MayMetMo 2020 #19: Crows for Force

The last day of the last great war of mankind saw the forces split into two solid lines of primary colors charging at one another.   World War Three, as had so often been said, was fought with weapons of unknown power and destruction.  But this was World War Four, and it was fought with sticks and stones.  Long into the night the two last armies of man fought and killed each other until the battlefield and its green and brown ground were covered in rivers of red, and pink entrails littered as far as the eye could see.  The two last armies of man fell in a tidal wave of blood and gore until both become motionless in a sea of their own dead.   It was only when a third force arrived, that they realized the error of their ways and repented.  But surrender was never an option for the Crows.
