Taurel, Jacques – Entrée de l’armée française à Naples, 21 janvier 1799 Château de Versailles

The picture has something of this: people, group, smoke, many, vehicle, war, cavalry, landscape, skirmish, military, crowd, battle, interaction, watercraft.
Perhaps it’s a painting of a large group of people standing in front of a body of water with a boat in the water and a city in the background.
