The essence of the Storm Plan boiled down to just one sentence: force the Terdun people into a battlefield where cavalry could not exert their full power.
How to accomplish this?
Winters's strategy was simple and straightforward—block all other routes.
Defense must rely on the dangers of mountains, rivers, and streams. But what to do at the Panto River, where there was no natural terrain to defend?
The only solution was to create man-made mountains and rivers.
Walls, that is, man-made mountains.
Between the two fortifications, the Shield Wall was constructed under the supervision of Bard, having broken ground concurrently with Winters's mobilization and evacuation of the lower Iron Peak County population.
The manpower Bard used came from the refugees of Blackwater Town and Wugou Town.
Conscripting refugees to build the wall was not solely to meet military needs but also a way of managing and providing relief.
