Perhaps the reality is just as Glolov said, no one knows why this corner holds any significant meaning, but since the battle is intensifying, let's just send more troops.
An insignificant corner, taken at the cost of countless lives, still appears to serve no purpose, so the battle over this corner seems rather meaningless. However, even if this place is of no use to us, what if it's useful to the enemy? Since the enemy is reinforcing here, we need to reinforce as well. The continued reinforcement by the enemy signifies the importance they place on this area. No matter what, continue to send more troops, defeat the enemy, and thwart their objectives.
War is filled with uncertainties. Sometimes, a battle that escalates in scale and casualties unfolds in a confusing manner. As for when it will end, only when one side achieves complete victory or can no longer continue and withdraws will it conclude.
