U.S.A.: German submarines sink two more unarmed U.S. merchant tankers. U-159 shells a tanker in the Caribbean about 175 miles (282 km) south of the Windward Passage. After the crew abandons ship, the ship is sunk by demolition charges set by a boarding party from the sub. The unescorted and unarmed E.J. Sadler was taken under fire by U-159 about 175 miles south of the Windward Passage, as the tanker was 36 hours out of port and proceeding on a nonevasive course at 8.4 knots. At 2035, U-159 began to shell the ship from a distance of about four miles. The lookouts on the tanker had not seen the U-boat until it opened fire, but now the vessel immediately swung the stern toward it and the radio operator began sending distress signals. Eight of the first ten rounds from the 10.5cm gun were hits and the crew of eight officers and 28 men abandoned ship in four lifeboats. U-159 then fired another 75 rounds and 175 rounds from the 37-mm Anti-Aircraft gun into the tanker at close range, which set the ship on fire, but the ship remained afloat. After four hours a boarding party was sent aboard and placed scuttling charges, which finally sank the ship. The next morning a PBY aircraft spotted the survivors and directed destroyer USS Biddle, which picked them up 20 hours after the attack and brought them to Mayaguez, Puerto Rico.

 In the Gulf of Mexico, U-67 torpedoes and sinks a tanker about 40 miles (64 km) off the coast of Louisiana.
