The Battle of Messines was fought in October 1914 between the armies of the German and British empires, as part of the Race to the Sea, between the river Douve and the Comines–Ypres canal.

From 17 September – 17 October the belligerents had made reciprocal attempts to turn the northern flank of their opponent. Joffre ordered the French Second Army to move to the north of the French 6th Army, by moving from eastern France from 2–9 September and Falkenhayn ordered the German 6th Army to move from the German-French border to the northern flank on 17 September. By the next day French attacks north of the Aisne, led to Falkenhayn ordering the 6th Army to repulse French forces to secure the flank. When French advanced it met a German attack rather than an open flank on 24 September and by 29 September the Second Army had been reinforced to eight corps but was still opposed by German forces near Lille, rather than advancing around the German northern flank. The German 6th Army had also found that on arrival in the north, it was forced to oppose the French attack rather than advance around the flank and that the secondary objective of protecting the northern flank of the German armies in France had become the main task.

By 6 October the French needed British reinforcements to withstand German attacks around Lille. The British Expeditionary Force (BEF) had begun to move from the Aisne to Flanders on 5 October and reinforcements from England assembled on the left flank of the Tenth Army, which had been formed from the left flank units of the Second Army on 4 October. The Allies and the Germans, attempted to take more ground after the "open" northern flank had disappeared, the Franco-British attacks towards Lille in October, being followed up by attempts to advance between the BEF and the Belgian army by a new French Eighth Army. The moves of the 7th and then the 6th Army from Alsace and Lorraine had been intended to secure German lines of communication through Belgium, where the Belgian army had sortied several times during the period between the Franco-British retreat and the Battle of the Marne. In August British marines had landed at Dunkirk and in October a new 4th Army was assembled from the III Reserve Corps and the siege artillery used against Antwerp and four of the new reserve corps training in Germany.
