In the course of my wild peregrinations over the camp in search of my valise, I came upon a group of Tommies undergoing instruction in the machine-gun. Arrested by a familiar voice, I recognised as instructor a man I had known very well at Cambridge! He recognised me at the same moment, and in a few seconds we parted, after an invitation from him to dinner that evening; he was on “lines of communication” work, he told me. Sitting in his tent after Mess, I was amazed at the apparent permanence of his abode; shelves, made out of boxes; novels, an army list, magazines, maps; bed, washstand, candlesticks, a chair; baccy, and whisky and soda! It was all so snug and comfortable. I was soon to find myself accumulating a very similar collection in billets six miles behind the firing-line, and taking most of it into the trenches! I remember being impressed by the statement that the cannonade had been heard day after day since the 25th, and still more impressed by references to “the plans of the Staff!” I left Étaples early on the morning of the 7th, after receiving instructions, and a railway warrant for “Chocques,” from a one-armed major of the Gordons. Of our original twelve only Terry and Crowley remained with me; with a young Scot, we had a grey-upholstered first-class carriage to ourselves. In the train I commenced my first letter home; and I should here like to state that the reason for the inclusion in these first chapters of a good many extracts from letters is that they do really represent my first vague, rather disconnected, impressions, and are therefore truer than any more coherent account I might now give. First impressions of people, houses, places, are always interesting; I hope that the reader will not find these without interest, even though he may find them at times lacking in style. [Illustration: _To face page 9_ MAP I.] “I am now in the train. We are passing level-crossings guarded by horn-blowing women; the train is strolling leisurely along over grass-grown tracks, and stopping at platformless stations. It is very hot. At midday I shall be about ten miles from the firing-line, and I expect the cannonade will be pretty audible. I feel strangely indifferent to things now, though I have the feeling that all this will be stamped indelibly on my memory.” How well I remember the thrill of excitement when I found the name Chocques on my map, quite close to the firing-fine! And as we got nearer, and saw R.A.M.C. and cavalry camps, and talked to Tommies guarding the line, saw aeroplanes, and yes! a captive balloon, excitement grew still greater! At last we reached Chocques, and the railway transport officer calmly informed us that we had another four miles to go. He brilliantly suggested walking. But an A.S.C. lorry was there, and in we climbed, only to be ejected by the corporal! Eventually we tramped to Béthune with _very_ full packs in a hot sun.
