Miller, Marshall Lee.Bulgaria During the Second World War. — Stanford University Press, 1975. — С. 129. — ISBN 0-8047-0870-3.. — «In Greece the Bulgarians reacquired their former territory, extending along the Aegean coast from the Struma (Strymon) River east of Thessaloniki to Alexandroupolis on the Turkish border. Bulgaria looked longingly toward Salonika and western Macedonia, which were under German and Italian control, and established propaganda centres to secure the allegiance of the approximately 80,000 Slavs in these regions. The Bulgarian plan was to organize these Slavs militarily in the hope that Bulgaria would eventually assume the administration there. The appearance of the Greek left wing resistance in western Macedonia persuaded the Italian and German and authorities to allow the formation of Slav security battalions (Ohrana) led by Bulgarian officers.".
