Ouvrage Ferme Chappy, Military fortress of the Maginot Line in Viviers-sur-Chiers, France

Ouvrage Ferme Chappy is a petit ouvrage of the Maginot Line at Viviers-sur-Chiers, with two surface combat blocks linked by deeply buried galleries. Block 1 served as the entry and as a double infantry casemate flanking east and west, armed with two JM/AC47 embrasures, two JM embrasures, one JM cloche and two GFM cloches, one of them an observation post. Block 2 is an infantry turret block with a machine gun turret, a JM cloche and a GFM cloche. Underground are magazines, a barracks and a power plant with two 35-horsepower Renault generators.

Approved in April 1932 and completed for 11 million francs, Ferme Chappy was attacked on 21 June 1940 by the German 161st Infantry Division. Artillery from Ouvrage Fermont helped repel the assault, and the garrison surrendered on 27 June after negotiations led by Commandant Pophillat of Latiremont. The Germans later removed the machine gun turret and interior fittings.

The farm adjoining the ouvrage gave it its name, and its buildings still stand almost directly above the underground barracks and entry. The position was held in June 1940 by 109 men and three officers of the 149th Fortress Infantry Regiment under Lieutenant Thibeau, with the 152nd Position Artillery Regiment. Soldier Raymond Lebrun, serving the JM cloche of Block 1, was killed by a shell fragment during the 21 June attack.

The ouvrage is private property, owned by the farmer whose land covers the underground barracks, and it is not open to the public. It stands beside the farm buildings just east of Longuyon, in the Crusnes valley; the surface blocks can be seen from outside, but entry requires the owner's permission.

The ouvrage takes its name from the adjoining Ferme Chappy, whose buildings sit almost directly on top of the underground barracks and entry. The farm remained in private hands after the army sold the site, and the ouvrage is now the property of M. Peiffert, who owns the farm. It is not open to the public.
