The plan of operations provided for an initial destructive barrage to wreck the enemy’s first line defences opposite the II Serbian Army; then their artillery positions were to be bombarded and reinforcements prevented from coming up; finally, when a breach for the II Army was made, the artillery was to alter its direction and open up another gap for the I Army. The duty of the infantry was to try to capture all the positions between the Sokol and the Vetrenik, so as to penetrate as deeply as possible into the enemy’s lines in the direction of the apex of the triangle formed by the Cerna and the Vardar. If this plan succeeded, the enemy’s communications to the right and the left would be threatened. In a second phase the British XII Corps was to attack the two Couronnés and the P ridges to the west of Lake Doiran, while the XVI Corps was to attempt to turn the positions to the north-east of the lake, so as to threaten the road leading into Bulgaria by the Kosturino Pass and Strumitza. Above all it was to be the task of the British to prevent the enemy opposing them from sending reinforcements to the Serbian front, just as our forces were to fulfil a similar function on the Hill 1050 sector. Indeed, the best troops of the whole of the enemy Army were those opposite the British and the Italian sectors. In the third phase the Italians were to attack the famous 1050, with Prilep as their objective, while the Franco-Greek Group to our right was to advance along the Cerna. In the fourth phase the rest of the A.F.O. would enter the lists, attacking the positions around Monastir, also with Prilep as their objective. The final phase was to be an offensive by the I Greek Corps beyond the Struma, with a view to capturing Serres, Demir Hissar and the Rupel road leading into Bulgaria towards Djumaya. In view of the weakness of the effectives, it would be necessary to transfer the scanty available reserves and the artillery from one sector to another, and the various phases of the action were so arranged as to give those forces time to effect the movements contemplated--by no means an easy task on account of the state of communications in Macedonia.
