Immediately before my left flank lay the Méricourt bend on the south of the river and the Etinehem bend to the north of it. Both were held by the enemy, doubtless fugitives from the great battle, who had sought food, water and underground shelter in the numerous dug-outs which honeycombed the sides of the valley. The design was to capture the whole of these with little effort. It was a good plan, and only an unforeseen accident prevented its full realization.

Early on the morning of the 10th, I summoned a conference at Maclagan's Headquarters in Corbie, which was attended by the Commanders and certain Brigadiers of the Third and Fourth Divisions. It was arranged that on the north of the river, the 13th Brigade would that night get astride of the Etinehem spur on the north, while simultaneously the 10th Brigade, by making a side sweep skirting Proyart, would advance our line till its left rested on the river a mile east of Méricourt.

Columns were to move along defined routes, leaving the objectives well to the flanks, and then to encircle the enemy positions. Each column was to be accompanied by Tanks and was to move in an easterly direction and then wheel in towards the Somme. Although Tanks had never previously been used at night, as their utility was uncertain, it was thought that the effect of the noise they made would lead to the speedy collapse of the defence.

The plan succeeded to perfection on the north of the river, and the Etinehem spur and village with all its defenders fell to us almost without a blow. Four Tanks amused themselves by racing up and down the main Corbie—Bray road at top speed, and the clamour they made cleared the path for the marching infantry.

On the south, however, just after nightfall, a sudden onslaught by a flight of enemy bombing planes, threw the head of the 10th Brigade column into confusion, and its Commander was killed. Two of the Tanks were also disabled by direct hits from Artillery. This delayed the progress of the operation, and the next day broke with the task uncompleted. The 9th and 11th Brigades were, however, at once sent up to reinforce, and during the following day all three Brigades completed the operation by possessing themselves of the villages of Méricourt and Proyart and the woods adjoining the river.

This series of local operations yielded some 300 prisoners, and entirely cleared up the confused and unsatisfactory situation which had existed on my left flank, as the aftermath of the Chipilly spur failure of the first day. It also brought my line up more square to the Somme, and so somewhat shortened my already expanding front. But my left flank was at last quite secure.

I must now turn to the extreme right flank, which was, on this same day, also the scene of very severe fighting. I have related the progress of the First Division to the foot of the Lihons ridge the night before. On August 10th and 11th the advance was continued by the First and Second Divisions in sympathy with the advance of the Canadian Corps on the south of the railway. There were only a few Tanks left available to assist in this advance; and the resistance of the enemy in the neighbourhood of Lihons had stiffened considerably.

The devastated area had already been reached by us in this part of the field, and the terrain was a labyrinth of old trenches, and a sea of shell-holes; the remains of old wire entanglements spread in every direction, and the whole area had been covered by a rank growth of thistles and brambles. It furnished numerous harbours for machine-guns, and it was country over which it was difficult to preserve the semblance of an organized battle formation during an advance.

The enemy fought hard and determinedly to retain Lihons, and in some parts of the line the battle swayed to and fro. But before the morning was well advanced, we had taken possession of the whole of the Lihons Knoll, of Auger Wood, and of the villages of Lihons and Rainecourt, while the Canadians had passed through Chilly just south of the railway. All that afternoon the enemy made repeated counter-attacks, particularly directed against Lihons and Rainecourt; but they were all successfully driven off by rifle and machine-gun fire without the loss of any ground.
