In the South Pacific, Kapitän zur See Robert Eyssen brings German armed merchant cruiser Komet (now separated from cruiser Orion) back to British island of Nauru to destroy the phosphate export facility. Eyssen warns dock personnel to evacuate and not send distress signals. As no signals are sent, Komet waits before shelling the loading platforms, cranes and oil tanks (torching 13,000 tons of oil). Nauru’s dock will be rebuilt in 10 weeks but will not return to full capacity during the war.
200 miles South of Iceland, Italian submarine Tazzoli sinks British SS Ardanbhan (all 37 crew lost).
German cruiser Admiral Hipper returns to Brest, France, after an unsuccessful patrol lasting 1 month and sinking only 1 ship.
At 11.31 PM 300 miles off Senegal, U-65 uses a torpedo and 70 rounds from the deck gun to sink Norwegian SS Risanger (carrying coal and vehicles to British forces at Alexandria, Egypt, around the Cape of Good Hope rather than going through the Mediterranean). All 29 crew take to the lifeboats and are picked up after a few days by Norwegian tanker MV Belinda and landed in Capetown on Jan 10 1941.
