Haldane's Sixth Corps was to the immediate left of the Seventh, and its operations were directed due east of Arras. The three front divisions, counting from the south, were the Third, the Twelfth South of England, and the Fifteenth Scottish, with the Thirty-seventh English in reserve. The troops of the assaulting divisions had been assembled for three days in the caves under Arras, but on the night of April 8 they were silently passed into the assembly trenches, an operation which was carried through with little interference or loss. The vile weather may have been a blessing in disguise, as it covered all the preparations from the German observation.

The right of the attacking line was formed by the 76th Brigade of the Third Division, a unit which had distinguished itself greatly in previous fighting. The 8th and 9th Brigades were in close support. Its front was south of the Arras-Cambrai Road. To the left of the 76th Brigade the line was carried on by the 37th and 36th Brigades of the Twelfth Division. Their right rested on the Arras-Cambrai Road. To their left were the 44th and 45th of the Fifteenth Division. Their left rested upon the Scarpe. Nothing could have gone more smoothly than the advance, which kept well up with the barrage. Only at Observation Hill was vigorous resistance encountered, and the German barrage was so belated that it fell upon empty trenches after the stormers had left them. The line of infantry as it swept forward in its irresistible advance was formed, counting from the south, by the 10th Welsh Fusiliers, the 1st Gordons, the 6th Queen's, the 7th East Surreys, the 11th Middlesex, the 7th Sussex, the 8/10th[[1]] Gordons, the 9th Black Watch, the 6/7th Scots Fusiliers, and the 11th Argyll and Sutherlands. To the courage which had always been their birthright, the infantry now added all the cool war wisdom which experience of many battles must bring with it, and all those devices for overcoming the scattered forts of the enemy and avoiding their machine-guns, which had been learned on the Somme and the Ancre, were now practised to keep down the losses of the assault.

[[1]] Where two numbers are given for one battalion, it means that two battalions with these numbers have been telescoped into one.

The advance of the 76th Brigade had been to the south of the great high road which leads from Arras to Cambrai—a road which was destined to be second only to the Menin Road as a centre of hard fighting. The Gordons led the attack and took the front line with a number of the Prussian 38th Regiment. The 10th Welsh Fusiliers then passed through the ranks of the Highlanders and captured Devil's Wood. So swift were these movements that the German barrage was always in the rear. Having thus secured the first objective, the 9th Brigade, strengthened by the 2nd Suffolks, stormed forward to the next line of defence. The 4th Royal Fusiliers on the right took Nomeny, Spring, and Lynx Trenches, when the Suffolks passed through them and took Neuilly Trench. The 12th West Yorkshires took Tilloy village. The 13th Liverpool, after being held up on the left, carried the line forward and, by getting its machine-gun on to the roof of Tilloy Château, dominated the country to the extreme discomfort of the German snipers. Besides these numerous trenches and strong points, the 9th Brigade helped to take the fortified position known as The Harp, an exploit in which they were much assisted by a couple of tanks. Here a considerable number of prisoners were made, including most of a battalion of the 162nd Regiment, together with its commander.

It will save confusion if we follow the fortunes of each division for the day, regardless of what is going on upon its flank, as it is impossible to understand a narrative which switches continually from one portion of the line to another. The whole operation of the Sixth Corps was somewhat behind the time appointed, as each division had met with some delays, but the advance towards the third objective was begun about one o'clock in this southern area. The 8th Brigade had now taken up the running, and the 9th had fallen into support. Reinforced by the two reserve battalions of the 76th Brigade, the victorious advance was resumed, the 2nd Royal Scots and 7th Shropshires carrying the Bois des Boeufs to the south of the Cambrai Road, together with five guns which had been concealed in it. To those who had experienced what the capture of a wood meant in the Somme fighting, it was indeed a promise for the future that this considerable plantation should offer so slight a resistance. The 8th Brigade fought its way onwards for another mile or more until it had attained the line of Feuchy Chapel. Here the German resistance had thickened and the artillery fire had increased in the same ratio as the British had weakened. A halt was called, therefore, and the infantry consolidated their advanced position. An attempt by the Gordons and the 8th Royal Lancasters to reach the extreme final objective was checked in the evening by a very heavy fire upon both flanks.

