Extract from the official war diary of 1st Bn, 22nd (Cheshire) Regiment
Weather was fine and at 10.25 a.m. a bombardment of the German lines was started by our Trench Mortars, in retaliation for German bombardment of the 7th inst. This was followed by Artillery fire which continued until 6.30 p.m. The French heavy artillery fired again and also our 15 in. (2 rounds) and 12” (19 rounds). The NEW ZEALAND R.E. exploded 3 camouflets about 12 noon. Enemy retaliated against the Trench Mortars at once, but remained quiet for the remainder of the day. The night passed very quietly.
