This important attack was made upon May 9, over a front of about ten miles from the Laventie district in the north to that of Richebourg in the south. In the case of the northern attack it was carried out by Rawlinson's Fourth Corps, and was directed upon the sector of the German lines to the north-west of Fromelles at the point which is named Rouges Bancs. The southern attack was allotted to the Indian Corps (Willcocks) and the First Corps acting together. These two efforts represented the real foci of activity, but a general action was carried on from one end of the line to the other in order to confuse the issue, and hold the enemy in his trenches. Both in the north and in the south the special attack was opened by a sudden and severe bombardment, which lasted for about forty minutes. This had been the prelude to the victory of Neuve Chapelle, but in the case of Neuve Chapelle the British attack had been a complete surprise, whereas in this action of May 9 there is ample evidence that the Germans were well informed as to the impending movement, and were prepared for it. Their trenches were very deep, and more vulnerable to high explosives, in which we were deficient, than to shrapnel. None the less, the bombardment was severe and accurate, though, as it proved, insufficient to break down the exceedingly effective system of defence, based upon barbed wire, machine guns, and the mutual support of trenches. ------------------------------------------------------------------- {117} [Illustration: Southern Portion of Richebourg-Festubert Operations.] -------------------------------------------------------------------
