Destruction of The Ironclad

The Destruction of The Ironclad was a brutal exterminatus campaign conducted by the Corrosive Thorns Space Marine Chapter against the Renegade Ironclad Chapter in 511.M38.

History
The first ever elimination of a Chapter by the Corrosive Thorns was the case of the Ironclad, an Iron Hands Successor Chapter of an Unknown Founding. The rogue Chapter had dedicated themselves to a Mechanical God from an unknown civilisation, an unforgivable heresy that required a decisive response. The High Lords of Terra tasked the Corrosive Thorns Chapter to put down these rogue Astartes. The Corrosive Thorns took the Ironclad by surprise upon their homeworld using their trademarked 'Steel Rain' tactic, crushing multiple Astartes who were outside patrolling around the Fortress-Monastery. The Chapter moved quickly cutting through the guards straight into the relic room and taking all the rouge chapter's relics and unique gear while the majority of the assaulting forces took down high ranking Astartes before killing the lower-tiered ranks. After successfully eliminating the Ironclad the Chapter were much lauded and held in high esteem by the High Lords as the likes of the ruthless Minotaurs Chapter, and forevermore, would called upon the Corrosive Thorns to deal with a Chapter that had fallen from the Emperor's light.
