In the last two years before the start of World War II, Italy almost broke off diplomatic contact with Yugoslavia and started negotiations with Germany and the Ustaše. Italy recalled General Gambara from Spain in 1940 so that he could take control of forces which would attack Banovina of Croatia (a Yugoslav province). This offensive was only delayed because of the Italian declaration of war against France on 10 June 1940. Italy created plans of attack on Yugoslavia in February 1940 with the primary objective of taking Šibenik, Split and Kotor so that the Adriatic situation would be eased. The only problem with this plan was that Hitler wanted to create an alliance between the two kingdoms against Greece. During negotiations in late 1940, Italy offered Thessaloniki to Yugoslavia but it was rejected. Only when Hitler put forward a similar offer in March 1941 was it accepted, and Yugoslavia become a member of the Axis powers on 25 March 1941. Hitler ordered an attack on Yugoslavia following the coup d'état on 27 March; two days later the new Yugoslav prime minister, Dušan Simović, asked for Italian help in restoring relations with Germany. Simović warned Italy that Yugoslavia would overrun Italian Albania if the Axis powers declared war. This war would start on 6 April 1941 and end with the destruction of the Yugoslav Kingdom on 17 April.
