Chapter XXIII: Appendix: C

CORPS ORDERS FOR THE BATTLE OF AUGUST 8TH, 1918

The following were the complete orders issued by the Australian Army Corps for the Battle of August 8th, 1918. They form only a small part of the whole of the orders which were required for the operation. There were, in addition, detailed orders by the Corps Artillery Headquarters, the Heavy Artillery, the Chief Engineer, and each of the five Divisions and fifteen Brigades, and also by the Administrative Services of the Corps.

On the question of the form of the orders, the most expedient course was found to be the one here adopted--namely, that of issuing a numbered series of Battle Instructions, each dealing comprehensively with a separate subject matter:

BATTLE INSTRUCTIONS NO. 1

1. The Australian Corps will attack the enemy from the VILLERS-BRETONNEUX--CHAULNES Railway exclusive to the River SOMME, inclusive, at a date and hour to be notified.

The Canadian Corps will co-operate on the right, south of the railway (inclusive), and the Third Corps on the left, north of the SOMME.

2. _General Method of Attack._--The Australian Corps will attack on a two-division front. The attack will be carried out in three phases. Divisional boundaries and objectives are shown on the attached map.

(i) _First Phase._--The 2nd and 3rd Australian Divisions will form
up on a taped line prior to ZERO, and will attack with Tanks under
a creeping artillery barrage. Their objective is shown by a GREEN
line on the attached map.

On arrival at their objective they will consolidate.

(ii) _Second Phase._--The 5th and 4th Australian Divisions,
organized in brigade groups, will advance in open warfare
formations, from the first objective passing through 2nd and 3rd
Australian Divisions respectively. Their objective is shown in RED
on the map.

(iii) _Third Phase._--The 5th and 4th Australian Divisions will
exploit their success and seize the old British line of Defences
marked BLUE on the map, and establish themselves defensively on
this line.

(iv) The 1st Australian Division will be in Corps Reserve.

(v) A detailed programme of the action will be issued.

3. _Assembly._--In order to free as many troops from line duty as possible, 2nd and 3rd Australian Divisions will arrange to hold the front with one infantry brigade on each Divisional sector. This will be completed before daybreak on 5th August.

To prevent any troops arriving at their objectives in an exhausted condition through a long march, troops detailed to the farthest objectives must be quartered nearest the starting line prior to ZERO.

The brigades of 2nd and 3rd Australian Divisions not holding the line will be quartered in rear of all brigades of 5th and 4th Australian Divisions respectively prior to ZERO night. This will be completed before daybreak on 5th August.

The allotment of areas for quartering during this stage will be made by mutual arrangement between Divisional Commanders concerned. The allotment of routes and times of movement in accordance with the Corps programme will be arranged similarly.

On ZERO night the brigades of 2nd and 3rd Australian Divisions not in the line will make their approach march to their tape lines through the area occupied by 5th and 4th Australian Divisions respectively.

4. _Artillery._

(i) The Artillery available consists of:

18 Field Artillery Brigades.
12 Heavy Artillery Brigades.

(ii) G.O.C., R.A., Aust. Corps, will command all artillery of the
Corps during the first phase of the operation.

(iii) For the second phase G.O.C., R.A., Aust. Corps, will allot:

7. Deputy Director of Medical Services will arrange for the distribution of medical units.

BATTLE INSTRUCTIONS NO. 2

SECRECY

(_a_) It is of first importance that secrecy should be observed and the operation carried out as a surprise.

Commanders will take all possible steps to prevent the scope or date of the operation becoming known except to those taking part. Any officer, N.C.O., or man discussing the operation in public, or communicating details regarding it to any person, either soldier or civilian, not immediately concerned, will be severely dealt with.

(_b_) All movement of troops and transport will take place by night, whether in the forward or back areas of the Australian Corps, on and after 1st August, except where absolutely necessary to move by day.

