Partisan attacks on local Fascists soon began, while larger partisan groups formed on the nearby mountains; on 31 October Riva and Count Federico Gaschi led a punitive expedition against partisans in the Val di Susa, despite Solaro's prohibition, but the expedition ended in disaster, suffering several casualties including Riva, who was killed. Solaro then had Count Gaschi placed under arrest. Starting from November 15, FIAT workers began a strike which soon extended to other factories, owing to low wages that were insufficient due to the rising cost of life; Solaro went to Fiat Mirafiori to speak with the workers and persuaded the German authorities to a grant a 30% wage increase in December. While facing these problems, Solaro also had to keep under control the diverging currents within the local PFR, several of which were trying to split and form their own party.Michele Tosca, I ribelli siamo noi, pp. 33-40-44-51-55-57-66-67-70-82-84Nicola Adduci, Gli altri.
