Churchill finally retired in 1955 at the age of eighty-one. He continued writing, speaking, and painting for the next decade, gaining additional honors. His multivolume history The Second World War received the 1953 Nobel Prize for literature, but he wrote twenty other histories and biographies as well. That same year he was knighted by Queen Elizabeth. He was made an honorary American citizen in 1963.
After he was stricken, the Times commented, “Life is clearly ebbing away, but how long it will be until the crossing of the bar it is impossible to say.” Not for the first time the Times was wrong about Churchill. It was possible to say how long it would be—Churchill had already said it. Colville told the queen’s private secretary, “He won’t die until the 24th.” Though Churchill seldom regained consciousness in the two weeks that followed, he survived to the predicted date. Churchill had survived his father by precisely three score and ten years—the full biblical lifetime—and had fulfilled many of his father’s ambitions as well as his own.
There is no evidence that any version of the speech, imposter or not, was broadcast on June 4, 1940. But Smithsonian writes that there are a few reasons behind the false memories. Perhaps there is a drive to remember the war in rosier terms than the actual details reveal. Or potentially people long to be part of a cultural moment, even if it didn’t exist.

“We shall go on to the end,” Churchill said. “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.”

Reference: Speech in the House of Commons, also known as "The Few", made on 20 August 1940. However Churchill first made his comment, "Never in the field of human conflict was so much owed by so many to so few" to General Hastings Ismay as they got into their car to leave RAF Uxbridge on 16 August 1940 after monitoring the battle from the Operations Room. Churchill repeated the quote in a speech to Parliament four days later complimenting the pilots in the Royal Air Force during the Battle of Britain. The speech in the House of Commons is often incorrectly cited as the origin of the popular phrase "never was so much owed by so many to so few"
Here was the source of my mother’s indomitable spirit which shone strongly even in her last years. I vividly remember one Christmas, when at the age of 79 she fell from the top of her stairs all the way down to the bottom. Not only did she survive, battered and bruised as she was, but she was up and dressed Christmas morning, determined the day would not be ruined. I knew this amazing toughness had been moulded by the events of the Second World War, and along with all her generation, it had been shaped in steel by Churchill’s remarkable speeches.

Here we see the significance of Churchill’s remark that he was confident that Britain could continue the war for years, ‘if necessary alone’. At this point the French were still in the war, so the hint that they might drop out was alarming to many. Churchill’s warning was timely and necessary but, by the same token, the concern that it generated was also wholly understandable. It may well be true that millions of people were, at the same time, galvanised and invigorated by the speech. But the recorded reactions of contemporaries show us that Churchill’s task was in some ways more complicated than is generally credited.

Hitler knows that he will have to break us in this Island or lose the war. 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.

He had been in the habit of totally memorising his speeches. But from this point forward, Churchill decided to forge a system of speech writing that employed copious notes and several revisions. It was this system which helped create the powerful and awe inspiring oratory which Churchill had envisioned as a 23-year-old in 'The Scaffolding of Rhetoric’ and for which Churchill has become famous. So in many ways, it was from this small failure that day in the House of Commons that Churchill’s amazing oratory was born.

First, Poland has been again overrun by two of the great powers which held her in bondage for 150 years but were unable to quench the spirit of the Polish nation. The heroic defense of Warsaw shows that the soul of Poland is indestructible, and that she will rise again like a rock which may for a spell be submerged by a tidal wave but which remains a rock.
You cannot tell from appearances how things will go. Sometimes imagination makes things out far worse than they are; yet without imagination not much can be done. Those people who are imaginative see many more dangers than perhaps exist; certainly many more than will happen; but then they must also pray to be given that extra courage to carry this far-reaching imagination. But for everyone, surely, what we have gone through in this period - I am addressing myself to the School - surely from this period of ten months this is the lesson: never give in, never give in, never, never, never, never-in nothing, great or small, large or petty - never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy. We stood all alone a year ago, and to many countries it seemed that our account was closed, we were finished. All this tradition of ours, our songs, our School history, this part of the history of this country, were gone and finished and liquidated. 

For five years I have talked to the House on these matters – not with very great success. I have watched this famous island descending incontinently, fecklessly, the stairway which leads to a dark gulf. It is a fine broad stairway at the beginning, but after a bit the carpet ends. A little farther on there are only flagstones, and a little farther on still these break beneath your feet. [ ... ] Look back upon the last five years – since, that is to say, Germany began to rearm in earnest and openly to seek revenge ... historians a thousand years hence will still be baffled by the mystery of our affairs. They will never understand how it was that a victorious nation, with everything in hand, suffered themselves to be brought low, and to cast away all that they had gained by measureless sacrifice and absolute victory – gone with the wind! Now the victors are the vanquished, and those who threw down their arms in the field and sued for an armistice are striding on to world mastery. That is the position – that is the terrible transformation that has taken place bit by bit.
Winston Churchill (1874–1965) served as the Prime Minister of Great Britain from 1940 to 1945 and again from 1951 to 1955. He led Britain's fight against Nazi Germany in World War II. Churchill was a talented orator, giving many stirring speeches to boost national morale during the war. A close friend of American presidents Franklin D. Roosevelt and Harry S. Truman, Churchill hoped to join the Americans in building a postwar order that limited Soviet leader Joseph Stalin's ability to dominate European affairs.
In November 1915 Churchill resigned from the government and returned to soldiering, seeing active service in France as lieutenant colonel of the 6th Royal Scots Fusiliers. Although he entered the service with zest, army life did not give full scope for his talents. In June 1916, when his battalion was merged, he did not seek another command but instead returned to Parliament as a private member. He was not involved in the intrigues that led to the formation of a coalition government under Lloyd George, and it was not until 1917 that the Conservatives would consider his inclusion in the government. In March 1917 the publication of the Dardanelles commission report demonstrated that he was at least no more to blame for the fiasco than his colleagues.
given the recent turn of events in the world, I became very interested in Churchill. This book does a good job of presenting some of his most famous speeches and giving the reader a look at a tremendous speaker and exceptional human being. His complete speeches fill several books, so this is a lot more user friendly for those who want the more condensed version.
