At first, it might have just been an instinctive dodge.
Facing a behemoth far greater in size than themselves, humans' innate reaction is to evade, all the more so when there's an even more dangerous, howling, slaughtering humanoid beast on the back of the beast.
However, the individual's instinctual evasion soon led to the disintegration of the troop's formation.
The ferocious warriors who leaped over the trenches discarded their broken spears and drew their swords to hack wildly, while the surrounding militia dropped their weapons and retreated in a rolling scramble.
The "Young Soldiers" were originally the most fragile part of this army.
The "Mature Soldiers" had at least undergone the baptism of the Battle of Panto River; the young soldiers were thoroughly civilians, having only received the simplest training.
Young soldiers could also form a seemingly impregnable battle line, allowing the use of long-range weapons such as crossbows and muskets.
