Dymer by C.S. Lewis

Then the rain; Twelve miles of downward water like one dart, And in one leap were launched along the plain, To break the budding flower and flood the grain, And keep with dripping sound an undersong Amid the wheeling thunder all might long.

Like summer grass he drooped, Amazed, while sheeted lightning large and blue Blinked wide and pricked and quivering eyeball through. Then, scrambling to his feet, with downward head He fought into the tempest as chance led.
