On the 27th we penetrated into this position at two points. We took possession of a trench about a kilometre wide, called the "parallel of the Epine de Vedegrange," which is duplicated almost throughout by another trench (the parallel of the wood of Chevron), and the wirework entanglements of which were intact, and precluded an assault. Further east our soldiers also continued, thanks to the conformation of the terrain, to penetrate into the enemy trench to a depth of about four hundred metres. But it was impossible to take advantage of this breach owing to a concentration of the German heavy artillery, a rapidly continued defence of the surrounding woods, and the fire of machine guns which it was not possible to capture and which were directed from the trenches on the right and left of the entry and exit to the breach. The results attained in this attacking sector alone may be stated thus: fifteen square miles of territory organized for defence throughout nearly the whole of its extent; on September 28, forty-four cannon, seven of 105 and six of 150, and more than three thousand prisoners. (2) _Sector of Souain._ The enemy lines round about Souain described a wide curve. In the immediate vicinity of our trenches, to the west at the Mill and to the east of the wood of Sabot, they swerved to the extent of over a kilometre to the north of the village and of the source of the Ain. [Sidenote: Sapping operations.] [Sidenote: Assault made in three directions.] When the offensive was decided upon it was necessary, in order to extend our lines forward to striking distance, to undertake sapping operations in parallel lines, and at times to make dashes by night over the intervening ground. The men working underground got into communication with the trenches by digging alleys of communication. This difficult undertaking was effected with very slight losses, under the eyes and under the fire of the enemy. Our parallel lines approached to within a distance of two hundred metres of the German trenches. The assault was made in three different directions: on the west in the direction of Hills 167 and 174; in the centre along a line running parallel with the road from Souain to Pomme-Py, in the direction of the farm of Navarin; on the east in the direction of the woods intersected by the road from Souain to Tahure, and in the direction of the Butte de Souain. [Sidenote: Machine gun positions surrounded.]
