About 9 p.m. further orders were received to withdraw to a ridge in the rear, in front of Cardigny. The movement was successfully carried out in the dark, and at dawn the new position was reconnoitred and the dispositions completed. At 7 a.m. the startling orders were received that the Fifth Army was about to withdraw to the west of the Somme, and detailed instructions as to the rearguard action were issued. The Battalion was to cover the retirement of the 5th Durham Light Infantry, which would in turn cover a further withdrawal. Accordingly the village of Cardigny was occupied with a view to a temporary stand. No sooner was this done than the enemy were on the outskirts and their snipers and machine guns were giving considerable trouble. The position soon became untenable, and permission was obtained to withdraw. This was done without loss, largely owing to the courage of Y Company, who, under Capt. J.F.G. Aubin, M.C., formed the rearguard to the Battalion. The next line of defence was a trench system on a ridge near Le Mesnil, which overlooked the Somme to the rear. Here things were quiet, though it was known that the enemy was working round the flanks, through Peronne on the left and Le Mesnil on the right. There was still a considerable amount of transport on the east of the river, and it was expected that a fight would follow to allow this to get away. After about two hours, however, orders came to cross the river by the Eterpigny footbridge. A route was taken across country towards this bridge, but there being no gap through the marshes and undergrowth, the Battalion was forced to turn aside through Le Mesnil village and, incidentally, to pass under a light shrapnel barrage. It was not known that the village was in the enemy's hands, but as soon as Z Company, who were leading, had reached the far side, the remaining Companies were attacked. Again Y Company distinguished itself, as did W and X Companies. They at once deployed, and though driven towards the marshes, successfully checked the enemy and eventually followed Z Company over the partially destroyed footbridge, about 300 yards long, with the loss of only two officers, Lieut. D.F. Charlton (killed) and 2nd Lieut. A. Dobson (prisoner), and about 20 men. For his action Capt. J.F.G. Aubin, M.C., was awarded the D.S.O. When all the Companies had been assembled on the west of the river a line was formed, along with the remnants of another Division, overlooking the marshes. By this time the day's fighting had died down, and things remained fairly quiet throughout the night.
