Man, Gotrek and Felix have spoiled me for other battle descriptions. You get the personal scale of two guys trying not to die in the absolute chaos, and then the narration pulls back and you see the whole battlefield as this horrific machine. William King’s stuff in the early books, like 'Trollslayer' and 'Skavenslayer', does it perfectly. It’s not just 'the Empire held the line'—it’s the stink of wet wool and blood, the way formations buckle when a troll rampages through, the sheer exhaustion after.
For a completely different, top-down grand strategy feel, I keep going back to 'The Empire' omnibus, especially the Heldenhammer bits by Graham McNeill. It feels like reading a tapestry of war, where the movement of whole armies matters as much as any single sword swing. It lacks the grimy immediacy of a front-line view, but it makes the battles feel colossal, like history in the making.
Honestly, some of the End Times books, for all their narrative flaws, delivered on sheer spectacle. The fall of Altdorf in 'The Fall of Altdorf' is just unrelenting. You need both kinds, I think—the visceral and the strategic—to really get that epic feel.
