There is certainly no evidence that any version of the speech, impersonator or not, was broadcast on June 4, 1940. Numerous records detail newsreaders, not Churchill reciting the speech. Regardless, the conspiracy theory spread rapidly. David Irving, a dubious historian and Holocaust denier, ran especially hard with the allegations, claiming Churchill hadn’t really given any of his speeches. A few legitimate historians championed the story as well, but it was thoroughly and repeatedly debunked.
THIS IS OUTSTANDING!!!!!!!!!!! To listen to this man is an honor, and the spread of time that passed and the events that took place with it make it so it ran shivers up and down my spine when I listened to it. I've run it through 4 times so far and I cannot stop. Each time it means more and I hear more. What's so very troubling is the message he delivered to his country long before 'the war' began is very parallel to what's happening in this country right now. And I'm afraid we don't have the stamina, resources, or backbone to rebound like Great Britain did when they had to. Worse we really haven't had leaders like Churchill to make us aware of what's to come. If you have any reservations about buying and listening to this, don't hold back, it's well worth it. I'm happy I have a friend originally born in England while Winston was midway through his wartime endeavor, and I know she will return it to me with the same awestruck review I have of it. Again, don't hold back-Buy It. It's worth twice what I paid for it!

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.”
But the drive to believe and repeat these incorrect memories seems to stem from a desire to remember the war in neater, rosier terms than the actual timeline reveals. (Or, in the case of the Shelley truthers, confirm suspicions about a leader some despise.) There’s a longing to be part of a cultural moment that never existed, yet feels like it must have. While most people experienced Churchill’s cadence through a vinyl recreation years after the fact, those who survived the war would rather believe they heard the thunder and bluster only a privileged few in the House of Commons received in 1940.
This speech made famous the notion of the “Iron Curtain”. Furthermore it defined the parameters of the Cold War. So powerful were Churchill’s words that President Truman had to distance himself from his remarks amid their international notoriety. Yet the speech also outlined the rationale for the “Special relationship” between Britain and the United States. Together, Britain and the US adopted a deep opposition to Communism and, and as a result, it virtually shaped the rest of the rest of the 20th century.
In the House of Commons, some members were moved to tears, but by no means all of them. Although the Dunkirk evacuation had been a remarkable success in its own terms, it had only been necessary because of the sweeping German victories that had humiliated Britain and her allies. Churchill rightly acknowledged that what had happened in France and Belgium had been ‘a colossal military disaster’. The Labour MP Emanuel Shinwell recalled:We were very much depressed as a result of the events that led to him making this speech, and all his oratory could not remove that depression.
If we can stand up to him, all Europe may be free and the life of the world may move forward into broad, sunlit uplands. But if we fail, then the whole world, including the United States, including all that we have known and cared for, will sink into the abyss of a new Dark Age made more sinister, and perhaps more protracted, by the lights of perverted science. 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.’”

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, of which I was speaking just now, 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 manœuvre. 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.

Although President Harry Truman quickly took the measure of the Soviet Union, it was not yet clear whether the United States would embrace a role as the leader of the free world or would link arms with Britain and other Western European nations in a defensive alliance against the Soviet Union. The status and intentions of Soviet forces in Iran and Eastern Europe were uncertain. There was the prospect of Communist takeovers of the governments of France, Italy, and Spain. America was rapidly demobilizing after the victory over Japan barely six months before, and Americans were looking forward to the material blessings of peace. Churchill knew his warning would cast a pall over the mood of the nation.
This might be regarded as Churchill’s farewell address to the House of Commons and established Britain’s approach to nuclear weapons. Churchill, wary of nuclear weaponry, set out to warn the House of their destructive power. He even flirts with the idea of disarmament, but rules it out owning to the international context of the Cold War. He paints a grim picture of the effects of the Hydrogen bomb, but then abruptly changes tone. The Churchillian optimism shrines through in his conclusion:
The final speech was wide-ranging. Churchill gave a detailed recap of the Battle of Dunkirk, praising every member of the Allied forces. But he did not dwell on the lives saved. He warned that the rescue “must not blind us to the fact that what has happened in France and Belgium is a colossal military disaster.” Invasion, he insisted, could be imminent. But he was ready to fight.
While shaving one morning in 1953, Churchill remarked to John Colville, “Today is the 24th of January. It’s the day my father died. It’s the day I shall die, too.” He repeated this prediction to his son-in-law Christopher Soames shortly after his ninetieth birthday, in 1964. A few weeks later, on January 10, 1965, Churchill lapsed into a coma. Earlier that evening, during the nightly ritual of brandy and cigars, he had said to Soames, “It has been a grand journey, well worth making.” He paused and added, “once.”