(_c_) O.C., No. 3 Squadron, A.F.C., will arrange for aeroplanes to fly over the Australian Corps Army area during days when flying is possible, and to report to Corps H.Q. any abnormal movement of troops or transport within our lines.

(_d_) Work on back lines will be continued as at present, so that there may be no apparent change in our attitude.

(_e_) Commanders will ensure that the numbers of officers reconnoitring the enemy's positions is limited to those for whom such reconnaissance is essential.

Nothing attracts attention to an offensive more than a large number of officers with maps looking over the parapet and visiting Observation Posts.

Commanding Officers of units holding the front line should report at once to higher authority any disregard of these orders.

BATTLE INSTRUCTIONS NO. 5A

ASSEMBLY OF TANKS

_1. Preliminary Movement._

Tanks will be assembled in concealed positions in the forward area under the orders of the 5th Tank Brigade prior to night Y/Z.

_2. Advance to Start Line._

On night Y/Z the Tanks allotted to troops attacking the first objective will commence to move forward at 9.30 p.m. to the Tank Start Line. They will move with full engines to a line not nearer to the Tank Start Line than 3,000 yards. From there they will continue the movement forward to the Tank Start Line, moving at a slow rate and as quietly as possible. The Tank Start Line will be approximately 1,000 yards in rear of the Infantry taped line.

Tanks will leave the Tank Start Line at such times as will allow them to catch up to the Infantry as the barrage lifts at zero plus three minutes.

_3. Concealment of Engine Noise._

To conceal the noise of the engines during the advance of the Tanks, the 5th Brigade R.A.F. will arrange to have planes flying continuously over the Corps area from 9.30 p.m. until midnight on Y/Z night, and from zero minus one hour onward to zero.

_4. Tanks allotted to Second Objective._

The Tanks allotted to the second objective will form up independently under the orders of the 5th Tank Brigade in consultation with G.O.'s C., 4th and 5th Australian Divisions. These Tanks will be formed up when the aeroplanes are in the air during the hours laid down in para. 3.

_5. Liaison Company._

The company of the 8th Tank Battalion detailed to act in support, and to ensure liaison in the battle line at the junction of Divisions, will detail a half-company to each wave of Tanks, vide paras. 2 and 4 above.

Divisions will detail special liaison parties of Infantry to work in co-operation with this company.

_6. Re-assembly._

BATTLE INSTRUCTIONS NO. 6

ARTILLERY

_1. Preparation._

Active counter-battery work and harassing fire will be maintained.

Such registration as is necessary will be carried out under cover of this fire. A detailed programme for this will be arranged in each divisional sector.

The necessity for concealing the increase in the number of guns on the front must be borne in mind, and on no account should a large number of guns be employed at any one time. Counter preparation and S.O.S. plans during the period of preparation for the attack will be drawn up accordingly.

Normal fire should, so far as possible, be carried out from positions other than those in which batteries will be emplaced during the battle.

_2. Heavy Artillery._

(_a_) In view of the nature of the enemy's defences, the fire of
the majority of the heavy howitzers, employed for purposes other
than counter-battery work, will be used during the barrage to
engage special strong points or localities.

(_b_) Throughout the advance beyond the green line enemy centres of
resistance will be kept under fire until such time as the progress
of the Infantry renders this inadvisable. A map will be issued to
show the times at which heavy artillery fire will cease on zones
and special localities.

(_c_) At least two-thirds of the available Heavy Artillery will be
employed for counter-battery purposes.

Heavy concentrations of fire will be directed on the different
groups of enemy artillery.

3. G.O.C., R.A., will prepare plans for dealing with a heavy development of hostile fire on zero night. He will also prepare a plan to deal with any attempt at a deliberate gas bombardment of the VILLERS-BRETONNEUX area on zero night.

BATTLE INSTRUCTIONS NO. 7

PROGRAMME OF ACTION

_1. Capture of First Objective._

(_a_) Forming-up troops detailed to the capture of the first objective will be deployed on the Forming-up Line one hour before zero hour.

