Into the variegated activities of that morning dropped a staff officer of the First Army Corps anxious to get the C.O.’s notes and instructions on mining for new troops who might later have to hold that line “in accordance with the manner taught by experience.” Captain J. H. T. Priestman of the Lincolnshires, a Sandhurst instructor, arrived with him and was attached to the sector for a few days “to see how things were carried on.” As he was being taken round the trenches by the C.O. and the Adjutant, next morning, a private, on sentry with a bomber, tried to throw a bomb on his own account, but, says the Diary, “not knowing how to, he blew himself up and wounded the bomber.” By breakfast time the enemy were shelling the line in enfilade from the direction of Auchy and two men were blown to pieces. A couple of hours later the bombardment was repeated with, from first to last, 6 killed and 9 wounded. The instructor was but one of many whose unregarded duty was to study at first hand every device of the enemy in action and to lecture upon it at the training-centres in England a few days later.
The Battalion relieved the Grenadiers once more on the 10th August, after another German mine had been exploded on the salient, and had carried away so much German wire that it seemed possible to effect an entry into their trenches across the new-made crater. A patrol under Lieutenant A. F. L. Gordon was therefore sent out at night but reported the slopes too steep to climb and, since another mine had gone up and destroyed four of our own sap-heads with it, the night was spent in repairing these under intermittent bomb-fire on both sides.
On the 11th August fresh attempts were made to work some sort of foothold across the crater-pitted ground into the enemy’s trenches, specially at the spot where a crater had been partially filled up by the explosion of a fresh mine. The day was quiet. Captain M. V. Gore-Langton spent the evening of it in reconnoitring the enemy’s wire, went out across the partly filled crater, found yet another crater which ran into the enemy’s line, and there met one German lying out within a few yards of him, whom Private Dempsey, his orderly, killed, thereby rousing the enemy in that particular point. They opened with bombs on a party of ours at work on a sap in one of the innumerable craters, and were discomfited for the moment. An hour later, Captain Gore-Langton, with one man, went out for the second time across the same crater to put up some more wire. He fell into the arms of a German bombing party, was knocked down thrice by explosions of bombs around him and only got back to the trenches with great difficulty. The C.O., Colonel Trefusis, then “remonstrated” with him on the grounds that “it is not the Company Commander’s business to go out wiring.” On the heels of this enterprise, a really vicious fight with machine-guns as well as bombs developed in the dark. It was silenced by four rounds of our howitzers when the roar of the bombs stopped as though by order. A third affair broke out just on dawn when our men found enemy working-parties in craters below them and bombed with them exceedingly, for the Germans were not good long-range throwers.
On the morning of the 12th August came General Horne to look at the position, which he examined leisurely from every part of the line instead of merely through the covered loop-holes which had been built for his convenience. “I was glad when I got him safely out of it,” wrote the C.O., “for one never knows when bombs may come over.” Just before they were relieved, the C.O., Colonel Trefusis, was telephoned word that he was to command the 20th Brigade and was pathetically grieved at his promotion. He hated leaving the Battalion which, after eleven months of better or worse, he had come to look upon as his own. No man could possibly wish to command a better. He was going to a brigade where he knew no one, and his hope was that he might be allowed to remain one day more with the Battalion “when it goes to the trenches” before going into reserve. He had his wish when they went into the line on the 14th August, and he faced the ordeal, worse than war, of saying good-bye to each company in the morning, and at evening “went round to make sure that the night companies had plenty of bombers in the proper places.” Bombs were the one tool at that time which could deal with nests of occupied craters, and since the work was dangerous the Irish were qualifying for it with zeal and interest, even though they occasionally dropped or released bombs by accident.
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.
