Tallarn — John French

The greatest tank battle in the history of the Horus Heresy!

As the Warmaster's campaign of galactic domination continues, Horus' 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.
