Le sang rouge de Garibaldi Sergey Sergeyevich Solomko (1867-1928)

The picture has something of this: people, man, soldier, weapon, military, gun, war, uniform, lid, rifle, army, wear, military uniform, two, skirmish, battle, retro.
Perhaps it’s a painting of a man holding a rifle in front of another man with a gun in one hand and another man.
