I'll need to wait and find out how much manpower DiabloDude is putting to this.
But in the very least there will be no open windows on the western end of this castle for sure. Closed and barred, nailed if they have to be.
Most guards I'd say will end up stationed at T1, 1, T2, 3 and the front gate. Probably have resting guards take up in the Grand Hall for fast reactions if needed. I imagine I'll have a perimeter in the courtyard surrounding the main tower.
Open to suggestions of course,
