Churchill had declined a steady stream of high-profile speaking invitations in the first months after the war, including those from the kings and queens of Norway, Denmark, and Holland, as well as from Canada and Australia. “I refuse,” said Churchill, “to be exhibited like a prize bull whose chief attraction is his past prowess.” But Churchill could hardly turn down an invitation than came from the White House in September 1945. Churchill opened it and saw that it was an invitation to speak at Westminster College in a town he had never heard of. Scoffing, he threw it down and said, “I supposed colleges in America are too named ‘Parliament.’” But his daughter Sarah read it and saw that there was a postscript at the bottom of the invitation. “This is a wonderful school in my home state. Hope you can do it. I’ll introduce you. s/g Harry Truman.”

Where I put “Commons” in brackets following the speech title, it of course indicates that the speech was recorded by Churchill subsequent to its date of delivery in the House, as there was no audio recording of Commons proceedings in Churchill’s day.  That first occurred on 3 April 1978, long after Churchill’s days in Parliament.  I add, as a point of interest, the fact that video broadcasts of proceedings on the floor of the House began on 21 November 1989.

Note, finally, that I have not included other 33 rpm albums which state that they include Churchill speeches or extracts without identifying them.  Thus, for example, the BBC Scrapbooks for 1940 and 1945, and several of the Edward R. Murrow I Can Hear It Now albums (issued on 78 rpm and 33 rpm records).  I have not been able to listen to them all in order to identify the speeches in question and so have opted to not identify those collections of speeches.
This speech may be regarded as the most important Churchill delivered as Leader of the Opposition. It contains certain phrases - “the special relationship,” “the sinews of peace “ - which at once entered into general use, and which have survived. But it is the passage on “the iron curtain” which attracted immediate international attention, and had incalculable impact upon public opinion in the United States and in Western Europe. This speech ultimately defined the parameters of the Cold War.
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.
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.
