This was actually an Abyssals and Abyssal Dwarves vs Dwarves game.
The combined A&AD forces let the Dwarves come to them and a number of combats took place midfield towards the end of the game. The left flank of the Dwarves proved too strong for the A&AD to hold back, although the A&AD fared better on the right.
The Angkor Heavy mortar failed to land any shot on the intended target, but did survive to the end.
Excellent! Goooood… goooood!
Hooray for the Abyss!
