Tristan knew that people's hearts had scattered.
Unlike the Resistance Army they faced, Ireya and her companions fought for their homeland, to protect their own territories and loved ones. They all shared a common belief, hence they fought more fiercely as the battle went on, seemingly tireless.
On the other hand, although they had an absolute advantage in numbers, they came from different places and had no particular reason to capture the western regions.
It was fine when they were winning, as there was money to be made and everyone would fight hard. But once trouble started, problems emerged easily, and they could even crumble and fall apart.
While Tristan was still reflecting on this, he saw that the dwarves on the other side had already seen the bad turn of events and had taken off first.
Their commander Balin had been taken out early on, and since they were at the forefront, they took the heaviest hits, already losing two to three thousand men.
