The Entry of Napoleon Bonaparte (1769-1821) and the French Army into Munich, 24th October 1805 Nicolas Antoine Taunay (1755-1830)

The picture has something of this: people, group, many, vehicle, daylight, man, crowd, festival, cavalry, road, mammal, tree, group together, seated, wear, military, transportation system, army.
Perhaps it’s a painting of a large group of people in a wooded area with a castle in the background and a man on a horse in the foreground.
