Polish Navy Operation Neptune 1944-06-06 Coast of Normandy The ship saw action at the Normandy Landings as part of Operation Neptune, shelling German shore batteries at Colleville-sur-Orne and at Trouville (Sword Beach) from a distance of four kilometers. A near miss by a German 105 mm (4 in) shore battery gun wounded three sailors. She withdrew under cover of Ramillies and Roberts, whose fire destroyed the battery. In the evening of D-Day, she moved to Juno Beach sector, to support the advancing Allied troops. The following day the ship shelled German positions in and around the town of Caen.
However, on 8 June a communication systems failure prevented the ship from further bombardment and it was not until late at night that she again opened fire against the German 21st Panzer Division near Varaville. The following day she took part in an artillery duel with a shore battery at Houlgate, after which she returned to Portsmouth for refueling and supplies. Between 12 June and 17 June, she again shelled German positions near Caen, Gouneville, Lébisey, and Varaville. During that time she also evaded a torpedo attack by an unknown submarine. On 18 June she was bound for Portsmouth escorting Nelson which had struck by a mine.
