PATROLS.

It is considered that the Germans may possibly evacuate their front trenches altogether when our bombardment commences. Patrols, which go out to examine wire, will also try to enter the German trenches to discover if this is so. If the front line is found empty they should try to get into the close support line, but patrols must remember that the artillery will only be lifted off the portion of front which they are patrolling, for two hours at a time. They should therefore arrange to get back to “NO MAN’S LAND” at any rate, before the two hours is up. Careful arrangements should be made by means of tapes or any other suitable means for ensuring that patrols find their way back to our own lines quickly.

The Corps Commander does not wish any patrolling to be done by the 50th Brigade.

The 62nd Brigade will carry out the patrolling for the 50th Brigade on X/Y and Y/Z nights under arrangements to be made between the brigades concerned.

Orders have been received for the Division to be prepared to carry out the gas attack on the night U/V (24/25th June).

You will be informed by wire (Message “A”) shortly after 5 p.m. 24th June (and on each subsequent day as necessary) whether all preparations are to be made for the attack.

If preparations are ordered to proceed, definite orders will be received at a later hour from Div. H.Q. (Message “B”) as to whether gas is or is not to be discharged. This order (message “B”) will reach you in time to give very nearly two hours notice of the hour fixed as Zero for the gas attack.

The following order is issued for guidance:-
“It must be distinctly understood that when orders have been issued from Corps H.Q. for the gas attack to proceed, the officers of F. Coy. R.E. are responsible for deciding on the spot, from which emplacements it is not safe to discharge gas, and for suspending or delaying the discharge of gas in any part of the line where danger to our own men might result therefrom.”

Attention is drawn to Appendix “F”. Stokes Mortars will not take part.

It is impossible to say at what hour the warning telegram will be sent.

Messages from Division to Units concerned will be sent “Priority.”

62 Inf Bde must take steps to warn parties of other Brigades who may be working or carrying in the trenches.

Careful arrangements for the use of Vermoral Sprayers (if necessary) must be made.

Message “A” will consist of the words “ROGER” AAA Acknowledge.

Message “”B” will consist of “ROGER” 11 p.m. (or whatever time is ordered) AAA Acknowledge.

11 p.m. (or whatever time is ordered) in Message “B” will be the Zero time for the first discharge.

Acknowledge.

Reference 21 Div O.O. 55, Para 2 (b) (c).

A new German Trench has been dug as follows:-
QUADRANGLE Trench X.23.c.45.65. – Northern edge of BOTTOM WOOD X.29.a.1.8. – Southern edge BOTTOM WOOD X.28.b.91.27,, to RAILWAY ALLEY X.28.d.80.50.

In consequence the main second Objective of the 21st Division as given in above order is cancelled and the following substituted:-

Second Objective, 63rd Bde. X.29.b.5.6. (to connect with 7th Division) – thence along Northern edge of BOTTOM WOOD by Works 16/13 to new trench X.29.a.1.8. – along new trench to QUADRANGLE Trench X.23.c.4.5. (exclusive).

Second Objective, 64th Bde. Junction of new trench and QUADRANGLE Trench X.23.c.4.5. (inclusive) – along QUADRANGLE Trench to original Northern limit. Responsible for blocking QUADRANGLE Trench to the East.

The following advanced line will be occupied at once, and consolidated as soon as main Objective has been consolidated viz:-
63rd Bde.
X.29.b.5.6. – Work 17 QUADRANGLE WOOD to Work 18. X.23.d.05.48. (inclusive).
64th Bde.
Work 18, X.23.d.05.48 (exclusive) – QUADRANGLE Support Trench to connect with 34th Division at ACID DROP COPSE.

NOTE. This new main Objective has the following advantages:-
(a). New Trench and N. edge of BOTTOM WOOD for definite boundaries
(b). Work on the line can be carried out under cover afforded by the trench and Wood.
(c). The main line to be held is much more distinct from the advanced line than was formerly the case.
(d). The line does not form such a salient and hence is much stronger to hold.
(e). The task of 63rd Bde will be considerably simplified.
