Reserve at disposal of Brigades (e) Immediately the objectives are reached Bdes will push forward patrols to establish under cover of these patrols a line in touch with Divs on the Right and Left as near as possible to the German positions.
(f) For the capture of the 3rd objective 2 bns of the 61st Inf Bde in reserve will be available to be placed at the disposal of 59th and 47th Bdes if required (para 11) but these Bdes will make their preparations for capturing the 3rd objective without having to call on the reserve.
(g) It may be necessary to employ the two rear battalions of the Divisional Reserve for the final objective, but this will depend on whether the 59th and 47th Brigades have used the two Reserve Battalions from the Divisional Reserve to gain the 3rd objective.
Bombardment 8. (a) The attack will be preceded by a bombardment by heavy artillery, commencing at 8 a.m. on morning of September 2nd.
(b) During this bombardment certain trenches may have to be cleared from time to time and arrangements for this will be made between XIV Corps H. A. and 20th Division.
Barrages (c) Fifty per cent of the Field Artillery guns in the division will be employed for stationary barrages and 50 per cent for rolling barrages.
Details of the stationary barrages are shewn on the attached map marked “B”.
(d) At Zero an intense Field Artillery barrage will open on the first objective. This barrage will lift as shewn on the attached map marked ”B”. At the same hour a creeping barrage will be opened one hundred yards in front of the infantry and will advance at the rate of fifty yards per minute in front of the infantry until the objective is reached. When this barrage has passed 200 yards beyond the objective it will become stationary.
Whenever the creeping barrage reaches the stationary barrage, the stationary barrage will lift on to the next barrage line, i.e. the next colour in front of it on the map.
An intensive rate will be continued for fifteen minutes when fire will drop to two rounds a minute per gun.
The barrage on BROMPTON ROAD, objective of Left Battalion, Left Brigade, will lift at ZERO 4 in stead of ZERO 3. the remainder of the barrage will lift at ZERO 3 as ordered.
(e)At the hour of Zero, all heavy howitzers will lift from GUILLEMONT.
Six inch howitzers will continue on the objectives in GUILLEMONT, east of GREEN STREET, HILL STREET and the German trench line from T.25.a.8.7½. to WEDGE WOOD.
(f) At Zero plus 50 the Field Artillery barrage will again become intensive and the infantry will advance to their 2nd objective, and the same procedure as ordered in para. (d) will again be followed.
An intensive rate will be continued for fifteen minutes, when fire will drop to two rounds a minute per gun.
(g) The heavy howitzers and six inch howitzers will, after zero plus 50, not fire on any parts of the third objective except the CEMETERY, and WEDGE WOOD – GUILLEMONT Road, between T.26.a.1.1. and T.20.a.1.5.
(h) At zero plus two hours the Field Artillery barrage will again become intensive and the infantry will advance to the third objective.
- The barrage on WEDGE WOOD – GINCHY Road in front of 20th Division will lift at 2 hours 15 minutes and not at 2 hours 25 minutes as shewn on Map ”B”.
An intense rate of fire will be maintained for 25 minutes.
(j) To enable the 4th attack to be made the barrage will again become intensive at Zero plus 2 hours 45 minutes. The creeping barrage will advance at the rate of 50 yards per minute until it has passed 200 yards beyond its final objective.
(k) Detailed orders for the action of the Field Artillery will be issued by the C.R.A. 24th Division (attached to 20th Division).
The movements of the Infantry will conform to the rolling barrages, it being essential that they get up close under the barrage and move along under it.
Pusher mine etc. 9 A “pusher” mine under the strong point at S.30.b.7.1. will be exploded at 0 – 10 seconds and the Flammenwerfer will open fire at the same hour if in position. The front trench will be cleared for 20 yards on either side of SCOTTISH LANE.

The two Bns. will be prepared to carry out the attack on the 3rd objective from the 2nd objective at 0 2 hours, for which purpose one bn would be placed at disposal of G.O.C. 59th and G.O.C. 47th Inf. Bdes. Respectively.
The G.O.C. 61st Inf. Brigade will keep in close touch with the 59th and 47th Infantry Brigades and will be prepared to act on his own initiative failing communication with Divisional Headquarters.
Note. ADD. Within the boundaries of GUILLEMONT Village creeping barrages will advance at the rate of 100 yards per 4 minutes.
(a) The 60th Inf. Bde. will not move forward from the CRATERS until ordered to do so by Divisional Headquarters.

Flares will be lit as follows:-
(a) On attaining each objective.
(b) At 7 p.m. September 3rd.

The contact aeroplanes may be recognised by their markings of two long blue streamers, one attached to the end of each plane, and two transverse black bands on the plane, one near each end of the coloured circles.
