aerial bombing attack, destroying the gun turrets. The next day German ground forces attacked. Unable to mount an effective resistance, the fort surrendered. Present Flémalle was partly stripped of its equipment during the German occupation, and again by a salvager in the 1960s. The fort has been maintained by a preservation association since 1992, which has established a museum in the fort.
