The aftermath of the first battle was quickly calculated. Every class was either happy or in despair with their own results, but totalled up, 40 were dead from all the classes and the injured numbered near a hundred. Out of the heavily-injured ones, over ten of them had lost all battle capabilities, basically making them no different from casualties of war.

That was just the first day, and because of that, the acting monitors were in a heated discussion within the headquarters. Some of them felt like the fortress was too small, and coupled with their disadvantage in numbers, they would not be able to defend for too long if they were surrounded. That was why they felt that they should begin their defense outside of the fortress--in order to delay the enemies.
