The attack on the Yellow line, apart from the individual effort of the two companies of the 7th Gordon Highlanders, never took place. The fighting had been so severe that, by the time the leading troops reached the Green line, the barrage had been lost irretrievably. Moreover, the troops detailed for the capture of the Yellow line had been considerably involved in the fighting for the Green line, and were too reduced in number for an attack unsupported by an artillery barrage to have any chance of success. Later in the day orders were given for the 153rd Brigade to renew the attack on the Yellow line; they were, however, subsequently cancelled, as the Corps commander had decided to renew the attack on the following day. Towards the evening two companies of the 7th Argyll and Sutherland Highlanders were placed at General Burn's disposal. The two companies of the 6th Gordon Highlanders which had not as yet been employed were therefore ordered to march up the Beaumont Road at dusk and occupy and consolidate the Green line. The night was spent in consolidating and reorganising. At 2.30 A.M. on the night 13-14th orders were issued for the attack on Munich Trench to be resumed at 5.45 A.M., the remaining two companies of the 7th Argyll and Sutherland Highlanders and two companies of the 9th Royal Scots being placed at General Burn's disposal for the purpose. The headquarters and the remaining two companies of the 9th Royal Scots were placed at the disposal of General Campbell. During the night a telephone message, spoken over a faulty wire, was misunderstood, and the attack was cancelled instead of being postponed. When this error had been discovered, a fresh attack was initiated, in which the 7th Argyll and Sutherland Highlanders carried out a most successful bombing operation up Beaumont Alley and Leave Trench, and occupied Munich Trench. This attack, hastily improvised as it was, was admirably and gallantly executed, and was a complete success. Subsequently, however, the Argylls could not maintain themselves in their exposed position in a trench almost obliterated, and withdrew to Leave Alley. On the night of the 14th the 2/2 Highland Field Company, R.E., and one company of the 8th Royal Scots dug a new trench 150 yards west of Munich Trench. This trench was named New Munich Trench, and was occupied by a garrison before dawn. During daylight on the 14th, the 4th Gordon Highlanders took over the whole of the Green line on the 153rd Brigade front, the 6th Black Watch returning to Mailly-Maillet Wood. On the 152nd Brigade front the 6th Gordon Highlanders similarly took over the whole of the Green line, the 5th Seaforth Highlanders and the 8th Argyll and Sutherland Highlanders being withdrawn to Mailly-Maillet, and the 6th Seaforth Highlanders to the old British trench area.
