[3] Averoff escaped a year later and created the "Freedom or Death" resistance group, which aimed to liberate Greek and Allied war hostages.

Evangelos Averoff was a prominent author of political and historical works, such as "Customs Union in the Balkans" (1933), which the Carnegie Institute awarded, "Fire and Axe, 1944–1949" (1974) dealing with the Greek Civil War, and "A History of missed opportunities: The Cypriot Problem 1956–1963" (1981).

He played a leading role in the founding of the Foundation of Baron Michael Tositsas, which he ran for 40 years, thus contributing greatly to the contemporary development of the town of Metsovo.

He also founded the Evangelos Averof-Tositsas Foundation,[5] to which he donated his significant personal collection of paintings by Greek artists of the 19th and early 20th century and built a gallery to house it.

In particular, Fallaci claims that Panagoulis was in possession of secret documents showing Averoff's direct involvement in brokering the transition from the Joannides Junta to a national unity government led by Konstantinos Karamanlis, keeping himself in charge of managing the relations between the democratic system and the Armed Forces.
