The bombardment was continued vigorously for three-quarters of an hour. That the allied range finders had been doing accurate work was evidenced by the appearance of the German trenches when the British and French fire was turned against the supporting German trenches; but the Teutons' wire entanglements remained intact. Heretofore the big guns had been able to sweep such obstructions away. When the infantry reached the barbed wire, it found the Germans had improved this particular method of defense by using specially manufactured wire cable, well barbed, which was from one and one-half to two inches in diameter. And, to protect their cable entanglements, the Germans had built parapets in front of the entanglements. Their enemy's charging infantry coming upon such an obstruction could not cut it, and the only means of circumventing this new device was for the attacking force to throw their overcoats on the entanglements and crawl across the wire in the face of rifle and machine-gun fire. For a considerable distance along this part of the front the distance between the German and British trenches was not more than two hundred yards. At not a few sections the opposing trenches were near enough to permit the soldiers to converse with their opponents. The trenches for the most part were built on the marshland with sandbags, those of the British being khaki-colored, and the German being black and white. When the inevitable order to charge was given, the British artillery shifted its range to the German rear and the Eighth Division dashed over the black and white sandbags behind which the Germans were crouching. Beyond them was a ridge, in horseshoe formation, which was the last barrier that lay between the Allies and the plains that led to Lille. This ridge trails off in a northeasterly direction at Rouges Banes. Near the hamlet there was a small wood which had been taken by the Pathans and Gurkhas before the cannonade started. Among the regiments that led the attack of the Eighth Division were the Kensington Battalion of the London Regiment, the First Gloucesters, the Second Sussex, and the Northamptons. They were supported by the Liverpool Territorials, the First North Lancashires, the Second King's Royal Rifles, and the Sussex Territorials. The Germans had large bodies of reenforcements held at Lille, but they were unavailing; and the British took the first line of trenches though it required fifteen and a half hours to do it. Then they went on until they were on the slope of the ridge. Beyond that, however, it seemed impossible to proceed, for the Germans had such an array of machine guns trained on the approach to their second line of trenches that no human being could live in the face of their deadly fire. The British needed an equipment with which to bombard their enemy with high-explosive shells. Such an equipment they did not possess.
