Ben–Hadad heard this message while he and the kings were drinking in their tents, and he ordered his men: “Prepare to attack.” So they prepared to attack the city.<idle musing>

The junior officers under the provincial commanders marched out of the city with the army behind them and each one struck down his opponent. At that, the Arameans fled, with the Israelites in pursuit. But Ben–Hadad king of Aram escaped on horseback with some of his horsemen. The king of Israel advanced and overpowered the horses and chariots and inflicted heavy losses on the Arameans. 1 Kings 20:12–21 TNIV

So, what do you think? Am I off the wall? Just an
