The '''Battle for Columnus''' (also referred to as the '''Weirdwaaagh!''') was a campaign fought by the [[Imperium]] on the [[Forge World]] of [[Columnus]] in 260.[[M41]].{{Fn|1a}}

Shortly after the [[Slaughter on Dawnbreak|Battle on Dawnbreak]], [[Clan Raukaan]] was again tasked with leading another Iron Hands mission. This time they were to defend the [[Forge World]] of [[Columnus]] from an incoming [[Ork]] [[Waaagh!]]. A third of the Chapter's strength was ultimately deployed for the operation, with ten [[Iron Father]]s leading the expedition. Accompanying the Iron Hands were 30 [[Titan]]s from their close allies in the [[Adeptus Mechanicus]], the [[Legio Ferrax]]. They were to bolster the [[Skitarii]], [[Cataphract Class Robot]]s, and [[Imperial Guard]] forces already assembled on Columnus. The Iron Hands beat the Orks arrival to Columnus, laying out their forces in three [[Space Marine Company|Company]]-sized armies at Kemlos, Urdri, and Slartav. Surprisingly, the Marines discovered that the [[Raven Guard]] under [[Shadow Captain]] [[Stenn]] had also arrived to defend Columnus from the Greenskins, something that caused a degree of anger among the Iron Hands. Nonetheless the two forces were tacitly allies, and the Ork invasion arrived several days later.{{Fn|1a}}

Soon enough Captain Stenn was scooped up into the air by the psychic mighty of Zagdakka and ripped to pieces by telekinesis. As the last Raven Guard fell, Kristos' [[Land Raider Redeemer]]s opened fire, sending the entire breach into a flash of flame. The distracted Warpboss Zagdakka and his entire retinue were annihilated in the sudden assault. With their leader's death, the psychic discipline over the Orks crumbled. Greenskins began to retreat in confusion, freeze where they were, or attack one another. Soon enough, the surviving Imperial forces were able to massacre the Orks. Nonetheless, the method of victory by Kristos proved controversial even on [[Medusa (Planet)|Medusa]].{{Fn|1a}}

Kristos' method of victory was so controversial that the [[Iron Council]] on [[Medusa (Planet)|Medusa]] sought to launch an investigation which became known as the '''Kristosian Conclave'''. Some felt that Kristos' sacrifice of the Raven Guard on Columnus was not motivated by cold logic but rather an agenda and personal feelings. The on-and-off investigation ground on for decades and then centuries, eventually escalating from a look into Kristos' conduct into an examination of the Chapter's entire philosophy and doctrine since the [[Horus Heresy]]. Kristos and his supporters (known as '''Kristosians''') proved unapologetic despite objections from figures such as Iron Captain [[Verox]], [[Chaplain]] [[Marrus]], and the young [[Kardan Stronos]].{{Fn|1b}}

At its two hundredth year in 460.[[M41]], the Kristosian Conclave still divided the Iron Hands more than ever.{{Fn|1b}}
