On this day in 1940, British troops evacuate France in Operation Ariel, an exodus almost on the order of Dunkirk. Meanwhile, British Prime Minister Winston Churchill offers words of encouragement in a broadcast to the nation: "Whatever has happened in France... [w]e shall defend our island home, and with the British Empire we shall fight on unconquerable until the curse of Hitler is lifted."
With two-thirds of France now occupied by German troops, those British and Allied troops that had not participated in Operation Dynamo, the evacuation of Dunkirk, were shipped home. From Cherbourg and St. Malo, from Brest and Nantes, Brits, Poles, and Canadian troops were rescued from occupied territory by boats sent from Britain. While these men were not under the immediate threat of assault, as at Dunkirk, they were by no means safe, as 5,000 soldiers and French civilians learned once on board the ocean liner Lancastria, which had picked them up at St. Nazaire. Germans bombers sunk the liner; 3,000 passengers drowned.
Churchill ordered that news of the Lancastria not be broadcast in Britain, fearing the effect it would have on public morale, since everyone was already on heightened alert, fearing an imminent invasion from the Germans now that only a channel separated them. The British public would eventually find out—but not for another six weeks—when the news finally broke in the United States. They would also enjoy a breather of another kind: Hitler had no immediate plans for an invasion of the British isle, "being well aware of the difficulties involved in such an operation," reported the German High Command.
