At the same time that the humans' major counterattack began on the western battlefront, a major change also occurred on the eastern battlefront.
Pincer attacks were quite a common war strategy. However, in order for pincer attacks to be truly effective rather than just suicidal, the most important part was timing.
Back when the western battlefront was still quiet, the eastern battlefront was already quite raucous at 3:30 in the morning, the time when people would usually be the most tired.
"It's a night ambush!"
The devils shouted a warning that echoed in the night. None of them had expected that the human alliance would ambush them at such a time in the night.
Out of all the species, humans were probably the least suited for night battles. Humans didn't have infrared heat sensing abilities like the snakemen, or night vision like the elves. Humans were basically blind without sunlight or other lighting.
