カラブリア沖海戦
Although mainly used as fleet escorts, these ships also laid minefields and escorted convoys. During one such duty, they missed the Battle of Calabria and were never involved in a major fleet action. Two were lost before the Italian surrender: one torpedoed and one lost in a storm. Another, under repair at the surrender, was scuttled to avoid German capture. The fourth, "Grecale", joined the Allies and was involved in actions against the Germans and survived into post-war Italian service.
