The painting is believed to be from the Ming Dynasty, depicting a battle scene. The people in the painting are dressed in traditional Chinese clothing and are engaged in a fierce battle, with some of them brandishing swords and shields. The river is winding its way through the landscape, with a few trees and mountains in the distance. The sky is a deep blue, with white clouds scattered throughout.
