What the 1st Warband did when the road column's center rotated away from it was the thing that Arka'garr had been building his formation toward since the moment the rotating assault began.
The rotation was the point.
The 1st Warband had not been pressing the road column's front because it expected to break through a six-thousand-man column with a thousand warriors at the front of a rotating formation.
It had been pressing the front because a force engaged at its front and disrupted at its flank experienced the two pressures as simultaneous demands on its command structure, and a command structure managing simultaneous demands made decisions in the compressed timelines of simultaneous demands rather than the considered timelines of sequential analysis.
The decisions made in compressed timelines were not always wrong but they were always reactive, and a reactive command structure was responding to the Horde's initiative rather than exercising its own.
