Strategically located along the roads leading to the Channel ports in Belgian Flanders, the Belgian city of Ypres had been the scene of numerous battles since the sixteenth century. With the German failure at the Battle of the Marne in September 1914 and the subsequent Allied counter attacks, the 'Race to the Sea' began.
This so called race ended at the North Sea coast after each army attempted to outflank the other by moving north and west. This area of Flanders, described by one historian as having the dreariest landscape in Western Europe, contained the last gap through which either side could launch a decisive thrust.
By October 1914, the Allies had reached Nieuport on the North Sea coast. The Germans, as a prelude to General Erich von Falkenhayn's Flanders Offensive, captured Antwerp and forced its Belgian defenders back to Nieuport, near Ypres.
Under the command of Field Marshall Sir John French, the British Expeditionary Force (BEF) retreated to Ypres after Antwerp fell. They arrived there between 8 and 19 October to bolster the Belgian and French defence. The Allied position around Ypres took the shape of a small salient in the trench lines because it could best be defended from the low ridge of higher ground to the east, but it was vulnerable to superior German artillery. The BEF held a thirty-five mile long line in the centre of the bulge while the French Army in the area, commanded by General Ferdinand Foch, manned the flanks to the south of the city.
At the outset of the battle, French and Foch both retained the hope of launching an offensive of their own. They believed a coordinated attack would enable the Allies to recapture the industrial city of Lille, Belgium, followed swiftly by Brussels. The new German Army Chief of Staff, Falkenhayn, quickly corrected their optimistic beliefs.
Falkenhayn's Flanders Offensive began on 20 October when he ordered an advance to break through the Allied line and capture the ports of Dunkirk, Calais, and Boulogne. He struck the Belgian defences on the Yser River between Dixmude and Nieuport.
The already weakened Belgian Army fought valiantly, but the German actions forced Belgium's King Albert to open the sluices that held back the sea. On 27 October, the Belgians flooded the land between their positions and the Germans' along the twenty-mile strip of land between Dixmude and Nieuport, creating a two-mile wide water barrier that forced Falkenhayn to halt and reconsider his plans.
The second phase of the Flanders Offensive was a series of assaults against the city of Ypres. To seize it, Falkenhayn had at his disposal the newly assembled Fourth Army (made up of units from the siege of Antwerp and eight new divisions manned by underage recruits) commanded by the Duke of Wurttemberg, a cavalry corps, and Prince Rupprecht of Bavaria's Sixth Army.
These forces gave the Germans a considerable numerical advantage over the BEF's seven infantry divisions (one was held in reserve) and three cavalry divisions. For replacements, General French could only count on a few divisions of Indian troops already en route as reinforcements. The Indian units would soon prove to be outstanding fighters in both offence and defence.
