During the [[Battle for Macragge]], Cassius fought by the side of [[Chapter Master]] [[Marneus Calgar]], to repel [[Hive Fleet Behemoth]]. During the last stages of the Battle, he accompanied the relief force that rushed to the polar fortresses to relieve the embattled [[First Company]], though it was already too late for these veterans. Few members of Cassius's unit survived the brutal close-quarters combat that followed, and Cassius himself was incapacitated by a rampaging [[Carnifex]]. He survived by only the slimmest of margins, clinging to life until the [[Apothecaries]] could tend to his ruined body, which was extensively rebuilt with [[bionic]] parts.{{Fn|3}}

After the [[Tyranid]] invasion had been repulsed, Cassius withdrew the [[Banner of Macragge]] and only allowed it back onto the field after the Ultramarines' strength had been fully restored to their former numbers.{{Cite This}}
