On March 9, 1945, in the Italian town of Salussola, Italian Fascist soldiers executed 20 Italian Partisans after torturing them. The fascists intended the massacre as an act of retaliation for an attack conducted a few days earlier by other Partisans on a column of military trucks under the "Montebello"'s Fascist Command.
