Elsewhere, the Allies completed the Operation Ariel evacuation of La Pallice and Saint-Nazaire, but all the heavy equipment were left behind in the latter location. ww2dbase [Invasion of France and the Low Countries | CPC]
  • Sweden allowed passage of German troops between Oslo, Norway, and Trelleborg, Sweden, on Swedish rail lines, with the only demand being that the number of troops coming from Germany must equal to the number being evacuated, so that it could not be said that Sweden was helping Germany reinforce the front lines. ww2dbase [TH]

  • In the afternoon, Italian submarine Galileo Galilei spotted a Yugoslavian steamer Drava in the Gulf of Aden and fired a shot across the bow ordering the ship to stop. After seeing the ship was under a neutral flag, the steamer was allowed to leave. However, the gunfire was heard by the anti-submarine warfare trawler HMS Moonstone, which then fired a warning signal. At around 1630 hours, while the submarine was still on the surface, she was attacked by British aircraft. Galileo Galilei was forced to submerge but remained on stations considering a rather weak response to her sighting. When the darkness fell, the boat resurfaced to recharge the batteries, but it was discovered by the British ship forcing the submarine to crash dive and go through a brief but intense depth-charge attack. ww2dbase [Gulf of Aden | HM]

  • British Prime Minister Winston Churchill made the "the Battle of France is over... I expect that the Battle of Britain is about to begin" speech before the House of Commons. "Let us therefore brace ourselves to our duties, and so bear ourselves that, if the British Empire and its Commonwealth last for a thousand years, men will still say, 'This was their finest hour'." On the same day, Churchill wrote to the Commander-in-Chief Home Forces asking for ideas for the creation of "Storm Troops" to be "ready to spring at the throat of any small landing or descent"; secretly he intended to use such a force as the basis for Commando raids on the continent. ww2dbase [Winston Churchill | London, England | CPC, AC]
