Droochsloot, Joost Cornelisz. – Het afdanken der waardgelders door prins Maurits op de Neude te Utrecht, 31 juli 1618, 1625 Rijksmuseum: part 2

The picture has something of this: cavalry, seated, people, group, many, mammal, military, man, soldier, crowd, equestrian, army, building, town, wear.
Perhaps it’s a painting of a group of people on horses in a town square with buildings and people on horseback in the foreground and a dog.
