Lieut.-Colonel J. V. Campbell, D.S.O., commanding supporting battalions, will be prepared to give such additional support as may be required to carry out the attack on the final objective――bearing in mind the necessity for holding positions already captured.
13. (_a_) At the first favourable opportunity after the Green line has been captured, O.C. Machine-gun Coy. will send one section forward to it. In this line and in his subsequent move to the Brown line two guns will always be on the right flank, ready to assist in the formation of a defensive flank.
(_b_) Similarly, when the Brown and Blue lines have been captured, one section will be sent forward to help in the consolidation of each of these lines.
Thus when the final objective has been captured there should be four guns in the Blue line and eight in reserve in the Brown line.
14. (_a_) Previous to the assault two guns will be established on the right of the Brigade area. These two guns will move forward at the first favourable opportunity and establish themselves on the right of the Green line.
(_b_) Two other guns will be in reserve in the front line, and will only move forward to the Green line if ordered to do so by Lieut.-Colonel J. V. Campbell, D.S.O., or by the Brigadier.
15. 75th Field Coy. R.E. and Work Platoons will move forward from their assembly area to the trench about T.8.b.3.0, as soon as this trench is clear of 3rd Bn. Coldstream Guards. They will be ready to move forward on receipt of orders from Brigade H.Q. and consolidate ground gained. O.C. 75th Field Coy. R.E. will detail one officer and three orderlies in liaison with O.C. supporting battalions.
16. When the Blue line has been gained, patrols will be sent forward, and any ground from which good observation can be gained will be occupied.
Such points will be consolidated and eventually joined up with our line.
17. One contact aeroplane will be in the air from zero till 6.30 P.M. on Z day. Flares will be lit by leading infantry lines on obtaining each objective and also at 6 _P.M._ on Z day.
18. Watches will be synchronised at 7 P.M. on Y day and at 9 A.M. on Z day.
19. Ammunition portions of first line Transport will be collected on the south-west side of Bernafay Wood to the south of the Guillemont――Montauban Road, and remainder of first line Transport in the neighbourhood of Minden Post by 12 noon on Z day.