In the centre, the Twelfth Division had met with strong resistance at several points, which caused the assault to fall behind the barrage. These centres of German resistance were usually isolated houses or small redoubts, so that it was possible in many cases to mask them and to push onwards. No village or large fixed defence lay in their path, and in spite of a check for some time at the estaminet upon the Cambrai Road, they were able to line up with their comrades to the south upon the second objective about half-past twelve o'clock. At this point the 35th Brigade passed through the advanced lines and moved to the front. A number of difficult positions were taken, including Observation Hill, and the ground was so thoroughly cleared that the assailants were able to go forward with the assurance that their wounds would not be in the back. It was found, however, as they neared the line of the third German position, that considerable stretches of wire had been imperfectly cut, and that the machine-gun fire was so severe as to make the final assault impossible. The infantry dug in, therefore, and waited for further support from the guns, many of which were already on the move. The 9th Essex upon the right actually reached the Feuchy Chapel Work and held their grip of it, keeping in line with the 8th Brigade upon the south.

The Fifteenth Division to the north of the corps' front had before them the very strong position called the Railway Triangle, where the line to Lens branches away from the line to Douai. This formidable place was attacked by the Scotch infantry, and after a severe struggle it was captured about 11.30 save for its eastern side, which was finally taken later in the morning, the artillery aiding the assailants by some extraordinarily good shooting. The advance was then resumed, and the division found itself shortly after noon in the line of the second objective. Six brigades of field artillery had followed closely upon the heels of the infantry and managed, in spite of the unfavourable state of the ground, to take up a position to cover the further attack. When one recalls the dreadful weather and the shell-pocked state of the countryside, it was a remarkable feat upon the part of the gun-teams to get their pieces so rapidly forward. Several tanks came forward also, and did good work not only upon this front, but at Tilloy and The Harp.

The Fifteenth Division was now somewhat behind the others, but shortly after two o'clock the 46th Lowland Brigade advanced upon the third objective. These splendid soldiers brushed aside every obstacle, and when fired upon at short range by German guns rushed onwards with a yell and captured the battery. By 4 P.M. they had fully reached their final line and had pushed out their patrols some hundreds of yards to the eastwards. This fine advance, which was the only one to reach the extreme limit upon this front, was carried out by the 7th Scots Borderers, 10th Scots Rifles, and 12th Highland Light Infantry, with the 10/11th Highland Light Infantry mopping up behind them.

At 7 P.M. an attempt was made by the two southern divisions to get forward from the Feuchy Chapel Line and gain a position level with the 46th Brigade. Evening was setting in, however, the men were weary and the difficulties manifold, so that no progress was made, both the Third and the Fourteenth Divisions suffering additional losses in the attempt.

The Thirty-seventh Division, composed entirely of English troops, North, South, and Midland, had moved up in the rear of the fighting line, and in the middle of the afternoon it found itself in the German second line system, while the corps' mounted troops had followed behind the Fifteenth Division, as far as the Railway Triangle. As evening fell, the Thirty-seventh Division pushed forward with the intention of reaching the extreme point attained by the Fifteenth Division and then swinging to the right in the hope of capturing Monchy. The advance seems, however, to have taken a direction rather too much to the south, with the result that instead of finding the opening made by the 46th Brigade they came upon the more contracted Feuchy line held by the Twelfth and Third Divisions. Here they were held up by a field of wire as their comrades had already been, and the two brigades concerned—the 111th upon the left and the 112th upon the right—remained in line with the 35th and the 8th Brigades, the units being considerably intermingled. The 63rd Brigade, however, which was now a brigade of the Thirty-seventh Division, though the reader will associate it with the Twenty-first Division in the past, was able to keep its true direction, and before night had finally established itself at the north end of Orange Hill well up to the third objective and in touch with the 46th Brigade. The corps' cavalry also pushed forward along the south bank of the Scarpe, capturing three 8-inch howitzers upon the way, and halting opposite Fampoux, where they were in touch with the Fourth Division upon the northern bank of the river.
