The Roman History · Amm. 24.1.11

The next day another disaster took place; a whirlwind arose, and made havoc in many places, throwing down many buildings, tearing in pieces the tents, and throwing the soldiers on their backs or on their faces, the violence of the wind overpowering their steadiness of foot. And the same day another equally perilous occurrence took place. For the river suddenly overflowed its banks, and some of the ships laden with provisions were wrecked, the piers and dams which had been constructed of stone to check and repress the waters being swept away; and whether that was done by treachery or through the weight of the waters could not be known.
