PRELIMINARY INSTRUCTIONS REGARDING COMMUNICATIONS
29TH DIVISIONAL ARTILLERY.
1. D.A. TO GROUPS.
Two phone lines to each Group and one sounder circuit to each Group are working at present. No change will be made.
2. GROUPS TO BATTERIES. (Ref. Attached diagram.)
(a) Right Group with H.Q. at MARIE JEAN FARM, will establish a forward exchange at B.12.c.5.3. (present H.Q. 5th Army Field Bde.).
Three Trunk lines, of which two will be ringing and one buzzer call, will be connected from Group H.Q. to this forward Exchange. These lines will be in the buried system as far as B.12.d.80.85.
Lines to Batteries will be laid overground from the Forward Exchange. Most of these lines already exist, and the general scheme should be similar to that shown on the diagram.
(b) Left Group with H.Q. at MARGUERITE FARM will establish a forward exchange at B.6.c.3.3. (present H.Q. of 75th Bde R.F.A.).
Three trunk lines (two ringing and one buzzer call) will be connected from Group H.Q. to this forward exchange. These lines will be in the buried system as far as L.H. test point B.12.a.2.6.
Lines to Batteries will be laid overground on the principle shown on attached diagram. Some of these lines already exist.
(c) In each case, the buzzer line from Group to Forward Exchange will be used for transmission of messages by Fullerphone.
Any message containing information which might be useful to the enemy will be sent on from Forward Exchange to Batteries by runner.
Communication between Group H.Q. and any battery in the group may be established, but orders applying to several, or all the batteries in the group should be sent to the Officer i/c Forward Exchange for transmission. This applies to S.O.S. originating at Group H.Q.
3. PERSONNEL AND MAINTENANCE.
All connections in the buried system and maintenance between Group H.Q. and their Forward Exchanges will be taken charge of by D.A. Signals.
Each group must arrange to provide telephonists for the Group H.Q. Exchange and their Forward Exchange. A sufficient number of linesmen must be posted at the Forward Exchange to maintain lines to batteries.
4. SEALED PACKETS.
A regular system of cyclist orderlies working between Group H.Q. and Forward Exchanges must be arranged. Between the forward exchanges and batteries, sealed packets will be carried by runner. A sufficient number of orderlies for this purpose will be required at each Forward Exchange.
For Motor Cyclist Despatch Rider runs, see attached list, which is subject to revision.
5. COMMUNICATION WITH INFANTRY.
Each Group will have a direct line to the Infantry Exchange C.B. (B.12.d.80.85) through which direct communication with SAULES FARM Infantry Bde H.Q. can be obtained.
6. COMMUNICATION WITH FLANK ARTILLERY.
Right Group Artillery will have a direct ringing phone line to Left Group. Right Divnl Artillery Communication will be arranged between the Left Group and the French Artillery on their flank.
7. LIAISON WITH INFANTRY BRIGADE.
Liaison between Artillery and Infantry will be carried out by the Brigade Commander stationed at LAPIN FARM. The Infantry Brigade at SAULES FARM will lay a direct line to LAPIN FARM, but the artillery signallers will assist in the maintenance.
