The Dwarven military units have arrived, and not a moment too soon. Reports are filtering about a massive horde of -things- approaching from the north, out of the black ice. Not all of them fit the description of the strange monsters you have been encountering, either.
The Dwarves want to dig in, make a network of trenches that they can defend with Pikes, while the dwarven artillery company provides supporting fire. If they are overwhelmed, they can make an orderly retreat. Hammerers would be deployed from the flanks to force them into close combat. Dwarven crossbowmen would provide ranged support.
However, they are willing to listen to any preparation suggestions you may have in mind.
You have been granted the following units:
320 Dwarven Privates (Fighter 1. Awl Pike, Dwarven Waraxe, Light Crossbow, Half Plate, 2 Potions of Cure moderate wounds, all masterwork)
32 Dwarven Sergeants (Fighter 2, Marshal 1, Awl pike, Full plate, Dwarven Waraxe, heavy crossbow, 5 potions of Remove Disease, Magic Armour.)
16 Lieutenants (Healer 4, Light crossbow, Leather Armour, 20 Blessed Bandages, Wand of CLW, Wand of Remove Disease)
8 Captains ( Warblade 5, Dwarven waraxe, Full Plate, Heavy Steel Shield, All items Magical)
40 Hammerer Constructs (Pg 27 MM2. Does not have the unreliable trait.)
The Fist of Moradin ( 48 Experts, Profession: Siege Engineering. 4 Light Bombards, 1 Heavy Bombard)
The Dwarves have suggested you leave the fighting back of the horde to them, and that you focus your efforts on defeating any commanders or especially dangerous threats.
What do you do?
