Hazebrouck is a commune in the Nord department in northern France. Hazebrouck in Flanders was a small market town before it became an important railway junction in the 1860s. West Flemish was the usual popular language used in the town until 1880. At that time French was taught at school by mandate of the French government in an effort to "Frenchify" the people of the Nord-Pas-de-Calais and to extinguish their Flemish roots. The development of the railways linked Hazebrouck to Lille to Calais and Dunkirk.World War I: Fourth Battle of Ypres and HazebrouckAn attack by the German army was proposed in October 1917 by the Army Group Commander Field Marshal Prince Rupprecht of Bavaria as a large-scale attack either carried by itself or as an attack to relieve pressure on the German Front. Rupprecht's Army Group held the German Front in Flanders and Picardy; his command covered the Belgian coast to Ypres and on to Armentières.The operation was given the codename of "George" and plans were submitted for an offensive attack between Ypres and Bethune. The breakthrough would be made in the British Front just south of the Belgian-French border in the Lys river area with the intention to get past the Allied Front there and advance to Hazebrouck. This would divide and cut the British Second Army near the Lys river away from the British Army in Artois. The British-held rail centre of Hazebrouck would be captured and the British troops in Belgian Flanders could sent westwards and stuck on the Belgian coast. The operation would, however, only be possible to start from April.
