On one occasion an enemy raid penetrated both our front and support lines without being detected or meeting anyone, and came upon our reserve line by chance at the only place on the front of the brigade concerned where there was one company in that line.

At another part of the front it was found, when normal conditions were restored, that in an abandoned part of our front line between two posts, the enemy had actually made himself so much at home that he had established a small dump of rations and bombs.
For the manner in which the Division had followed up and pressed the enemy withdrawal it received the thanks of the Commander-in-Chief.
On the 26th June 1917 the 46th Division was engaged on our right in active operations in the outskirts of Lens.

The 2nd Sherwood Foresters and the 9th Norfolk Regiment were placed at the disposal of the 46th Division for these operations.

The 9th Norfolk Regiment was not actively engaged, but the 2nd Sherwood Foresters, used in the later stages of the attack, fought with great gallantry and suffered fairly heavily.
On the 25th July the Division was relieved after a continuous tour in the Loos front of just under five months--a period of particularly bitter and severe trench warfare.

Trench-mortaring was continuous on both sides on the greater part of the front held, and shelling heavy.
The artillery suffered no less severely than the infantry, owing to the very restricted choice of positions and the advantages of the observation enjoyed by the enemy.
