Portrait of Marshal Michel Ney (1769-1815) Commander of the Rear Guard, during the Retreat from Russia, November 1812 Jean Charles Langlois (1789-1870)

The picture has something of this: people, wear, man, lid, winter, veil, woman, snow, weapon, two, portrait, outfit, costume, outerwear, cold, scarf, war.
Perhaps it’s a painting of a man in a military uniform standing in the snow with a horse and a man in a horse drawn sleigh behind him.
