Rather cold, very dull, rain at night. Went for a walk on Wimbledon Common to see where the bombs fell on Caeser's Camp. Saw 3 craters including a large hole where two unexploded bombs fell: I did not venture nearer than 30 yards. One was just inside the circle of trees at Caeser's well. I saw some model aeros being flown. Mrs Akroyd to tea. Night raid at 8.3 p.m. Upwards of 30 machines came here, some heavily fired at. Heard bombs whistling down not far away but did not hear them explode. Distant all clear at 11.43 p.m. more distant still at 11.59 a.m. on 10th Mon. Distant all clear at 1.5 a.m. local at 1.22 a.m. Distant al clear at 1.44 a.m. Warning at 2.30 a.m. enemy aircraft from N. to S. not fired at. All clear 2.50 a.m. Immediately followed by low flying bomber which came from the south turned about overhead and went back again: not fired at at all. In this raid the Germans appeared to be using the device of showers of small delayed bombs which exploded at irregular periods up to several hours. Distant all clear from N.E. at 3.30 a.m.
