On the 7th of June the very successful battle of Messines gained the whole of the southern part of the ridge as far as a point about a mile south of Hooge. The object of the operations which began at the end of July was to extend this success and to push forward our lines east and north of Ypres so as to embrace the whole of the high ground which at present dominated our position in the salient. On the front of the XIVth Corps this meant an advance north-east, of which the first stage was to be the capture of Pilckem Ridge and the ground as far as the Steenbeek.

The Divisional Artillery covered the right sector of the XIVth Corps front, occupied till the beginning of July by the 29th Division, and after that by the 38th. The line, which extended from a point opposite Krupp Farm to the canal bank just short of the railway, was little changed since the 20th Division had held it in the spring of 1916. It had been pushed forward and straightened at certain points, and to the left of this sector the British had taken over a further stretch of 1500 yards along the canal, but the general situation of the trenches remained the same.

The conditions, on the other hand, had been very greatly improved. Many miles of new tram lines had been laid, so that nearly every battery had a line running to within a hundred yards of the gun positions, and a large number of ammunition dumps had been formed. The flatness of the country made it impossible to get complete flash cover for all guns. Camouflage screens, however, had been erected all along the front, and with the natural cover afforded by numerous small copses and farms, most batteries were able to obtain fair flash cover.

The Divisional Artillery had to occupy entirely new positions; these were reconnoitred on the 13th; work was begun on them that night, and on the 14th, 15th and 16th the batteries came into action and took their part in the preliminary bombardment.

The divisions detailed to carry out the attack in the XIVth Corps were the 38th on the right and the Guards on the left; the 29th Division was in reserve behind the Guards, and the 20th was to arrive in this area in time to come into reserve behind the 38th.

The bombardment continued throughout the rest of July, for the operations originally planned to begin on the 25th were put off till the 31st. A marked feature of this period was the silence of the German guns by day, a great contrast to the continual shelling of 1916. This was the result of the very thorough counter-battery work which had been carried out in the salient by the heavy artillery, assisted by our aeroplanes. It is known that the Germans withdrew their guns by day and brought them up each night, when they shelled the whole area heavily, especially with gas. They had been engaged, when the 20th Divisional Artillery came into the line, in moving back their battery positions across the Steenbeek, and the increased activity which they showed after the 21st of July pointed to the completion of this manœuvre.

The enemy’s night firing, by killing and wounding many of the drivers and horses as well as by continually breaking the Decauville railway, made the supply of ammunition exceedingly difficult, especially for the Divisional Ammunition Column, which was working day and night forming dumps in the forward area for future operations. There were considerable losses, too, among the gunners; B/92 Battery had 24 casualties in two nights, and on the 22nd had to be withdrawn from the line for a short rest. The 93rd (Army) Brigade was in the most forward position, and it had been decided to keep this as a silent brigade. Owing to the casualties incurred in the Divisional Artillery, this plan had to be abandoned on the 22nd in order to keep up the programme of night firing that had been laid down.

With the exception of a few raids on the enemy’s lines, the only operation carried out before the battle began took place on the 27th, when information was received that the enemy had retired from his front line. Strong patrols sent out to verify this report crossed No Man’s Land unopposed, entered the enemy’s front line, and even pushed on beyond it. Later they met with strong resistance from numbers of the enemy concealed in large concrete dug-outs, and when reinforcements came up from the direction of Pilckem, the patrols were forced back to the original line. Prisoners stated that the enemy was much shaken by our bombardment, but had no intention of retiring on this front. Opposite Boesinghe, however, the enemy did retire, leaving in our hands both banks of the Yser Canal, which had formed till then a serious obstacle to the advance of the Allied left flank.

During this time the Divisional Ammunition Column worked very hard and earned the congratulations of the C.R.A. Between the 19th and the 26th the column delivered over 35,000 rounds to the batteries, besides sending out rations, water, and large quantities of camouflage and material. In the latter half of July the casualties in the column were 3 officers, 37 other ranks, and 113 animals.

Meanwhile the Division had entrained at Domart on the 20th of July and concentrated in the XIVth Corps area, with headquarters at Proven. For the rest of the month it remained in Corps reserve behind the 38th Division.
