The Battle of Ayun Kara (14 November 1917), was an engagement in the Sinai and Palestine Campaign during the First World War. The battle was fought between the New Zealand Mounted Rifles Brigade and a similar sized rearguard from the Turkish 3rd Infantry Division, which was part of the XXII Corps of the Ottoman Eighth Army's 8th Army under Kress von Kressenstein. The battle started in the afternoon with the New Zealanders caught in the open. Despite Turkish artillery, machine-gun fire, and infantry assaults, the New Zealanders gradually fought their way forward.
