One commander in this war later ordered the massacre of the monks in the Debre Libanos monastery after an assassination attempt. Carl Gustav von Rosen witnessed the destruction of a Red Cross hospital by one side in this conflict, and after the death of pilot Tito Minniti that side began using chemical weapons. One leader in this conflict escaped to Jerusalem on board the HMS Enterprise and stated "It is us today. It will be you tomorrow" in a telegram. Robert Vansittart was responsible for negotiating one attempt to end this war, which attempted to bring one side back into the (*) Stresa Front and give the other side a "corridor for camels"; that was the Hoare-Laval pact. This conflict was precipitated by a clash at the Wal Wal fort. The League of Nations' condemnation of this war led to the withdrawal of one side from that organization, and this event ended with the March of the Iron Will and the exile of Haile Selassie. For 10 points, name this 1935-6 war in which Benito Mussolini annexed an African nation.
