Why did Churchill say this? Why did he choose to qualify his great heroic statement in this way? After all, it gave Nazi propagandists the chance to claim that he was planning to skedaddle, as according to German radio,the war could, of course, never be conducted from another hemisphere unless Churchill and his confederates were there to conduct it.
The position of the B. E.F had now become critical As a result of a most skillfully conducted retreat and German errors, the bulk of the British Forces reached the Dunkirk bridgehead. The peril facing the British nation was now suddenly and universally perceived. On May 26, “Operation Dynamo “–the evacuation from Dunkirk began. The seas remained absolutely calm. The Royal Air Force–bitterly maligned at the time by the Army–fought vehemently to deny the enemy the total air supremacy which would have wrecked the operation. At the outset, it was hoped that 45,000 men might be evacuated; in the event, over 338,000 Allied troops reached England, including 26,000 French soldiers. On June 4, Churchill reported to the House of Commons, seeking to check the mood of national euphoria and relief at the unexpected deliverance, and to make a clear appeal to the United States. 

Once the decision had been made, Churchill was Overlord’s fierce advocate. He reveled in the tactics and gadgets that characterized the greatest amphibious operation yet attempted—he was especially taken with the Mulberry portable harbors. He also informed Eisenhower of his intention to observe the landings from a British cruiser. The supreme commander replied that Churchill was far too valuable to risk and prohibited it. Churchill calmly replied that as a British citizen he would sign on aboard one of His Majesty’s ships, whereupon Eisenhower’s headquarters contacted Buckingham Palace. King George thereupon called Churchill, declaring that if the prime minister went to Normandy, the monarch could do no less. Churchill relented.

Correctness of diction.“Diction” is often used to refer to articulation, but its primary meaning is word choice—think of dictionary. Our digital culture of text messages, tweets, and email has impacted our spoken language, often reducing it to monosyllables, idioms, and clichés. This is not to say that you should use long or esoteric words. Aspire to precision and clarity when you speak.
Against this loss of over 30,000 men, we can set a far heavier loss certainly inflicted upon the enemy. But our losses in material are enormous. We have perhaps lost one-third of the men we lost in the opening days of the battle of 21st March, 1918, but we have lost nearly as many guns — nearly one thousand-and all our transport, all the armored vehicles that were with the Army in the north. This loss will impose a further delay on the expansion of our military strength. That expansion had not been proceeding as far as we had hoped. The best of all we had to give had gone to the British Expeditionary Force, and although they had not the numbers of tanks and some articles of equipment which were desirable, they were a very well and finely equipped Army. They had the first-fruits of all that our industry had to give, and that is gone. And now here is this further delay. How long it will be, how long it will last, depends upon the exertions which we make in this Island. An effort the like of which has never been seen in our records is now being made. Work is proceeding everywhere, night and day, Sundays and week days. Capital and Labor have cast aside their interests, rights, and customs and put them into the common stock. Already the flow of munitions has leaped forward. There is no reason why we should not in a few months overtake the sudden and serious loss that has come upon us, without retarding the development of our general program.

Churchill’s reputation as an orator is based principally on his speeches and broadcasts as Prime Minister during the summer of 1940, in particular those known usually as ‘Blood, toil, tears and sweat’ (13 May), ‘We Shall Fight on the Beaches’ (4 June) and ‘This was their Finest Hour’, which was delivered to the House of Commons on 18 June and broadcast by the BBC to the nation later that evening.
In this situation he found relief, as well as profit, in his pen, writing, in Marlborough: His Life and Times, a massive rehabilitation of his ancestor against the criticisms of the 19th-century historian Thomas Babington Macaulay. But overriding the past and transcending his worries about India was a mounting anxiety about the growing menace of Hitler’s Germany. Before a supine government and a doubting opposition, Churchill persistently argued the case for taking the German threat seriously and for the need to prevent the Luftwaffe from securing parity with the Royal Air Force. In this he was supported by a small but devoted personal following, in particular the gifted, curmudgeonly Oxford physics professor Frederick A. Lindemann (later Lord Cherwell), who enabled him to build up at Chartwell a private intelligence centre the information of which was often superior to that of the government. When Baldwin became prime minister in 1935, he persisted in excluding Churchill from office but gave him the exceptional privilege of membership in the secret committee on air-defense research, thus enabling him to work on some vital national problems. But Churchill had little success in his efforts to impart urgency to Baldwin’s administration. The crisis that developed when Italy invaded Ethiopia in 1935 found Churchill ill prepared, divided between a desire to build up the League of Nations around the concept of collective security and the fear that collective action would drive Benito Mussolini into the arms of Hitler. The Spanish Civil War (1936–39) found him convinced of the virtues of nonintervention, first as a supporter and later as a critic of Francisco Franco. Such vagaries of judgment in fact reflected the overwhelming priority he accorded to one issue—the containment of German aggressiveness. At home there was one grievous, characteristic, romantic misreading of the political and public mood, when, in Edward VIII’s abdication crisis of 1936, he vainly opposed Baldwin by a public championing of the King’s cause.
However, Smithsonian writes that the most surprising thing, is that Churchill’s speech was not broadcast over the radio to the British public, and that most Britons and Americans did not hear the speech until decades later. And the recording that has been heard round the world was actually recorded in 1949, from the comfort of his own home. The House of Commons was not wired for sound in 1940, so any public broadcast would have to be delivered again, specifically for radio. But Churchill was too busy and uninterested to do this, and so radio journalists just reported his words on the air.

To make note of the complexity of the origins and responses to this wonderful speech by no means implies criticism of Churchill. Rather, it prompts us to rethink the factors that contributed to his oratorical success. He did not merely provide uplifting soundbites; he presented a factual and reasoned case, provided the public with new information and, crucially, provided them with the context necessary to understand it. He was willing to run the risk of depressing his audience if this would serve the greater purpose of bringing them into contact with reality; he did not attempt to win easy popularity by providing false hope. He followed this formula throughout the war, not always with complete success in terms of audience response, but with the ultimate achievement of establishing his credibility as someone who would deliver the facts no matter how unpalatable they might be. This is a lesson which modern orators will do well to follow.
We are also told that the Italian Navy is to come to gain sea superiority in these waters. If they seriously intend it, I shall only say that we shall be delighted to offer Signor Mussolini a free and safeguarded passage through the Straits of Gibraltar in order that he may play the part which he aspires to do. There is general curiosity in the British Fleet to find out whether the Italians are up to the level they were at in the last war or whether they have fallen off at all
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.”
