Information General Desaix and the Peasant 1867 Jean-Louis Ernest Meissonier (1815-1891)

The picture has something of this: people, cavalry, mammal, group, seated, man, many, road, child, wear, herder, daylight, woman, tree, recreation, group together, motion, lid, livestock.
Perhaps it’s a painting of a group of people standing next to each other in a wooded area with a horse and a man on the far side of the painting.
