British destroyer HMS Kelly with Lord Louis Mountbatten aboard went on patrol in the Skagerrak between Sweden and Germany, escorted by cruiser HMS Birmingham and destroyers HMS Kandahar, HMS Bulldog, HMS Kimberley, and HMS Hasty. Five German torpedo boats attacked this fleet in the evening. Torpedo boat S-31 damaged HMS Kelly with one torpedo, killing 27; she would require HMS Bulldog to tow her back to port.
