By early 1941, Italian forces had been largely pushed back from Kenya and Sudan. On 6 April 1941, Addis Ababa was occupied by the 11th (African) Division, which received the surrender of the city. The remnants of the Italian forces in the AOI surrendered after the Battle of Gondar in November 1941, except for groups that fought an Italian guerrilla war in Ethiopia against the British until the Armistice of Cassibile (3 September 1943) ended hostilities between Italy and the Allies.
