4th May (1918)

Did a picquet in the small still hours.  During the night Fritz dropped a string of heavy bombs.  Though bombs are no more dangerous than shells everyone hates them – they drop with a kind of menacing throb-b-b throb-b-b! and an unseen aeroplane, by some acoustic peculiarity, always sounds directly overhead.

Novel sight of dropping of propaganda balloons over Hun’s lines.  Bright blue in colour.  Don’t know by what arrangement they are regulated, probably clockwork.
