The formation of the ground hid the opposing trenches from view—a factor of great importance, for it made the task of cutting the enemy wire a most difficult one for the artillery. The only point from which a little wire could be seen was close behind our front trenches. The F.O.O.’s and signallers had therefore to lay out and maintain very long telephone wires over fire-swept ground, which owing to the heavy rain of the last few days was little better than a morass. These difficulties were nevertheless overcome and the wire cutting was steadily carried out.
On the morning of the 7th patrols found that there was still wire in front of the German lines, so the guns again opened fire on it.
At zero—1.45 P.M.—the stationary barrage was put down, and at 1.47 it began to creep forward. In these two minutes three Stokes mortars with the 60th Brigade (the fourth had just been buried by a shell) fired 180 rounds on the German front line. The assaulting battalions moved forward close under the barrage with two companies in front and two in support, and with each company in two lines, thus forming four waves. With the fourth wave of each battalion were four machine guns from the 60th and 61st M.G. Companies.
The lending companies, advancing, according to a report from an officer in an observation post, “as though on Salisbury Plain,” came under heavy fire as soon as they reached the crest of the slope, which was about twenty yards short of the enemy wire. Some of the wire was still standing, at least on the front of the 60th Brigade, and for a short time held up the first two waves. The casualties here were heavy. Of the five company officers in the two leading companies of the 12th R.B., four were killed between this point and the wire, and one was severely wounded; of the rank and file about half were casualties. The 6th Oxford and Bucks L.I. suffered almost as much. Many of their losses were caused by a machine gun in a sap close to the wire. The third and fourth waves were following close behind, and as they came up they carried the first and second waves with them and together they captured Rainbow Trench. The 61st Brigade had less trouble with the enemy’s wire, but suffered from very severe rifle and machine-gun fire from the left flank, where a heavy barrage had prevented the 12th Division from reaching its objective. As the troops came up to Rainbow Trench the enemy surrendered in large numbers. At one point in the attack of the 61st Brigade the two opposing lines were seen to meet; then there was a moment’s pause, followed by the advance of our line and the return of a large number of prisoners. On the left of this brigade more resistance was met and a hand-to-hand fight ensued before the Germans—or such of them as were able to get away—were driven out of the position.
On the capture of the objective the first and second waves entered and held the trench, while the third and fourth formed up beyond it ready for the next advance.
When, at 2.5 P.M., the barrage again began to creep forward the attack was continued in three waves, the third being composed of the original first and second, less some machine guns and a few parties of men left behind to form posts in Rainbow Trench. The losses in this advance were comparatively slight, although the Germans, for the most part, remained in the position throwing bombs until the attacking lines were close upon them. Many of the enemy were killed at the second objective, which was captured about 2.15 P.M. Cloudy Trench was found to be little more than a line of disturbed earth, and all along the line the troops had to dig themselves in.
At the time the second objective was occupied the position of the flanks was a very dangerous one. The battalions in support had moved forward as the attack progressed, and had kept in touch with the leading units, but the divisions on the right and left had not captured their objectives, and so both flanks were in the air and under enfilade fire. Defensive flanks had therefore to be thrown back, leaving the Division occupying a pronounced salient. The heavy casualties in the Oxford and Bucks L.I. and the 12th R.B. have been mentioned; in the 61st Brigade also the leading battalions had suffered severely, especially in officers. The 12th King’s had only Capt. Milligan up in the second objective; the front line of the K.O.Y.L.I. was commanded by Lieut. Wright. Both these officers found their flank exposed, as there was a gap of three to four hundred yards between the two brigades, and they showed great initiative and judgment in siting their trenches and organising their defences so as to deal with any counter attacks that might develop. The situation on the left was especially difficult, as the troops were under a perfect hail of machine-gun and rifle fire, and casualties were becoming serious. The Somersets were called on for assistance and sent up two platoons under Sgt. W. E. Parker to strengthen the left flank, and a company to fill up the gap between the two brigades.
The enemy made several counter attacks in the course of the day, but all failed. Sgt. Parker was awarded the M.M. for his gallantry and good leadership in beating off one of these attacks. At 4 P.M. a company of the D.C.L.I. was sent as a further reinforcement to the left flank, arriving just in time to help to drive back a counter attack at this point. A working party of 200 men of the 11th R.B. came up to finish a communication trench in the 61st Brigade area, and to act as reinforcements if necessary. The 83rd and 84th Field Companies R.E. and 200 men of the 6th K.S.L.I. assisted the front line troops to consolidate their positions during the night; in spite of considerable casualties from the enemy’s heavy shell-fire this work was successfully completed. Behind the line a section of the 96th Field Company and three companies of the 11th D.L.I. dug a communication trench for the use of both brigades.
At 9 P.M. Brig.-General Banbury ordered Major Simcox, commanding the 7th D.C.L.I., to go forward with the rest of his battalion and take over and reorganise the front line system.
The casualties were 626 in the 60th Brigade, 469 in the 61st and 17 in the 59th. 192 prisoners, including five officers, and four machine guns and two mortars were taken.
