Following the announcement of the Italian surrender, the bulk of the Italian fleet sailed for Malta - three battleships, cruisers and destroyers from Spezia and Genoa, and three more battleships and other vessels from Taranto and the Adriatic. As the first group came south, battleship "ROMA" was sunk by a FX1400 radio-controlled bomb (unpropelled unlike the Hs293 rocket-boosted, glider-bomb), but next day the remaining ships were escorted into Malta by battleships "Warspite" and "Valiant". Over 30 submarines headed for Allied ports
