The following was the situation at 6.30 P.M. The 60th Brigade held a line round the south and east of Arvillers. North-east of the village, on the main Roye--Amiens road, were elements of the 30th Division which had been driven out of Bouchoir. From this road to the left the 24th Division held a line which ran north-west and north of Bouchoir and then followed the road to Warvillers. The 59th Brigade was at Folies and the 61st at Beaufort. Hangest was held by the 61st Division and elements of the 30th, Le Quesnel by the 61st Division and the French. At midnight the enemy made a local attack on Folies, but this was very effectively repulsed by the 11th K.R.R.C., who inflicted a number of casualties and captured a machine gun. Before dawn on the 28th the 59th and 61st Brigades had been relieved by the 401st Regiment of the 133rd French Division. They marched along the main Roye--Amiens road to a wood south-east of Demuin, which they reached by mid-day. The relief of the 60th Brigade presented a good deal of difficulty, chiefly because the relieving troops belonged to two separate French formations. Before it could be completed, about 8.30 A.M. the enemy put down a heavy barrage, which he followed by an attack on the whole brigade front. After severe fighting, in which the enemy lost heavily, an advanced platoon of the 11th D.L.I. was driven in and the right flank of the battalion became exposed. A counter attack failed to restore the situation. The enemy then advanced on the front of the 6th K.S.L.I., and also worked round to the right of Arvillers. As it was evident that a serious attack was developing, Brig.-General Duncan ordered the brigade to withdraw. At this time the mixed troops on the right, who had occupied a ridge of great importance, and whose task was to hold on until the 60th Brigade began to leave the village, were seen to have fallen back. The position was then precarious. The enemy was only a few hundred yards away from the ridge, from which he could cut off the retreat of all troops from Arvillers. The situation was saved by the soldierly instincts and most gallant leading of Capt. Tait, the adjutant of the 12th R.B., who seeing what had happened, swung round a company of his battalion to the right, opened fire on the Germans at short range, and drove them off. At 11 A.M., under unusually heavy shell and machine-gun fire, the brigade withdrew in very good order, and at 3 P.M. rejoined the rest of the Division.
