Donggang Plantation.
The scars of battle were beginning to fade. The survivors dug out the bodies of their comrades and buried them on the small hill north of the plantation. On the street outside the barbed wire, zombies tumbled along and wandered around mindlessly.
In the days of continuous fire, Empire's sieging forces destroyed their walls multiple times and cut through the barbed wires to lure zombies into the plantation. The battle devolved into chaos between humans and zombies.
In the chaos, over one thousand slaves died.
With such a limited amount of ammunition, their ability to limit their casualties to around one thousand against an actual force showed that the slaves were certainly a force to be reckoned with.
Of course, NAC's airstrike also was part of the reason.
