Overwatch
Suddenly, a loud horn blows out over the sounds of fray. It sounds three times, and the elves begin to retreat back into the fort as the humans cheer over another victory, still slaughtering stragglers. A final volley of cannon fire and arrows fly high from the towers of Overwatch, signalling the surrender of the field. For now. The humans themselves retreat back their camps to avoid the incoming onslaught of missile fire and rest sore bodies and wounded.
Even as they egress from the battlefield, soldiers still remain... Lifeless icons of the tragedies of war.
