During the evening two patrols were despatched from New Woman Street to examine and report on the condition of the enemy's wire and front line trenches. They returned at 12.30 a.m. on the 28th, bringing samples of German wire, which was reported as too thick to admit of access to the front line. About the same time a rocket signal was sent up from the Bosche line, a red light followed by two more in quick succession, and this was the prelude to a sharp bombardment of our lines for about fifteen minutes. Somewhat later, about 3.45 a.m., a second barrage came down, this time on Hébuterne, but the damage caused was not great. As the day wore on the enemy's activity became less intense though he exhibited great persistence all day in his efforts to locate our batteries near Cross Street and our trench mortar emplacements in W 47. At night working parties were set on to the almost final preparation of cutting gaps in our own wire at intervals of about 50 to 70 yards to allow egress to the assaulting columns. This work is naturally rather tricky, and the gaps, the cutting of which was left till the last minute, must be so concealed if possible as to avoid the risk of the enemy marking them down and plastering them with shell fire. The day's casualties amounted to 2 officers, Lieut. W. A. Stark and J. W. Price wounded, and 2 men killed and 11 wounded. During the evening patrols had again been despatched to investigate the enemy's wire and trenches, and this night greater success was achieved. The right patrol which approached the Bosche line in front of Farm-Farmyard was under 2/Lieut. W. H. Webster, who on looking over the enemy's parapet found he had selected a firebay containing a party of Bosche hard at work. Unfortunately the alarm was given and the presence of the patrol being disclosed by Véry lights it was forced to withdraw. Late on the evening of the 29th the warning was received that the attack was postponed for forty-eight hours, until the 1st July.
