Just before 3 P.M. Brig.-General Duncan received orders from the Division to recapture Mézières in conjunction with the 59th Brigade. The 12th K.R.R.C. on the right and the 12th R.B. were ordered to attack the village from the south-west, while on the left the 11th D.L.I., with the 11th R.B. of the 59th Brigade on their right, worked through a wood on the north-west. About a company of the 2nd Scottish Rifles operated on the right of the 11th R.B. The artillery covering the Division was on the move, so that there were no guns to support this attack. Brig.-General Duncan and Brig.-General Hyslop asked such batteries as could be found in the neighbourhood to give their help, but very little artillery support was possible. Zero was fixed at 4 P.M. As the 12th R.B. received the orders at 3.45 P.M. and the 12th K.R.R.C. only at 3.55, these two battalions did fine work in carrying out their instructions and taking their place in the attack. They got right through the village, where they killed a large number of the enemy and took fifty prisoners. The 11th D.L.I., 10 officers and 130 men strong, came under a trench mortar barrage and enfilade machine-gun fire about 300 yards west of Mézières and lost heavily. Nevertheless the survivors worked their way forward. Lieut. King on the left got into the village and retired only when all his men had been hit. Capt. Pemberton with a small party succeeded in pushing right through, but as he had then only two men left, he also had to fall back. Another party entered the square and destroyed three German trench mortars which were found in position there. The 12th K.R.R.C. and the 12th R.B., however, were unable to hold the village, as they were caught in the rear by concealed parties of the enemy, who was also massing on their right front, and all battalions were forced to retire again. It appears that the Germans were attacking Villers at the same time as we attacked Mézières. Some of the prisoners captured stated that in their attack they had lost very heavily, and that three of their companies had been completely wiped out. The line was then established along the Demuin-Moreuil road. The 60th Brigade on the right had its right flank about the north-east corner of Cavalry Wood, where it was in touch with the French; the remnants of the 50th Division were placed under the 59th Brigade, which held the centre, with its left on the main road from Roye to Amiens; the 61st Brigade gradually fell back from positions south of Demuin during the night, and by the morning of the 30th continued the line from the left of the 59th Brigade along the road to the river Luce at Demuin. The 92nd Field Artillery Brigade came into action south of Hailles. About 11 A.M., as the troops north of the Luce retired towards Hangard, the 61st Brigade had to draw back its left flank to the west of Demuin.
