Pieneman, Jan Willem – De slag bij Waterloo, 1824 Rijksmuseum: part 1

The picture has something of this: people, group, man, cavalry, woman, wear, many, weapon, military, veil, war, skirmish, soldier, child, lid.
Perhaps it’s a painting of a man riding on the back of a brown horse in front of a group of men in military garb and holding a sword.
