German battlecruisers Scharnhorst and Gneisenau were detected by aircraft of the British Coastal Command; they were met by German aircraft at 1900 hours, escorting them as they headed for Brest, France. Meanwhile, two ships that they had captured 5 days prior, tankers Bianca and San Casimiro, were spotted by British aircraft from carrier HMS Ark Royal; battleship HMS Renown would advance in an attempt to recapture. The German crew scuttled both tankers before surrendering themselves along with the 46 prisoners of war aboard the two ships.
