Die Einnahme von Calais Francois-Edouard Picot

The picture has something of this: people, many, group, cavalry, military, war, man, woman, vehicle, battle, skirmish, seated, soldier, recreation, wear, weapon, transportation system, crowd.
Perhaps it’s a painting of a group of people on horses in front of a castle and a body of water with people on the other side of the water.
