La Bassée
The 6th Army had arrived in northern France and Flanders from the south and progressively relieved German cavalry divisions, VII Corps taking over from La Bassée to Armentières on 14 October, XIX Corps next day around Armentières and XIII Corps from Warneton to Menin. Attacks by the British II and III Corps caused such casualties that XIII Corps was transferred south from 18 to 19 October in reinforcement. The 6th Army line from La Bassée to Armentières and Menin, was ordered not to attack until the operations of the new 4th Army in Belgium had begun. Both armies attacked on 20 October, the XIV, VII, XIII and XIX corps of the 6th Army making a general attack from Arras to Armentières. Next day the northern corps of the 6th Army attacked from La Bassée to St Yves and gained little ground but prevented British and French troops from being moved north to Ypres and the Yser fronts. On 27 October, Falkenhayn ordered the 6th Army to move heavy artillery north for the maximum effort due on 29 October at Gheluvelt, to reduce its attacks on the southern flank against II and III corps and to cease offensive operations against the French further south. was formed from XIII Corps and reinforcements from the armies around Verdun, which further depleted the 6th Army and ended the offensive from La Bassée north to the Lys.
