As the task force moved into position, the approaches to the beach were marked and cleared during the darkness, and at 06:00, an hour and 45 minutes prior to H-Hour, a heavy naval bombardment began, with the cruisers engaging targets around the airfields, as well as around the beaches and towards Target Hill. As H-Hour approached, the escorting destroyers also joined in the bombardment, followed by a carefully co-ordinated aerial bombing raid with five squadrons of B-24s, and one squadron of B-25s, attacking Target Hill. The first wave of assault troops disembarked from the APDs and were loaded into 12 Landing Craft, Vehicle, Personnel (LCVPs): six were bound for Yellow 1 and the other six for Yellow 2. While the APDs withdrew, the LCVPs began their run to the shore. After the B-25s made a final strafing run over the beach, two rocket-equipped LCIs stationed to the flanks fired onto the beach defenses.
