Sir Winston’s oratorical skills were world famous, and he started developing them at an early age. When he was just 23, he wrote an unpublished paper called “The Scaffolding of Rhetoric,” in which he offered five “principal elements” to win over audiences. With all due respect to Sir Winston’s estimable writing skills, I’ve taken the liberty of extending his 1897 verbiage (bolded) into modern times:
With Chamberlain’s policies and moral authority irrefutably discredited, Churchill became prime minister on 10 May 1940. Immediately faced with the fall of France and the possible invasion of England, Churchill directed his immense energy and ability to defense of Shakespeare’s ‘‘scepter’d isle.’’ He shrugged off suggestions by some right-wing politicians and allegedly a few members of the royal family to reach an accommodation with Hitler. Through the summer and fall the Battle of Britain was fought and won in English skies, and the Nazi invasion fleet—such as it was—never sailed. Churchill’s masterful oratory gripped the world’s attention in concert with the epic events unfolding about him.
He justified the low level of support it had been possible to give to France since Dunkirk, and reported the successful evacuation of most of the supporting forces. He resisted pressure to purge the coalition of appeasers, or otherwise indulge in recrimination. He reviewed the forces still available to prevent or repel any attempted invasion,[b] summing up the review as follows:
Winston Churchill steered Britain through its darkest hours during World War II. He was one of the 20th century’s greatest orators, and the speeches that he painstakingly composed, rehearsed, and delivered inspired courage in an entire nation. Churchill’s output was prolific—his complete speeches alone contain over 5 million words. On this special recording, the best and most important of those have been brought together in this historic volume. Using digitally remastered archive recordings, they include: ‘Blood, toil, tears and sweat’ / ‘The Few’ / ‘This was their finest hour’ / ‘We can take it!’ / ‘An Iron Curtain has descended’ / ‘Never give in!’ / ‘A total and unmitigated defeat’ / ‘Give us the tools.’ Winston Churchill oversaw some of the most important events the world has ever seen and was the most eloquent and expressive statesman of his age. These speeches help reveal the man behind the defiant orator and demonstrate why, in a national poll, Sir Winston Churchill was voted "Greatest Briton of All Time."
Expecting that the German offensive would develop along much the same lines as it did in 1914, the lines of communication of the British Expeditionary Force (BEF) did not run through the "short crossing" Channel ports – Boulogne, Calais, Dunkirk, etc. – but rather through Dieppe and Le Havre. On 13 May, the Wehrmacht's attack through the Ardennes had reached the Meuse River at Sedan and then crossed it, breaking through the defences of the French Army. By 20 May, Wehrmacht armoured divisions had reached the coast of the English Channel, splitting the BEF and the French First Army from the main French forces.
