There can be no better ill.u.s.tration of how one battle worked out 'according to plan' than the quotation of the following Force Order:

FORCE ORDER

GENERAL HEADQUARTERS, _22nd October_ 1917.

It is the intention of the Commander-in-Chief to take the offensive against the enemy at Gaza and at Beersheba, and when Beersheba is in our hands to make an enveloping attack on the enemy's left flank in the direction of Sheria and Hareira.

On Zero day XXth Corps with the 10th Division and Imperial Camel Brigade attached and the Desert Mounted Corps less one Mounted Division and the Imperial Camel Brigade will attack the enemy at Beersheba with the object of gaining possession of that place by nightfall.

As soon as Beersheba is in our hands and the necessary arrangements have been made for the restoration of the Beersheba water supply, XXth Corps and Desert Mounted Corps complete will move rapidly forward to attack the left of the enemy's main position with the object of driving him out of Sheria and Hareira and enveloping the left flank of his army. XXth Corps will move against the enemy's defences south of Sheria, first of all against the Kauwukah line and then against Sheria and the Hareira defences.

Desert Mounted Corps calling up the Mounted Division left in general reserve during the Beersheba operation will move north of the XXth Corps to gain possession of Nejile and of any water supplies between that place and the right of XXth Corps and will be prepared to operate vigorously against and round the enemy's left flank if he should throw it back to oppose the advance of the XXth Corps.

On a date to be subsequently determined and which will probably be after the occupation of Beersheba and 24 to 48 hours before the attack of XXth Corps on the Kauwukah line, the XXIst Corps will attack the south-west defences of Gaza with the object of capturing the enemy's front-line system from Umbrella Hill to Sheikh Hasan, both inclusive.

The Royal Navy will co-operate with the XXIst Corps in the attack on Gaza and in any subsequent operations that may be undertaken by XXIst Corps.

On Z--4 day the G.O.C. XXIst Corps will open a systematic bombardment of the Gaza defences, increasing in volume from Z--1 day to Zx2 day and to be continued until Zx4 day at the least.

The Royal Navy will co-operate as follows: On Z--1 and Zero days two 6-inch monitors will be available for bombardment from the sea, special objective Sheikh Hasan.

On Zero day a third 6-inch monitor will be available so that two of these ships may be constantly in action while one replenishes ammunition. On Zxl day 6-inch monitors will discontinue their bombardment which they will reopen on Zx2 day. From Zxl day the French battleship _Requin_ and H.M.S. _Raglan_ will bombard Deir Sineid station and junction for Huj, the roads and railway bridges and camps on the wadi Hesi and the neighbourhood. The _Requin_ and _Raglan_ will be a.s.sisted by a seaplane carrier.

From Zero day one 92 monitor will be available from dawn, special objective Sheikh Redwan.

From Z--1 day inclusive demands for naval co-operation will be conveyed direct from G.O.C. XXIst Corps to the Senior Naval Officer, Marine View, who will arrange for the transmission of the demands so made.

XXth Corps will move into position during the night of Z-l=Zero day so as to attack the enemy at Beersheba on Zero day south of the wadi Saba with two divisions while covering his flank and the construction of the railway east of Sh.e.l.lal with one division on the high ground overlooking the wadis El Sufi and Hanafish. The objective of XXth Corps will be the enemy's works west and south-west of Beersheba as far as the Khalasa-Beersheba road inclusive.

Desert Mounted Corps will move on the night of Z-1=Zero day from the area of concentration about Khalasa and Asluj so as to co-operate with XXth Corps by attacking Beersheba with two divisions and one mounted brigade.

The objective of Desert Mounted Corps will be the enemy's defences from south-east to the north-east of Beersheba and the town of Beersheba itself.

The G.O.C. Desert Mounted Corps will endeavour to turn the enemy's left with a view to breaking down his resistance at Beersheba as quickly as possible. With this in view the main weight of his force will be directed against Beersheba from the east and north-east. As soon as the enemy's resistance shows signs of weakening the G.O.C.

Desert Mounted Corps will be prepared to act with the utmost vigour against his retreating troops so as to prevent their escape, or at least to drive them well beyond the high ground immediately overlooking the town from the north. He will also be prepared to push troops rapidly into Beersheba in order to protect from danger any wells and plant connected with the water supply not damaged by the enemy before Beersheba is entered.

The Yeomanry Mounted Division will pa.s.s from the command of the G.O.C. XXth Corps at five on Zero day and will come directly under General Headquarters as part of the general reserve in the hands of the Commander-in-Chief.

When Beersheba has been taken the G.O.C. XXth Corps will push forward covering troops to the high ground north of the town to protect it from any counter movement on the part of the enemy. He will also put in hand the restoration of the water supply in Beersheba. The G.O.C. Desert Mounted Corps will be responsible for the protection of the town from the north-east and east.

As soon as possible after the taking of Beersheba the G.O.C. Desert Mounted Corps will report to G.H.Q. on the water supplies in the wells and wadis east of Beersheba and especially along the wadi Saba and the Beersheba-Tel-el-Nulah road. If insufficient water is found to exist in this area G.O.C. Desert Mounted Corps will send back such of his troops as may be necessary to watering places from which he started or which may be found in the country east of the Khalasa-Beersheba road during the operations.

A preliminary survey having been made, the G.O.C. XXth Corps will report by wire to G.H.Q. on the condition of the wells and water supply generally in Beersheba and on any water supplies found west and north-west of that place.

He will telegraph an estimate as soon as it can be made of the time required to place the Beersheba water supply in working order.

When the situation as regards water at Beersheba has become clear so that the movement of XXth Corps and Desert Mounted Corps against the left flank of the enemy's main position can be arranged, the G.O.C. XXIst Corps will be ordered to attack the enemy's defences south-west of Gaza in time for this operation to be carried out prior to the attack of XXth Corps on the Kauwukah line of works.

The objective of XXIst Corps will be the defences of Gaza from Umbrella Hill inclusive to the sea about Sheikh Hasan.

Instructions in regard to the following have been issued separate to all corps:

Amount of corps artillery allotted.

Amount of ammunition put on corps charge prior to operations.

Amount of ammunition per gun that will be delivered daily at respective railheads and the day of commencement.

Amount of transport allotted for forward supply from railheads.

The general average for one day's firing has been calculated on the following basis:

Field and mountain guns and mountain howitzers ...150 rounds per gun.

4.5-inch howitzers....120 rounds per gun.

60-pounders and 6-inch howitzers. 90 rounds per gun.

8-inch howitzers and 6-inch Mark VII. 60 rounds per gun.

This average expenditure will only be possible in the XXIst Corps up to Zx16 day and for the Desert Mounted Corps and XXth Corps to Zx13. After these dates if the average has been expended the daily average will have to drop to the basis of 100 rounds per 18-pounder per day and other natures in proportion.

AIRCRAFT, ARMY WING.--Strategical reconnaissance including the reconnaissance of areas beyond the tactical zone and in which the enemy's main reserves are located, also distant photography and aerial offensive, will be carried out by an Army squadron under instructions issued direct from G.H.Q. Protection from hostile aircraft will be the main duty of the Army fighting squadron. A bombing squadron will be held in readiness for any aerial offensive which the situation may render desirable.

CORPS SQUADRONS.--Two Corps squadrons will undertake artillery co-operation, contact patrols, and tactical reconnaissance for the Corps to which they are attached. In the case of the Desert Mounted Corps one flight from the Corps squadron attached to XXth Corps will be responsible for the above work. Photography of trench areas will normally be carried out daily by the Army Wing.
