. . . "The Fortified Sector of Flanders (Secteur Fortifi\u00E9 des Flandres) was the French military organization that in 1940 controlled the section of the French border with Belgium between Lille and the North Sea. The sector was part of a system of fortifications that, in other sectors, included the Maginot Line. In the case of the Flanders sector, no large fortifications of the kind typified by the Maginot Line were built in the area. Fortifications were confined to almost two hundred blockhouses built during the 1930s, and some defensive inundations in the vicinity of Dunkirk. The Fortified Sector of Flanders was bordered on the east by the Fortified Sector of Lille It was quickly overrun by German forces during the Battle of France."@en . . . .
