Chapter 55: Excavation
The rivers across the Great Wilderness all belong to dendritic drainage systems, with tributaries and the main rivers intersecting at sharp angles.
The Herders, taking advantage of the terrain, built their city on the narrow high ground where two rivers met. The city was surrounded by water on three sides, making it easy to defend and hard to attack; only the northwest side was solid ground.
Although the two unnamed rivers were rapid, they were not too wide, allowing for swimming or boating to cross. The land around Bianli City was thus split into three parts by the two rivers.
Therefore, the besieging Paratu army also split into three, with two flanking forces encamped on the south and northeast sides, across the river, to prevent the Herders inside the city from fleeing across the river.
