In early June in the face of the German assault, and with the collapse of the left wing of the French armies in Flanders, all fortress units attached to the Third Army were ordered to prepare for withdrawal to the south and west between 14 and 17 June The interval personnel of the SF Faulquemont were to be consolidated into a unit entitled the Groupement Girval, consisting of the 146th and 156th RIFs, together with units from the SF Sarre. On 13 June the troops of the field army in the intervals between fortifications began to withdraw towards the south, followed the next day by the fortress units designated for withdrawal. The withdrawal left the ouvrage garrisons in their positions to cover the withdrawal of the interval troops and the fortress infantry assigned to the divisions de marche. The Groupement Girval was assigned to the Third Army.[12]

Following the 15 June 1940 breakthrough by German forces through the Saar gap, the Germans advanced along the rear of the Maginot Line. The German 167th Infantry Division approached Kerfent, Bambesch, Einseling and Téting, now manned only by their individual garrisons, on 19 June. The 167th was a weak, inexperienced formation. However, the 167th's parent unit, Höheres Kommando XXXXV, had obtained extra 8.8cm high-velocity guns, which had proven particularly effective against Maginot positions in other sectors.[13] On the 20th the Germans assaulted Bambesch. After an initial infantry assault was repelled, a sustained barrage with 8.8 cm guns on Block 2 drove the defenders into the underground galleries. With further attacks on Block 3, the defenders risked entrapment and asphyxiation. Supporting fire from Kerfent was of limited use, since the petit ouvrage did not mount heavy weapons. Bambesch surrendered at 1900 hours.[14] German casualties were six wounded and one dead.[13]

The following day the Wehrmacht attacked Kerfent with 8.8 cm fire from a battery positioned atop Bambesch. Kerfent's cloches were hit by direct fire and Block 3 had to be abandoned after it was holed. The German batteries approached to within 100 metres (330 ft) to attack Block 2 using the cover of the nearby woods. A follow-up infantry assault ran into trouble, taking fire from Mottemberg and the Mottemberg Sud casemate in addition to Kerfent's machine gun turret. Despite this support, Kerfent was forced to surrender. The Germans suffered four dead and thirty wounded.[13][14][15][16]

On the 21st the Germans] attacked Einseling, which was more fortunate, as it was within range of Laudrefang's 81mm mortars, the only such weapons in the sector.[13] Einseling benefitted as well from a French ruse. French soldiers occupied nearby interval casemates at night, convincing the Germans that the casemates, which were evacuated by day, still harbored combat teams. The Germans divided their fire between the casemates and the ouvrage.[13] Laudrefang's fire, along with accurate fire from Einseling's lighter weapons, broke up a German artillery attack.[14] The defense was supported by the Quatre-Vents Nord casemate, which had been re-occupied by French teams.[13] The ouvrage survived until the Second Armistice at Compiègne took effect on 25 June, when it surrendered.[16] Téting fared similarly. After a disorderly German retreat[13] the infantry attacks were suspended in favor of an artillery barrage at Laudrefang, firing between 3000 and 3500 rounds at the ouvrage.[17] Compared to other German attacks on other ouvrages, the bombardment of Laudrefang was relatively ineffectual. While the concrete structure was badly damaged, it was not perforated, and the mortar turrets and cloches were not hit.[18] The ouvrage survived until the Second Armistice at Compiègne took effect on 25 June, when it surrendered.[16] The machine gun turret at Block 3 was used for testing of shaped-charge munitions.[19]

The 146th Fortress Infantry Regiment (the Faulquemont Regiment) held the Bois-des Chênes sub-sector. The regiment's third battalion sw action in September 1939, when it participated in an incursion in the Warndt Forest, with fighting on 9 September at Ludwiller. The regiment's interval troops were ordered to retreat on 14 May 1940, initially to the north, but on the 16th their orders were changed to have them regroup to the south on the Marne-Rhine Canal, where it was hoped that a defense could be established. However, some of the regiment's 21st battalion were captured near Domptail by elements of the German 198th Infantry Division and shot out of hand. The remainder of the 146th's mobile regiments surrendered near Saint-Dié on 23 June. The troops who remained in their positions surrendered on 2 July.[20]

The 156th Fortress Infantry Regiment was in charge of the Zimming sub-sector. In September 1939 the unit's third battalion participated in the Warndt incursion, from 8 September to 20 September. The regiment's interval troops were ordered to retreat on 13 June 1940, and the interval casemates followed suit on the 15th. The ouvrages remained manned. The regiment's mobile units were attached to the groupement Girval, which retreated to the south. The regiment surrendered on 22 June. The combat teams left behind at the ouvrages fought on, with Bambesch and Kerfent surrendering under fire on 21 June. The remaining ouvrages surrendered after the armistice on 2 July.[21]

The sector did not see significant action during the Lorraine Campaign of 1944, but Kerfent's observation block's cloche was used for weapons tests by the Americans.[22]

After the war, Kerfent's combat blocks were mostly left in their damaged state,[23] but the underground facilities were cleaned and maintained. From 1958 to 1961, prior to France's withdrawal from the NATO integrated command structure in the mid-1960s, Kerfent's underground portions and open surface areas were used by the Canadian 601st Communications Squadron as a communications center, supporting RCAF Station Grostenquin. A microwave antenna was erected on Block 2.[24][25] By 1970, Kerfent was listed for disposal,[26] and was acquired by the commune of Zimming. The military antenna was replaced by a civil television antenna.[25] Bambesch was stabilized after the war by military engineers and was acquired by the community of Bambiderstroff. The site was opened to the public on 31 August 1973.[15] Einseling, Téting and Laudrefang were in poor condition and were not chosen for renovation.[23]
