In the Mediterranean... The British Mediterranean Fleet attacks the Italian base at Taranto. During the night 21 Swordfish aircraft attack in two waves and gain three torpedo hits on the brand new battleship Littorio and one each on Caio Duilio and Conte di Cavour. Two other ships are damaged. The aircraft have come from the carrier Illustrious and only two are lost. This brilliant attack will certainly be studied by other navies and the potential for such an attack on an enemy fleet in harbor is clear to the Japanese.

Over Britain... In a postscript to the main actions a force of Italian bombers, protected by biplane fighters, is sent to attack Harwich. They are intercepted and lose six planes for no loss to the RAF. The Italians make other attacks, mostly by night, on east-coast ports during the next nine weeks.
