On October 11 it was found that the Germans were in strength and apparently meant to make a serious stand. At about ten o'clock they counter-attacked with tanks, and pushed back both the Canadians on the left and the Twenty-fourth Division on the right. The former had taken Iwuy in the morning. No further advance was made during the day, but general orders were issued that the way should be cleared up to the Selle River, and that the high ground over the river should be secured in order {228} to safeguard the crossings. On October 12 the Canadian Corps on the left was drawn out of the line, and the Seventeenth Corps found themselves with the Forty-eighth Division of the Twenty-second Corps as their northern neighbours. On this day the Germans again began to retreat, and the Corps front was advanced down to the Selle River, between Haussy and Saulzoir. There was hardly any opposition. All day the Twenty-fourth Division was advancing with the Forty-ninth on their left and the Guards on their right. That evening the 17th Brigade of the Twenty-fourth Division made progress over the river, entering Montrecourt and securing the undamaged bridge. The posts on the farther side were swept by machine-gun fire and driven back next morning, that portion of the bank being commanded by rising ground on the east. We have thus traced all four Corps of the Third Army from the date August 21, when it started from the line of Albert, until October 13, when it found itself after seven weeks of immense and continuous exertion and of uninterrupted victory upon the western bank of the Selle. In the compressed narrative of this chronicle it might seem no more complex than the forward movement of pieces upon a board, but no detailed account could ever make real the problems, the anxiety, the organisation, the unwearied heroic efforts which such an advance must entail when the great German army, now composed of veterans deeply skilled in every wile of modern warfare, were beaten out of position after position, and could find no safe refuge anywhere from the nation whose military weakness had for so long been its standing jest. {229} CHAPTER IX OPERATIONS OF BYNG'S THIRD ARMY From the Battle of the Selle, October 12, to the end The battle of the Selle River--Reversion to open warfare--The valour of Lancashire--Haig's incessant blows--Weakening of the German morale--The battle of Mormal Forest--New Zealanders and the mediaeval fortress--Capture of the great forest--The Sambre bridged---A grand Division--Advance of Fergusson's Seventeenth Corps--The last phase.
