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 circumstances 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 ashore 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.
