Pink's War: The first Royal Air Force operation conducted independently of the British Army or Royal Navy begins.

Pink's War was an air-to-ground bombardment and strafing campaign carried out by the Royal Air Force, under the command of Wing Commander Richard Pink, against the mountain strongholds of Mahsud tribesmen in South Waziristan in March and April 1925. It was the first independent action by the RAF, and remains the only campaign named after an RAF officer.
