Might I suggest the attack on the Turks at Wadi Fara in Palestine.
Following the success of Allenby’s attack at Megido on the 19th of September, the Turkish divisions were forced to retreat through the narrow defile of Wadi Farra. On the 21st of September the Australians trapped them there, when they bombed the head and the tail of the Turkish column. Together with RAF SE5as and DH9s the Australians mercilessly bombed and strafed the terrified Turks.
In the words of T. E. Lawrence, "When the smoke had cleared it was seen that the organization of the enemy had melted away. They were a dispersed horde of trembling individuals, hiding for their lives in every fold of the vast hills. Nor did their commanders ever rally them again. When our cavalry entered the silent valley the next day they could count ninety guns, fifty lorries, and nearly a thousand carts abandoned with all their belongings. The RAF lost four killed. The Turks lost a corps."
