During this period two incidents of note occurred. One was that the Child suddenly developed pleurisy, and was removed to hospital—a serious loss at any time, but especially so at this particular moment. The other was that a squadron of hostile aircraft flew over our manœuvre ground and actually dropped a bomb within 150 yards of the tail of our column. Which, seeing that we were some twenty miles from the nearest part of the line and at the moment only playing at soldiers, was most disconcerting. From the time when we left this training area until, about three weeks later, we were withdrawn to rest in a quiet part of the line, I kept a rough diary of our particular share in the greatest battle ever fought by the British Army. The following are some extracts from it, in no way embellished, but only enlarged so as to make them intelligible. _June 27._—Nine-hour night march southwards, arriving in comfortable billets at 3.30 A.M. Aeroplanes (or at any rate, hostile ones) are the curse of this war: if it was not for fear of them we could move by daylight in a reasonable manner. The old saddler, dozing on a wagon, fell off and was run over: nothing broken, but he will be lost to us. A great pity, as he’s a charming character and a first-class workman. _June 28 and 29._—Rested, the continuation of the march having been postponed. _June 30._—Orders to move on to-night. Was sent off with a small party on a road and river reconnaissance: this presumably with a view to going forward ‘when the advance begins.’ By the time we got back to where the brigade was to billet, had ridden about forty miles. Job only half finished. Battery marched in at midnight. _July 1._—Started at 5.30 A.M. with same party to finish reconnaissance. Reached a point about four miles behind the line, at 7.15 A.M.: a tremendous bombardment in progress. Left our horses, and walked on two miles to a river. Here learnt that the attack had been launched at 7.30 and was going well. Walked north up the river-bank, keeping well under the shelter of the steep ridge on the east side, and only emerging to examine each bridge as we came to it. Thousands upon thousands of shells of every size, from ‘Grannies’ to 18-prs., passing over our heads unceasingly: expected the enemy to retaliate. But not a round came: probably the Boche was too busily engaged elsewhere. Met streams of wounded coming down; some with captured helmets, nearly all with grins. Finished the river reconnaissance about 10.30 and walked back by a roundabout (but less unpleasant!) way, and reached our horses about midday. Rode back to the battery and spent the afternoon writing out full report. Orders to move at 11.30 P.M. Long night march to new billets, arriving 4.15 A.M.
