The Battle of Dujaila (Turkish: Sâbis Muharebesi) was fought on 8 March 1916, between British and Ottoman forces during the First World War. The Ottoman forces, led by Colmar Freiherr von der Goltz were besieging Kut, when the Anglo-Indian relief force, led by Lieutenant-General Fenton Aylmer, attempted to relieve the city. The attempt failed, and Aylmer lost 4,000 men.
