Giovanni Ravalli was born on 21 September 1909 in
Monterosso Almo. During the course of
World War II, Ravalli served in the
24th Infantry Division Pinerolo, 13th Infantry Regiment, in the rank of
Lieutenant. In this capacity he became the head of intelligence of the
Italian garrison in the city of
Kastoria, Greece. Despite the heavy presence of the Italians in Kastoria, its outskirts remained in the control of
EAM-ELAS guerrillas which in turn received wide support from local Greeks,
Slavic speakers,
Vlachs and elements of the collaborationist
Hellenic Gendarmerie. Ravalli went on to establish links with
Andon Kalchev's
Ohrana (a pro-Bulgarian Slavic-speaking militia) and German troops stationed at
Florina, disarming the Gendarmerie to cut short ELAS' weapon supply. In July 1943, ELAS stepped up its attacks around Kastoria, exploiting a period of Italian passivity. News of the
Allied invasion of Sicily caused a drop in morale among Ohrana's ranks, leading to desertions. In August, the Pinerolo Division began to gradually withdraw from Kastoria as Italy was on the edge of signing an
armistice with the Allies. Ravalli surrendered to ELAS along with 15 Ohrana members. ==Trial and imprisonment==
