The Cruiser Covering Force and Fire Support Group departed Subic Bay on 24 April 1945. The minesweeping and hydrographic groups left Leyte on 22 April, joined at Zamboanga with other units coming from Malabang, Mindanao, and arrived at the objective on 27 April, and commenced minesweeping and hydrographic survey.

Minesweeping was difficult, because the many types of mines encountered and water conditions. The approach of the main force through preferred ' Track Baker ', south of Menoeloen Island, had to be abandoned because of the possibility that mines there had not yet been swept. This necessitated approaching though ' Track Able ' which afforded deeper water, but was much less in width. A red conical top buoy and a black top buoy of Japanese origin were found by the Hydrographic Group and left remaining, the latter buoy being the mid-channel. A buoy was planted at Point Whirlaway, buoy 2 south of Point Equinox, and buoy 3 was planted marking the break-off point for Tracks Able and Baker. Buoys 1 and 4 were also planted, as ordered, in positions as previously charted. The Hydrographic Group on the afternoon of ' Peter minus One day ' [Peter Day was 1 May 1945] installed fixed whire lights on the mid-channel buoy (Point Whirlaway) and numbers 2 and 4 buoys to aid the approach of the Attack Group. The harbour entrance range was lighted. Beach reconnaissance and marking of gaps through obstacles for assault waves and slots for LST's were completed on 30 April, without casualties, despite enemy mortar and machine gun fire from the beach. These groups retired each night prior to ' Peter Day ' at the objective.

On 27 April, ten motor torpedo boats arrived at Tawi Tawi and commenced operations on the east coast of northern Borneo the following day.

On 26 April 1945, the ' Pulau Sadau ' attack echolon daparted Morotai Straits. The Sadau attack echolon was known as Task Group 78.1.16 and was made up from ships from other units which were to rejoin their repective units on ' Peter Day '. The following ships were part of Task Group 78.1.16; USS Philip, USS PC-1120, USS LST-667 with USS LCT-1331 in tow, USS LSM-151, USS LSM-359, USS LSM-362, USS LCI(L)-172, USS LCI(L)-185 [???], USS LCI(L)-961, USS LCI(L)-1000, USS LCI(L)-1071, USS LCS-8 and USS LCS-48.

The main assault force departed on the 27th. Both echolons involved in the two separate assaults arrived in their respective areas off the designated beaches on time, the main assault force arriving one hour ahead of time to allow for the transit to the anchorage area of the last ships of the strung out approach formation through the narrow track ' Able '. The landings proceeded exactly as had been planned.

The preliminary naval bombardment was conducted by the Cruiser Covering Group on ' Peter Day ' [1 May 1945] with only the destroyers participating. This Group had also covered the Minesweeping Group in their activities from 27 April to 1 May. The Minesweeping Group on 27 April first made exploratory sweeps from the hundred fathom curve to ' Point Whirlaway ' with negative results. They then next obtained negative results in sweeps of Areas ' Fork ', ' Spoon ' and ' Knife ' to Point ' Baker '. One thousand yards north and south of the sides of Area ' Knife ', west of Point ' Baker ', four magnetic mines were swept. LCVP sweeps, the same day, explored Spatula and swept two chemical horned type mines south-west of Menoeloen Island, apparently newly laid. The Covering Force could not safely proceed west of ' Point Baker ', so did not. On 28 April, three magnetic mines in area ' Knife ', and seven enemy horned mines were swept in area ' Spatula ', south-west of Menoeloen Island. Two magnetic mines were still known to be in area ' Spatula ' and not yet swept. One of these magnetic mines self detonated near a YMS in area ' Knife ', west of ' Point Baker ', approach ' Track Baker ', after two days of sweeping, was still not considered safe for the passage of the Cruiser Covering Force.

On 29 April, magnetic sweeps were negative in areas ' Knife ' and ' Spatula '. A floating mine was sunk by gunfire four miles east of No.2 buoy. Nine additional enemy contact mines were swept south-west of Menoeloen Island. A one-thousand yard check sweep was made on both sides of ' Approach Track Baker '. Area ' Plate ' was swept within 1200 yards of the beaches and the LCVP's made two sweeps within 400 yards of the pier, all negative. By this time, five magnetic mines in area ' Knife ' were still unaccounted for, as well as two west of the southern tip of Tarakan. Sweepers on 30 April were to continue their magnetic and acoustic sweeps in areas ' Knife ', ' Spatula ' and ' Plate ' and leave by the north channel (' Track Able ') alone. The cruisers could not yet safely venture into area ' Knife '.

On 30 April, two influence mines were swept west of the south tip of Tarakan, and two additional enemy mines south-west of Menoeloen Island were swept after the landing and fire support parties had passed through route ' Baker '. Later, one of the fire support destroyers, USS Jenkins, on retiring, struck a mine 1000 yards off the center of ' Track Baker '. The sweepers swept two more mines in ' Approach Track Baker ' immediately after this incident. Five ' influence ' mines were reported removed at an unknown location. Because ' Track Baker ' was now not considered safe, the sweepers concentrated on ' Track Able ' which was still found negative. That night the Attack Group safely transited ' Track Able ', as had been recommended, and began the assault on ' Peter Day ', 1 May 1945.

The Sadau Attack Force meanwhile had landed around 0800I/30 which was on shedule. They landed without opposition. The landings were completed two hours later.
