The sentinel on the watchtower had seen a cavalry troop charging toward the main gate from afar.
The alarm bell rang, and the armed defenders hurriedly made their way to the battlements, while the civilians who were digging trenches outside the fortress swarmed toward the gates.
This was a small fortress standing just outside of Niutigu Valley, no more than fifty meters in length and width.
It was surrounded by two layers of earthen walls, with the main wall two meters higher than the inner one, which barely reached one meter, and there were only two gates, front and back.
For a moment, the soldiers wanted to go out, and the civilians wanted to get in, causing a blockade at the gate that was impassable.
"Where did the Herders cross the river?" Captain Thomas, frazzled and desperate, climbed the battlements and bellowed, "Don't block the gate! Let our men out first!"
The civilians were bent on seeking refuge inside the fortress and ignored him.
