However, although Rhodes never belonged to the Greek state before 1946, for the Greeks who largely lived on the island the creation of Italian villages such as Campochiaro and the corresponding change in the ethnological composition of the population was only one of the pressures they were experiencing by the colonization of the Italians.
Another one was the Italianization of the Greeks through the language; the replacement of Greek education by the Italian. Under the leadership of the Quadrumviro of fascism, the new Governor of Rhodes Cesare Maria De Vecchi, now the study of the Greek language became an optional lesson, and only for the first grades of primary school. In the same time, speaking Greek in schools was banned, Greek teachers were replaced by Italians, and all Greek publications were abolished.
Remembering the famous secret school of the Greeks during the years of Ottoman rule, now the Orthodox Bishop of the island, Apostolos, started to organize secret schools for teaching the Greek language in hidden places (such as churches and remote houses), covering it all up as religious catechism.
However, for the Italians in Campochiaro, life went on carefree in a paradise on earth. And it should not have changed much for them when World War II broke out, although many Greeks of the island traveled to the Greek borders with Albania to repel the invasion of fascist Italy in October 1940. In fact the first dead Greek officer of WW2 was from the Dodecanese.
Although the Italian invasion was repulsed by the Greeks, the Germans invaded the country in April 1941 and soon ceded most of Greece, including the islands, to their allied Italian occupation forces. Thus, the German soldiers of the Sturmdivision Rhodos paraded without any problems in the central square of Campochiaro, in front of the then Italian Commander of the Dodecanese, Admiral Inigo Campioni.
Rhodes, now under total control of the Axis, became the stronghold of the latter for the invasion of Crete in the spring of 1941. After the surrender of the Italians in September 1943, following the 2,5 years of their occupation of Rhodes, Germany took control of the island. Losing WW2, the Nazi forces left Rhodes in 8 May 1945, surrendering it to the British - which, in turn, conveyed the Dodecanese to Greece in 1947.
