But, soon after the Italian invasion, the Greeks counter-attacked and a sizable portion of Albania was in Greek hands (including the cities of Gjirokastër and Korçë). In April 1941, Greece capitulated after an overwhelming German invasion. All of Albania returned to Italian control, which was also extended to most of Greece, which was jointly occupied by Italy, Germany and Bulgaria. Italian plans however to annex Chameria to Albania were shelved due strong opposition and ethnic conflict between Albanians and Greeks, as well as opposition by Aromanians to the region being Albanianized.
