In the middle of the night, beneath a moon veiled by drifting clouds, Duke Vardon's forces began to withdraw from the fortress they had carved out of stone and timber. They were now retreating to Ironhold.
The mana lamps were left there to make the other party think they were still within the walls.
Marquis Valeire, who was wary of a night attack, never expected the Iron Duke, who never takes a step back, to actually retreat.
So the focus was more on the Duke Vardon ambushing them rather than them leaving the battlefield entirely.
Of course, Duke Vardon's side did not retreat all at the same time. They retreated bit by bit, and before leaving, the dwarves were forced to destroy the Roaring Thunder and the Gatling guns, removing a few parts and breaking a few more so that even if the other party gets them, they will find it difficult to replicate.
