The British Expedition to Abyssinia was a rescue mission and punitive expedition carried out in 1868 by the armed forces of the British Empire against the Ethiopian Empire (also known at the time as Abyssinia). Emperor Tewodros II of Ethiopia, then often referred to by the anglicized name Theodore, imprisoned several missionaries and two representatives of the British government in an attempt to force the British government to comply with his requests for military assistance. The punitive expedition launched by the British in response required the transportation of a sizable military force hundreds of miles across mountainous terrain lacking any road system. The formidable obstacles to the action were overcome by the commander of the expedition, General Sir Robert Napier, who was victorious in every battle against the troops of Tewodros, captured the Ethiopian capital, and rescued all the hostages. The expedition was widely hailed on its return for achieving all its objectives.
