British Prime Minister Winston Churchill gives one of his finest speeches in the House of Commons, reviewing the conduct of the war in France and Belgium “the German eruption swept like a sharp scythe around the right and rear of the Armies of the North….. cut off all communications between us and the main French Armies”,
the evacuation of Dunkirk “We must be very careful not to assign to this deliverance the attributes of a victory. Wars are not won by evacuations”
and the prospect of invasion of the Britain “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” (text and MP3 at http://www.fiftiesweb.com/usa/winston-churchill-fight-beaches.htm, stream all Churchill speeches http://www.archive.org/details/Winston_Churchill)
