CRONOS I
The battle was bloody. Human and Orc corpses littered the battlefield.
The humans were overwhelmed at every battle line. The overwhelming numerical superiority of the Orc Empire on the battlefield threatened to consume them, forcing the Federation to a desperate strategy of resistance.
The Orc species was known for its aggressiveness, and this was on full display on the battlefield. The Orcs' physical aspects and their violence terrified the human foot soldiers, who were quite physically inferior to them.
Fortunately, the humans were better-equipped with anti-personnel weapons. Otherwise, the fight would have been short indeed.
But unfortunately, the main factor keeping the humans in the fight was cruelty, rather than courage.
