 The battery's reconnaissance and assault groups embarked on 1 June, and the first part of C Troop disembarked on Juno Beach at 14.00 on D-Day (6 June).However, attempts to land four S/L lorries of C Troop later in the day led to three becoming submerged, and offloading of equipment did not restart until the following day at Juno and Sword Beaches, still under fire.By the end of D + 1 the battery had three lights in action against enemy raiders.
