But no morrow was to break on the great mass of those who took their rest in the tents of the Assyrians.

The divine fiat had gone forth.

In the night, as they slept, destruction fell upon them.

"The angel of the Lord went out, and smote in the camp of the Assyrians an hundred fourscore and five thousand; and when they arose early in the morning, behold, they were all dead corpses." A miracle, like the destruction of the first-born, had been wrought, but this time on the enemies of the Egyptians, who naturally ascribed their deliverance to the interposition of their own gods; and seeing the enemy in confusion and retreat, pressed hastily after him, distressed his flying columns, and cut off his stragglers.

The Assyrian king returned home to Nineveh, shorn of his glory, with the shattered remains of his great host, and cast that proud capital into a state of despair and grief, which the genius of an AEschylus might have rejoiced to depict, but which no less powerful pen could adequately portray.
It is difficult to say how soon Assyria recovered from this terrible blow.
