Each covering shield gleamed slanting to the sky,
Relentless, strong, and stubborn; underneath
Their wary shelters foined the glittering death
Of stolid steel thrust livid arm to arm:
As cloud to cloud growls up a soaring storm
Above the bleak wood and lithe lightnings work
Brave blades wild warring, in the black that lurk,
Thus fenced and thrust—one tortoise shield descends,
Leaps a fierce sword shrill,—like a flame which sends
A long fang heavenward,—for a crushing stroke;
