A chestnut horse in a landscape Horace Vernet (1789-1863)

The picture has something of this: cavalry, horse, mare, mammal, farm, seated, animal, stable, people, racehorse, equestrian, equine, mustang, stallion, two, livestock, saddle, portrait.
Perhaps it’s a painting of a brown horse standing in front of a building with a white stripe on it’s chest and a black bridle on it’s neck.
