A friend came to see me on one of the evenings of the last week — he thinks it was on Monday, August 3rd. We were standing at a window of my room in the Foreign Office. It was getting dusk, and the lamps were being lit in the space below on which we were looking. My friend recalls that I remarked on this with the words: ‘The lamps are going out all over Europe, we shall not see them lit again in our life-time’.
