Judges 20:33-43

Then all the men of Israel got up from their places and placed themselves in battle formation at Baal-tamar; and the men of Israel [who were] in ambush rushed from their place in the plain of Maareh-geba. When the ten thousand choice [fighting] men from all Israel came against Gibeah, the battle was hard and fierce; but the Benjamites did not realize that disaster was about to strike them. And the LORD struck down [the tribe of] Benjamin before Israel, so that the sons of Israel destroyed twenty-five thousand one hundred men of Benjamin that day, all of whom were swordsmen. So the Benjamites realized that they were defeated. Then men of Israel gave ground to the Benjamites, because they relied on the men in ambush whom they had placed against Gibeah. Then the men in ambush quickly rushed and attacked Gibeah; and the men in ambush also deployed and struck the entire city with the edge of the sword. Now the appointed signal between the men of Israel and the men in ambush was that they would make a great cloud of smoke rise from the city. So the men of Israel turned in the battle, and Benjamin began to strike and kill about thirty men of Israel, for they said, “Certainly they are defeated before us as in the first battle!” But when the [signal] cloud began to rise out of the city in a column of smoke, the Benjamites looked behind them; and behold, the entire city went up in smoke to heaven. When the men of Israel turned back again, the men of Benjamin were terrified, for they saw that disaster had fallen upon them. Therefore, they turned their backs before the men of Israel [and fled] toward the direction of the wilderness, but the battle followed and overtook them. As the [fighting men of the] sons of Benjamin ran among them, the Israelites of the cities came out and destroyed them. They surrounded [the men of] Benjamin, pursued them relentlessly, and overtook them opposite Gibeah toward the east.
