At 3.15 P.M. the enemy was turned out of a line known as Regiment Weg, which ran in rear of the Blue line opposite the 152nd Brigade front. Meanwhile the 154th Brigade had pushed on towards the Brown line, and were reported to have reached Tommy Trench at 1.40 P.M.
After the capture of the Regiment Weg, the 152nd Brigade were unable to continue their advance, as they were held up by Germans holding Elect Trench, which was situated about half-way between the Blue and Brown lines.
At 6.30 P.M. a message was received that the 154th Brigade had reached the Brown line, and were in touch with the Canadians at Commandant's House. At the same time the 34th Division reported that they were not in the Brown line. Orders were therefore issued for the 152nd Brigade and the 103rd Infantry Brigade of the 34th Division to assault the Brown line under cover of darkness.
The 5th Gordon Highlanders, who had been placed at the disposal of the 152nd Brigade, were detailed for this attack.
It was carried out at 5 A.M., and was a complete success. In conjunction with troops of the 103rd Brigade (34th Division), two companies of the 5th Gordon Highlanders advanced in a double wave, each rank being extended to ten paces. The attack was planned to be in the nature of a surprise, and was therefore not accompanied by an artillery barrage. The whole of the objective was captured. Some thirty dead Germans were found in the position, and fifty or more prisoners were captured in a redoubt known as the Maison de la Côté by the 103rd Brigade.
A curious situation now arose, as the 5th Gordon Highlanders on the Brown line could not get into touch on their left with the 154th Brigade. In fact, they were continuously being fired on with rifles and machine-guns from the Brown line to the north of them.
It subsequently transpired that the officer of the 154th Brigade who had reported that he was holding the Brown line was really in Tommy Trench, several hundred yards west of the Brown line, which was still occupied by the enemy on the 154th Brigade front.
General Hamilton therefore ordered the 7th Argyll and Sutherland Highlanders to initiate bombing attacks against each flank of the Brown line. These and subsequent attacks were, however, all held up by heavy machine-gun fire.
