Olbia's first season in Serie C, with Gesuino Sardo as president and Mario De Palma on the bench, was not too fortunate. In fact, after the first victory in Serie C (1–0) against Stabia, a series of defeats followed, which led to the Sardinian First Division, after just one year, remaining there for three consecutive seasons until the suspension of the championships due to the Second World War. From after World War II to the 1970s After suspending sporting activities because of the war, in the summer of 1947, the bianchi played again in Serie C, finishing in 6th place.
