The Cavalry Retreat Wilhelm Camphausen (1818-1885)

The picture has something of this: cavalry, people, group, seated, mammal, many, group together, competition, wear, military, recreation, vehicle, transportation system, race, skirmish, cowman, man, soldier, motion.
Perhaps it’s a painting of a group of men riding on the backs of horses on a dirt road in front of a castle with a sunset in the background.
