Many rumors and legends arose after the bombings on Italian cities during the Second World War. According to one of these rumors, some Italian – namely members of the Resistance – reported to the Allied air forces which civilian targets to hit. After the war, neo-fascist press spread the rumor, and so did some attorney during the trials against collaborationists. Former partisans, while firmly rejecting these accusations, testified that the Resistance provided to Allies information only about military targets, always recommending them to spare civilian facilities. The article focuses on the birth and meta-morphosis of the rumor, used from 1944 to 1954 in order to attack anti-fascist political counterparts.
