Ouvrage Michelsberg, one of theMaginot Line fortifications, formed part of theFortified Sector of Boulay as well as the fortified region ofMetz. Theouvrage is located inMoselle (département) between the towns ofDalstein and d'Ebersviller, about 23 km fromThionville. It is located betweengros ouvrageMont des Welches andpetit ouvrageHobling, facingGermany. Michelsberg did not see significant action in theBattle of France until June 1940, when it was attacked from the rear by German forces that had bypassed the Maginot Line. It successfully resisted these attacks, but was compelled to surrender in accordance with the25 June 1940 armistice. After theSecond World War it was renovated as aCold War fortification against a potential Soviet invasion, then abandoned. It is now operated as a museum, and may be visited.
Michelsberg was approved for construction by the Commission d'Organisation des Régions Fortifiées (CORF), the Maginot Line's design and construction agency, in April 1930 and became operational by 1935,[1] at a cost of 56 million francs.[2] The contractor was Gianotti of Nice.[3] Unlike virtually all other Maginot positions, theouvrage does not have a drinking water well inside the position: the intended well was dry, forcing theouvrage to rely on a well outside.[4]
Michelsberg is agros ouvrage[nb 1], arranged in a linear fashion along a central underground gallery connecting the single combined personnel/ammunition entry block to the rear with the combat blocks about 800 metres (2,600 ft) to the east. It lacks a central "M1" ammunition magazine.[7] It does possess an electrified 60 cm internal rail network, used to move supplies and munitions within theouvrage.[8] The galleries are excavated at an average depth of up to 30 metres (98 ft).[9]
Apart from the emergency egress cloche, Michelsberg also features a false turret.[16]
In addition to the connected combat blocks, a series of detachedcasemates and infantry shelters surround Michelsberg, including
The manning of theouvrage in June 1940 comprised 472 men and 19 officers of the 164th Fortress Infantry Regiment and the 153rd Position Artillery Regiment, commanded by Commandant Pelletier. The units were under the umbrella of the 42nd Fortress Corps of the 3rd Army, Army Group 2.[7]
The Casernement de Férange provided peacetime above-ground barracks and support services to Michelsberg and other positions in the area.[7][18]
On 15 June the German 1st Army broke through the Line at theSaar and pushed west and east along the Line, enveloping the French armies, meeting forces of the German 16th Army that had gone around the Line in the west in May.[19] On 15 June Michelsberg fired 753 75mm rounds against the Germans.[20] Troops of the German 95th Infantry Division moved behind Michelsberg on 21 June, taking fire from blocks 3 and 6. Theouvrage repulsed a full German attack on 22 June 1940, with help from Mont des Welches and Hackenberg. German artillery hit Block 3's cloches and the façade of Block 2. Block 6 destroyed a German battery with artillery fire.[21] Following theSecond Armistice at Compiègne on 25 June, the Boulay sector's garrisons surrendered on 4 July 1940.[22] In the following years under German occupation, Michelsberg was used as a bombproof factory.[23]
During theLorraine Campaign only Hackenberg was occupied by the Germans; Michelsberg played no role in that campaign.[24] German forces did attempt to blow up the position when they evacuated, detonating explosives in the main gallery.[25]
Following World War II, interest revived in the use of the Maginot Line to defend against a possible Soviet advance through southern Germany. Funds were allocated for restoration of thegros ouvrages Work was limited to restoration of systems and improvements to existing armament.[26] The renovations did not include the command post or the barracks. By 1956, Michelsberg had been designated part of theMòle de Boulay, a strongpoint in the northeastern defenses against Soviet attack.[27] By the late 1950s interest in fixed fortifications was waning after France developed a nuclear deterrent. The money needed to maintain and upgrade the fortifications was diverted for the nuclear programs. Michelsberg was maintained for use by the Army until 1971 when it was placed in second-class reserve.[28]
After being abandoned, theouvrage was used between 1978 and 1988 for the cultivation ofmushrooms. Theouvrage was damaged and vandalized during this time. Renovations and repairs started in 1992 and are ongoing.[25] Since 1993 it has been protected by a charitable organization that allows visits on Sundays between April and September, inclusive.[29] The volunteers are also restoring the nearby Abri de Bilmette.[30]
