Still more importance, however, lay in the proof afforded by the results described of the ability of our new armies, not only to rush the enemy's strongest defenses, as had been accomplished on July 1 and 14, 1916, but also to wear down and break his power of resistance by a steady, relentless pressure, as they had done during the weeks of this fierce and protracted struggle. As has already been recounted, the preparations made for our assault on July 1, 1916, had been long and elaborate; but though the enemy knew that an attack was coming, it would seem that he considered the troops already on the spot, secure in their apparently impregnable defenses, would suffice to deal with it. The success of that assault, combined with the vigor and determination with which our troops pressed their advantage, and followed by the successful night attack of July 14, 1916, all served to awaken him to a fuller realization of his danger. The great depth of his system of fortification, to which reference has been made, gave him time to reorganize his defeated troops, and to hurry up numerous fresh divisions and more guns. Yet in spite of this, he was still pushed back, steadily and continuously. Trench after trench and strong point after strong point were wrested from him. The great majority of his frequent counterattacks failed completely, with heavy loss; while the few that achieved temporary local success purchased it dearly, and were soon thrown back from the ground they had for the moment regained. The enemy had, it is true, delayed our advance considerably, but the effort had cost him dear; and the comparative collapse of his resistance during the last few days of the struggle justified the belief that in the long run decisive victory would lie with our troops, who had displayed such fine fighting qualities and such indomitable endurance and resolution. [Sidenote: Mouquet Farm in hands of British.] Practically the whole of the forward crest of the main ridge on a front of some 9,000 yards, from Delville Wood to the road above Mouquet Farm, was now in our hands, and with it the advantage of observation over the slopes beyond. East of Delville Wood, for a further 3,000 yards to Leuze Wood, we were firmly established on the main ridge, while further east, across the Combles Valley, the French were advancing victoriously on our right. But though the centre of our line was well placed, on our flanks there was still difficult ground to be won. [Sidenote: High ground from Ginchy to Morval.]
