On the 3rd August the Division made a side slip to the left, our left sector now becoming our right; for the new left sector we took over the rather unpleasant piece of trench (the old Hindenburg line) which ran from due south of Riencourt to about 500 yards west of Bullecourt, and which included the latter village. On this readjustment the 35th Brigade, of the 7th Division, was added to my command, in positions in the Ecoust valley. I moved two batteries of the 312th Brigade across into the same valley, while A and C/312 remained on the Lagnicourt side temporarily. About this time we heard from a prisoner that part of the artillery acting against our front was the 49th Field Artillery Regiment; "but we call it," he said, "the 48½th, because they never quite reach their target, and are always firing into their own trenches." This was satisfactory hearing; at the same time we were uncomfortably aware that they managed to reach their targets rather more often than their own infantry seemed to suppose. Good news reached us on the 4th from the Ypres front of 6000 prisoners having been taken and St. Julien occupied. Operations had, however, been brought to a standstill in the north by the vile weather; really it seemed as though the elements were always on the side of the Powers of Darkness. Lieut. A. G. Bennett was wounded on the 8th August. On about this date one of my trench mortar batteries went into action in Bullecourt. They are in a ruin in the middle of the village. You get to them by first entering an old cellar in another ruin, and then scrambling down a sloping tunnel to an underground chamber about 30 feet below the surface of the ground. Here the detachment live. Then you crawl up another tunnel, and emerge into the ruin which holds the mortar emplacements.
