A good bit of time has passed, and hundreds of thousands of dwarves have mustered at Av to begin the campaign against the orcs, a few thousand men not of the Tsardom who live near the dwarves have mustered to the army as well. When the Tsar's troops arrive, the march will begin. In all likelihood, most of the fighting will be underground. THe main objective of the campaign will be to drive the orcs out of several of the dwarves' ancient cities including the former capitol of the dwarves, Mt. Mithria. Since many of the mines in the mountains to the West dried up, chances are that there's little mining to be gained from the expedition, only what loot can be taken from the orcs.
