Before giving in detail the circumstances which determined the result in each division, it may be well to avoid wearisome iteration by giving certain facts which are common to each. In every case the troops advanced in an extended formation of companies in successive waves. In nearly every case the German front line was seized and penetrated, in no case was there any hesitation or disorder among the advancing troops, but the highest possible degree of discipline and courage was shown by regulars, territorials, and men of the New Army, nor could it be said that there was any difference between them. In each case also {48} the Germans met the assault with determined valour; in each case the successive lines of trenches were more strongly held, and the assailants were attacked from the rear by those who emerged from the dug-outs behind them, and above all in each case a most murderous artillery fire was opened from a semi-circle all round the German position, but especially from one huge accumulation of heavy guns, said to number a hundred batteries, stationed on the high ground near Bucquoy and commanding the British position. These guns formed successive lines of barrage with shrapnel and high explosives, one of them about 200 yards behind the British line, to cut off the supports; another 50 yards behind; another 50 yards in front; and a fourth of shrapnel which was under observed control, and followed the troops in their movements. The advanced lines of assault were able in most cases to get through before these barrages were effectively established, but they made it difficult, deadly, and often impossible for the lines who followed.
