Saturnino (Warhammer The Horus Heresy: Siege of Terra, 4)

The Traitor Host of Horus Lupercal tightens its grip on the Palace of Terra, and the walls and bastions begin to crumble and fall one by one. Although Rogal Dorn, the Praetorian of Terra, redoubles his efforts to hold back his relentless enemies, they outnumber and outgun him. Dorn cannot defend everything at once. Any chance of survival demands some sacrifice, but which battles can he afford to lose in order to win others? Is there a strategy, a crucial battle, that can turn the tide of the war once and for all and secure victory?
