 border. The original plan for the position was for two phases of construction, resulting in a gros ouvrage provided with heavy artillery. The increase in tension between France and Germany in the late 1930s caused resources to be diverted elsewhere, and only the first three combat blocks were built. In 1940 the ouvrage was regularly bombarded, but not directly attacked by German infantry. When the French military divested itself of the majority of the Maginot fortifications, Mauvais-Bois was the second to be sold.

Design and construction

Mauvais-Bois was approved for construction in October 1931. It was completed at a cost of 11 million francs by the contractor Monod of Paris. The initial phase consisted of three combat blocks linked by deep underground galleries. In a second phase, Mauvais-Bois was to be expanded to function as a gros ouvrage, with two additional blocks mounting artillery, as well as remote entrances for munitions and personnel, and a larger network of deep underground galleries. The rise in tensions between France and Germany in the late 1930s prevented this second phase from being pursued.

Description

Three combat blocks were built at Mauvais-Bois, linked with underground galleries and with an incomplete gallery extending in the direction of the proposed artillery blocks and entrance blocks.

 for a broader discussion of the events of 1940 in the Crusnes sector of the Maginot Line.

In June 1940, the German 183rd Division considered a plan to penetrate the Maginot Line between Bois-du-Four and Mauvais-Bois, eventually rejecting it in favor of operations farther to the east. Mauvais-Bois saw mostly harassing attacks through June. After the 22 June 1940 armistice brought an end to fighting, the Maginot fortifications to the west of the Moselle did not immediately surrender. They maintained their garrisons through a series of negotiations. Mauvais-Bois, along with Bois-du-Four, Bréhain

. After the establishment of the French nuclear strike force, the importance of the Line declined, and in 1970 Mauvais-Bois was lowered in importance, allowing the use of formerly reserved areas around the ouvrage. Mauvais-Bois was the second Maginot ouvrage to be sold to the public.

Current

Mauvais-Bois is privately owned and is not accessible to the public. It is reported to be in poor condition, with all metal components salvaged. The Casemate de Morfortaine may be visited by appointment with the owner,who seeks to restore it.
