Rather cold, mostly cloudy. Did shopping locally in morning including posting some Xmas parcels, letters and cards. Wrote letter to Harold Conrade also sent a card and also a book he lent me. A very heavy bomb explosion in afternoon which shook the house to its foundations and rattled the windows, followed at intervals of a few minutes by two other reports getting successively less severe. Mr.Norriss said an unfamiliar plane had just gone over in a S.E. direction where the sounds came from. It was announced that an enemy plane was shot down off the S.E. coast this afternoon but it was not stated if it had penetrated inland and dropped bombs. It seems likely as surely all the delayed bombs must have been disposed of by now.
