The front of the new attack upon September 20 was about eight miles in length, and corresponded closely with the front attacked upon July 31, save that it was contracted in the north so that Langemarck was its limit upon this side. Upon the south the flank was still fixed by the Ypres-Comines Canal, just north of Hollebeke. The scheme of the limited objective was closely adhered to, so that no advance of more than a mile was contemplated at any point, while a thousand yards represented the average depth of penetration which was intended. The weather, which had given a treacherous promise of amendment, broke again upon the very night of the assembly, and the troops were drenched as they lay waiting for the signal to advance. Towards morning the rain stopped, but drifting clouds and a dank mist from the saturated soil deprived the attackers of the help of their aircraft--so serious a handicap to the guns. But the spirits of the men rose with the difficulties, after the good {181} old British fashion, and at 5.40 on this most inclement morning, wet and stiff and cold, they went forward with cheerful alacrity into the battle. The field of operations was now covered by two British armies, that of Gough in the north extending from beyond Langemarck to the Zonnebeke front, while Plumer's Army covered the rest of the line down to Hollebeke. It may be said generally that the task of the men in the south was the more difficult, since they had farther to advance over country which had seemed to be almost impregnable. None the less the advance in the north was admirably executed and reached its full objectives. Cavan's Fourteenth Corps still held the extreme north of the British line, but neither they nor the French upon their left were really engaged in the advance. They covered the front as far south as Schreiboom, where the right of the Twentieth Division joined on to the left of the Fifty-first Highlanders. This latter division formed the left flank of the main advance, though the 59th Brigade, the 60th Brigade, and the 2nd Brigade of Guards did push their line some short distance to the front, on either side of the Ypres-Staden Railway, the 59th Brigade capturing Eagle Trench and the 60th Eagle House. This was a very formidable position, crammed with machine-guns, and it took four days for its conquest, which was a brilliant feat of arms carried out by men who would be discouraged by no obstacle. The garrison were picked troops, who fought desperately, and everything was against the attack, but their pertinacity wore down the defence and eventually, upon Sept. 23, the 10th Rifle Brigade and the 12th Royal Rifles cleared up the last corner of the widespread stronghold. {182}