(_b_) _Artillery Programme._

(i) The field artillery 18-pdr. barrage will open at zero 200 yards
in advance of the forming-up line. At zero plus three minutes
the barrage will commence to advance; lifts will be 100 yards at
2-minute intervals. There will be two lifts at this rate.

The rate will then decrease to lifts of 100 yards every 3 minutes.
There will be eight lifts at this rate.

From the eleventh lift inclusive until the green line is reached
lifts will be of 100 yards each at 4-minute intervals.

(ii) The 4.5" Howitzer barrage will move 200 yards in advance of
the 18-pdr. barrage.

(iii) A protective barrage will be maintained in front of the green
line until zero plus four hours. During this period approximately
fifty per cent. (50%) of the guns remaining in the barrage will
be employed in a protective line barrage; the remainder will be
employed to search and sweep deeply into the enemy's position. At
zero plus four hours all barrage fire will cease.

Barrage Maps will be issued later.

_2. Capture of Second and Third Objectives._

(_a_) _Assembly._--5th and 4th Australian Divisions will select and mark positions for the assembly of their troops.

These areas will be selected in liaison with Tank Commanders and with the 2nd and 3rd Australian Divisions respectively, to prevent movement to them clashing with the approach march of these divisions and that of the Tanks.

This requires careful co-ordination between each pair of Divisions and Tank Commanders.

(_b_) _Command._--At zero plus four hours, responsibility for the battle front will pass to G.O.C., 5th Australian Division, in the right sector, and to G.O.C., 4th Australian Division, in the left sector.

(_c_) _The Advance._--5th and 4th Australian Divisions will time their advance so that the leading troops cross the first objective (green line) at zero plus four hours.

(_d_) From zero plus four hours the advance will be continued under the conditions of open warfare.

BATTLE INSTRUCTIONS NO. 8

ROADS

1. A map is forwarded herewith showing the organization of the road system in the captured territory.

2. The Chief Engineer will issue the necessary instructions for the preparation of these roads for traffic.

3. All light traffic which is capable of moving across country will do so and will avoid main roads.

4. Mule tracks will be a divisional responsibility.

5. Artillery advancing with the 5th and 4th Australian Divisions will carry forward a proportion of bridges. Arrangements should be made as soon as possible for the development of tracks, making use of the routes taken by the artillery over these bridges.

6. The AMIENS--LONGUEAU--VILLERS-BRETONNEUX main road, as far east as the cross roads in N.26.c., will be reserved for the exclusive use of the Cavalry Corps from 9.30 p.m. on Y/Z night until 8 a.m. on Z day. After 8 a.m. on Z day it will be available for the Australian and Cavalry Corps.

Assistant Provost Marshal, Australian Corps, will arrange for the control of the traffic on this road throughout.

Chief Engineer, Australian Corps, will prepare short avoiding roads at the cross roads at N.26.c. to cross the north-east or south-west corner to avoid congestion at this spot.

BATTLE INSTRUCTIONS NO. 9

LIGHT SIGNALS, MESSAGE ROCKETS, SMOKE

_1. Light Signals._

(_a_) _Australian Corps._

The following Light Signals will be employed in the Australian
Corps:

S.O.S. Signal, No. 32 grenade--showing green over green over green.
Allotment 500 per Division.

Success Signal, No. 32 grenade--showing white over white over
white. Allotment 600 per Division.

A small reserve of each of these grenades is held at Corps Headquarters.

No other Light Signals will be laid down by Corps. There is no objection to the use within Divisions of a Very Light for the local indication of targets between Infantry and Tanks.

(_b_) _Other Formations._

Light Signals of other formations are as follows:

_Formation._ _Signal._ _Meaning._

(i) Cavalry Corps. White star turning "Advanced troops
to red on a parachute of Cavalry are

green over green
over green.
No. 32 grenade, "Success signal,
white over white _i.e._, we have
over white. reached objective."
One white Very "Barrage is about
light. to lift."

