Though conditions were never quiet in the front line, during the summer of 1916 back area shelling was infrequent. Shells fell near Laventie cross-roads on most days and, when a 12 inch howitzer established itself behind the village, the Germans retaliated upon it with 5.9s, but otherwise shops and estaminets flourished with national nonchalance. The railway, which ran from La Gorgue to Armentieres, was used by night as far as Bac St. Maur--an instance of unenterprise on the part of German gunners. Despite official repudiation, on our side the principle of 'live and let live' was still applied to back areas. Trench warfare, which in the words of a 1915 pamphlet 'could and must cease' had managed to survive that pamphlet and the abortive strategy of the battle of Loos. Until trench warfare ended divisional headquarters were not shelled. Meanwhile the comparative deadlock in the Somme fighting rendered necessary vigorous measures against the enemy elsewhere on the front. A gas attack from the Fauquissart sector was planned but never carried out. Trench mortars and rifle grenades were continuously employed to make life as unpleasant as possible for the enemy, whose trenches soon became, to all appearances, a rubbish heap. All day and much of the night the 'mediums' fell in and about the German trenches and, it must be confessed, occasionally in our own as well. Whilst endeavouring to annihilate the Wick salient or some such target, one of our heaviest of heavy trench mortars dropped short (perhaps that is too much of a compliment to the particular shot) in our trenches near a company headquarters and almost upon a new concrete refuge, which the R.E. had just completed and not yet shown to the Brigadier. Though sometimes supplied, the co-operation of this arm was never asked for.
