That's a bit light on details. Here's an account by king Sennacherib:

> I destroyed the city and its houses, from foundation to parapet; I devastated and burned them. I razed the brick and earthenwork of the outer and inner wall of the city, of the temples, and of the ziggurat; and I dumped these into the Araḫtu canal. I dug canals through the midst of that city, I overwhelmed it with water, I made its very foundations disappear, and I destroyed it more completely than a devastating flood. So that it might be impossible in future days to recognize the site of that city and its temples, I utterly dissolved it with water and made it like inundated land.

However since he was punishing Babylon for rebelling one time too many, he had reason to exaggerate.
