When they are attacked by Italian airplanes, they manage to shoot one down, but it crashes on one of their vehicles, killing eight men. Later, Kelly leads the six survivors on an attack of an Italian armored car but is seriously wounded. He orders Spence to leave him behind; when Spence refuses to obey, he shoots himself.
