Hendrick Verschuring – Cavalry attacking a Fortified Place Part 3 National Gallery UK

The picture has something of this: people, vehicle, skirmish, military, battle, group, army, war, soldier, weapon, battlefield, many, transportation system, seated, cavalry, wear, man.
Perhaps it’s a painting of a battle with a man on a horse in the foreground and a group of men on horseback in the middle of the background.
