Mild, cloudy, calm; not unpleasant. In morning to buy cats food. Prepared seed bed and sowed onion seed. Dearest Gladys called. Fitted sheet of corrugated iron to door of shelter so as to armour it. Night raid at 9.3 p.m. Probably the worst raid of all. The planes made an uproar for hours without a break, the sky seeming to be full of them. Many bombs dropped some must have been very near; also the sky was lit up by incendiary bombs and later the whole sky was aglow with the light of many fires. All clear at 4.56 on17 Thur.
