Odevaere, Joseph Denis – De laatste verdedigers van Missolonghi, 22 april 1826, episode uit de Griekse vrijheidsoorlog, 1826 Rijksmuseum: part 2

The picture has something of this: people, wear, group, woman, veil, child, man, military, many, outfit, lid, son, war, royalty, weapon.
Perhaps it’s a painting of a group of men standing next to each other in front of a building with a cross on the top of one of the men’s head.
