In late September, the Italian fleet, including "Fiume", made a sweep for a British troop convoy from Alexandria to Malta, but it made no contact with the British ships. "Fiume" was present in the harbor at Taranto when the British fleet launched the nighttime carrier strike on Taranto on the night of 11–12 November, but she was not attacked in the raid. Another attempt to intercept a British convoy in late November resulted in the Battle of Cape Spartivento. The Italian fleet left port on 26 November and clashed with the British fleet the next day, in an engagement that lasted for about an hour. Campioni broke off the action because he mistakenly believed he was facing a superior force, the result of poor aerial reconnaissance. The British heavy cruiser HMS "Berwick" was hit twice by 203 mm rounds during the engagement, either fired by "Fiume" or her sister "Pola".
