On the 7th an inter-battalion relief was effected, the Battalion vacating the line in favour of the Kensingtons and Rangers who were respectively detailed as right and left assaulting battalions. The London Scottish moved to the old British line at Agny while the 1/4th Londons returned to dugouts in the railway cutting at Achicourt. The following day battle positions were occupied, the London Scottish moving forward to close support in rear of the Kensingtons, and the 1/4th Londons to Brigade reserve in the Circular Work. The Division's objectives for the 9th April were as follows: The 168th (left) and 167th (right) Brigades were to advance through Neuville-Vitasse to the first objective which was an arbitrary line (the Blue line) skirting the east edge of the village and facing the Hindenburg system. (_Note._--The Hindenburg line between Telegraph Hill and the Cojeul River was known as the Cojeul Switch.) This first phase was entrusted in the 168th to the Kensingtons and Rangers, the latter battalion on the left being prepared to adopt special measures and form a defensive flank facing north should the 14th Division be checked at Telegraph Hill. After a pause on this objective of about four and a half hours the London Scottish (168th) and 1st Londons (167th) were to "leapfrog" through the leading troops and carry the Cojeul Switch, the Scottish objectives being Back, Card and Telegraph Hill trenches (north of the Neuville-Vitasse-Wancourt Road). Here a further pause was to be made, after which the third phase of the battle would be taken up by the 167th Brigade, who would advance, covering the whole Divisional frontage on to the Wancourt line (Brown line). To return to the 1/4th Battalion. The day spent in Achicourt prior to manning battle positions produced the first serious German retaliation to our bombardment. As already remarked Achicourt was "stiff" with batteries and also contained a very extensive and important ammunition dump. Doubtless the Bosche decided that the quickest way to silence our guns was to destroy their supplies of shell, and from 11.30 a.m. until 5 p.m. he bombarded the village, causing a good many casualties in the Battalion and firing several houses which formed part of the dump. The village square, moreover, was packed with lorries loaded with shell waiting to move forward with the batteries, and unluckily the enemy obtained some direct hits on these. For some time the flying fragments rendered the place remarkably unhealthy. Excellent work was done in saving two lorries by Major H. Campbell of the Kensingtons. He well earned his D.S.O. by driving two of the blazing lorries out of the square into a place of safety. The battle positions occupied that night by the Battalion were as follows:
