They were relieved (August 15) by a battalion from the 5th Brigade, who “had heard all sorts of dreadful stories about the position.” “But I told them,” said Colonel Trefusis, “it was not so bad, provided their bombers kept on bombing at night. Mines, of course, one cannot help, and the only way to minimise their effect is to keep as few men in the front line as possible.” And so, Colonel the Hon. J. Trefusis passes out of the Battalion’s story, to his new headquarters and his new staff and bombing officers, and his brand-new troops, who “simply out of curiosity to see what was going on put their heads over the parapet while under instruction and so lost two men shot through the head, which I hope will be a lesson to them.” He had commanded the Battalion since November, 1914, and no sudden occasion had found him wanting. The Diary says: “It is impossible to say all that he has done for the Battalion,” and indeed, high courage, unbroken humour, a cool head, skill, and infinite unselfishness are difficult things to set down in words. He was succeeded in the command by Major G. H. C. Madden who arrived from England on the 16th August, when the Battalion was in rest at Béthune and the hands of their company and platoon officers were closing upon them to make sure once more that such untidy business as mining, counter-mining, and crater-fighting had not diminished smartness on parade. This was doubly needful since the 4th (Guards) Brigade ceased, on the 19th August, to be part of the First Army and became the 1st Guards Brigade in the newly formed Guards Division of four Battalions Grenadiers, four Coldstream, two Scots, two Irish, and the Welsh Guards. The 2nd Battalion of the Irish Guards, raised at Warley, left England for France on the 17th August. Preparations on what was then considered an overwhelming scale, were under way to break the German line near Loos while the French attacked seriously in the Champagne country; the idea being to arrive at the long-dreamed-of battle of manœuvre in the plain of the Scheldt. Guns, gas-smoke apparatus, and material had been collected during the summer lull; existing communications had been more or less improved, though the necessity for feeder-railways was not at all realised, tanks were not yet created, and the proportion of machine-guns to infantry was rather below actual requirements. As compared with later years our armies were going into action with hammers and their bare hands across a breadth of densely occupied, tunnelled and elaborately fortified mining country where, as one writer observed “there is twice as much below ground as there is above.” Consequently, for the third or fourth time within a twelvemonth, England was to learn at the cost of scores of thousands of casualties that modern warfare, unlike private theatricals, does not “come right at the performance” unless there have been rehearsals.
