The counterweight boxes of more than a dozen trebuchets dropped at once. Their enormous arms snapped upward, hurling over a dozen boulders, each half the size of a grown adult and hewn into sharp-edged shapes, high into the air!
The boulders traced deadly arcs through the poisonous fog, whistling through the air before striking the fortress's outer wall with deadly precision.
Boom! Rumble-!
The earth shook!
The walls Karag took such pride in groaned beneath the most primitive of kinetic assaults. Huge craters were smashed into the hard stone, while pallid bones shattered outright into powder. The tremendous impacts sent the xenos guards tumbling from the battlements in a screaming cascade.
"Keep going! Don't stop! Smash that shell they're so proud of!" Mortarion roared.
The second and third volleys of boulders followed in quick succession. The old doctor's trajectory calculations were exceptionally precise, concentrating almost every boulder on a stretch of wall roughly twenty meters wide.
At last, after the fourth volley, the battered section of wall could hold no longer. With a deafening crash, it collapsed into a ruined slope of rubble.
The fortress had been breached.
"Brothers! Follow me!"
Mortarion gave the xenos no chance to catch their breath. Leading the charge, his massive body became a streak of pale lightning as he raced over the collapsed wall and plunged straight into the fortress!
Behind him, thousands of elite human soldiers wearing gas masks surged through the breach like a black flood bursting its banks, unleashing roars that had been suppressed for countless generations!
It was a one-sided slaughter whose outcome was never in doubt.
Facing the pale reaper who swung his enormous War Scythe as though nothing could stand in his way, and humans who no longer feared the poisonous fog, who fought without fear of death
