The Caravan Józef Brandt (1841-1915)

The picture has something of this: people, soldier, mammal, man, war, military, cavalry, group, army, weapon, skirmish, vehicle, transportation system, gun, battle, desert, water, seated, rifle.
Perhaps it’s a painting of a group of men riding horses on a dirt field next to a body of water with a sky in the background and clouds.
