Their first destination was at Bray beneath the little hill above the Scarpe south of the long pavé to Villers-au-Bois, and their first duty was rehearsal for ceremonial parade on St. Valentine’s Day before their new corps commander. He complimented them on their looks and expressed his sense of the honour of having a Guards Brigade with him. After which came immediate conference on taking over the new ground assigned them, from troops of the Line. It was a sector of the line between Lens and Arras that had never shifted since the War was young—the Bailleul-Willerval stretch, about five miles north of their old sector at Fampoux, that ran up to Arleux-en-Gohelle and looked directly towards inaccessible Douai. It was worked on a different system from the old pattern—the brigade front of 2000 yards being lightly held by widely spaced fortified posts; with a strong support-trench known as the Arleux Loop a thousand yards in the rear. Their brigade went up in the night of the 17th, the 2nd Irish Guards in support. The enemy, quite aware there were new troops up, began to fish for samples. The 4th grenadiers held the front line on the 19th February. The C.O. of the 2nd Irish Guards had been up that afternoon to look at the lie of the land as the Battalion were going to take it over in a couple of days. Everything was quiet—too quiet to be healthy, indeed, till late in the evening when a heavy bombardment preluded a scientifically thought-out German raid for identification purposes. It failed, for the Grenadiers dealt rudely with the raids; but it lasted for a couple of hours from the time that the first SOS was sent up, and served the battalion, who stood to, but were not needed, as an excellent rehearsal for emergencies. Likewise, the enemy barrage knocked the front-line trenches about, and in the confusion of things an SOS went up from too far on the left of the assaulted line, so that our protective barrage came down where there was no enemy and had to be shifted. When the Battalion took over from the 4th Grenadiers (they could relieve all but two of the posts in daylight, thanks to the formation of the ground) Brigade Headquarters in its turn wanted samples from the German lines where had been recent reliefs. Nos. 1 and 2 Companies of the Battalion accordingly sent patrols unavailingly into No Man’s Land to see if they could catch any one. By the sheer luck of the Irish, an enemy deserter in full uniform must needs come and give himself up to our line in the afternoon. He was despatched at once to Brigade Headquarters with the single word: “Herewith.” The quarter-mile of chaos between the lines was so convenient that they used quiet nights to train their young officers and N.C.O.’s in patrolling; and as the brigades on their flanks were nearly half a mile away, the young also received much instruction in night-liaison work.
