No record in the 1/6th Battalion War Diary [WO/95/2694]
6/IX/17: Normal artillery and trench mortar activity. Hostile MGs quite at night but very active against our aeroplanes during the day. Its is noticeable that the German MGs are quite at night after a day during which there has been a large expenditure of ammunition in AA work.
