The Nile Expedition, sometimes called the Gordon Relief Expedition (1884–85), was a British mission to relieve Major-General Charles George Gordon at Khartoum, Sudan. Gordon had been sent to the Sudan to help Egyptians evacuate from Sudan after Britain decided to abandon the country in the face of a rebellion led by self-proclaimed Mahdi, Mahommed Ahmed. A contingent of Canadians was recruited to help the British navigate their small boats up the Nile River.
