They do not seem to have been called upon to do more than sit, suffer and be shelled till evening, when they were relieved by a company of the 1st Coldstream and went back in the hard black frost to their bivouac in Gouzeaucourt Wood. Gauche Wood was won and held, but Gonnelieu, its houses and cellarages crammed with machine-guns, was a hopeless proposition from the first, to troops lacking tanks or adequate artillery aid. The sole excuse for attempting it was that the enemy’s pressure was heavy and increasing on all three sides of the Cambrai Salient (Bourlon Wood in the north was the point of most actual danger) and had to be met by whatever offered at the times and near the places. The 3rd Brigade was held up by the inevitable machine-gun in trenches in front of Gonnelieu and round the cemetery on its eastern outskirts; and there it stayed, under circumstances of extreme misery, till the 3rd December, when the 1st Brigade came back from Gouzeaucourt Wood to relieve. The 1st Irish Guards, numbering, then, four hundred and fifty battle-strength, who took over the 2nd Scots Guards’ and half the 1st Grenadiers’ line, were allotted what might be termed “mixed samples” of trench. No. 1 Company, for instance, held six hundred yards of superior wired line, evidently an old British reserve line, with the enemy dug in sixty yards away. No. 3 Company on its right had a section mostly battered to bits and, further weakened by an old communication-trench running up to the enemy, which had to be blocked as soon as possible. No. 2 Company was even less happily placed; for the enemy inhabited the actual continuation of their trench, so that they worked with their right flank grossly exposed. Two platoons of No. 4 Company lay close behind No. 2 to cover a gap; while the other two platoons in Flag Ravine, four or five hundred yards back, by the railway-line, were all the reserve the Battalion possessed east of Gouzeaucourt Wood. By some unexplained mercy of Providence that night, the next day and the next day’s night were “quiet” in the sense that there was no actual attack. The men sat in the trenches and froze; for the frost held day and night, and the enemy shelled the line at their will, with trench-mortars from near at hand and heavier stuff from the ridges beyond. Just before dawn, on the 5th December, they put down a very heavy mixed barrage behind the front line and a trench-mortar one on the line itself, and then attacked the two weak spots--No. 2 and No. 3 Companys’ position--with armoured bombers. The barricade to the communication-trench of No. 3 Company was blown in by a direct mortar-hit and a rush followed. No. 2 Company’s trench was also rushed end-on from the right, and three or four bays of it were taken. At this point, the Irish left the trenches all filling with the enemy, got out into the open, where for the moment there was no mortar-fire, and dealt with the invaders from outside, bombing and shooting downwards into the heavily-moving queues. The Germans wore their packs, “from which it may be inferred,” says the Diary delicately, “that they meant to occupy our trenches.” This, and their scientific armour, proved their undoing, and when--presumably to make doubly sure--an infantry attack swarmed out in two lines from Gonnelieu, it was broken up by our rifle and machine-gun fire, till it turned round and fled. Hereupon, says the Diary, “they were heavily bombed by their own side,” presumably as an example to His Majesty’s Guards of Prussian discipline. The casualties in the Battalion were one officer, 2nd Lieutenant Carey, and four other ranks killed; and about thirty wounded, mainly by bombs and mortars. But the affair was waste-work on both sides; for Gonnelieu was never taken by our arms. Our line here, in the next day or so, fell back on Gauche Wood; and of all the salient won at the Battle of Cambrai between the 20th and the 23rd of November, all that remained by the 7th of December was a stretch of country perhaps four thousand yards deep running from the Gouzeaucourt-Cambrai road to north of Demicourt. On the other hand, a cantle had been taken out of our old front line from opposite Vendhuille to Gonnelieu. But in the area that we held lay a sample of the great Hindenburg Line with its support-systems, its ten-foot-deep concreted and camouflaged trenches, covered gun-ways, machine-gun wells and shafts, and the whole detail of its immensely advertised impregnability. Men saw it with their own eyes, explored its recesses wonderingly, followed down the terrible lanes that the tanks had cut in its hundred-yard-deep beltings of wire, and settled themselves thankfully in its secure dug-outs, not foreseeing the days next spring when they would be swept out of it all like withered leaves.
