Detached from the 1st Guards Brigade on August 31 the 2nd Battalion Grenadiers had been sent up to Carnoy to dig in rear of the Twentieth Division. It returned on September 3rd to Méaulte, where it underwent a thorough course of training, something in the nature of a dress rehearsal. Expert bombing officers gave instruction to every company in the Brigade, so that each man had an opportunity of learning the latest developments in bombing. All the battalions practised deploying in artillery formation, attacking an imaginary line of trenches, and then moving on immediately to a second objective. A great deal was learned in the way of signalling, and trials were made of a system of organising a single main trunk line, as central as possible, so as to avoid having a number of defective lines to each unit. This line was to consist of telephone or visual or relay posts――or, if possible, of all three. Careful consideration was given to the difficult task of getting the men across No Man’s Land, and every detail was rehearsed. Later the whole Brigade was practised in the attack, and in maintaining constant communication during an advance. [Sidenote: Sept. 9.] After a week the 1st Brigade received orders to proceed to Carnoy, and all surplus kit and equipment were left behind in store. The 2nd Battalion Grenadiers marched to Carnoy, and bivouacked not far from the place where it had been at the beginning of the month. [Sidenote: Sept. 11.] On the 11th orders were received for the 1st Brigade to relieve the left half of the 3rd Guards Brigade, while the 2nd Guards Brigade was to take the place of the other half. These orders (given below) were communicated to commanding officers at a conference held at Brigade Headquarters. Brigadier-General Pereira issued the following orders: 1ST GUARDS BRIGADE ORDER, NO. 73 1. The Fourth Army will attack the enemy’s defences between Combles Ravine and Martinpuich on Z day with the object of seizing Morval, Lesbœufs, Gueudecourt, and Flers, breaking through the enemy’s system of defence. The French are undertaking an offensive simultaneously on the south and the Reserve Army on the north. 2. The attack will be pushed with the utmost vigour, all along the line, until the most distant objectives are reached. The failure of a unit on a flank is not to prevent other units pushing on to their final objectives, as it is by such means that these units, which have failed, will be assisted to advance. 3. _Preliminary Bombardment._――(_a_) Commencing on the 12th September bombardment and wire-cutting on hostile defensive system will take place from 6 A.M. to 6.30 P.M. daily. (_b_) The preliminary bombardment on the day of the attack will be similar to that on previous days, there being no increase of fire previous to zero.
