Question: Who was the French military organization that in 1940 controlled the section of the Maginot Line between the French border with Belgium and Maubeuge in the battle know as The Fall of France?

<P0-S0> The Battle of France, also known as the Fall of France, was the German invasion of France and the Low Countries during the Second World War. <P0-S1>  In six weeks from 10 May 1940, German forces defeated Allied forces by mobile operations and conquered France, Belgium, Luxembourg and the Netherlands, bringing land operations on the Western Front to an end until 6 June 1944. <P0-S2>  Italy entered the war on 10 June 1940 and attempted an invasion of France. <SEP> <P1-S0> The Fortified Sector of Montmédy ("Secteur Fortifié de Montmédy") was the French military organization that in 1940 controlled the section of the Maginot Line between Sedan and Longuyon, a distance of about 60 km . <P1-S1>  The sector was not as strongly defended as other sections of the Maginot Line, facing the southern Ardennes region of Belgium. <P1-S2>  Large portions of the Montmédy sector were defended by fortified houses, blockhouses, or casemates. <P1-S3>  The sector includes only four "ouvrages" of the type found in stronger sections of the Line. <P1-S4>  The weakly defended area in front of Sedan was the scene of a major breakthrough by German forces in the opening of the Battle of France. <P1-S5>  This was followed by a German assault on the Maginot Ouvrage La Ferté, which killed the entire garrison, the only such event on the Maginot Line. <SEP> <P2-S0> The Fortified Sector of Maubeuge ("Secteur Fortifié de Maubeuge") was the French military organization that in 1940 controlled the section of the Maginot Line between the French border with Belgium and Maubeuge, a distance of about 70 km . <P2-S1>  The sector was not as strongly defended as other sections of the Maginot Line Large portions of the Maubeuge sector were defended by blockhouses or casemates. <P2-S2>  The sector includes only four "ouvrages" of the type found in stronger sections of the Line, arranged in an arc to the north and east of the fortified city of Maubeuge, incorporating defenses from the First World War. <P2-S3>  The Maubeuge sector and the Fortified Sector of the Escaut were the final sections of the Maginot line to be authorized, and were termed the "New Fronts." <P2-S4>  In the Battle of France the large fortifications of Maubeuge successfully resisted determined German bombardments and infantry attacks, despite their failure to protect Maubeuge against the Germans, who had outflanked the defensive line and who assaulted the fortification lines from the rear. <P2-S5>  Surrender or evacuation came only after the positions were surrounded and cut off from any hope of reinforcement. <P2-S6>  One "ouvrage" and one pre-Maginot fortification have been preserved. <SEP> <P3-S0> The Fortified Sector of the Escaut ("Secteur Fortifié de l'Escaut"), also known as the Fortified Sector of the Schelde, was the French military organization that in 1940 controlled the section of the Maginot Line between the French border with Belgium and Valenciennes, a distance of about 30 km . <P3-S1>  Named for the Escaut River (more commonly known as the Schelde), the Maginot line in the Escaut sector consists of a single position, the "petit ouvrage" Eth, together with its supporting casemate Jeanlain, as well as an upgraded fort of the Séré de Rivières system, the Fort de Maulde. <P3-S2>  The remainder of the sector's fortifications consist of blockhouses and casemates arranged along a line of principal resistance about 2 km behind the frontier, with a second line on the edge of the Raismes Forest. <P3-S3>  The Escaut sector and the Fortified Sector of Maubeuge were the final sections of the Maginot line to be authorized, and were termed the "New Fronts." <P3-S4>  The Escaut sector was attacked during the Battle of France in late May 1940, resisting for a few days.
