(_e_) At zero + 3 hours 30 minutes, the creeping barrage will become intense on a line 200 yards in front of the third objective――and will advance at rate of 30 yards per minute until it has passed 200 yards beyond fourth objective, when it will become stationary. This barrage is to cover the advance of the tanks. There will be no creeping barrage in front of the infantry during the advance to the fourth objective, which commences at zero + 4 hours 30 minutes. (_f_) In the attack on first and second objectives gaps of 100 yards wide will be left in the creeping barrage for the routes of the tanks. 9. The attack will be carried out as follows: (_a_) The 2nd and 3rd Battalions Coldstream Guards will attack and capture the first, second, and third objectives. The dividing line between these battalions is shown on attached maps. (_b_) The 2nd Battalion Grenadier Guards will move in rear of the 2nd and 3rd Battalions Coldstream Guards. When the latter advance to the assault of the second objective the 2nd Battalion Grenadier Guards will occupy the first objective until the 1st Battalion Irish Guards have passed through them; they will then follow and support them in their attack on the fourth objective. The rôle of the 1st Battalion Grenadier Guards is to form a defensive flank, if necessary, and to support the attack of the 1st Battalion Irish Guards in their attack on the fourth objective, with such troops as are not required for a defensive flank. (_c_) 1st Battalion Irish Guards will attack the fourth objective. (_d_) Machine-gun Coy. One section will accompany each battalion in the assault, and will be under the orders of the O.C. Battalion. (_e_) Stokes T.M. Battery. Four guns will accompany the 2nd Battalion Grenadier Guards in case it is necessary to form a defensive flank. They will not go farther than the second objective. They will act under the orders of the O.C. Battalion. The remaining four guns will be in the trench in which advanced Brigade Headquarters is situated, S.24.b.6.2. (_f_) The 75th Field Coy. and the four work platoons will remain in their forming-up area until further orders are received. 10. _Formation of Attack._――The formation for the carrying out of the attack is shown on attached sketch. The 2nd Battalion Grenadier Guards and 1st Battalion Irish Guards will move into line or small columns according as to whether they are under rifle-fire or not. 11. The flow of troops will be continuous. This is to ensure a strong attack being pressed against each successive objective.
