The 5th Seaforth Highlanders in the eastern outskirts of Roeux were attacked frontally, but defeated this attack by rifle and Lewis-gun fire. In the midst of this action they observed the enemy working round their flanks between the village and the river; the right section therefore faced its outer flank and stopped this movement by its fire, while the other neighbouring posts, after having disposed of the frontal attack, also faced half-right and strengthened the defence of this flank. In this manner a large number of Germans were accounted for. The resistance of the 5th Seaforth Highlanders in this corner was so effective that the enemy suddenly evacuated the whole area between Roeux and the river, and this portion of the line remained intact for the rest of the day. The enemy's effort on his left wing had therefore collapsed. On his right he was, however, more successful. He advanced on either side of the railway, firing Very lights across it so that the attacking forces hidden from each other's view by the embankment could keep in touch with each other. He occupied the foremost trench north of the railway, while south of the railway he continued his advance along the embankment. The area immediately south of the embankment should have been adequately covered by the machine-guns. These were, however, knocked out during the bombardment, and so could not play their part. To the north of the railway the enemy at once attempted to widen the area of his penetration by a series of heavy bombing attacks against the 6th Seaforth Highlanders, delivered from both flanks. The first of these attacks was successfully repulsed by Lieutenant Dow and his company, who, however, were compelled to use all their bombs in doing so. They therefore repulsed the second attack by advancing to meet the enemy with rifle and bayonet, these tactics completely discomfiting him. At 10 A.M. the enemy made a third and more determined attack. Lieutenant Dow was forced out of his front-line trench into a communication trench. Here he immediately organised a counter-attack, and led it in person against the enemy. The attack, however, failed, and Lieutenant Dow was mortally wounded. The gallantry and leadership of this officer had successfully limited the enemy's gains to a small footing in a section of the front-line trench. Farther to the north the second company of the 6th Seaforth Highlanders, under the command of Lieutenant King, had been skilfully disposed by this officer. This company was able to bring flanking fire to bear to support Lieutenant Dow against the enemy's attack, and in addition to defeat more than one frontal attack delivered against itself. Lieutenant King retained all the ground occupied by his company through the action.
