Soldier On Horseback Josep Cusachs i Cusachs (1851-1908)

The picture has something of this: cavalry, military, army, seated, soldier, battlefield, people, weapon, war, skirmish, gun, man, equestrian, group, mammal, uniform, rifle, many, sword, rider.
Perhaps it’s a painting of a group of men riding on the backs of horses in a field with other men on horseback in the distance, with a cloudy sky in the background.
