At 5 p.m. on November 29, 1916, the Germans opened a heavy barrage with howitzers on the front line, giving every indication of impending attack. Regina Trench, where were the headquarters of C and D, the companies then holding the line, was also heavily shelled, and telephonic communication with the rear was soon cut. On such occasions it was always difficult to decide whether or not to send up the S.O.S--on the one hand unnecessary appeal to our artillery to fire on S.O.S. lines was deprecated, on the other, no forward commander could afford to guess that a mere demonstration was on foot; for the appearance of attacking infantry followed immediately on a lifting of the barrage, a symptom in itself often difficult to recognise. On this occasion I intended and attempted to send up a coloured rocket, but its stick became stuck between the sides of the dug-out shaft and, by the time the efforts of Sergeant Collett had prepared the rocket for firing, the barrage died down as suddenly as it had started. This very commonplace episode illustrates the routine of this phase of warfare. The trenches were, of course, blown in and some Lewis guns damaged, but, as frequently, few casualties occurred. While speaking of the life furthest forward I do not forget the very similar conditions, allowing for the absence of enemy machine-guns and snipers, which prevailed at Battalion Headquarters. Confined to a dug-out (a smaller replica of Regina) in Hessian Trench, with a continual stream of reports to receive and instructions to send out, and being continually rung up on the telephone, Colonel Bellamy and Cuthbert had their hands full, and opportunities for rest, if not for refreshment, were very limited. Nor do I omit our runners from the fullest share in the dangers and activities of this time. Under battle-conditions life at one remove from the front line was rarely much more agreeable than in the line itself, and was less provided with those compensations which existed for the Infantryman near the enemy. It was necessary to go back to Divisional Headquarters to find any substantial difference or to live an ordered life on a civilised footing; and there, too, responsibility had increased by an even ratio. The Battalion Transport during this time was stationed at Martinsart and its task, along bad roads, in bringing up rations each day was not a light one.
