Shower of Frogs -- what's up with the frogs?

A SHOWER OF FROGS: A WORLD WAR II MEMOIR

As we were driving back from Kairouan one afternoon, a dark cloud came over the camp and it rained water and hundreds of tadpoles, which squirmed around on the hood and floor of my jeep. We thought it very odd, being pelted by small living forms from the sky, each about half the size of the head of a pencil. By then we were so used to the strange sights of Tunisia that only later, when my honesty was questioned, when it was thought that there was upon me "the spell of Arabia" or that I had a Moses complex, only then did I search for the scientific explanation for this "plague" of frogs. Water, in being blown up from the ponds, also sucked the infinitely small tadpole. Fierce winds, common in Tunisia, blew both water and tadpoles some distance and eventually dropped the living matter with the rain. – page 29
