Winston Churchill's rousing speeches inspired a nation and played a key role in maintaining Britain's morale during the dark early days of the Second World War.
His defiant and powerful words allowed ordinary Britons, soldiers, sailors and airmen to feel hope.
He replaced Neville Chamberlain as Prime Minister on May 10 1940.
Days earlier, the 'phoney war', the period of relative calm following the declaration of war on September 3, 1939, had ended with the German invasion of France, Belgium and Holland.
Churchill's first speech as premier to the House of Commons, three days later, would go down in history as one of his most famous.

He said: 'I would say to the House, as I said to those who have joined this government: "I have nothing to offer but blood, toil, tears and sweat."
'We have before us an ordeal of the most grievous kind. We have before us many, many long months of struggle and of suffering.
'You ask, what is our policy? I can say: It is to wage war, by sea, land and air, with all our might and with all the strength that God can give us; to wage war against a monstrous tyranny, never surpassed in the dark, lamentable catalogue of human crime. That is our policy.
'You ask, what is our aim? I can answer in one word: It is victory, victory at all costs, victory in spite of all terror, victory, however long and hard the road may be; for without victory, there is no survival.
'Let that be realised; no survival for the British Empire, no survival for all that the British Empire has stood for, no survival for the urge and impulse of the ages, that mankind will move forward towards its goal.
'But I take up my task with buoyancy and hope. I feel sure that our cause will not be suffered to fail among men. At this time, I feel entitled to claim the aid of all, and I say, 'Come then, let us go forward together with our united strength.' '
Extract from his first broadcast as PM to the country on May 19, 1940.
'I speak to you for the first time as Prime Minister in a solemn hour for the life of our country, of our Empire, of our allies, and, above all, of the cause of freedom . . .
'It would be foolish . . . to disguise the gravity of the hour. It would be still more foolish to lose heart and courage or to suppose that well-trained, well-equipped armies numbering three or four millions of men can be overcome in the space of a few weeks, or even months...
'Side by side, unaided except by their kith and kin in the great Dominions and by the wide empires which rest beneath their shield — side by side, the British and French peoples have advanced to rescue not only Europe but mankind from the foulest and most soul-destroying tyranny which has ever darkened and stained the pages of history.
'Behind them — behind us, behind the armies and fleets of Britain and France — gather a group of shattered states and bludgeoned races: the Czechs, the Poles, the Norwegians, the Danes, the Dutch, the Belgians — upon all of whom the long night of barbarism will descend, unbroken even by a star of hope, unless we conquer, as conquer we must; as conquer we shall.
'Today is Trinity Sunday. Centuries ago, words were written to be a call and a spur to the faithful servants of truth and justice, 'Arm yourselves, and be ye men of valour, and be in readiness for the conflict; for it is better for us to perish in battle than to look upon the outrage of our nation and our altar. As the Will of God is in Heaven, even so let it be.' '
Extract from his Commons speech on June 4, 1940, after the evacuation of 338,000 Allied troops from Dunkirk.
'I have, myself, full confidence that if all do their duty, if nothing is neglected, and if the best arrangements are made, as they are being made, we shall prove ourselves once again able to defend our island home, to ride out the storm of war, and to outlive the menace of tyranny, if necessary for years, if necessary alone.
'At any rate, that is what we are going to try to do. That is the resolve of His Majesty's Government — every man of them. That is the will of Parliament and the nation. The British Empire and the French Republic, linked together in their cause and in their need, will defend to the death their native soil, aiding each other like good comrades to the utmost of their strength.
'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 even 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.'
Extract from his Commons speech on June 18, 1940.
'What General Weygand [the French Allied commander] called the Battle of France is over. I expect that the Battle of Britain is about to begin.
'Upon this battle depends the survival of Christian civilisation. Upon it depends our own British life, and the long continuity of our institutions and our Empire. The whole fury and might of the enemy must very soon be turned on us.
'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.
'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." '
