With the Axis invasion of Yugoslavia and the Balkans, Italy annexed Ljubljana, Dalmatia and Montenegro, and established the puppet states of Croatia and Greece. Following Vichy France's collapse and the Case Anton, Italy occupied the French territories of Corsica and Tunisia. Italian forces had also achieved victories against insurgents in Yugoslavia and in Montenegro, and Italo-German forces had occupied parts of British-held Egypt on their push to El-Alamein after their victory at Gazala.
