Lingelbach, Johannes – Het vertrek van Karel II van Engeland, uit Scheveningen, 2 juni 1660, 1660 - 1674 Rijksmuseum: part 1

The picture has something of this: people, group, cavalry, many, mammal, landscape, seated, vehicle, man, army, transportation system, daylight, military, mountain, crowd, soldier, weapon, recreation.
Perhaps it’s a painting of a group of people riding horses on a beach next to a body of water with boats in the water and people standing on the beach.
