A short account has been given of what occurred to the division up to October 20. It will now be carried on for a few days, after which the narrative must turn to the First Corps, and show why and how they came into action to the north of the hard-pressed division. It is impossible to tell the two stories simultaneously, and so it may now be merely mentioned that from October 21 Haig's Corps was on the left, and that those operations which will shortly be described covered the left wing of the division, and took over a portion of that huge German attack which would undoubtedly have overwhelmed the smaller unit had it not been for this addition of strength. It is necessary to get a true view of the operations, for it is safe to say that they are destined for immortality, and will be recounted so long as British history is handed down from one generation to another. On the 21st the enemy got a true conception of {240} the salient in front of the Seventh Division, and opened a vigorous attack, which lasted all day and assumed several different phases at different points. The feature of the morning of the 21st was the severe and, indeed, disastrous artillery fire upon Lawford's 22nd Brigade. The exact range of the British position seems to have been discovered with deadly results. Men, trenches, and machine-guns were all blown to pieces together. The 2nd Warwicks and the 1st Welsh Fusiliers were the two battalions upon which the storm beat hardest, and each of them had some hundreds of casualties. In three days the Welsh Fusiliers, who were on the exposed left flank, lost three-quarters of their effectives, including twenty-three of their officers, and yet preserved their military spirit. It became clearer as experience accumulated that the best trenches, if they are once fairly located, can be made untenable or turned into the graves of their occupants by the use of high explosives. The German fire was so severe that it was reckoned that one hundred and twenty shells an hour into or round a trench was a not uncommon rate of fall. The 2nd Queen's also lost seven officers and many men in this day's fighting. In spite of the heavy losses from gun-fire the German infantry could make no progress, being held up by a flanking fire of the South Staffords. [Sidenote: Desperate attacks on Seventh Division.]
