In East Africa... Cunningham's South African troops take Diredawa, Abyssinia, in their advance west to Addis Ababa. The local Italian population has appealed to the British for help because of atrocities committed by deserters from the native forces after the Italian part of the garrison has withdrawn.

In the Mediterranean... Battle of Cape Matapan. The British give up the chase and return to port. In whole the operation the British lose two aircraft. The training of the British forces is given some credit for the success.
