Ouvrage Einseling is a lesser work (petit ouvrage) of the Maginot Line. Located in the Fortified Sector of Faulquemont, the ouvrage consists of one infantry block, and is located between petits ouvrages Bambesch and Laudrefang, facing Germany. Einseling faced a determined German attack on 21 June 1940, during the Battle of France. Unlike its less fortunate neighbors to the west, Einseling was able to resist the attack with help from Laudrefang, its neighbor to the east. The ouvrage survives in a heavily battered state, with its lower levels flooded.
