'In the Ploegsteert (Belgium) Sector in the vicinity of Warneton, on the evening of 31st July/1st August 1917, it was reported that one of the Battalion advanced Posts had been heavily shelled and the telephone wires out; further, that another Post had also been heavily shelled with a good many casualties, including the two officers; no news was received from two other posts. To obtain information Lance Corporal Trembath was sent out about 10pm with instructions to visit all the Posts in our left sub sector, and obtain particulars. At the first post visited he found the NCO carrying on; he then, in spite of particularly heavy shelling, visited the next post, where garrison had, owing to its having been blown in, moved to a flank; and ascertained the names of the dead left in the Post. Next he went on to near the Sugar Refinery (Basse Ville) through further heavy shelling, and, aided by a man from a front line Post, brought in Pte 8/3333 McKellar, D.I. whom he found badly wounded. He then visited the last posts and returned. At about 1.30am the same night he led out ration parties to the Posts he had previously visited, and which, owing to the information he had brought back, were able to be reinforced at once. Throughout the night all the ground ever which Lance Corporal Trembath had to pass was shelled continuously by the enemy, and this NCO displayed great courage and devotion to duty in carrying out the work he did under such conditions, particularly when the condition of the ground, after heavy rain, is considerable.'
