Allied intelligence incorrectly assessed the Merville Gun Battery as housing heavy 150 mm guns capable of threatening the British landings at Sword Beach, 8 miles away. This threat assessment made neutralising the battery a critical D-Day objective, assigned to the 9th Parachute Battalion of 6th Airborne Division.
On 6 June 1944, the 9th Parachute Battalion attacked the battery with only 150 men after a scattered drop, capturing it at the cost of heavy attrition and reducing to 75 men. They found the guns were lighter Czech field howitzers and only partially disabled them before withdrawing, after which the Germans reoccupied and reactivated two guns.
The battery changed hands multiple times; a subsequent British Commando assault also failed to permanently disable the guns. German forces retained control of the battery until 17 August 1944, when they withdrew from the area. The engagement demonstrated the limits of dispersed airborne operations and the consequences of faulty pre-invasion intelligence.
