The final engagement in the Meren valley was the most complex battle the campaign had yet produced, the confluence of every tactical lesson the Horde had developed across eight weeks of continuous operations applied simultaneously in a single piece of terrain that Khao'khen had been studying since the day the column first arrived at Millbridge.
He had chosen the night engagement because darkness was the equalizer that his numerical disadvantage required. Twenty thousand soldiers in a valley at night had the same problem as four thousand soldiers in a valley at night: the road was the road, the river was the river, and the darkness did not care how many people were trying to use the road at the same time.
