Fortified Sector of Thionville
Encyclopedia
The Fortified Sector of Thionville (Secteur fortifié de Thionville) was the French military organization that in 1940 controlled the section of the Maginot Line
immediately to the north of Thionville
. The sector describes an arc of about 25 kilometres (15.5 mi), about halfway between the French
border with Luxembourg
and Thionville. The Thionville sector was the strongest of the Maginot Line sectors. It was surrounded but not seriously attacked in 1940 by German forces in the Battle of France
, whose main objective was the city of Metz
. Despite the withdrawal of the mobile forces that supported the fixed fortifications, the sector successfully fended off German assaults before the Second Armistice at Compiègne. The majority of the positions and their garrisons finally surrendered on 27 June 1940, the remainder on 2 July. Following the war many positions were reactivated for use during the Cold War
. Four locations are now preserved and open to the public.
The Thionville sector was part of the larger Fortified Region of Metz
, a strongly defended area between the Ardennes
to the west and the Sarre valley to the east. The Metz region was more important during the planning and construction phase of the Maginot Line than it was in the operational phase of the Line, when the sectors assumed prominence. The Fortified Region of Metz was dissolved as a military organization on 18 March 1940.

, under the command of General Charles Condé, which was in turn part of Army Group 2 under General André-Gaston Prételat
. The SF (secteur fortifiée) Thionville was commanded by General Cousse, then General Poisot from 1 January 1940. The command post was in the Fort d'Illange, south of Thionville. The interval troops, the army formations that were to provide the mobile defense for the sector, to support and be supported by the fixed defenses, were under the command of the Colonial Corps (Corps d'Armee Colonial (CAC)), General Fredenberg, commanding from the Château de Bétange. The Colonial Corps was in turn made up of the 2nd and 56th Infantry Divisions. Artillery support for the sector was provided by the 151st Position Artillery Regiment (Régiment d'Artillerie de Position (RAP)), which controlled both fixed and mobile artillery, commanded by Lt. Colonel Martin. The 2nd ID was made up of Class A reservists, while the 56th ID was a Class B reserve formation, not considered suitable for significant combat.

, aiming for Metz and Nancy. In the center, the German 1st Army had broken through at the Sarre
on 15 June. To the east, the Rhine was crossed on the same day. German armies were moving freely behind French lines with the goal of encircling France's field armies, capturing the cities of Alsace
and Lorraine
, and cutting off the fixed fortifications.
By mid-June, faced with the progressive collapse of the French First Army to the west, the interval troops began to pull back to avoid being encircled behind the Maginot Line. Measure A, issued by 3rd Army headquarters, called for the withdrawal of the interval troops on 15 June, protected by the casemates and ouvrages. Measure B was the withdrawal of artillery forces from the intervals late that day and into the 16th, protected by the ouvrages. Measure C was the withdrawal of all but skeleton forces from the fortifications. The forces left behind were to withdraw themselves by the 18th after sabotaging all equipment and weapons. Although the interval troops were able to temporarily escape, by the 17th the Thionville sector had been enveloped by the Germans from the east and west. Retreat was impossible for the fortress troops.
On 21 June General Wilhelm Ritter von Leeb
ordered all attacks against Maginot fortifications to stop, as a waste of resources. Action between the 21st and the date of the June 25 armistice was limited to sporadic shelling and, on the French side, to firing off ammunition at the Germans before it could be captured. Apart from determined German shelling of Block 5 at Rochonvillers, there were no significant attacks on Thionville sector ouvrages.
Following the armistice, brief negotiations undertaken by the commandant of Kobenbusch settled on a formal surrender for the garrisons west of the Moselle on 30 June. No such negotiations took place to the east until French officers received confirmation directly from General Huntziger that they were to surrender their fortifications. The eastern positions of the SF Thionville were surrendered on 2 July 1940

, again from 1961 to 1967. The French military continued to make use of Molvange until 1999. Soetrich saw a similar role in the 1960s. Rochonvillers was reactivated in 1980 as the wartime command center for the French First Army, operating in that role until 1998.

The Metz region was more important during the planning and construction phase of the Maginot Line than it was in the operational phase of the Line, when the sectors assumed prominence. The Fortified Region of Metz was dissolved as a military organization on 18 March 1940.
Concept and organization
The sector was planned to protect Thionville, an important industrial city, and by extension, Metz, just to the south. Construction began in most places in 1930, and was largely complete by 1935. A reinforcing line was planned to back up the Cattenom salient, which protruded to the north between Bois-Karre and Galgenberg, with Kobenbusch forming the point of the northward projection. Two casemate groups and the petit ouvrage du Beysel were proposed but were never built. The reinforcing role was partially assumed by three ex-German fortifications, the Forts de GuentrangeFort de Guentrange