(iii) Canadian Corps No. 32 grenade, "S.O.S." will also
red over red mean (_a_) "We are
over red. held up and cannot
advance without
help." (_b_) "Enemy
is counter-attacking."
No. 32 grenade, "(_a_) Lift your fire.
green over green We are going to
over green. advance. (_b_) Stop
firing."
Three white Very "We have reached
lights in quick this point."
succession.

_Remark._--In the case of (_a_) a smoke rocket (No. 27 grenade)
will also be fired in the direction of the obstruction to indicate
its position.

(_c_) Special care must be taken by the Artillery on the right
flank of the Corps that all officers and N.C.O.'s are acquainted
with these signals, so that no mistake may arise as regards the
difference in the S.O.S. Signals of the Australian and Canadian
Corps.

2. _Message-carrying Rockets._

Allotment of Message-carrying Rockets is 80 per Division.

3. _Smoke._

(_a_) Artillery smoke will be as follows:

(_i_) 3 rounds per gun will be fired during the first three minutes
of the artillery barrage.

(_ii_) 3 rounds per gun will be fired in quick succession on the
arrival of the field artillery barrage at the artillery halt line
covering the first objective.

(_iii_) In the event of wet weather a small proportion of smoke
will be used in the barrage to replace the smoke and dust caused by
the burst of the shells in dry weather. This will not be sufficient
to confuse the effect with that of the smoke shells prescribed in
paragraph 3 (_a_) (i) and (ii).

(_b_) _Screening beyond the First Objective._

15th Wing, Royal Air Force, will arrange to screen the advance of the Tanks and Infantry from special localities in advance of their first objective by dropping phosphorus bombs.

Divisions and G.O.C., 5th Tank Brigade, will inform Australian Corps Headquarters as early as possible of the localities which they desire screened.

A map will be issued showing times at which it is anticipated that the Infantry will make good certain zones. Phosphorus bombs will not be dropped within these zones at any time after it is anticipated that the Infantry will have occupied them.

BATTLE INSTRUCTIONS NO. 10

INTELLIGENCE AND DISPOSAL OF PRISONERS OF WAR

1. _Battalion Intelligence Police._

One German speaker and two searchers will be allotted to each battalion for use as follows:

(_a_) _German Speaker._

(i) To secure immediate identifications quickly, so that
identifications will reach Corps Headquarters as speedily as
possible of enemy units on the battle front.

(ii) To secure immediate information required by the Battalion
Commander as regards enemy dispositions, assembly positions, orders
for counter-attack, etc.

(iii) To be in charge of the two searchers and separate important
documents, orders, maps, etc., translate and convey information of
moment to the immediate Commander.

(_b_) _Two Searchers._

The two searchers under the German speaker systematically search the battlefield, enemy positions, suspected headquarters, dead, etc., for papers, documents, maps, etc., have them packed in sandbags, and sent through the usual channels to the Corps Cage as quickly as possible.

This personnel should carry torches and, besides rifles or revolvers, bombs are recommended as being useful for dealing with any of the enemy who may be found in dug-outs.

2. _Divisional Intelligence Officers._

Divisional Intelligence Officers will go forward to an Advanced Divisional Collecting Cage, with a view to obtaining, as soon as possible, information of immediate tactical importance.

The Cage will be connected by telephone to Divisional H.Q., and important information obtained should be transmitted as quickly as possible to Divisional and Brigade H.Q.

The main points on which immediate information is required from prisoners are: The Order of Battle, Units seen, Distribution of the Enemy's Forces, Method of holding the Line, Assembly Positions, Counter-attack Orders and Intentions.

This information will be wired to their respective Divisional Headquarters and repeated to Corps Headquarters and Corps Cage by Divisional Intelligence Officers.

Divisional Intelligence Officers will not detain prisoners longer than is necessary to obtain this tactical information of immediate importance.

In case a large number of prisoners are captured, they will detain only one or two from each regiment, and will not delay the passage of the remainder to the Corps Cage.

