Owing to its peculiar position every advantage was in favor of the defense. Maltzhorn Ridge commanded the southern part, and the German position at Longueval commanded the northern portion. The German second line in a semicircle extended around the wood north and east, and as the covert was heavy, organized movement was impossible while the German artillery had free play. The British, however, continued to advance slowly and stubbornly from the southern point where they had obtained a foothold, but it was not until the fire of the German guns had been diverted by pressure elsewhere that they were able to make any appreciable gains on their way northward. On July 9, 1916, at 8 o'clock the Germans launched desperate counterattacks directed from the east to the southeast. The first failed; the second succeeded in landing them in the southern part of the wood, but they were ultimately repulsed with heavy losses. During the night there was a fresh German attack strongly delivered that was broken by British fire. Of the six counterattacks delivered by the Germans between Sunday night and Monday afternoon, July 9-10, 1916, the last enabled them to gain some ground in the wood, but it was at a heavy cost. They did not long enjoy even this small success, for on Tuesday, July 11, 1916, the British had recaptured the entire wood excepting a small portion in the extreme northern corner. On the same date the British advanced to the north end of Mametz Wood, and by evening of July 12, 1916, had captured virtually the whole of it, gathering in some hundreds of German prisoners in the operation. The place had not been easily won, for while the whole wood did not comprise more than two hundred acres or so, there was a perfect network of trenches and apparently miles of barbed-wire entanglements, while machine guns were everywhere. It was only after the British succeeded in clearing out machine-gun positions on the north side, and enfiladed every advance, that they were able to get through the wood and to face at last the main German second position. This ran, as will have been noted, from Pozieres through the Bazentins and Longueval to Guillemont. The capture of Contalmaison was a necessary preliminary to the next stage of the British advance. After the fall of this place Sir Douglas Haig issued a summary of the first of the gains made by the Allies since the beginning of the offensive:
