ITALY: British troops advance on Sicily almost unopposed. They take Pozzallo. US advance is resisted by the Hermann Göring  Panzer division.

TERRITORY OF ALASKA: ALEUTIAN ISLANDS: Five Eleventh Air Force B-24s take off from Attu Island to attack the Kataoka Naval Base on Shimushu Island in the Kurile Islands and fly a shipping search but are turned back by a heavy cloud front extending from the surface of the sea to 6,000 feet (1,829 meters); this is the first attempt to bomb Japan by heavy bombers in World War II. ]

A shipping search by 5 B-25 Mitchells finds nothing. 6 B-25s and 6 B-24s in 3 missions (one by radar) attack North Head and Main Camp on Kiska Island sighting new excavations near Sredni Point, strafe a tent near Haycock Rock, and also fly over Segula Island.

CANADA: Destroyers HMCS Iroquois, HMS Douglas along with frigates HMCS Moyala and Swale were escorting the troopships Duchess of York, California and Port Fairy from Plymouth to Freetown, South Africa when they were attacked by 3 German Focke Wulf 200 'Kondor' high-altitude bombers at about 2100 hrs 200 miles off of Vigo, Spain. The German bombing accuracy was excellent and both California and Duchess of York were hit and burned furiously. The consorts evacuated both ships and the 2 damaged liners were sunk by gunfire and the convoy continued on to an unscheduled stop at Casablanca. Twenty-seven lives were lost in this incident. 680 survivors were rescued from Duchess of York by Iroquois. Duchess of York was the 2nd and last of the 4 CPR Duchess-class liners lost during the war. The 1st was Duchess of Atholl on 12 Oct 42; several other CPR liners were also lost.) She was a veteran of the evacuations from Norway and France and had travelled widely on hazardous routes. She was regarded as a lucky ship. During one of her 6 voyages to North Africa she had survived a hit by an unexploded bomb. The Duchess-class liners had been designed with a flat-bottomed hull for travelling up the St.Lawrence River, which gave them a significant roll. This characteristic trait caused them to be dubbed "The Drunken Duchesses". The 2 survivors, Duchess of Bedford and Duchess of Richmond, were renamed Empress of France and Empress of Canada after the war. The CPR lost 14 of its original 22 ships during WW II. Empress of Britain (42,348 tons) was the largest Allied passenger liner to be sunk and the biggest merchant ship loss of the war.
