  • By Day. An Officer will always be at the Battery Observation Post from dawn to dusk.  He or the look-out man will watch the front visible from the Observation Post throughout that period.  If the Officer has to leave the Observation Post he must leave an N.C.O. in charge who knows exactly where the officer has gone.

Direct communication must always be maintained between the observation posts and their respective batteries and also the O.P. Exchange.

Batteries are responsible for the maintenance of all O.P. communications as far as panel points.

A Night O.P. will be manned by D/175 who will keep one Officer – One N.C.O. and two signallers from dusk to dawn at Sandbag Villa for the purpose of observing night movement-lights-rockets-gun flashes etc.


  1. GUARDS. Sentries will be kept on duty at each Battery Position by night and an aeroplane sentry by day. The night sentry must be acquainted with the nature of the S.O.S. rocket or other visual signal and be provided with a pointer which indicates clearly the zone covered by the Battery, and a gong for giving the Gas Alarm.




  1. BATTERY RETALIATION. In the event of minor enemy shelling of any portion of the Divisional Front the companies or company holding the portion shelled will if they wish for retaliation call on the Battery covering their front.


On receipt of call the Battery will shell German Front line opposite the portion of our trenches being shelled.  The Battery will fire 12 rounds.  If further retaliation is required reference will be made to Group Headquarters.


  1. GROUP RETALIATION. If the retaliation in para-10 is not sufficient the Battalion holding the front shelled may call on the Group stating the area shelled or the Group may act as it thinks fit.

Group Retaliation is according to Table A Appendix ii.


  1. COUNTER BOMBARDMENT SCHEME. The Counter Bombardment Scheme and maps are attached.




  1. LIAISON BARRAGES. Action by Right Group when

One 18-pdr Battery Barrage Enemy Front Line I.26.b.80.72. to I.21.c.22.05.


One Section 4.5” How. Battery bombard trench I.21.d.20.43. to I.21.d.22.28.


One Section 4.5” How. Battery bombard trench junction I.27.a.27.19.




  1. S.O.S. The Battery covering the trench from which the call emanates will immediately place a barrage at the rate of 4 rounds per gun per minute on “No Man’s Land” as close to our own trenches as safety permits. After two minutes this barrage will creep forward till it reaches the enemy front line where it will remain at the rate of two rounds per gun per minute till the situation is cleared up.

The Battery on either flank will open – but on the enemy’s front line parapet – at the rate of two rounds per gun per minute.  Further action will depend on the situation.

Howitzers are laid on special S.O.S. points and should the S.O.S. signal be sent up all along the line they will continue firing on these points otherwise they should be concentrated on the locality from which the signal emanates. The Art. will continue firing until word is received from Group H.Q. that the barrage is no longer required.

All Guns and howitzers will be laid on their S.O.S. lines by night and day. The S.O.S. signal or message will be passed from the battery receiving it to the battery on either flank and to Group Headquarters.  Group H.Q. will immediately inform Divisional H.Q. and the Group on their flanks.  Should Groups require assistance they will ask for it as per pre-arranged scheme – from the Groups on their flanks.


  1. GAS. Should the enemy launch a gas attack – the message will read “Gas Attack Trench ……”. All Howitzers should turn on to the enemy’s trenches from which the gas is being emitted or in which the enemy’s Infantry may be concentrated for the assault – and a light barrage by 18-pdrs of one round per gun per minute put in “No Man’s Land” to prevent hostile patrols following up the gas.       Should a subsequent message or S.O.S. signal be received the action of the Artillery will be as laid down for an ordinary S.O.S.


  1. HEAVY ART. Guns and Howitzers of the Heavy Artillery are laid on certain night lines and guns covering the sector attacked should – on receipt of S.O.S. message – open on their night lines; the remaining guns being employed for counter-battery work. If action is required over the whole Corps Front the Hows only will form the barrage – the guns being used for counter-battery work.


  1. AEROPLANES. The Right Group has the following selected squares allotted to it for work with aeroplanes.


D/175              I.

B/174               I.27.28.34.

Wireless Section at Right Group H.Q. I.1.c.10.62. Call X.


Aeroplanes – when practicing Zone Calls with batteries – will substitute a special prefix “D.D.” which will be followed by the co-ordinates of the points to be engaged. The call will be repeated at intervals of three minutes until the salvo is observed – after which the aeroplane will sent “C.I.” and a “mostly” correction.  Should the call not be answered after 5 repetitions of the same – the aeroplane will send “C.I.” and return.


The battery to which is allotted the square in which the point falls will open fire with one salvo as soon as they receive “L.L.” Call – and when waiting for the signal to fire from the aeroplane will fire a salvo as soon as possible after each repetition of the call until observation is received or until 5 salvoes have been fired.

The Zones are divided into three areas:




(see Table below)


(2) TIMES. During the first 6 hours the Red Area will be continuously bombarded by 3 guns per battery – 13 & 18 pdrs and 2 Hows and with interludes of short duration in which all guns will bombard the Red Area.

The other 3 guns will be kept on BLUE & BROWN Areas in short bombardments.


(3) Rate of Fire.  For first 6 hours – 1 round per gun per minute.

For remaining 18 hours – regulated according to circumstances (about 1 round per gun per 2½ minutes.)


  • TARGETS All Front Line System: Communication trenches: Roads Strong Points: Billets etc within the area are allotted to the respective batteries.

List of 4.5” How Targets attached.


Battery Tasks.  Battery Tasks submitted cover all targets mentioned and target tables are being made out for each gun.


AMMUNITION. Supply of ammunition is a difficult problem.  Dump allowances at gun pits should be increased in order to cover any length of daylight firing.


Ammunition required at gun pits for scheme during daylight.

For 13 & 18 pdrs per Battery 4000 (approx)

For How                                 3000
