At five minutes to twelve the moon was shining on a peaceful but desolate scene; the frogs were croaking in the shell-holes, and the only signs of war were an occasional Verey light beyond Ypres and the lazy droning of a night bomber overhead. At midnight there was a crash behind us and instantly our guns let out together, surrounding us with a wall of noise and leaping, white-hot flame. The S.O.S. began to rise from the German lines and shortly afterwards the steady crashing of his shrapnel barrage was added to the din. This went on steadily for three-quarters of an hour, while we grovelled on our stomachs in the mud, and punctually at 12.45 settled down to the usual desultory shelling. Had only one casualty in my party, but he was a nasty sight—chewed to pieces by a direct hit. On the way back Mellor and I cycled into some gas and swallowed a bit before we got our bags on—coughing and sneezing all night and had devilish headache. Just outside Vlamertinghe we ran into a smashed ambulance and four limber mules and two drivers literally splashed about the road—our wheels were wet with warm blood. Later on we found a saddle-horse blown in two but could not see any signs of the rider. One of the worst nights I have had since March! _May 22._ Quiet day testing my charges on the bridges. Very hot and water unobtainable—tried thirst quenchers, which were worse than nothing. White with dust, and eyes, nose, and mouth full of it. _May 23._ Another quiet day testing charges. Derry twice shelled off his job but had no casualties. _May 24._ Heavy rain last night converted everywhere into a quagmire. _May 25._ Beautiful hot day again. Completed work on demolitions and finished all preliminary testing. _May 26._ Busy day handing over demolitions—jolly glad to be rid of them although it means front line work instead. Very heavy shell-fire all night followed by Bosche attack, in which he captured Ridge Wood and Scottish Wood. Had seven casualties, and had to ride all the way home in gasmask. Hear that the Durhams have been very badly hit—two companies almost entirely gone. _May 27._ Am posted as Reserve Officer to our forward company in addition to my own work. Working under the new major on Main Reserve Defences. Bosche still shelling very persistently all morning, especially round Brandhoek, where he fired a large petrol dump. Picked up some shrapnel which fell within two or three yards of me. Putting in a double machine-gun post in the top of a ruined windmill—splendid field of fire and view right away to the foot of Kemmel Hill. God help Jerry if these gunners stick it! Also constructed a very strong double post in a farm on the Switch road.
