The weather now took a turn for the worse, there being a sort of cloud-burst on the 12th. Cross-country tracks were impassable for infantry, and the carriage of ammunition to the new gun positions was a very heavy task. The rain came at an unfortunate moment. Battalions of the 109th Brigade were moving up to Aveluy Wood, south of Mesnil, to complete the work of preparation. The 16th Rifles (Pioneers) were there already. These troops had to endure the gravest discomfort from the weather. Little canvas shelters were all their protection, and for days together their clothes were not dry. Yet their work was magnificent. When, almost at the last moment, a Regiment of French Field Artillery joined the Division to assist in the attack, the 11th Inniskillings were ordered to help them in the construction of gun-pits and shelters, with little enough time to do it. The men threw themselves into the task with splendid enthusiasm. It seemed that they worked the harder because their work was for strangers, who would be left half-protected if they failed them. There was a fine flavour of international courtesy in the manner of their toil, for they gave of their free will energy that not the most skilful of taskmasters could have wrung from them. General Nugent sent to Colonel Brush, then in command of the Battalion, a letter of warm congratulation upon their efforts. In the battle that was about to begin, General Sir H. Rawlinson's Fourth Army was taking the offensive along its whole front, with the Sixth French Army of General Fayolle on its right. The Battle of the Somme, the first in which our New Armies of volunteers were engaged in great numbers, concerned the 36th Division but at its opening. Its general aspects were, however, of the highest importance to all the Allied troops. It differed broadly from such an action as that of Loos. There an immediate strategic result was sought from a small offensive. Here, while a break through was sought on the first day, and would doubtless have been possible had the whole German trench system been captured all along the front, thereafter the aims became quite other. On the vast plateau of Picardy, an advance of ten miles or thereabouts had small strategic importance. The nearest first-class railway junction, Cambrai, was thirty miles away. The new phase was the "limited offensive." The plan was to push forward infantry behind artillery fire of overwhelming weight upon a broad front, step by step, smashing down resistance. The plan was made possible for us by the huge development of our munition factories. It was the war of attrition. It was a mighty assault battle, wherein England and France hurled man and gun and material upon German man and gun and material. It had manifold and obvious blemishes. Its cost was prodigious, particularly in its early stages, before certain needful lessons had been learnt. It stereotyped attack and robbed commanders of initiative, and was in this respect the text-book of
