Second Italo-Ethiopian War
East African campaign, 1940–1941

While in exile in United Kingdom, Haile Selassie had sought the support of the Western democracies for his cause but had little success until the Second World War began. On 10 June 1940, Mussolini declared war on France and Britain and attacked British and Commonwealth forces in Egypt, Sudan, Kenya and British Somaliland. In August 1940, the Italian conquest of British Somaliland was completed. The British and Selassie incited Ethiopian and other local forces to join a campaign to dislodge the Italians from Ethiopia. Selassie went to Khartoum to establish closer liaison with the British and resistance forces within Ethiopia. On 18 January 1941, Selassie crossed the border into Ethiopia near the village of Um Iddla and two days later rendezvoused with Gideon Force. The Allied East Africa Command and Ethiopian patriots had largely succeeded in their operations by 6 April 1941, when Addis Ababa was occupied by Harry Wetherall, Dan Pienaar and Charles Christopher Fowkes, who received the surrender of the city; on 5 May, exactly five years after the fall of the capital, Selassie made a formal entry in Addis Ababa. After the Italian defeat, the Italian guerrilla war in Ethiopia was carried out by remnants of Italian troops and their allies, which lasted until the Armistice between Italy and Allied armed forces in September 1943.
