But the detraining took longer than had been expected, and it was not possible to attack the Germans during the time when they had only cavalry in the Lille district and further to the north.
There remained the Belgian Army. On leaving Antwerp on October 9 the Belgian Army, which was covered by 8,000 British bluejackets and 6,000 French bluejackets, at first intended to retire as far as to the north of Calais, but afterwards determined to make a stand in Belgian territory. Unfortunately, the condition of the Belgian troops, exhausted by a struggle of more than three months, did not allow any immediate hopes to be based upon them. This situation weighed on our plans and delayed their execution.
On the 16th we made progress to the east of Ypres. On the 18th our cavalry even reached Roulers and Cortemark. But it was now evident that, in view of the continual reinforcing of the German right, our left was not capable of maintaining the advantages obtained during the previous few days. To attain our end and make our front inviolable a fresh effort was necessary. That effort was immediately made by the dispatch to the north of the Lys of considerable French forces, which formed the French Army of Belgium.
The French Army of Belgium consisted, to begin with, of two territorial divisions, four divisions of cavalry, and a naval brigade. Directly after its constitution it was strengthened by elements from other points on the front whose arrival extended from October 27 to November 11. These reinforcements were equivalent altogether in value to five army corps, a division of cavalry, a territorial division, and sixteen regiments of cavalry, plus sixty pieces of heavy artillery.
Thus was completed the strategic manoeuvre defined by the instructions of the General in Chief on September 11 and developed during the five following weeks with the ampleness we have just seen. The movements of troops carried out during this period were methodically combined with the pursuit of operations, both defensive and offensive, from the Oise to the North Sea.
On October 22 our left, bounded six weeks earlier by the Noyon district, rested on Nieuport, thanks to the successive deployment of five fresh armies--three French armies, the British Army, and the Belgian Army.
