Velde van de Battle Sun Adriaen van de Velde (1636-1672)

The picture has something of this: cavalry, people, transportation system, mammal, group, man, cart, seated, skirmish, desert, vehicle, weapon, herder, cattle, carriage.
Perhaps it’s a painting of a man riding on the back of a white horse next to a group of men standing on the side of a road with a flag.
