Battle of Calabria
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.
