One of the most interesting features of the sector was a Russian sap, near the boundary between the centre and left companies. About 75 yards out in No Man’s Land, and nearly parallel to the left company front, was a bank, behind which patrols could move quite out of sight of the enemy. The remains of a derelict sap ran out to its southern end, but this had been replaced by a Russian sap--that is, a covered-in passage--well revetted with timber. A listening post was permanently established at the end of this sap; during the day it remained under cover, but at night it occupied a shell hole in the open. It was in touch with a second post, at the entrance to the sap, by means of a bell worked by a string. This apparatus was tested frequently to make sure that it was in working order. The existence of both listening post and sap was supposed to be unknown to the enemy; probably he knew all about them, but, at any rate, he was not supposed to. The front system, embracing both front and support lines, was divided into three company sectors. The fourth company was in battalion reserve. Battalion H.Q. was, of course, in its “correct” position, a little in rear of the reserve line. Companies did not always hold the same sectors, for the right was generally considered to be the most uncomfortable; but there was not much to choose between them. The F1 Sub-sector was the “liveliest” the Battalion held while it was with the Third Army, but it is not to be compared with such places as Thiepval Wood or Nieuport. Heavy artillery was not much used by the enemy, though the reserve company H.Q. had the reputation of being the datum point for 5.9’s. But the German field guns were very active on many parts of the front. The most frequently-shelled spot was the top of Forest Street--the communication trench on the extreme right. That point was constantly and very accurately “whizz-banged,” for the enemy could easily detect any movement there. All parts of the front line came in for attention. The enemy also used “rum-jars” and vane bombs very freely. The latter probably caused far more annoyance than casualties. However, Lieut.-Col. H. A. S. Stanton, D.S.O.,[8] was severely wounded by one of them. There was also a good deal of back area shelling, and the transport was harassed more than once on its nightly journey with rations. Near Basseux its route led through the position of a 6-inch howitzer battery, which the enemy frequently shelled. There Pte. H. Bibby, while driving a limber up to Riviére one night, had his ride horse killed under him. He coolly cut it out of the traces and completed his journey with one horse, himself walking by the side and supporting the pole for a distance of a mile and a half. It was not the first time that he had been brought to notice, and the award of a Military Medal, which followed, was well deserved.
