In the Mediterranean... Admiral Cunningham leads three battleships and several other vessels of the British Mediterranean Fleet to bombard the Italian positions at Bardia and Fort Capuzzo. Air attacks on the ships are beaten off.

Over Germany... The RAF sends a raid against the armament works at Leuna. Although at this stage of the war the RAF intends to hit only military targets, it cannot achieve the necessary accuracy in night bombing.

In Greece... Following recently increased tension with Italy, the Greek armed forces are partially mobilized with a call-up in some districts. Among the provocations is the sinking of the Greek cruiser Helle by an Italian submarine.

Over Britain... There are no major German attacks even though the weather is reasonably good. In response to pleas from Dowding the Air Ministry agrees to give Fighter Command some extra pilots from other RAF branches and to shorten the training period for new pilots even though this has obvious disadvantages.
