Reference Map Anafarta Sagir Gallipoli Map 1/20,000.

1. The General Commanding has decided to ma.s.s the whole of his reinforcements in and immediately north of the area occupied by the corps under your command, with a view to securing Suvla Bay as a base of operations, driving the enemy off the Sari Bair, and eventually securing a position astride the Gallipoli Peninsula from the neighbourhood of Gaba Tepe to the straits north of Maidos.

2. The general outline for your proposals for the action of the A. and N.Z. Army Corps contained in your G a 89 of 1st July are approved.

3. (_a_) The General Commanding wishes your operations to begin on August 6th with a strong and sustained attack on Hill 125 (Plateau 400), every effort being made to deceive the enemy as to the locality against which our main effort is to be made, and to induce him to believe that it will be directed against his lines opposite the southern portion of your position. In pursuance of this object the Vice-Admiral has arranged that H.M. ships shall in the meantime display increased activity off the coast between Gaba Tepe and k.u.m Tepe. It has been arranged that soundings shall be taken by night off the coast south of Gaba Tepe; and, on the evening of August 6th, a naval demonstration will be made off this part of the coast, H.M. ships being accompanied by a number of trawlers as if a landing were to be undertaken.

(_b_) The General Commanding further concurs in the subsequent sequence of the operations outlined by you, namely:--

(i) The clearing of the enemy's outposts from the ridges facing Nos. 2 and 3 posts, to be undertaken after nightfall.

(ii) An attack in as great strength as possible up the Sazli Beit Dere, the Chailak Dere and the Aghyl Dere, against the Chunuk Bair ridge, by night.

(iii) When the Chunuk Bair ridge is gained, a converging attack from that ridge, and from the north-eastern section of your present position, against Hill 180 (Baby 700).

4. (_a_) For the above operations the following troops will be at your disposal:--

A. and N.Z. Army Corps. 13th Division, less all artillery except 69th F.A. (Howitzer) Brigade. 29th Brigade (10th Division). 29th Indian Brigade.

(_b_) At the date of commencement of the operations the following troops belonging to or attached to the 9th Army Corps will be at Anzac, but will not, except so far as is stated hereunder, be at your disposal:--

One F.A. Brigade, 11th Division: To rejoin 9th Army Corps as soon as horses are landed.

10th Heavy Battery, R.G.A.: Ditto.

14th Lowland (Howitzer) Brigade (two Batteries): Arrangements must be made so that these batteries may be free to rejoin the 9th Army Corps before nightfall on August 7th.

5. The operations carried out by the Corps under your command will form part of a general combined offensive undertaken by the whole of the forces of the Gallipoli Peninsula and by the 9th Army Corps, which will be disembarked in the neighbourhood of Suvla Bay, beginning on the night of August 6th-7th.

(_a_) The 8th Army Corps, in conjunction with the Corps Expeditionnaire, will attack the Turkish lines south of Krithia on August 4th and 5th.

The attack will be made on a large scale, and will be vigorously pressed, and it is hoped that by its means the enemy will be induced to move part of his central reserves southward into the Cape h.e.l.les zone during the 5th and 6th, so that they may not be available in the northern zone on the 6th and 7th.

(_b_) The 9th Army Corps will begin landing in and close to Suvla Bay during the night of August 6th-7th. Three infantry brigades, with one field and two mountain batteries, engineers and medical services, should be ash.o.r.e before dawn, and will be closely followed by two more infantry brigades and additional artillery and engineers.

The G.O.C. 9th Army Corps has been informed:--

(i) That his mission is to secure Suvla Bay as a base of operation for all the forces in the northern zone.

(ii) That the seizure of Yilghin Burnu and Ismail Oglu Tepe ("W" and Chocolate Hills), on account of the presence there of artillery which may interfere with your operations, must be considered as of very special importance.

(iii) That so far as is possible after the fulfilment of his primary mission, he is to render you such direct a.s.sistance as may be practicable by moving any available troops via Biyuk Anafarta up the eastern slopes of the Sari Bair.

(_c_) At the commencement of these operations the infantry of the 53rd Division will be available as Army Reserve and will be at the disposal of the General Commanding.

6. The Vice-Admiral has agreed provisionally to the following allotment of ships affording naval support to the operations:--

In Suvla Bay: One 6-in. monitor.

South of Kuchuk: H.M.S. _Endymion_.

Kemliki (Nibrunesi Point): H.M.S. _Edgar_, H.M.S. _Talbot_, one 6-in.

monitor, one 9.2-in. monitor. These ships would be in position at daylight on August 7th, and would mainly be required to support the operations of the 9th Army Corps.

West of Gaba Tepe: H.M.S. _Baccanto_, H.M.S. _Humber_, H.M.S.

_Havelock_, one 6-in. monitor.

These ships would be in position at 3 p.m. on August 6th, except H.M.S.

_Havelock_, which would be in position at daylight on August 7th. They would be detailed for support of the right flank of the A. and N.Z. Army Corps.

Off k.u.m Tepe: One 6-in. monitor.

A separate communication is being sent to you with regard to the final settlement of details as to the support of the operations by naval guns, allocation of targets, etc.

7. Special instructions regarding signal communication will be issued later. In general terms the arrangements will be as follows:--

A submarine cable and a land cable will be laid between Anzac and Suvla Bay as soon as circ.u.mstances permit.

A submarine cable will also be laid as soon as practicable between Imbros and Suvla Bay. Pending the completion of connection between Anzac and Suvla Bay, inter-communication will be carried out by lamp.

Two military pack W/T stations and a R.N. Base W/T station will be established in the vicinity of Suvla Bay. The W/T station at Anzac will be able to intercept messages from seaplanes, but must not attempt to reply.

W/T via the ships will be an alternative means of communication between G.H.Q. and the troops ash.o.r.e in case of interruption of cable communication.

A system of flares will be arranged for employment on the left flank of your position at dawn on August 7th to indicate to the ships the positions reached by the troops.

8. G.H.Q. will in the first instance be at Imbros.
