Two weeks prior to D-Day, the battery was bombed by B-26 Marauders. Over 500 tons of bombs landed in the vicinity and two guns were made inoperable by the attack. On 5 June the RAF bombed the battery but caused minimal damage. On the morning of 6 June 1944, the battery shelled the Allied landing beach Sword. The officer commanding the Merville battery called in fire from Houlgate onto his own when it was being attacked by paratroopers.