Any further information required from prisoners by Divisions or lower formations can always be obtained by telephone from the Corps Cage.

3. _Searching of Prisoners._

(_a_) _Officers and N.C.O.'s._

Officers and N.C.O.'s will be searched as soon as possible after
capture by a responsible officer or N.C.O., and all documents taken
from them sent back with them (in sacks, labelled by regiments, if
a number are captured) to the Divisional Intelligence Officer, at
such place as this officer has prearranged.

It is left to the discretion of Divisional Intelligence Officers as
to what documents, maps, etc., taken from prisoners they hold back
for the information of Brigade and Divisional Commanders. When this
is done, Corps "I" will be informed by wire, priority if necessary,
of the nature of the documents, etc., held back, and of any points
of immediate tactical importance they may contain.

As soon as possible after information has been extracted from them,
the documents will be forwarded on to the Corps Cage. Arrangements
can be made by Corps, if notified that documents are ready to be
sent on, to fetch them by motorcyclist or cycle.

(_b_) _Other Ranks._

Prisoners other than officers and N.C.O.'s will be searched on
their arrival at the Corps Cage. Their papers, etc., will be taken
from them and put into sacks labelled according to regiments.

(_c_) All ranks should understand that a prisoner's pay-book,
identity disc, and personal belongings should not be taken from
him. Escorts and guards will be warned to take special precautions
to prevent prisoners from destroying papers.

4. _Separation of Officers, N.C.O.'s and Men._

Care will be taken that officers, N.C.O.'s and privates are all separated from one another at once, and are not allowed to communicate with one another. Prisoners who have been interrogated should not be allowed to mix with those who have not yet been interrogated.

5. _Notification of Locality of Capture._

It is essential that, when prisoners are sent back, information be sent with them which will show where they were captured. Information as to the battalion which made the capture is a useful indication.

6. _Authorized Persons only to converse with Prisoners._

It is most important that no officer or N.C.O., except those duly authorized, be allowed to interrogate or converse with prisoners.

7. _Prisoners of War Cage._

The Advanced Corps Cage will be situated at VECQUEMONT, N.11.b.8.7. and the Rear Corps Cage at N.2.c.3.7.

Intelligence Officers and personnel will be stationed here, and will carry out a more detailed interrogation and sort out captured documents.

The Advanced Corps Cage will be connected by telephone to Corps H.Q.

8. _Prisoners._

The following procedure will be adopted for the disposal of prisoners:

After capture they will be escorted to the Advanced Divisional Collecting Cage, for examination by the Divisional Intelligence Officer, who, after he has finished with them, will send them back to the Advanced Corps Cage.

The sending back of prisoners should be carried out as quickly as possible, and several escorts should be arranged for them to be passed back without any unusual delay. Instructions should be issued to ensure that too many men are not employed on escort duty.

In the forward area directing notices should be placed to show the route to be taken to the Advanced Divisional Collecting Cage.

Traffic control personnel should be conversant with the method of disposing of prisoners.

9. _Identifications._

The importance of passing on all identifications as speedily as possible to Corps "I" cannot be too strongly impressed on all concerned. It is essential that special efforts be made to wire at once, as soon as identifications are made and the locality in which obtained.

10._ Maps and Photographs._

The following maps are being issued:

(i) A large issue of 1/20,000 No. 62.D. South-East regular series
for distribution to all officers.

(ii) 1/20,000 Map Message Form, for distribution down to N.C.O.'s.

BATTLE INSTRUCTIONS NO. 11

CO-OPERATION OF INFANTRY AND AIRCRAFT

1. _Contact Aeroplanes._

(i) _Indication of position by flares._

(_a_) Red ground flares will be used to indicate the infantry
positions to contact aeroplanes. They will be lit by infantry in
the most advanced line only.

