The Battle of Hanau Horace Vernet (1789-1863)

The picture has something of this: people, group, tree, competition, landscape, many, crowd, war, soccer, flame, battle, action, man, festival, military, outdoors, vehicle, smoke, park, drag race.
Perhaps it’s a painting of a military scene with a large group of people in the foreground and onlookers at the far end of the scene.
