead, the world of Macragge was liberated once more.
