The Iron Warriors came from nowhere, falling upon the world of Tallarn in a flash and devastating it with deadly virus weapons. A verdant world was transformed in a heartbeat into a radioactive wasteland... but that was only the beginning.It's a collection of all John French's tales from Tallarn... do you really need any more convincing? Okay then. Millions of tanks clashing in desperate battle on a dying world.

As the Warmaster's campaign of galactic domination continues, his generals seek out fresh battlefields to conquer. After leaving the Crone World of Iydris behind, Perturabo strikes for Tallarn. A bitter, vengeful primarch, the lord of the Iron Warriors unleashes a deadly bombardment against the world, killing millions but entrenching the survivors. A brutal, all-consuming armoured conflict ensues, the greatest of the war, and one that grinds down all combatants over more than a year of relentless battles. But Perturabo's reasons for the attack are about more than unleashing punitive destruction against the Imperium - he has an entirely darker purpose in mind.
