Ouvrage Chesnois, also known as Ouvrage Chênois, is a gros ouvrage of the Maginot Line, located in the Fortified Sector of Montmédy, facing Belgium. The ouvrage lies between the towns of Montlibert and Thonne-le-Thil. It possesses six combat blocks. It is located between gros ouvrage Thonnelle and petit ouvrvage La Ferté. The position was sabotaged and abandoned by French forces that were ordered to retreat from the exposed position in June 1940 during the Battle of France. The ouvrage is now abandoned and sealed.
The site was approved in 1934. Work by the contractor Bringer & Tondu began in 1934 at a cost of 37 million francs. A planned second phase was to add a second artillery block. The rise in tensions between France and Germany in the late 1930s prevented the second phase from being pursued.
Chesnois is one of four positions in the so-called Tête de Pont de Montmédy, a salient in the French defensive lines along the Belgian border. The isolated area was one of the "New Fronts" to the west of the main Maginot Line, created to defend against the increased threat of a German advance through Belgium. The New Front positions suffered from restricted funding, as well as discontinuity in the fortification lines. Large distances between fortifications compared to earlier portions of the Line made mutual support between ouvrages difficult.
Chesnois is a gros ouvrage It is located in gently rolling open country. The underground galleries extend more than 2,000 metres (6,600 ft) from end to end.
The fortification's drain extends 365 metres (1,198 ft) from Block 7 and serves as an emergency exit.
A number of small blockhouses are associated with Chesnois, as well as several casemates:
None of these are connected to the ouvrage or to each other.
The 1940 manning of the ouvrage under the command of Captain Aubert comprised 316 men and 8 officers of the 155th Fortress Infantry Regiment. The units were under the umbrella of the 2nd Army, Army Group 1. The Casernement de Montmédy provided peacetime above-ground barracks and support services to Chesnois and other fortifications in the area.
In the initial stages of the Battle of France, Chesnois provided covering fire to its neighbor Ouvrage La Ferté on 17–18 May 1940. Chesnois ceased fire during a French counterattack late on the 18th and did not resume firing. La Ferté's garrison was killed and the position was lost on the 19th.
