At 7 p.m. the head of the battalion arrived at Sand-bag Corner, a junction of roads with a great sand-bag barricade on the way to Chapelle d'Armentières, where guides awaited us. The companies were to hold in the order "D," "A" (now commanded by Captain Wyatt), "C" from the right, with "B" Company in reserve in the subsidiary line, which "B" Company, 2/7th K.L.R., proceeding viâ Gris Pot and La Vesée, had already taken over, as extra company in the subsidiary line, from a company of the 2/4th South Lancashire Regiment. For the first time the men wore their packs detached from their equipment on kicking-straps, this again being due to the possibility of a raid; and in future this was the order for all reliefs, the manifold advantages being very obvious. The last part of the route up to the subsidiary line was along a lane full of shell-holes, but the frequent illumination produced by German Véry lights made the going fairly simple. Transport came right up to Battalion Headquarters, and dumps were formed accordingly in the subsidiary line for Headquarters and for each company. The relief proceeded quietly and without incident, and its speed was naturally increased by the possibility, owing to their number, of having "up" and "down" communication trenches--Wine Avenue and Leith Walk the former; Park Row, Wellington Avenue, and Cowgate the latter. At 12.40 a.m. on March 30th relief was reported complete, and our friends of the 2/5th South Lancashire Regiment proceeded joyfully to Crown Prince House and the reserve billets in the Rue Marle. The tour, in spite of the gloomy forebodings of the gunners, proved quiet enough. For the first night or two strong fighting patrols lay up in No Man's Land in the hope of catching the enemy raiding party. The Germans, however, showed no signs of any hostile intent, and after a day or two the various precautions that had been adopted were discarded. The left sector came in for a considerable amount of shelling, particularly in the vicinity of Captain Eccles's Headquarters and also the Ferme de Biez in rear of it, which our observers used to haunt. However, there was plenty of room in the sector for shells to fall without doing any serious harm, and our casualties were, fortunately, very low in consequence. In the right company's front a stream came in under the front line and wandered across the sector. Strict orders had been issued that the water was not to be used for drinking or cooking, inasmuch as it came from the enemy's line. Walking round one day, Captain McHugh, our newly arrived and most delightful Irish Medical Officer, took a sample for analysis through curiosity. It was interesting to learn that a strong arsenic result was obtained.
