Return to Shiganshina arc
Dirk attended a meeting with Erwin Smith and the rest of the Survey Corps' Squad Leaders to discuss the recent revelations about Eren's father Grisha Yeager.

Dirk participated in the Survey Corps' mission to retake Wall Maria, and after the emergence of the Beast Titan and his forces, Dirk's squad was ordered by Erwin to regroup with Squads Dirk and Klaus to guard the Corps' horses. He and his fellow soldiers fought off nearby Titans to protect the recruits in Dirk's squad while they moved the Corps' horse to a safe place. During the fighting, however, Dirk and his fellow soldiers were killed by the Beast Titan when he started throwing crushed boulders at them, cutting them all to pieces.
