Fortified Sector of Lille

In the case of the Lille sector, no large fortifications of the kind typified by the Maginot Line were built in the area.

In 1940 the Lille sector was under the overall command of the British Expeditionary Force, under the command of General Gort, which was in turn part of Army Group 1 under General Gaston Billotte.

A total of 65 blockhouses of eleven types were built, 23 infantry firing shelters (abris de tir) of four types, and nine turrets using small armored vehicle turrets and weapons.

[1] As many as 700 light blockhouses existed in all, many built by the British Expeditionary Force or adapted from German World War I positions.

[2] Other positions were built by the Main d'Oeuvre Militaire (MOM), Section Technique du Génie (STG) or the Fortifications de Campagne Renforcées (FCR).
