The results of the operations of July 4, 1916, and subsequent days were of considerable importance. The enemy's second main system of defense had been captured on a front of over three miles. We had again forced him back more than a mile, and had gained possession of the southern crest of the main ridge on a front of 6,000 yards. Four more of his fortified villages and three woods had been wrested from him by determined fighting, and our advanced troops had penetrated as far as his third line of defense. In spite of a resolute resistance and many counterattacks, in which the enemy had suffered severely, our line was definitely established from Maltz Horn Farm, where we met the French left, northward along the eastern edge of Trones Wood to Longueval, then westward past Bazentin-le-Grand to the northern corner of Bazentin-le-Petit and Bazentin-le-Petit Wood, and then westward again past the southern face of Pozieres to the north of Ovillers. Posts were established at Arrow Head Copse and Waterlot Farm, while we had troops thrown forward in Delville Wood and toward High Wood, though their position was not yet secure. [Sidenote: Sir Henry Rawlinson commended.] I cannot speak too highly of the skill, daring endurance, and determination by which these results had been achieved. Great credit is due to Sir Henry Rawlinson for the thoroughness and care with which this difficult undertaking was planned; while the advance and deployment made by night without confusion, and the complete success of the subsequent attack, constitute a striking tribute to the discipline and spirit of the troops engaged, as well as to the powers of leadership and organization of their commanders and staffs. [Sidenote: Guns and prisoners taken.] During these operations and their development on the 15th a number of enemy guns were taken, making a total capture since July 1, 1916, of eight heavy howitzers, four heavy guns, forty-two field and light guns and field howitzers, thirty trench mortars, and fifty-two machine guns. Very considerable losses had been inflicted on the enemy, and the prisoners captured amounted to over 2,000, bringing the total since July 1, 1916, to over 10,000. [Sidenote: Enemy able to bring up fresh troops.] There was strong evidence that the enemy forces engaged on the battle front had been severely shaken by the repeated successes gained by ourselves and our allies; but the great strength and depth of his defenses had secured for him sufficient time to bring up fresh troops, and he had still many powerful fortifications, both trenches, villages, and woods, to which he could cling in our front and on our flanks. We had, indeed, secured a footing on the main ridge, but only on a front of 6,000 yards, and desirous though I was to follow up quickly the successes we had won, it was necessary first to widen this front. [Sidenote: Pozieres and Thiepval still to be carried.]
