Foruhil's Arrow Fells Horse and Rider

From C3.32, Foruhil Battles Zangula. It illustrates C3.32.3–6:

C3.32.3
The grim-faced Turk, far off, came into sight;He strung his bow and drew the bowstring tight.
C3.32.4
He showered shafts on Zangula with skill,And pressed from every side against him still.
C3.32.5
One arrow struck the horse with all its might;It pierced both horse and rider in its flight;
C3.32.6
The fleet steed crashed down headlong in the fight,And pale Zangula tumbled from its height.
