Hillegaert, Pauwels van – Prins Maurits in de Slag bij Nieuwpoort, 2 juli 1600, 1632 - 1640 Rijksmuseum: part 1

The picture has something of this: people, landscape, vehicle, many, cavalry, water, sky, group, sea, transportation system, smoke, bird, outdoors, river.
Perhaps it’s a painting of a battle with a large group of people in the foreground and a man on a horse on the far side of the painting.
