However, the German eruption swept like a sharp scythe around the right and rear of the Armies of the north. Eight or nine armored divisions, each of about four hundred armored vehicles of different kinds, but carefully assorted to be complementary and divisible into small self-contained units, cut off all communications between us and the main French Armies. It severed our own communications for food and ammunition, which ran first to Amiens and afterwards through Abbeville, and it shore its way up the coast to Boulogne and Calais, and almost to Dunkirk. Behind this armored and mechanized onslaught came a number of German divisions in lorries, and behind them again there plodded comparatively slowly the dull brute mass of the ordinary German Army and German people, always so ready to be led to the trampling down in other lands of liberties and comforts which they have never known in their own. 

In the book, I do not criticise Churchill’s speeches, except for noting the obvious misfires, on which Matthews himself comments. Churchill was clearly an excellent speechmaker, and there was no-one else available who could conceivably have done the task better. He enjoyed enviably high levels of popularity, and that he made a strong positive contribution to British morale, both through his speeches and through other aspects of his leadership. (That is not the same thing, though, as saying that his speeches made the decisive difference between victory and defeat.) What I am arguing is that, nevertheless, the speeches generated considerably more criticism and controversy them than we are usually led to think, either by academic historians or by media representations. The fact of this dissent is still perfectly consistent with millions of people having been inspired and galvanised by the speeches in exactly the way that we have always been told. And by highlighting the criticisms, it is certainly not my intention to endorse them: many, undoubtedly, were misconceived. But if we do not acknowledge and understand them, then we can neither comprehend the political world in which Churchill was operating, nor appreciate the true nature of his oratorical success. (I reflect on the latter here: It is clear to me from my email inbox and postbag that many people think that to draw attention to contemporary negative reactions is equivalent to denigrating the speeches themselves and indeed Churchill the man. Paradoxically, though, Churchill’s anti-appeasement speeches of the 1930s are valorised exactly because he ploughed on when so many people disagreed with him!

…1941, Roosevelt and Prime Minister Churchill announced the formation of the United Nations, a wartime alliance of 26 nations. In 1943 Roosevelt began planning the organization of a postwar United Nations, meeting with congressional leaders to assure bipartisan support. The public supported Roosevelt’s efforts, and that fall Congress passed resolutions…
Few failed to recognise Churchill's part in Britain's survival and victory. But after six years of war, people wanted more than just a return to the old order. They wanted reform and reconstruction of Britain. On 26 July 1945, Churchill learned that he and the Unionists (Conservatives) had been rejected by the people. Labour, under Clement Attlee, would govern Britain in the immediate post-war world.
This memorandum and other actions of Churchill around the time of the Agadir made the prime minister, H. H. Asquith, realize that Churchill needed a more prominent government post from which to influence the nation’s strategic destiny. Within a few weeks of the resolution of the Agadir crisis, Asquith had elevated Churchill to First Lord of the Admiralty, in which office Churchill introduced a number of forward-looking reforms and innovations that echo down to the present day.
But the escalating situation in Europe was getting hard to ignore. Churchill rose to the Prime Ministry on May 10, 1940, coinciding with the end of the so-called “Phoney War,” a period stretching from September 1939, with the declaration of war against Germany, to the spring of 1940, a period with no major military land operations on the European continent. That stagnation ceased after the Nazis invaded Denmark and Norway in April. The Battle of Dunkirk -- which would incur heavy Allied casualties, prompt a Belgian surrender, and precipitate the fall of France -- commenced in May.
The gratitude of every home in our Island, in our Empire, and indeed throughout the world, except in the abodes of the guilty, goes out to the British airmen who, undaunted by odds, unwearied in their constant challenge and mortal danger, are turning the tide of the World War by their prowess and by their devotion. Never in the field of human conflict was so much owed by so many to so few. All hearts go out to the fighter pilots, whose brilliant actions we see with our own eyes day after day; but we must never forget that all the time, night after night, month after month, our bomber squadrons travel far into Germany, find their targets in the darkness by the highest navigational skill, aim their attacks, often under the heaviest fire, often with serious loss, with deliberate careful discrimination, and inflict shattering blows upon the whole of the technical and war-making structure of the Nazi power.

Both the war against Nazi Germany and efforts to stop the Holocaust were hampered by anti-Semitism. Axis propaganda sought to portray Churchill, who was sympathetic to Zionist aims and had many Jewish friends, as part of a supposed Jewish conspiracy. Nevertheless, Churchill expressed his outrage as the scale of the Nazi atrocities against the Jews became apparent. It was, he said, "probably the greatest and most horrible crime ever committed in the whole history of the world." Related Objects
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:
The Churchill wilderness years have been likened to the Biblical prophet Jeremiah, who pleaded in the desert for the people of Israel to change their ways. Others compare him to Cassandra, the prophetess of Troy whom Apollo cursed with always being unheeded. The best comparison is that of the Athenian orator Demosthenes, who wielded his rhetorical gifts to warn of the military threat from Philip II of Macedon. The Athenians ignored Demosthenes’ “philippics” until war was upon them.

While largely unstated, one of Churchill’s major concerns was limiting Soviet territorial gains in Europe. Having an eye toward the postwar world, he did not want Stalin in control of formerly democratic nations. However, geopolitics required further cooperation with his unlikely ally, and Churchill met Roosevelt for the last time in Stalin’s domain—Yalta in the Crimea, in February 1945. Victory in Europe was visible by then, though with more hard fighting to come in the Pacific. Roosevelt’s premature death in April ended the original Big Three.
