The front line at Mt. Dashi was not where the front was. To be precise, it was north of the front line at Mt. Dashi that the Pyro Company would soon engage in total war with the northern tribe.
There was a mountain path that lay within Mt. Dashi that acted as the Pyro Company's supply line to the north, which was also known as the lifeline.
As the main forces of the Pyro Company were deployed to the North a little late, the northern defensive line was established in a hurry. No one knew when an enemy force of nearly a 1,000 troops had infiltrated.
The barbarians from the North had been hiding in Mt. Dashi for several days already. It wasn't until the main forces of the Pyro Company started deploying north that they began intercepting the Pyro Company troops in the mountains and hindering the transportation of their supplies.
It was these nearly a 1,000 barbarians that made the Pyro Company suffer heavy casualties here.
