After HKK 4 moved south of the Lys again on the night of 14/15 October, the 3rd Cavalry Division concentrated around Armentières, with the 6th Cavalry Division to the west and the Bavarian Cavalry Division around Sailly-sur-la-Lys and then withdrew to an area between Armentières and Laventie a day later, before being replaced by infantry units of the 6th Army as they arrived and retiring to Lille. As XIX Corps occupied Lille on 12 October, each side began a final effort to round the northern flank of its opponent. With Lille secure, the 6th Army moved the XIII Corps west around Lille, units of the 26th Division moving north of the town to occupy Menin on 14 October and began a march towards Ypres. Patrols reached Gheluvelt and Becelaere as British forces began to advance eastwards from Ypres, which according to the plans laid by Falkenhayn, were not to be opposed but allowed to advance into a trap to be sprung by the 4th Army as it advanced from Ghent into the flank and rear of the Allied armies. As the 6th Army was to operate defensively during this period, more infantry was needed in the south of the army area. Falkenhayn ordered the right flank units to form a defensive flank in the north, from La Bassée to Armentières and Menin, coinciding with a growing artillery ammunition shortage, which reduced the offensive capacity of the 6th Army in any case. XIX Corps was ordered to send the 40th Division round the north of Armentières and the 24th Division to the south, which led to several engagements with the British 4th Division near Le Gheer and Ploegsteert. By 15 October, the infantry regiments of the 40th Division had reached the Lys and deployed southwards from Warneton to La Basseville and Frélinghien. The infantry dug in on rises to gain a better view of the surroundings. Soon afterwards, outposts were established at Pont Rouge and Le Touquet, to coincide with a general attack by the 4th Army further north. The 4th and 6th divisions advanced on 13 October and found German troops dug in along the Meterenbecque. A corps attack from La Couronne to Fontaine Houck began at 2:00 p.m. in wet and misty weather, which by evening had captured Outtersteene and Méteren, at a cost of 708 casualties. On the right, the French II Cavalry Corps (de Mitry) attempted to support the attack but with no howitzers could not advance in level terrain, which was dotted with cottages improvised as strong points by the Germans; on the northern flank the British cavalry took Mont Noir near Bailleul.
