The Battle of Abu Klea, or the Battle of Abu Tulayh took place between the dates of 16 and 18 January 1885, at Abu Klea, Sudan, between the British Desert Column and Mahdist forces encamped near Abu Klea. The Desert Column, a force of approximately 1,400 soldiers, started from Korti, Sudan on 30 December 1884; the Desert Column's mission, in a joint effort titled "The Gordon Relief Expedition", was to march across the Bayuda Desert to the aid of General Charles George Gordon at Khartoum, Sudan, who was besieged there by Mahdist forces. The place is generally known in British military records as Abu Klea, which arose as a contemporary British spelling of its Arabic name, 'Abu Tͅuleiħ (أَبُو طُلَيْح). Background The British forces consisted of 1,400 British of the Desert Column under Sir Herbert Stewart, against a Sudanese force of approximately 14,000 fighters. While the main British force (the River Column), led by General Sir Garnet Wolseley travelled by river from Korti to Khartoum, Stewart's column was to cut across country by column directly for Khartoum, since time was running short according to what little information was available from the garrison. The force was composed of four regiments of camel-mounted troops (Guards, Heavy, Light and Mounted Infantry), detachments of the various infantry regiments in Egypt and of the River Column, and a detachment of the 19th Hussars, mounted on horses. Four light field pieces and a small Naval Brigade manning a Gardner machine gun completed the force. Units involved included: 19th Hussars Heavy Camel Detachment Guards Camel Detachment Mounted Infantry Detachment Light Camel Detachment 1st Battalion, Royal Sussex Regiment Royal Marines Light Infantry Royal Navy Brigade Battle The Desert Column arrived on the salient overlooking the wadi of Abu Klea not long before sunset, and Stewart decided not to attack that night. The British built a defensive position (or zariba), but were sniped at from the high ground around them by Mahdist rifle-units - mainly soldiers from southern Sudan - all night. They took several casualties. At first light Stewart ordered them to form a square, which they achieved with perfect discipline, though still under fire from enemy snipers. The square moved slowly towards the wells along the side of the wadi, over very difficult, undulating, rocky ground. Suddenly the square was ambushed by a huge Mahdist force that had been concealing itself in the wadi. The British guns
