Fall of the Wall
Currently, Sam is checking the structure of the wall.
Even though they constantly repaired it, he knew that it is only a temporary measure. Sam didn't even expect it to last two months, most of it is due to their counter-attack with the Crossbows, which made it easy for the wall to last.
In these three months, there are many surprise attacks and unconventional attacks from the opponents, the troops increased several times. They are in an extremely delicate balance. Once the wall is destroyed, they will be done for.
Sam even saw the increase in the number of vampires on the other side. So, the most defensive they could get, the more beneficial it is to them.
Sam created many defensive measures in these three months. He took every advantage this terrain has to offer and that includes the presence of this large stream.
In fact, most of the plans made revolve around the water present here.
