The Enrollment of the Volunteers of 1792 (unfinished) Thomas Couture (1815-1879)

The picture has something of this: cavalry, people, cart, transportation system, carriage, vehicle, war, skirmish, group, wagon, man, mammal, soldier, chariot, weapon, battle.
Perhaps it’s a painting of a group of men riding on the back of a horse drawn carriage in front of a crowd of men standing on top of a hill.
