Judges 20:34 (KJV)

And the children of Benjamin said, They are smitten down before us, as at the first. But the children of Israel said, Let us flee, and draw them from the city unto the highways.

And all the men of Israel rose up out of their place, and put themselves in array at Baal–tamar: and the liers in wait of Israel came forth out of their places, even out of the meadows of Gibeah.

And there came against Gibeah ten thousand chosen men out of all Israel, and the battle was sore: but they knew not that evil was near them.

And the Lord smote Benjamin before Israel: and the children of Israel destroyed of the Benjamites that day twenty and five thousand and an hundred men: all these drew the sword.

So the children of Benjamin saw that they were smitten: for the men of Israel gave place to the Benjamites, because they trusted unto the liers in wait which they had set beside Gibeah.
