- 9 batteries will be employed in wire-cutting on 3 front lines, each being allotted a front of about 200 yards.
The 4 remaining 18 pr batteries S of PERONNE Road will cut wire in GLATZ REDOUBT and DUBLIN trench.
- 4.5” Howitzers will bombard front and support line systems as laid down in attached Tables.
- The forward batteries will not open fire until the last day of the bombardment when they will register on support line trenches, GLATZ REDOUBT and DUBLIN Trench.

F Battery (9th Div,) L
- When GLATZ REDOUBT is taken and 90th Brigade are advancing a barrage will be formed by all 18 pr batteries along 8, 18 pr Batteries as detailed, along the S. & E. faces of MONTAUBAN and BERNAFAY Wood, lifting as Infantry approach on to W face of the Wood, and along the CATERPILLAR Valley. 7 Batteries will shell MONTAUBAN with H.E. F.O.O.s will be advanced to MONTAUBAN as soon as Infantry have occupied the village.
- The following will now be the arrangements for the support of the Infantry. The 90th Brigade will be supported by the Left Group, and a liaison officer and signallers will be sent forward with G.O.C. 90th Brigade by 150th Brigade R.F.A. The Right Group will support both 89th and 21st Bde and its Commander will have previously made arrangements for communication with 21st Brigade (para.2).
- The following batteries will be prepared to advance into positions N. of PERONNE Road ready to aid in resisting counter attacks:-
A/150 A.16. central
F (9th Div) A.15.b.3.3.
How Battery (9th Div) A.15.a.2.0.
These positions will be previously reconnoitered and prepared as far as possible, and the batteries concerned should have teams up handy by 0 + 1 hour.
- As soon as the GLATZ REDOUBT is taken the 151st Brigade will be prepared to send batteries or Sections in support of Infantry advanced parties sent forward to make good certain commanding points. Their teams should be up handy by 0 + 1 hour.
- As soon as MONTAUBAN is taken the whole or remainder of the 151st Brigade will be prepared to advance to positions near that village to give closer support.
- B/150 and A/148 will each have 4 teams and limbers ready to remove German guns should any be captured. These teams should be brought up to a handy position by 0 + 3 hours.
- During the period of wire-cutting and bombardment Group Commanders will detail batteries for night firing. These batteries will (1) Shell enemy’s communications to prevent him bringing up ammunition and supplies (2) By bursts of fire prevent the enemy from repairing his wire. Wire cutting batteries will by bursts of fire keep the enemy from repairing their wire at night, this will be done under group arrangements. Remaining batteries as detailed will shell enemy’s communications to prevent him bringing up ammunition & supplies. The arrangements for night-firing will be made in consultation with Infantry Commanders.
- During period preceding bombardment certain batteries will as far as possible be registered by aeroplane on various points N and E of MONTAUBAN.
- On X day there will be a discharge of Gas from midnight till 12-20 a.m. and again from 12-40 a.m. till 1.10 a.m. Each of these discharges will be accompanied by a heavy shrapnel barrage on 1st and 2nd line and communication trenches – the discharge to be preceded by 1 hour’s bombardment. On Y day there will be a discharge of Smoke from 3 to 3-30 a.m. When similar arrangements for a barrage and bombardment will be made. On certain days there will be discharges of gas & smoke, which will be accompanied by a heavy shrapnel barrage.
- Tables of tasks, times, and ammunition are attached. The times given for various ‘lifts’ are meant to indicate the times at which the Infantry willhave reached the lines or objectives in question. To ensure safety the lifts will be made 3 minutes before these times, e.g. the first lift will take place at 0.4 instead of 0.7. The times given for the various lifts, are the actual times at which batteries will lift their fire. When however observation is easy, and it can be plainly seen that Infantry are not within measurable distance of their objective it is open to Battery Commanders to postpone their lifts as long as they consider safe.
