 On D @-@ Day at Gold , naval bombardment got underway at 05 : 30 , and amphibious landings commenced at 07 : 25 . High winds made conditions difficult for the landing craft , and the amphibious DD tanks were released close to shore or directly on the beach instead of further out as planned . Three of the four guns in a large emplacement at the Longues @-@ sur @-@ Mer battery were disabled by direct hits from the cruisers <unk> and <unk> at 06 : 20 . The fourth gun resumed firing intermittently in the afternoon , and its garrison surrendered on 7 June . Aerial attacks had failed to hit the Le Hamel strongpoint , which had its <unk> facing east to provide enfilade fire along the beach and had a thick concrete wall on the seaward side . Its 75 mm gun continued to do damage until 16 : 00 , when a modified Armoured Vehicle Royal Engineers ( AVRE ) tank fired a large <unk> charge into its rear entrance . A second casemated emplacement at La Rivière containing an 88 mm gun was neutralised by a tank at 07 : 30 .
