Your subsequent moves will depend on circumstances which cannot at present be gauged, but it is hoped that the remainder of your force will be available on the morning of the 7th August to advance on Biyuk Anafarta with the object of moving up the eastern spurs of Hill 305 so as to assist General Birdwood's attack.
7. The operations from within the present Anzac position will begin during the day immediately preceding your disembarkation (the reinforcements for General Birdwood's force having been dribbled ashore in detachments at Anzac Cove on the three previous nights). The operations will begin with a determined attack on the Turkish left centre, Lonesome Pine and Johnston's Jolly (see enlarged map of Anzac position), with the object of attracting the enemy's reserves to this portion of the line. The Turks have for long been apprehensive of our landing in the neighbourhood of Gaba Tepe, and it is hoped that an attack in force in this quarter will confirm their apprehensions. At nightfall the Turkish outposts on the extreme right of the enemy's line will be rushed, and a force of 20,000 men will advance in three or more columns up the ravines running down from Chunuk Bair. This advance, which will begin about the same time as your first troops reach the shore, will be so timed as to reach the summit of the main ridge near Chunuk Bair about 2.30 a.m. (soon after moon-rise).
Latest photographs show that the Turkish trenches on this ridge do not extend further north than Chunuk Bair, and it is unlikely that the higher portions of the ridge are held in great strength.
As soon as a lodgement has been effected on this ridge a portion of the attacking force will be left to consolidate the position gained and the remainder will advance south-west against the enemy's trenches near Baby 700, which will be attacked simultaneously by a special detachment from within the Anzac position.
An advance by your force from the east will, as already indicated in paragraph 6, be of great assistance in the event of this attack being checked.
8. The landing of sufficient transport to secure the mobility of your force will be a matter of considerable difficulty. No animals or vehicles of any kind will be able to land in the first instance, and machine-guns, tools and necessary medical and signalling equipment must be carried by hand. All men will land with two iron rations (one day's meat ration only is advised); infantry will carry 200 rounds S.A.A. and machine-gun sections 3,500 rounds in belt boxes. Packs and greatcoats will not be taken ashore. Before dawn it is hoped to land enough horses to secure the mobility of the mountain artillery brigade and one battery R.F.A., and it is hoped that within the first 24 hours the disembarkation of all the personnel, horses and vehicles enumerated in the attached table will be complete.
One brigade R.F.A. 11th Division, 1/4th Lowland 5th Howitzer Brigade (two batteries) and the 10th Heavy Battery, will be landed at Anzac before the operations commence, and their personnel and horses will disembark on the morning following your disembarkation, and will then be directed along the beach to join your command.
Water is plentiful throughout the Anafarta Valley, but pending the disembarkation of water carts a number of mules with special 8-gallon water bags will be attached to the units of your command.
