—Book's tag-line

Tallarn is the forty-fifth volume in the Horus Heresy series of novels and is an anthology. Tallarn was released in July 2017 as a hardback which includes a full-art hardcover. Tallarn gathers all of the short stories and novellas of John French that deal with the Battle of Tallarn.


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 out 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 standard 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.


Tallarn contains the following 2 short stories, and 2 novellas:
