In the second stage of the Canadian attack the First Canadian and the Eleventh British {258} Divisions--the latter on the extreme left--took up the running, and carried the line forward in the direction of Raillencourt and Haynecourt. In the afternoon the 169th Brigade of the Fifty-sixth Division also came in upon the left, near the Arras-Cambrai Road, to clear the area between the Eleventh Division and the Canal du Nord, the latter division having taken Oisy-le-Verger. There was constant fighting during the day in this quarter, the 168th Brigade coming into action to the left of the 169th, and next morning the 8th Middlesex took Palluel. They also crossed the River Sensée and captured Arleux, but a strong barrage, followed by an infantry attack, drove them out again at 3.30 on the morning of September 29. All these attacks, both of the Eleventh and Fifty-sixth Divisions, were made, after crossing the Canal du Nord, from south to north, so as to extend the left flank of the Canadians. One of the predominating factors in these operations was the great flood caused by the blocking of the Trinquis and Sensée rivers by the Germans, which created wide lakes shown upon no map, across the front of the Twenty-second Corps. As a matter of fact this development was regarded with some complacency by General Godley, for there had always been a chance that the Germans, by driving a really strong counter-attack along the line of the Scarpe, might checkmate the whole British advance to the south. The effect of the inundations was to free the British higher command from any fears of the kind and to enable them to hold that part very lightly, while they thickened their line elsewhere.
