Oddly enough, some people believe that they did hear it on the radio though. Nella Last, a British housewife who kept diaries during the war, wrote in 1947, “I remember that husky, rather stuttering voice acclaiming that we would ‘fight on the beaches, on the streets. I felt my head rise as if galvanised and a feeling that ‘I’ll be there — count on me; I’ll not fail you.'” Even a Dunkirk soldier thought he had heard the speech, writes Smithsonian. Some began to think they heard an impersonator deliver the words. 

Even though large tracts of Europe and many old and famous States have fallen or may fall into the grip of the Gestapo and all the odious apparatus of Nazi rule, we shall not flag or fail. We shall go on to the end. We shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our island, whatever the cost may be. We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender, and if, which I do not for a moment believe, this island or a large part of it were subjugated and starving, then our Empire beyond the seas, armed and guarded by the British Fleet, would carry on the struggle, until, in God's good time, the New World, with all its power and might, steps forth to the rescue and the liberation of the old.

"From Truman's point of view, the speech was important because the geopolitical situation had changed so much with the defeat of Nazi Germany and the new threat from the Soviet Union," Muller says. "It was somewhat easier to have Churchill, the great English-speaking ally of the United States from the war, to come and warn about the danger from the Soviet Union and from communism than for Truman to do it himself... It wasn't completely original. There had been various observers of foreign affairs who had suggested that this change was about to happen but from the public's point of view, it was really a startling change."
Soon after becoming Prime Minister, Germany invaded France and Britain was alone in Europe fighting Hitler. Churchill inspired the country to keep fighting despite the bad circumstances. He also helped to forge an alliance of Allied Powers with the Soviet Union and the United States. Even though he did not like Joseph Stalin and the communists of the Soviet Union, he knew the Allies needed their help to fight Germany.
As a twenty-six-year old, Churchill took his seat as a Conservative member in the new Parliament and four days later made his maiden speech. He spoke immediately following Lloyd George, ensuring the young politician a very full house. Churchill had, of course, prepared his speech very carefully and more or less learned it by heart. Although this isn’t unusual in a maiden speaker, Churchill – more unusually – continued this meticulous preparation throughout his career.
Turning once again, and this time more generally, to the question of invasion, I would observe that there has never been a period in all these long centuries of which we boast when an absolute guarantee against invasion, still less against serious raids, could have been given to our people. In the days of Napoleon the same wind which would have carried his transports across the Channel might have driven away the blockading fleet. There was always the chance, and it is that chance which has excited and befooled the imaginations of many Continental tyrants. Many are the tales that are told. We are assured that novel methods will be adopted, and when we see the originality of malice, the ingenuity of aggression, which our enemy displays, we may certainly prepare ourselves for every kind of novel stratagem and every kind of brutal and treacherous maneuver. I think that no idea is so outlandish that it should not be considered and viewed with a searching, but at the same time, I hope, with a steady eye. We must never forget the solid assurances of sea power and those which belong to air power if it can be locally exercised.

I have included the title of the speech as given on each record.  It has occasionally been the case that different companies have used different titles.  In those cases, I have included each of the titles used by the recording company.  Since what is common to each is the date of the speech, I provide that as the heading for each speech.  And I present them chronologically.  I have also included in brackets the title given to each speech by Sir Robert Rhodes James in his Winston S. Churchill: His Complete Speeches where the title differs materially from that provided by the recording company since it is that title that will generally be better known to, or easily found by, Churchillians.

The House of Commons has lifted our affairs above the mechanical sphere into the human sphere. It thrives on criticism, it is perfectly impervious to newspaper abuse or taunts from any quarter, and it is capable of digesting almost anything or almost any body of gentlemen, whatever be the views with which they arrive. There is no situation to which it cannot address itself with vigour and ingenuity. It is the citadel of British liberty; it is the foundation of our laws; its traditions and its privileges are as lively today it broke the arbitrary power of the Crown and substituted that Constitutional Monarchy under which we have enjoyed so many blessings.
We shape our buildings, and afterwards our buildings shape us. Having dwelt and served for more than forty years in the late Chamber, and having derived very great pleasure and advantage therefrom, I, naturally, should like to see it restored in all essentials to its old form, convenience and dignity. House of Commons (having met in the House of Lords), 28 October 1943
In 1911 Churchill became First Sea Lord, bringing important changes to the Royal Navy. He recognized the potential of the submarine and airplane, learned to fly, and established the Royal Naval Air Service. However, in 1915, during World War I his ambitious strategy for the Dardenelles led to the debacle at Gallipoli. Forced from the cabinet, he cheerfully returned to the army and commanded a Scottish battalion on the western front. He also was a major factor behind development of the armored fighting vehicle—which he named, for all time, the tank.
Regardless of the origin of the phrase in his Iron Curtain speech, Churchill had been looking ahead to this problem since early in the war. In 1970, the retired prime minister Harold Macmillan related to the thirty-year-old Winston Churchill II a conversation he had had with the young man’s grandfather in early 1942. “It was after a dinner hosted by General Eisenhower for the joint Anglo-American command in Algiers, and your grandfather asked me to come back to his room for a drink. ‘What type of man do you think Cromwell is?’ was his odd question to me.
In many ways, Churchill’s reputation as a speechmaker has been a prisoner of the success he achieved between the fall of France in 1940 and the victory at El Alamein in 1942. What most people know of these speeches is largely ‘confined to a few famous phrases excerpted from a limited number of radio broadcasts in the summer of 1940'. The result is that these ‘quotable bits’ have crowded out other equally important, if less memorable speeches made throughout the war (pp. 2, 229). Nothing better illustrates this point than a speech delivered by Churchill that same summer. With their nation’s defeat, it was altogether likely that the French navy – the world’s fourth largest – would fall into German hands. Before he would let that happen, Churchill took what he later called ‘a hateful decision, the most unnatural and painful in which I have ever been concerned’. With much of the French fleet anchored at Mers-el-Kebir near Oran in North Africa, he ordered the Royal Navy to destroy his former ally’s warships before they could be used by the Nazis against Britain. Churchill’s address to the House of Commons the following day, like the attack itself, is all but forgotten, at least in the English-speaking world; but the immediate impact of both could not have been more significant. The ruthlessness of the assault demonstrated to the world, and especially to the United States, that Britain, in Churchill’s own words, would ‘prosecute the war with the utmost vigour’. For the first time, Conservative MPs joined their Labour and Liberal colleagues cheering the new prime minister, one witness recorded, ‘like mad’ (pp. 62–3). Even if, as Toye suggests, this show of support was stage managed, the Chamberlainite MP, Henry ‘Chips’ Channon, detected a change. ‘At the end of his speech’, Channon recorded in his diary, ‘the House rose, cheered, waved Order Papers – as I have so often seen them do for Neville. Only it was not little Neville’s turn now. Winston suddenly wept’,(3) (Toye does not fully quote this part of Channon’s diary, which is unfortunate. It is a minor oversight, but there are others that are not – about which more later.)
