General Nikolai Skobelev on horseback. 1883. Oil on canvas. 47h30 Nikolay Dmitriev-Orenburgsky (1837-1898)

The picture has something of this: cavalry, sword, people, man, weapon, soldier, military, skirmish, armor, helmet, knight, war, seated, wear, army, warrior.
Perhaps it’s a painting of a man riding on the back of a white horse next to another man on.