(_b_) A contact aeroplane will fly along the line of the first
objective at zero plus 2 hours 30 minutes. Flares will be called
for by the aeroplane sounding a succession of "A's" on the Klaxon
horn and by firing a white Very Light. If the aeroplane fails to
mark the line accurately, it will repeat its call ten minutes later.

Should the infantry not have reached the line of the objective at
the time laid down above, the contact aeroplane will return at
half-hour intervals until flares are shown.

(_c_) A contact aeroplane will fly along the line of the second
objective at zero plus 6 hours 30 minutes. It will call for flares,
and the same procedure will be followed on this objective as on the
first objective until the flares are seen.

(_d_) A contact aeroplane will fly over third objective at zero
plus 7 hours, when the procedure laid down for the first objective
will be observed until the flares are shown.

(_e_) Divisions will organize message-dropping stations in the
vicinity of their Headquarters.

(ii) _Other means of identifying the position of the Infantry._

(_a_) _Rifles._--Three or four rifles laid parallel across the top
of the trench.

(_b_) _Metal Discs._--Metal discs will be used as reflectors by
flashing in the sun. This method has been successful even on days
which have not been particularly bright.

The disc is most easily carried sewn to the Small Box Respirator,
and can be used in this way without inconvenience.

2. _Counter-attack Planes._

(_a_) From zero hour counter-attack planes will be constantly in
the air, with the object of observing hostile concentrations or
abnormal movement.

(_b_) In the event of an enemy concentration indicating a
counter-attack, the counter-attack aeroplane will signal this
information to the Artillery by wireless. In the case of a
counter-attack actually developing a white parachute flare will be
fired by the aeroplane in the direction of the troops moving for
the impending counter-attack, for the information of the Infantry.

3. _Ammunition-carrying Aeroplanes._

(_a_) Aeroplanes will be detailed to transport ammunition from zero
plus 2 hours 30 minutes.

(_b_) Vickers guns will display a white "V" at the point where
ammunition is to be dropped. The arms of the "V" to be 6 feet in
length and 1 foot in width. The apex of the "V" to point towards
the enemy.

(_c_) Ammunition aeroplanes will have the under-side of the lower
planes painted black for a distance of 2½ feet from the tips.

BATTLE INSTRUCTIONS NO. 12

CONSOLIDATION

1. _Divisions allotted to First Objective._

(_a_) _Consolidation._--As soon as the first objective has been captured troops will dig in.

(_b_) _Troops holding present front line._--The brigades of 2nd and 3rd Australian Divisions holding the line on the night prior to zero will remain in their battle positions until all troops detailed to the attack have passed through. They will then be organized and prepared to move to meet any emergency.

2nd Australian Division will be prepared to detach its brigade to act in support of 5th Australian Division, and 3rd Australian Division to detach its brigade in support of 4th Australian Division.

(_c_) _Reorganization of Troops on First Objective._--As soon as the whole of the troops detailed to the capture of second (red line) and third (blue line) objectives have passed through the line of the first objective, 2nd and 3rd Australian Divisions will organize the defence of their sectors on the first objective in depth in each brigade sub-sector. Units will be reorganized, and those not detailed to the defence of the line will be withdrawn into support and held in readiness for eventualities. At least one battalion in each brigade sub-sector should be withdrawn in this way.

2. _Second Objective._

_Consolidation._--As soon as the second objective (the red line) has been captured, the position will be thoroughly consolidated. Arrangements will be made to ensure a supply of engineering material for this.

3. _Main Line of Resistance._

(_a_) When the third objective (the blue line) is attained, it will be organized and consolidated as the main line of resistance.

(_b_) If the enemy is able to develop an immediate counter-attack, or if he has a definite plan, and the troops available in close reserve for the defence of the blue line, it may not be possible to reach the third objective. In this case the second objective (red line) will become the main line of resistance, and will be consolidated and organized in depth accordingly.

(_c_) Definite plans will be prepared to deal with either case. The Corps must be prepared, as early as possible, to fight a stiff defensive battle on the main line of resistance.
