Ciano volunteered for action in the Italian invasion of Ethiopia (1935–36) as a bomber squadron commander. He received two silver medals of valor and reached the rank of captain. His future opponent Alessandro Pavolini served in the same squadron as a lieutenant. Upon his highly trumpeted return from the war as a "hero" in 1936, he was appointed by Mussolini as replacement Foreign Minister. Ciano began to keep a diary a short time after his appointment and kept it active up to his 1943 dismissal as foreign minister. In 1937, he was allegedly involved in planning the murder of the brothers Carlo and Nello Rosselli, two exiled anti-fascist activists killed in the French spa town of Bagnoles-de-l'Orne on 9 June. Also in 1937, prior to the Italian annexation in 1939, Gian Galeazzo Ciano was named an Honorary Citizen of Tirana, Albania.
