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.
