Snow was falling heavily at this time, and the trench-tours were kept down to four or five days. After three weeks of this experience, the Battalion was relieved on March 5th by the 9th Inniskilling Fusiliers, of the 36th (Ulster) Division, and went into billets at Harponville. It is observed that ‘during the three weeks the Brigade had been in the trenches, a great deal of work was done by the newly appointed Intelligence Officers, and practically everything possible was known about No Man’s Land.’ The Intelligence Officer in the 7th West Yorkshires was 2/Lieut. Beale, but for old acquaintance’ sake, we select an example of such service, which provided valuable knowledge for future use, from the record of Lieut. E. F. Wilkinson, M.C., of the 8th Battalion of the same Regiment. At mid-day on February 28th he went out to certain cross-roads. Again, on the afternoon of March 2nd, he waded up the stream which flowed under a stone bridge just west of these cross-roads, and found a plank bridge twenty-five yards up-stream, which, judging by the marks on it, was regularly used by the Germans. The information which this officer obtained in his daylight prowlings helped to compose the map of No Man’s Land; and it is worth observing that a German War Diary (2nd Guard Reserve Division), to which we refer later on, acknowledges that British Officers ‘were provided with excellent maps, which showed every German trench systematically named, and gave every detail of our positions.’ We are writing of the preparations for the Somme battles. ‘These preparations’, said Sir Douglas Haig,[52] ‘were necessarily very elaborate and took considerable time. Vast stocks of ammunition and stores of all kinds had to be accumulated beforehand within a convenient distance of our front. To deal with these, many miles of new railways, both standard and narrow gauge, and trench tramways were laid.’ In the Harponville period, we now read, all the Companies of the 7th West Yorkshires ‘were employed in working on a new railway, which was in course of construction from Daours to Contay.’ This work, assisted by good weather, ‘nearly every day being warm and sunny,’ was finished on March 26th. On the 30th, there was an inspection by Lord Kitchener, who expressed his approval of the appearance and turn-out of the men. The 5th Battalion of the West Yorkshires, which was billeted in Harponville at the same time, shared in the work and the inspection. Day by day they were called upon for working-parties to construct new roads, new railways, or both; and ‘all this labour,’ Sir Douglas Haig reminds us, writing of the Army as a whole, ‘had to be carried out in addition to fighting, and to the everyday work of maintaining existing defences. It threw a very heavy strain on the troops, which was borne by them with a cheerfulness beyond all praise[53].’ Certainly no sign of lack of cheerfulness is revealed in the diary of any unit. ‘The men liked the change of work,’ we are told.
