12. As soon as the front and support lines are vacated by 2nd Bn. Grenadier Guards and 1st Bn. Irish Guards the 2nd Bn. Coldstream Guards and 3rd Bn. Coldstream Guards will occupy them.
All movement to these lines by supporting units should be by the communication trench from T.8.a.9.4 to T.8.c.3.8.
Similarly 2nd and 3rd Bns. Coldstream Guards will occupy the Green and Brown lines as soon as they are vacated by 2nd Bn. Grenadier Guards and 1st Bn. Irish Guards.
As soon as the 2nd Bn. Grenadier Guards and 1st Bn. Irish Guards have gained the Brown line, 2nd and
3rd Bns. Coldstream Guards will each send a company as clearing-up parties in Lesbœufs. These two companies must shelter in shell-holes behind the Brown line during the pause on that line. They must on no account be mixed up with 2nd Bn. Grenadier Guards and 1st Bn. Irish Guards. They will carry a special supply of P. bombs and Mills grenades for dealing with cellars.
The 2nd and 3rd Bns. Coldstream Guards are responsible for making good each objective as captured, and for guarding either flank if threatened, paying special attention to the right flank.
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.
Machine-guns—
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.
