The advance was extremely rapid--on the left two kilometres in less than one hour, in the centre three kilometres in forty-five minutes. At 10 a.m. we had reached the farm of Navarin. Towards the east the forward march was more difficult. Some German machine guns stood their ground in the wood of Sabot and contributed to the resistance of the enemy. This defence was destined to be overcome by surrounding them. Arriving at the wooded region in that part where it is intersected by the road from Souain to Tahure, the assailants joined up on September 27, 1915 with those of our troops who were attacking to the north of Perthes. They left behind them only what was barely necessary in the way of troops to clear the woods of stragglers. [Sidenote: The French take guns and supplies.] Parlementaires were sent to the Germans, who received them with a volley of rifle shots and endeavored to escape during the night. The majority were killed and the survivors surrendered. Several batteries and a large quantity of _materiel_ (supplies of shells and provisions, grenades, telephones, wire, light railways) remained in our hands. On the 28th, along the entire length of the sector, we were immediately in front of the second German position. The troops had shown an unparalleled ardour and energy. They had been trained by officers whose courage and spirit of self-sacrifice are indicated by this casualty list; a general of division and four colonels wounded; two colonels killed. [Sidenote: Wooded region between Souain and Perthes.] [Sidenote: Region broken up by mines and trenches.] (3) _Sector of Perthes._ Between Souain and Perthes stretches a wooded region in which already, in February and March, heavy fighting had taken place. At that period we had contrived to take possession on the eastern extremity of this region of the German defences of the wood of Sabot. We had also made progress to the north-west of Perthes, on the summit of Hill 200. But between these two positions the Germans had retained a strong system of trenches forming a salient almost triangular in shape, to which we gave the name of the Pocket (_la Poche_). During the whole year a war of mining had been going on, and the region, which was broken up by concave constructions and intersected in all directions by trenches and alleys of communication, constituted an attacking ground all the more difficult because to the north of la Poche the somewhat thickly wooded Trou Bricot, the edges of which were in a state of defence, obstructed a rapid advance. This wooded region extends over a width of a kilometre and a half and a depth of four kilometres. The arrangements made for the attack contemplated, after the capture of la Poche, the surrounding of the wood of the Trou Bricot. The junction was to be made at the road from Souain to Tahure, with the troops assigned for the attack on the eastern border of the hollow at Souain. [Sidenote: The York trench.]
