Francois Josephe Kinsoen – Portrait of Charles Victor Emmanuel Leclerc, General in Chief of the Army of Saint-Domingue Château de Versailles

The picture has something of this: people, sword, wear, veil, weapon, lid, man, costume, woman, sash, war, outfit, soldier, military, portrait.
Perhaps it’s a painting of a man in a blue and white uniform with a large hat on his head and a sword in his hand, with a mountain in the background.
