The mention of these things may make dull reading to the _blase_ warrior of later battlefields, but, as there are some whose last experience abroad was during Laventie days and who may read these lines, I feel bound to recall our old friend (or enemy) the trench mortar, the rent-free (but not rat-free) dug-out among the sandbags, the smelly cookhouses, whose improvident fires were the scandal of many a red-hatted visitor to the trenches, the mines, with their population of Colonial miners doing mysterious work in their basements of clay and flinging up a welter of slimy blue sandbags--all these deserve mention, if no more, lest they be too soon forgotten. Days, too, in Riez Bailleul, Estaires and Merville will be remembered, days rendered vaguely precious by the subsequent destruction of those villages and by lost comrades. Those of the Battalion who fell in 1916 were mostly buried in Laventie and outside Merville. Though both were being fought over in 1918 and many shells fell among the graves, the crosses were not much damaged; inscriptions, if nearly obliterated, were then renewed when, by the opportunity of chance, the Battalion found itself once more crossing the familiar area, before it helped to establish a line upon the redoubtable Aubers ridge, to gain which so many lives at the old 1915 battles of Neuve Chapelle and Festubert had been expended. It was a fine autumn. The French civilians were getting in their crops within a mile or two of the trenches, while we did a series of tours in the Moated Grange sector, with rest billets at the little village of Riez Bailleul. And then box respirators were issued. Laventie days are remembered with affection by old members of the Battalion. In October, 1916, however, there were some not sorry to quit an area, which in winter became one of the wettest and most dismal in France. The Somme battle, which for three months had rumbled in the distance like a huge thunderstorm, was a magnet to attract all divisions in turn. The predictions of the French billet-keepers were realised at the end of October, when the 2/4th Oxfords were relieved in the trenches by a battalion of the Middlesex Regiment and prepared to march southwards to the Somme.
