Here we go then!
Turn 1:
Both sides advance, a cannonball falls short of the Chariot but manages to kill a Centigor.
Turn 2.
Some more marching and another decent hit by the cannon - this time the Gors suffer some casualties.
Turn 3.
Triple charge! The Chariot, Razorgor and Ungors try to have a go at the Halberdiers block, only to bounce back immediately (the Razorgor crucially having failed its roll). The Beastmen Shaman manages to kill some 8 Handgunners with Flock of Doom.
Turn 4.
Beastmen hordes move into position - the Gors to the flank of the advancing Halberdiers, the Bestigors right up the Greatswords. The Cannon scores a direct hit on the Shaggoth and kills is outright!
Turn 5 and 6.
The Gors butcher the Halberdiers. The Greatswords put up a fiercer fight but are, in the end, also overcome.
The result is a draw, technically: the Empire forces claiming the courtyard and wheatfield, while the Beastmen are left in control of the forest and cemetery. We can only assume the empire cavalry came round the hill immediately afterwards, because thing were sure looking bleak for the forces of men!
