At 3.37 AM, U-561 sinks Panamanian SS Crusader in mid-North Atlantic (33 dead). Only survivor is Brazilian coal passer Edward Barreto (possibly rescued by U-561, as he ends up a POW at Milag Nord, Germany, until 1945).

Operation Flipper. British commandos of No.11 (Scottish) Group under Colonels Robert Laycock and Geoffrey Keyes (son of Admiral of the Fleet Sir Roger Keyes) land from submarines HMS Talisman and HMS Torbay to kill Rommel. Due to rough seas, only 36 of the 59 commandos get ashore 12 miles from the target at Beda Littoria.

Operation Astrologer comprises 2 ships, SS Empire Defender and SS Empire Pelican, traveling independently.
