The Commander-in-Chiefs plan was bold and simple, and promised great results. It depended for its success largely on the resolution and vigour with which the first part of the plan, the attack of Beersheba, was carried out. Owing to the waterless nature of the country, this place had to be in our hands within twenty-four hours from the commencement of the operations. If it were not, the troops would have to be withdrawn, owing to lack of water, the attack abandoned, and the operations commenced anew at some later date, against an enemy forewarned of our plans, and with the prospect of the winter rains putting a stop to our advance before it had well begun.
The operations as a whole divided themselves naturally into three main parts, in each of which the fighting would be of a totally different character. First, the attack and capture of the enemy's entrenched positions from Beersheba to the sea. This was primarily an infantry operation. Secondly, the pursuit of the enemy over the plain of Philistia, culminating in the capture of Junction Station, and the consequent isolation of any enemy force endeavouring to cover Jerusalem. This was to be the cavalry's opportunity. And lastly, the advance through the Judæan hills, and the capture of the Holy City.
For obvious reasons only the first part of these operations could be thought out in detail beforehand. The plan for this phase was as follows:--
1. To seize Beersheba and the high ground to the north and north-west of it, by a combined attack of cavalry and infantry, thus throwing open the left flank of the main enemy position at Hareira and Sharia. After the fall of Beersheba the cavalry would thus all be concentrated on the right flank of our forces, ready to pursue the enemy when driven from the remainder of his positions. The possession of Beersheba would, it was hoped, give us the necessary water to enable us to maintain our cavalry on this flank till the conclusion of the second phase of the attack.
2. To deliver the main infantry attack against the enemy's open left flank at Hareira, and endeavour to roll up his line from east to west.
3. In order to deceive the enemy up to the last moment as to the real point of our main attack, to pin him to his positions, and to draw reinforcements away from his left flank, an attack, preceded by a week's bombardment, was to be launched on the Gaza defences twenty-four to forty-eight hours previous to 2.
