CORPS ORDERS FOR THE BATTLE OF AUGUST 8TH, 1918 The following were the complete orders issued by the Australian Army Corps for the Battle of August 8th, 1918. They form only a small part of the whole of the orders which were required for the operation. There were, in addition, detailed orders by the Corps Artillery Headquarters, the Heavy Artillery, the Chief Engineer, and each of the five Divisions and fifteen Brigades, and also by the Administrative Services of the Corps. On the question of the form of the orders, the most expedient course was found to be the one here adopted--namely, that of issuing a numbered series of Battle Instructions, each dealing comprehensively with a separate subject matter: BATTLE INSTRUCTIONS NO. 1 1. The Australian Corps will attack the enemy from the VILLERS-BRETONNEUX--CHAULNES Railway exclusive to the River SOMME, inclusive, at a date and hour to be notified. The Canadian Corps will co-operate on the right, south of the railway (inclusive), and the Third Corps on the left, north of the SOMME. 2. _General Method of Attack._--The Australian Corps will attack on a two-division front. The attack will be carried out in three phases. Divisional boundaries and objectives are shown on the attached map. (i) _First Phase._--The 2nd and 3rd Australian Divisions will form up on a taped line prior to ZERO, and will attack with Tanks under a creeping artillery barrage. Their objective is shown by a GREEN line on the attached map. On arrival at their objective they will consolidate. (ii) _Second Phase._--The 5th and 4th Australian Divisions, organized in brigade groups, will advance in open warfare formations, from the first objective passing through 2nd and 3rd Australian Divisions respectively. Their objective is shown in RED on the map. (iii) _Third Phase._--The 5th and 4th Australian Divisions will exploit their success and seize the old British line of Defences marked BLUE on the map, and establish themselves defensively on this line. (iv) The 1st Australian Division will be in Corps Reserve. (v) A detailed programme of the action will be issued. 3. _Assembly._--In order to free as many troops from line duty as possible, 2nd and 3rd Australian Divisions will arrange to hold the front with one infantry brigade on each Divisional sector. This will be completed before daybreak on 5th August. To prevent any troops arriving at their objectives in an exhausted condition through a long march, troops detailed to the farthest objectives must be quartered nearest the starting line prior to ZERO. The brigades of 2nd and 3rd Australian Divisions not holding the line will be quartered in rear of all brigades of 5th and 4th Australian Divisions respectively prior to ZERO night. This will be completed before daybreak on 5th August.
