 The fort was attacked on 10 May 1940 and rendered ineffective in a few hours by a team of 75 men armed with new shaped-charge explosives.Ineffective Belgian defense of the fort's surface allowed the German assault team to use their explosive charges to destroy or render the fort's gun turrets and machine gun cloches uninhabitable.With Eben-Emael out of action, the Germans could attack the other new forts with more conventional means, continuing attacks from 10 May.
