We could batter their front line to bits, for, like our own, it was situated on lower ground, and consisted of breastwork parapets owing to the water-soaked state of the whole plain; but their infantry would retire to these deep dug-outs, only emerging when their sentries warned them of the lifting of our fire to permit the attack.

We could, and did, drive the enemy from his front line, and once there we held on, but that was as far as we could go, for each of these strong points presented a new and entirely different problem to attack, and required a separate bombardment.

Our offensive had started on May 9th and reached its height about the 16th, by which time we had won ground to an average depth of six hundred yards on a front of four miles.

At daybreak on the 16th the 7th Division attacked in the direction of the Rue D'Ouvert and Canteleux, and by 7 o'clock had entrenched themselves in a line running roughly north and south, half-way between their original trenches and La Quinque Rue. The remainder of the day and the following night were spent in consolidating this position and trying to drive the enemy from some short trenches and posts that prevented this division from linking up with the 2nd Division on its left. This was accomplished by noon of the 17th, and by nightfall further ground had been gained to the right. Slight advances were also made on the 18th, but bad weather had greatly hindered the operation of our artillery.

On the 19th, the 2nd and 7th Divisions, having suffered very severely, were withdrawn, the latter being relieved by the Canadians.

Part of the 3rd Canadian Brigade had already become involved and had taken part in an attack on La Quinque Rue, where they succeeded in advancing the line some five hundred yards and linking up this ground with the Wiltshires on their right and the Coldstreams on their left.

Further advance was held up by one of the enemy's strong points known as the "Orchard." This position was naturally strengthened by a deep ditch full of water on three sides, besides hedges and wire entanglements.

During the afternoon of the 19th the Orchard was heavily bombarded by our guns, the shelling continuing till 7.45 p.m., when the Canadian Scottish advanced to the assault, supported by the 13th Royal Highlanders of Canada. Simultaneously the 48th Toronto Highlanders attacked some hundred yards to the right of the Orchard.

These attacks were made in broad daylight, and, despite the torrent of fire with which the enemy opposed them, the objectives were quickly gained, though the casualties were most severe, and by night the new line was consolidated.

Meanwhile the 2nd Brigade, which had been occupying trenches to the right of the Orchard, had attempted to take a position known as the "Bexhill Redoubt," but with less success, as the preliminary bombardment had been quite ineffectual.
