No tactics sent in by Arky? o_O
I think Jerot's decision to rush the Knights in was too rash. The Waltar (being a large target and a chariot) has "SHOOT ME! SHOOT ME!" written all over it if you happen to be a Bolt Thrower with +1S. Even with the ward save, I'm not convinced it'll last the turn.
The Knights will bounce off the infantry, leaving the Greatswords a bit outnumbered in a war of attrition. The State Troops won't like the Grudge Thrower or the Organ Gun looking right at them, and the Anvil can sit back and fight the Artillery battle (picking off crews... eventually), especially with the BSB minimising Cannon casualties, before the combat ensues in which the Empire will be too depleted to win by attrition.
Dwarfs win.
For reference purposes, the Anvil requires no LoS, has infinite range, and can't be dispelled. Yes, I think it's cheesy too, as do 90% of all gamers
