Alone on this battlefield, I am using up energy by constantly changing sides. I fight awhile on one side and then race across to engage in combat over there. I pause only to bind up wounds and take a short rest.
Everyone who was watching from the sidelines has moved out of range, into the growing shadows, beyond the hill.
The sun is setting. I am alone. I am scared.
I have no way of knowing where the carnage will occur next. I do not know who will get hurt or how bad their injuries will be. The observers have become bored and gone home. Combatants die on battlefields; no one misses them.
How long can I run back and forth between opposing trenches? How long can I wage war on both sides? How long is too long?
