It will be remembered that the Fifty-second and Fifty-sixth Divisions had fought their way to the Hindenburg Line on August 23. This was too formidable an obstacle to be taken in their stride, and the most that could be hoped was that they should get into a good position for the eventual attack. The Fifty-second Division had shown the metal of the Palestine Army by a very fine advance which made them masters of Henin. On their right was the 167th Brigade, with the 1st London and the 7th and 8th Middlesex in the line. These troops pushed right into the outskirts of Croisilles, but it was clear that new German divisions were in the line, and that the resistance had very much hardened. The Londoners were unable to hold the village, and the Fifty-second Division was also held up on Henin Hill by very strong fire. Matters seemed to have come to a stand in that quarter. Early on the morning of the 25th the Guards 3rd {109} Brigade and the 186th and the 187th Brigades of the Sixty-second Division made a resolute advance to clear their front and get nearer to that terrible paling which was meant to enclose the German domain. It was a day of very hard fighting for all three brigades, and they had ample evidence that the German line had indeed been powerfully reinforced, and had no intention of allowing General Byng to establish himself in the very shadow of their fortifications if they could hold him off. The opening was inauspicious, for by some mistake there was an error of half an hour in starting-time between the two divisions. As a result the Guards found themselves on the line of road between Mory and St. Leger with an open flank and under heavy enfilade fire, which made many gaps in the ranks of the 1st Grenadiers. At the same time the leading tanks were put out of action on that flank. In the centre the tanks lost their way in the mist, but the 2nd Scots Guards pushed ahead in spite of it. Banks Trench, however, in front of them was very strongly held and the assault was not pressed. On the left the 1st Welsh were in St. Leger Wood, but Croisilles was still untaken and the advance could not be carried forward as the machine-guns from this village swept the country. About 9 A.M. the enemy buzzed out of the Hindenburg Line and fell upon the Scots Guards, but were shot back again into their cover. During these operations the Guards captured a battery of field-guns.
