Tazhav Strikes Bahram from Behind

From B12.24, Tazhav Slays Bahram. It illustrates B12.24.50–56:

B12.24.50
The warriors closed round him for the fight,While foremost chiefs pressed inward in their might.
B12.24.51
The hero strung his bow and loosed his hail,Till arrows dimmed the heavens in their trail.
B12.24.52
When arrows failed, his spear rose to the sky;A sea of blood spread mountain, plain nearby.
B12.24.53
When his spear broke, he seized both gorz and sword;Blood splashed toward the dark cloud as he warred.
B12.24.54
The fight continued thus; brave Bahram bledFrom shafts that struck his limbs, his breast, his head.
B12.24.55
When strength and vigor failed him in the fight,Tazhav struck from behind with all his might.
B12.24.56
His sword struck hard upon the shoulder’s crown;Face-first from off the mound came Bahram down.
