Tremendous air-battle this afternoon, about 3 o’clock. The sirens sounded, and we had a full crowd in the Vaults. I went up on the roof, and very soon the air seemed full of the screaming of falling planes. We have all heard the sound so often on films that it really seems quite natural, and one tends to forget that is real, and that you are watching young men go down to a particularly unpleasant death. We could see burning planes to the E., W., and S., and I saw one of our fighters make a forced landing in the E., somewhere near Gt. Bromley I should think. All this took place in brilliant sunshine.
To Rose for supper.
