The Battle of Dujaila 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 3,500 men.

Lieutenant-General Sir Fenton John Aylmer, 13th Baronet was an Anglo-Irish recipient of the Victoria Cross. He was in command of the first failed efforts to break the siege of Kut in 1916. From a military background, Aylmer was commissioned into the Indian Army, and immediately involved in fierce fighting on the north-west frontier. In a singularly heroic action, still in his twenties, he helped rescue Townshend's garrison at Chitral, spearheading the relief column. For his valorous conduct he was awarded the Victoria Cross, and rapid promotion through the officer class.
