The fierce battle throughout the night was a great test of the will and military strength of both sides. Both the Middle-Earth alliance and Sauron's army had suffered great losses. However, although the casualty figures of the attacking side were far higher than those of the defending side, the advantage was actually with the attacking side.
Why? Because the gap between the military forces of the two sides was simply too great. The Middle-Earth alliance only had 6000 troops, so even if the casualties of Sauron's army outnumbered the opposition's by 10 to 1, it was still not something the Middle-Earth alliance could bear. When the casualty rate of an army exceeded 40%, the army would surely collapse – and the defending army was already very close to this threshold. If it were not for Knight and the contestants fighting tooth and nail to support the defending army, they probably would have collapsed already.
