Temptation of St. Anthony, central panel of the triptych Hieronymus Bosch (1450-1516)

The picture has something of this: people, group, many, war, man, military, woman, skirmish, child, battle, vehicle, wear, weapon, force, crowd.
Perhaps it’s a painting of a group of people and animals in an open area with a castle in the background and birds flying over the top of the scene.
