The Battle of Romani was the last ground attack of the Central Powers on the Suez Canal at the beginning of the Sinai and Palestine campaign during the First World War. The battle was fought between 3 and 5 August 1916 near the Egyptian town of Romani and the site of ancient Pelusium on the Sinai Peninsula, east of the Suez Canal. This victory by the 52nd (Lowland) Division and the Anzac Mounted Division of the Egyptian Expeditionary Force (EEF) over a joint Ottoman and German force, which had marched across the Sinai, marked the end of the Defence of the Suez Canal campaign, also known as the Offensive zur Eroberung des Suezkanals and the İkinci Kanal Harekâtı, which had begun on 26 January 1915. This British Empire victory ensured the safety of the Suez Canal from ground attacks and ended the Central Powers' plans to disrupt traffic through the canal by gaining control of the strategically important northern approaches to it. The pursuit by the Anzac Mounted Division, which ended at Bir el Abd on 12 August, began the Sinai and Palestine Campaign. Thereafter the Anzac Mounted Division supported by the Imperial Camel Brigade were on the offensive, pursuing the German and Ottoman army many miles across the Sinai Peninsula, reversing in a most emphatic manner the defeat suffered at Katia three months earlier. From late April 1916, after a German-led Ottoman force attacked British yeomanry at Katia, British Empire forces in the region at first doubled from one brigade to two and then grew as rapidly as the developing infrastructure could support them. The construction of the railway and a water pipeline soon enabled an infantry division to join the light horse and mounted rifle brigades at Romani. During the heat of summer, regular mounted patrols and reconnaissance were carried out from their base at Romani, while the infantry constructed an extensive series of defensive redoubts. On 19 July the advance of a large German, Austrian and Ottoman force across the northern Sinai was reported.
