On October 23 broke out the general engagement which will be known as the battle of the Oise-Sambre Canal. The order of battle of the Ninth Corps on this day was the First Division on the right, with the 2nd and 3rd Brigades in the line, and the Sixth Division on the left, with the 18th and 71st in the line. It was a night attack launched at 1 in the morning, and though a heavy German barrage, mixed with gas, beat upon it, none the less both divisions made good progress at first, though many obstinate strong points had to be reduced. By 8 {200} in the morning the First Division was reported as being on all its objectives from Catillon southwards, with patrols pushed into the town. The Sixth Division had great difficulty on its left flank while endeavouring to clear Bois l'Évêque, but late in the afternoon they got forward again. It was clear by night, however, that the Germans, who were battling hard, still held some parts of the west bank of the Canal, including Catillon and Ors. Next morning the Sixth Division, working in close liaison with the Twenty-fifth Division on the flank of Morland's Corps, got well forward, but were still short of their full objective on the left. Every day after this in a series of minor operations the Corps improved its footing on the west side of this great obstacle, which was of a most formidable nature, 60 feet wide, unfordable, with steep slippery banks and wire mixed with wooden abattis along the farther edge. Such was the new line of defence behind which the German Army had rallied, and which offered a fresh problem to the victorious British leaders. [Sidenote: Nov. 2.] Most of the western bank had been occupied by November 2, including the village of Ors, but there were points where deep marshes and German redoubts on this side had prevented the assailants from reaching the edge of the Canal. There was also a spur at the bend of the Canal which enfiladed the line, but this was taken as a preliminary operation by the Thirty-second Division. It was retaken, however, by the Germans in a very strong counter-attack supported by an overwhelming drum-fire. On November 3 the British again got the spur known as Happe-Garbes, but once again in the afternoon of the same day the Germans regained it in a very {201} determined advance. This heavy fighting fell upon the 96th Brigade and specially upon the 15th Lancashire Fusiliers, who were exposed to great pressure all day. Among many brave records that of Sergeant John Clarke of this battalion is pre-eminent, who took four machine-guns single-handed, bayoneting the crews, and fighting with desperate courage at the head of his platoon from morning till night. The idea of capturing the place before the general attack of November 4 was then given up, and other steps were taken to neutralise it. The main crossing of the Canal was planned to be at Ors, just south of Ors, and at two other points. [Sidenote: Nov. 4.]
