The Raid on Bir el Hassana (Hasna) occurred in the Sinai Peninsula in February 1917, during World War I. It was a minor action between an augmented battalion of the Imperial Camel Corps on the one side and a score of Turkish troops plus some armed Bedouin on the other. The raid occasioned the first aeromedical evacuation in the British Army.
