Dawson was in a serious quandary. He had his line intact, except for the single point of Gauche Wood, which was an outpost of his forward zone; but with the enemy on Chapel Hill not only was the whole forward zone turned, but the first part of the battle zone, for this eminence commanded all the trench system in what was known as the Yellow Line. The front had now a singular formation, running back sharply from the extreme point of Quentin Redoubt in the north-east, by the west side of Gauche Wood to the north side of Chapel Hill, which itself was in the area of the 21st Division. The two forward battalions of the South Africans, the 1st and the 2nd, were most gravely menaced. After midday came worse news, for the enemy was reported to be as far west as Genin Well Copse. At all costs it was necessary to recapture Chapel Hill,[26] so “A” Company of the 2nd Regiment, which had been reserved for a counter-attack, was sent early in the afternoon to strengthen the right flank. They found the Germans holding the trenches on the north ridge of the hill, and could make no further progress. Meantime the 4th Regiment, which, as we have seen, was manning the battle zone, was able to bring flanking fire to bear on the Germans at Genin Well Copse, and this, aided by a detachment of machine gunners at Revelon Farm, stayed further enemy progress on the south. At 3.30 the 2nd Regiment reported that the Germans were concentrating in large numbers south-west of Vaucellette Farm for a further attack. It was difficult to check them with artillery, for the guns of the Brigade at the time were covering not only their own front, but 600 yards of that of the 21st Division. At half-past five Lieutenant-Colonel MacLeod, commanding the 4th Regiment, was ordered to send a company to retake Chapel Hill. “A” Company, under Captain Bunce, was detailed for the purpose, and by a spirited counter-attack they took the crest as well as the trenches on the south and south-east slopes, and so enabled posts to be established linking up the ridge with Genin Well Copse.
