By 3 A.M. on the 13th Colonel Fleming had organised his force into two sectors, the right being commanded by Major Campbell of the 6th Black Watch, and the left by Major Stein, 4th Gordon Highlanders. The night of the 13th passed quietly, and was employed by Colonel Fleming in advancing his line by 700 yards and in reorganising his force. The railway companies and some elements of the Berkshire Regiment, who had become attached to the Division, were withdrawn. Their place in the line was taken by the 7th Gordon Highlanders, who had by this time been collected and reorganised. The remnants of the 152nd and 153rd Brigades were also collected and formed into a composite battalion under Lieut.-Colonel J. M. Scott, D.S.O., commanding the 5th Seaforth Highlanders. On 14th April orders were issued for the 154th Brigade to relieve Fleming's Force during the coming evening. Shortly before this relief took place the 4th Division, which had recently arrived in the area, attacked northwards from the canal bank and established themselves on a line from the canal through Riez-du-Vinage to Carvin. Thus when at 2 A.M. the relief of Fleming's Force was completed, the actual firing line was for the most part well to the east of the line actually held by the 154th Brigade. The situation then remained unchanged until the night of 23-24th April, when the 154th Brigade was withdrawn. Throughout this engagement the 4th Seaforth Highlanders had been attached to the 55th Division, and had taken part in the obstinate and successful defence of the defensive flank which that Division had formed from Givenchy to Le Touret. On the morning of the 9th April the 4th Seaforth Highlanders had been in billets at the Ferme du Roi near Bethune, in close proximity to the 55th Divisional front. In consequence, when the sudden break through the Portuguese lines occurred, they were placed under the orders of the 166th Infantry Brigade under the command of General Kentish. Their first move was to the banks of the Canal de Lawe. Later, during the same day, it was discovered that a gap existed in the line held by the 166th Infantry Brigade, north of Le Touret. The battalion was therefore moved forward under cover of darkness and disposed so as to fill this gap, their headquarters being established at Les Faucons. During the day (10th April) the enemy did not attack in force, but he made several local attempts to penetrate the line held by the 4th Seaforth Highlanders. On each occasion he was repulsed, and the position was maintained intact throughout.
