Operation Compass. 80 miles West of Tobruk, British tanks attack an Italian fort at Mechili in the Libyan desert.

In the Indian Ocean 300 miles East of the Seychelles, a Heinkel He114 seaplane from German armed merchant cruiser Atlantis bombs and strafes British SS Mandasor (carrying 2,000 tons of pig iron & 1,800 tons of tea from Calcutta, India). As Mandasor steams away radioing for help, Atlantis stops her with shellfire (6 crew killed). Atlantis’ launch rescues 82 survivors, driving off circling sharks with machinegun fire, and then sends Mandasor to the bottom with scuttling charges. The He114 seaplane capsizes in choppy water and has to be sunk, robbing Atlantis of spotting capabilities. 4 Allied cruisers search the area without success.
