Ouvrage Laudrefang

The site was surveyed by CORF (Commission d'Organisation des Régions Fortifiées), the Maginot Line's design and construction agency, and was approved for construction in August 1931. It was completed at a cost of 24 million francs by the contractor Générale des Travaux Publics.[1] The petit ouvrage[nb 1] was originally planned as a gros ouvrage with fourteen blocks The project was scaled back, and Block 3 was not connected to the main ouvrage. A second phase was to connect it, and to provide a separate entrance block.[4] Even as a petit ouvrage it mounted the heaviest armament in its sector, with 81mm mortars.[5]

Laudrefang comprises five infantry blocks. Blocks 1, 2 4 and 5 are linked by deep underground galleries, which also provide space for barracks, utilities and ammunition storage. The galleries are excavated at an average depth of up to 30 metres (98 ft).[6]

• Block 1: Infantry block with two automatic rifle cloches (GFM), one twin machine gun embrasure (JM), two 81mm mortar embrasures and one machine gun/anti-tank gun embrasure (JM/AC47). The two-level block was heavily damaged by German shellfire.[7]
• Block 2: Infantry block with two GFM cloches and one retractable twin machine gun turret.[8]
• Block 3: Infantry block with two GFM cloches, one retractable twin machine gun turret, one twin machine gun embrasure, two 81mm mortar embrasures and one JM/AC47 anti-tank gun embrasure. The mortars are on a lower level, firing out of the ditch in front of the embrasures.[9]
• Block 4: Infantry/emergency exit block with two GFM cloches and one grenade launcher cloche (LG).[10]
• Block 5: Infantry block with one GFM cloche and one observation cloche (VDP). The block and cloches show the marks of German attack.[11]

The unbuilt blocks of the gros ouvrage would have included separate personnel and munitions entries, two 75mm gun turrets and a 135mm gun turret.[4]

The 1940 manning of the ouvrage under the command of Captain Gustave Cattiaux comprised 267 men and 8 officers of the 156th Fortress Infantry Regiment.[4] The units were under the umbrella of both the 3rd and 4th Armies, Army Group 2.[12] The Casernement de Zimming provided peacetime above-ground barracks and support services to Laudrefang and other positions in the area.[4][13]

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 on 19 June. On 21 June 1940 Laudrefang supported neighboring ouvrages Einseling and Teting as they came under attack[5] with an estimated 5000 81mm mortar rounds.[14] The covering fire prevented the Germans from taking either. The German infantry attacks were suspended in favor of an artillery barrage at Laudrefang, firing between 3000 and 3500 rounds at the ouvrage.[15] 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.[16] The ouvrage survived until the Second Armistice at Compiègne took effect on 25 June, when it surrendered.[17] The machine gun turret at Block 3 was used for testing of shaped-charge munitions.[18]

After World War II, Laudrefang was in poor condition and was not chosen for renovation.[19]

The lower levels of Laudrefang are flooded by groundwater, and the entire ouvrage is abandoned.[7]
