Therefore, when talking about the future course and conduct of the war in this speech, Churchill had to describe a great military disaster, and warn of a possible German invasion attempt, without casting doubt on eventual victory. He needed to prepare his domestic audience for France's departure from the war without in any way releasing France to do so; in his subsequent speech of 18 June immediately after the French had sued for peace Churchill said:
When Neville Chamberlain succeeded Baldwin, the gulf between the Cassandra-like Churchill and the Conservative leaders widened. Repeatedly the accuracy of Churchill’s information on Germany’s aggressive plans and progress was confirmed by events; repeatedly his warnings were ignored. Yet his handful of followers remained small; politically, Chamberlain felt secure in ignoring them. As German pressure mounted on Czechoslovakia, Churchill without success urged the government to effect a joint declaration of purpose by Great Britain, France, and the Soviet Union. When the Munich Agreement with Hitler was made in September 1938, sacrificing Czechoslovakia to the Nazis, Churchill laid bare its implications, insisting that it represented “a total and unmitigated defeat.” In March 1939 Churchill and his group pressed for a truly national coalition, and, at last, sentiment in the country, recognizing him as the nation’s spokesman, began to agitate for his return to office. As long as peace lasted, Chamberlain ignored all such persuasions.
I have always said that if Great Britain were defeated in war I hoped we should find a Hitler to lead us back to our rightful position among the nations. I am sorry, however, that he has not been mellowed by the great success that has attended him. The whole world would rejoice to see the Hitler of peace and tolerance, and nothing would adorn his name in world history so much as acts of magnanimity and of mercy and of pity to the forlorn and friendless, to the weak and poor. ... Let this great man search his own heart and conscience before he accuses anyone of being a warmonger.
The ‘fight them on the beaches’ speech was delivered in the House of Commons; it was never broadcast though it was reported on the BBC by an announcer and quoted in the press. However, people claim to remember having heard this famous speech from June 1940, even though they hadn’t. It was recorded for posterity along with others of his wartime speeches nine years later.
Nevertheless, our thankfulness at the escape of our Army and so many men, whose loved ones have passed through an agonizing week, must not blind us to the fact that what has happened in France and Belgium is a colossal military disaster. The French Army has been weakened, the Belgian Army has been lost, a large part of those fortified lines upon which so much faith had been reposed is gone, many valuable mining districts and factories have passed into the enemy’s possession, the whole of the Channel ports are in his hands, with all the tragic consequences that follow from that, and we must expect another blow to be struck almost immediately at us or at France. We are told that Herr Hitler has a plan for invading the British Isles. This has often been thought of before. When Napoleon lay at Boulogne for a year with his flat-bottomed boats and his Grand Army, he was told by someone. “There are bitter weeds in England.” There are certainly a great many more of them since the British Expeditionary Force returned.
