During the day the artillery attached to the 36th Division, to which the Potter Group, after having been in action under the 20th Division, had been returned, had actively barraged the roads leading south from the Canal de la Somme upon which the enemy was advancing. The Potter Group had bombarded the enemy massing for attack in the neighbourhood of the Esmery-Hallon--Golancourt Road, causing considerable casualties to parties in the open. The Erskine Group continued in action near Beines till French and British infantry had withdrawn through its guns. C/91st Battery remained covering the retirement till after dark, and was fortunate to be able to extricate its guns after the Germans were in Berlancourt. The Eley Group had to make three withdrawals, first, before noon, to Berlancourt; then, at 2-30 p.m., to Buchoire, where it covered the French infantry; and at 6 p.m. to the neighbourhood or Frétoy-le-Château. In every case the retirement was delayed till the last possible minute. The men of "C" and "D" Batteries, 153rd Brigade R.F.A., displayed the highest courage and most dogged perseverance throughout this day. At night the Erskine Group was put at the disposal of the 9th French Division, the Eley and Potter Groups at that of the 62nd French Division, under the control of the 36th Divisional Artillery Headquarters. General Brock, on return from leave, assumed command of the two latter Groups. Colonel H. C. Simpson, who had hitherto acted as C.R.A., became Liaison Officer with the 62nd French Division. An order of the 62nd French Division, issued at 2-15 a.m. on March the 25th, contained the following information and instructions for the 36th Division. The general line held ran west of Quesmy, Bethancourt, Fréniches, to the Canal de Robécourt at Rouy, east of Nesle. The _rôle_ of the 62nd Division was to check the enemy's advance, and prevent his crossing the Canal de Robécourt before, at earliest, the evening of the 25th. The British batteries were to remain in action under the orders of the 62nd French Division. The remaining troops of the 36th Division were to be withdrawn for reorganization, in readiness to assist the 62nd Division in case of emergency. The reorganization, such as it was, was carried out in the course of a fifteen-mile march. The 21st Brigade, now reduced to less than five hundred of all ranks, was ordered to rejoin its own Division north of Roye. It was detached from the line of retreat at Avricourt, where it was met by a column of 'buses. Officers and men saw it go, to the further desperate fighting which awaited its survivors, with sentiments of the warmest admiration. During the whole period of their attachment to the 36th Division, General Cochrane's men had displayed wonderful endurance and devotion. In the centre of a line which was turned upon both flanks, they had held each one of their successive positions till the last possible moment.
