The advance of the Battalion was led by C Company (Grimsdell) in two waves at 50 paces distance, followed by D Company (Cooper) in similar formation. B Company's rôle was to conform to the advance and protect the Brigade's right flank against any possible hostile action from the southern half of Bouleaux Wood, while A Company in reserve moved forward to occupy the positions vacated by the assaulting companies. The Battalion reached its objectives in the northern fringe of the Wood with little opposition, and with slight loss, killing a large number of Germans in the western edge of the Wood. A great many of the enemy were also put to flight, and these were caught on the open hillside on their way to Combles by the Lewis gunners of the Scottish advancing on our left, who did great execution among them. The consolidation of the strong posts allotted to the Battalion at once began, but was considerably interfered with by German snipers, who were still clinging to their posts farther south in the Wood. Under their fire Grimsdell (in charge of C Company) fell, shot through the head. This harassing fire rendered communication with Battalion Headquarters a matter of some difficulty, and continued through the night, as the 167th Brigade on the right had not been successful in pushing through the southern extremity of Bouleaux Wood. By nightfall the new posts were completed and occupied as follows: Post A--By 30 men and Lewis gun of C Company. Post B1--By 25 men of D Company. Post B2--By 30 men and 1 Lewis gun of D Company. These posts were improved and wired by parties from the Royal Engineers and the Cheshire Pioneers, while A Company subsequently constructed an additional post in the tram-line embankment north of the Wood. Meanwhile the London Scottish had been equally successful on our left, and had taken possession of the German trench running north-east from Bouleaux Wood in the direction of Morval; and farther still to the north the Guards Division had captured Lesbœufs, while the 5th Division were hammering at the western outskirts of Morval. The positions now occupied by the Brigade were of immense importance, as they secured excellent observation over the northern exits of Combles; and information received through the French from a German officer prisoner being to the effect that the Combles garrison was making preparations to fight its way out north-eastwards, the further operations of the Brigade were directed towards working round the north side of Combles and cutting off its communication with Morval. This scheme naturally affected the left flank of the Brigade more than the right flank, on which the Battalion was posted.
