Ownerless Horse on the Battlefield at Moshaisk in 1812 Albrecht Adam (1786-1862)

The picture has something of this: cavalry, mammal, seated, mare, desert, wildlife, grassland, horse, mustang, outdoors, animal, antelope, landscape, farm, livestock, two.
Perhaps it’s a painting of a horse standing in the middle of a field with other horses and a man on horseback in the background with a stormy sky.
