The rush to defend comes too late (Nahum 2:5). The defenses are already breached.
Nineveh had a reservoir created by a double dam on the Khosr River, a tributary of the Tigris that flowed through the city. The reservoir was enhanced by a series of flood gates.
The Greek historian Diodorus reported that a great amount of rain had already swollen the city’s river system. By first closing, then opening the flood gates, Nineveh’s attackers released the stored water as a battering ram against the city walls.

Isaiah 45:1–2
This is what the LORD says to Cyrus His anointed, whose right hand I have grasped to subdue nations before him, to disarm kings, to open the doors before him, so that the gates will not be shut:
2 Peter 3:10–11
But the Day of the Lord will come like a thief. The heavens will disappear with a roar, the elements will be destroyed by fire, and the earth and its works will be laid bare.
