(iii) To advance the French field batteries eastwards in order to bring fire to bear on the ridge which dominates the right bank of the river Avre.
The three French Divisions attacking were the 152nd Division on the right, the 3rd in the centre, and the 15th on the left. Their respective frontages were 950, 2,000, and 800 metres. The greatest depth of the attack was 3,000 metres.
The operation was to be launched as a surprise, after a short and intense artillery preparation; the main objectives were to be captured by encircling them and then “mopping” them up.
There were three objectives: The first included Bois des Arrachis, Sauvillers, Mongival village, Adelpare farm and Ouvrage-des-Trois-Bouqueteaux; twelve tanks and four battalions of infantry were detailed for this. The second included the clearing of the plateau to the north of the Bois-de-Sauvillers and the capture of the south-west corner of the Bois-de-Harpon; the number of tanks allotted to this objective was twenty-four, with four fresh infantry battalions. The third, known as the Blue Line, an outpost line covering the second objective, was to be occupied by eight strong infantry patrols and all available machines.

The attack was to be preceded by one hour’s intensive bombardment, including heavy counter-battery fire. The creeping barrage was to consist of H.E. and smoke shells and was to move at the rate of 200 metres in six minutes up to the first objective, after this at the rate of 200 metres in eight minutes.
Tanks were to attack in sections of three, two in front and one in immediate support, the infantry advancing in small assaulting groups close behind the tanks.
Directly the orders were issued preparations were set on foot. On July 18, Lieutenant-Colonel H. K. Woods, commanding the 9th Battalion, and his reconnaissance officers visited General de Bourgon,[31] the Commander of the 3rd French Division, who explained to them the scheme; on the next day these officers reconnoitred the ground over which the battalion would have to operate, and tactical training was carried out with the French at the 5th Tank Brigade Driving School at Vaux-en-Amienois. On the 20th and 21st training continued, and further examination of the ground was made, and on the 22nd details of the attack were finally settled. In spite of the continuous exertion of the last few days all ranks were in the greatest heart to show the 3rd French Division what the British Tank Corps could do.
