A very large attack had now been planned in which the First French Army, the Fourth, Third, and a portion of the First British Armies should all participate. The Germans were known to be tottering and one more good blow might bring them down. It was necessary to act at once, for the German delay-action mines, which were usually in the shape of one shell set to explode among a dump of shells by the road or railway, were making the communications almost impossible. Fortunately the ingenuity of the British sappers discovered the private mark—a small star upon the cap of the fuse—by which the danger-shell could be distinguished among its neighbours, and so many a disaster was averted. It should be mentioned that on October 30 two gallant senior officers of the gunners, Colonels Thorpe and Burnyeat, were both killed by the same shell.

The general line of advance of the Fourth Army, which had been north-east, was now changed to east. The orders given to the Thirteenth Corps were to advance in that direction, astride of the Sambre and Oise Canal, to the line of the Cartignies-Dompierre-Bavai Road. The Ninth Corps was to cross the Canal simultaneously on the right of the Thirteenth at Catillon and Ors, advancing on the same objective. The general proposition before the Thirteenth Corps was a total advance of about ten miles, part of it through the south end of Mormal Forest, with the forcing of the Canal crossings thrown in.

The frontage of the Corps attack was 7500 yards, narrowing down as it advanced, so three divisions were put into the line. On the right was the Twenty-fifth Division, with the task of forcing the passage of the Canal opposite Landrecies, of capturing that town, and of clearing the country up to Maroilles. The Sixty-sixth Division was then to carry on the advance to the ultimate objective.

The Fiftieth Division was in the centre and was to fight a way through Mormal Forest, while the Eighteenth Division on the left was to storm the village of Sassegnies. The desperate determination of the Army may be gauged from the fact that a large number of life-belts were served out to the leading brigade in case it should be necessary to swim the Canal for want of bridges.

The attack, the last great concerted movement of the war, was launched at 6.15 in the morning of November 4—a day of thick, all-pervading mist. The order of brigades from right to left in the initial advance was 75, 149, 150, 54, and 53. Good progress was made from the beginning all along the line, and the news from the Ninth Corps was uplifting. They were across south of Catillon and Ors, but the Thirty-second Division, on the immediate right of the Twenty-fifth Division, had been held up, so that they were ordered to move south and pass by the crossings already established. The Twenty-fifth and Fiftieth Divisions both got well away, the former at 9 A.M. being within 300 yards of Landrecies, while the latter was well up to the old bugbear, the Englefontaine-Landrecies Road, though Robinson's 149th Brigade, and especially the 13th Black Watch, had lost heavily. The Eighteenth Division had also attained its first objectives and drove off a half-hearted counter-attack. The 7th West Kents had a desperate house-to-house fight in the village of Hecq, which remained in their hands, while the 2nd Bedfords had a similar hard victory in Preux, where they were much helped by the 10th Essex.

The 75th Brigade had forced its way down to the Canal bank. The 5th Gloucesters had the good fortune to discover two German foot-bridges and poured across. It was indeed a proof of German deterioration that such an oversight should have occurred, for it is in attention to detail that the merit of German soldiering lies. The 8th Worcesters followed their comrades and these two battalions began to encircle the town from the south. There was no bridge higher up the Canal, but a fine feat of arms was performed by a small party of the 122nd Tunnelling Company, who dashed forward, seized the lock gates, and cut the wires which were meant to blow them up. On the extreme left some of the 1/8 Warwicks discovered another forgotten bridge and pushed across to the north of the town, which was now practically surrounded so that the garrison was soon taken or killed. The official report remarks: "The capture of Landrecies was an operation which might well have absorbed the energies of a whole division. Success was accomplished with a single brigade and was due to the spirited leading of the officers, the bravery of the troops, and that element of good fortune which any well-planned and boldly-executed enterprise deserves." The Eighteenth and Fiftieth Divisions had pushed on through the forest with hardly a check and surrounded a considerable number of Germans, who for the most part put up a very resolute resistance. About two o'clock there were signs, however, that the whole line was shaking, but it was impossible to advance farther until the Ninth Corps was in line. The final position on this most successful day was east of Landrecies, through Le Preseau, along the west bank of the Sambre to Hachette, and on to Locquignol.

Nov. 5.

It was guessed that the enemy was in a bad way, but on this evening it was confirmed by the capture of a cavalry orderly bearing a message ordering the troops to withdraw to the Sambre during the night, and to continue the retirement upon Maubeuge. Their skeleton rearguards still hung on, however, and put up a spirited resistance. Next morning, November 5, the corps advanced once more, the 74th Brigade taking La Rosière, while Maroilles fell before noon to the same division. The Eighteenth Division had pushed ahead and occupied Sassegnies, while the Fifth Corps were in Berlaimont on their left and were crossing the Sambre. The Fiftieth Division had more difficulty as the ground was very water-logged and the resistance considerable. The day's advance finished by the 74th Brigade, still in the van, capturing Basse Noyelle, while at dusk the 149th Brigade got across the Grande Helpe, a stream behind which the Germans were expected to build up a new line.

A steady advance was maintained next morning, November 6, though the constant tapping of machine-guns in front told of the German sporadic resistance. That night the line of the Thirteenth Corps was east of Marbaix and Dompierre. It was found that the small enclosed fields were very helpful in dealing with German machine-guns, as a concealed flank attack could always be carried out. Armoured cars on the roads were also found to be of great help to the infantry. On November 8 there was a sharp fight on the line of the Avesnes-Maubeuge Road. After the road was won there was a very spirited counter-attack, the German machine-gunners coming forward with great heart, though the infantry would not face the fire. The 6th Inniskilling Fusiliers and 1st Yorkshire Light Infantry bore the brunt of this engagement, which lasted several hours.
