General MacArthur acting on aerial reconnaissance reports showing no signs of enemy activity on the Admiralty Islands presumed that they had been evacuated.
The six cruisers HMS Bedford, HMS Essex, HMNZ Achilles, HMS Argonaut, HMS Manchester and HMAS Perth anchored off Buna on Tuesday before setting sail after dark towards the Admiralty Islands with just under 2,000 extra passengers.
Thursday morning Australian and Royal Marine Commandoes assaulted a small, isolated beach on Los Negros at Hyane Harbour near the Momote airstrip, achieving a tactical surprise. The islands proved to be far from unoccupied and a furious battle ensued. There was fighting throughout the night as small groups of Japanese attempted to infiltrate the Commandoes beachhead.
At first light the Japanese launched another attack on the perimeter, but made little progress in the face of overwhelming firepower and close air-support. By lunchtime Friday the airfield was in Allied hand and 469 Japanese troops were killed. Of the commando force 47 men were killed, but those wounded approached the 600 mark.
On March 1st and 2nd, the US Pacific Fleet's Task Force 58, USS Enterprise, USS Essex, USS Ranger and USS Saratoga, attacked the main Japanese base at Truk.
