Ethiopian resistance, particularly in the wake of a failed assassination attempt on Viceroy Rodolfo Graziani in February 1937, led to him being listed as a war criminal by the Ethiopian government, which attempted to have him extradited to Ethiopia after the Second World War. In 1938, he returned to Rome, until 3 August as Honorary Governor of Galla-Sidamo, but in 1939, he was promoted to army corps general and sent to command the Bari Army Corps. Promoted to army corps general, he was sent in October to command first the VII Army Corps at Trieste and then, on 1 December, the XXVI Army Corps, comprising the Italian garrison (XXVI Army Corps) in Italian-occupied Albania. Geloso remained in Albania until 6 June 1940. During his tenure, he planned for an attack on Greece,, and elements of his plans were indeed used in the subsequent Italian invasion of Greece, but it was under quite different conditions and participating forces from his plans. Although a capable organiser, he was helpless in the backroom political manoeuvring that characterized the Fascist regime. After disagreeing with Foreign Minister Galeazzo Ciano, Mussolini's heir-apparent, during a discussion of a possible war with Greece on 23 April 1941, he was replaced by Sebastiano Visconti Prasca. World War II and occupation of Greece Italy's entry into World War II found him as head of the Third Army, but he returned to Albania on 15 November 1940 to take up command of the newly formed Eleventh Army in the ongoing war against Greece. After the German invasion of Greece and the start of the country's occupation, in September 1941 he was named Supreme Commander of the Italian Armed Forces in Greece, while remaining commander of Eleventh Army. He kept both positions until his dismissal in May 1943. In October 1942, he was promoted to army general. His tenure in Greece earned him criticism from many sides. The Greeks naturally resented him as the commander-in-chief of the Italian occupation forces and the brutality that he displayed in anti-partisan operations. However, the Italians' German allies considered him too "weak" and ineffective despite his reputation as a loyal adherent to the Axis alliance. Geloso opposed the Germans' demands for even harsher retaliations and even resisted the demands for implementation of discriminatory measures against Greek Jews in the Italian occupation zone. On the other hand, Geloso in spring 1943 approved the institution of collective punishment
