Chronology of the actual landing operations on 22 April 1944.

Western Area, Tanahmerah Bay.

0500K/22, The Western Attack Group arrived in the transport area according to schedule and commenced lowering of boats and disembarking troops.

0600K/22, The naval bombardment of the two 8" cruisers (HMAS Australia and HMAS Shropshire and six destroyers () commenced until 0645K/22. All ships stood well in to insure good observation. 600 rounds of 8" and 1500 rounds of 5" and 4.7" were fired without response. The air bombardment was cancelled owing to the absence of any indication of the presence of the enemy.

0700K/22, Landings at Red Beach 1 and 2 were made according to schedule. No opposition was encountered although small parties of Japanese were found in the hills behind Red Beach 2. Landings of troops and supplies continued on this day as scheduled and without enemy air or naval reaction.

Central Area, Humboldt Bay.

0500K/22, The Central Attack Group arrived in the transport area according to schedule and troops were disemraked rapidly and the landing craft stood toward the beach as scheduled.

0600K/22, The naval bombardment was conducted according to plan, three light cruisers (USS Phoenix, USS Nashville and USS Boise) and six destroyers ( USS Hutchins, USS Bache, USS Beale, USS Daly, USS Abner Read and USS Bush) delivered intense fire against the assigned targets until 0645K/22.

0645K/22, Naval aircraft delivered effective bombardment and conducted strafing missions on Beaches White 1 and 2.

0700K/22, Assault waves hit the beaches and quickly secured both sides of the entrance to Jautifa Bay. The landing came as a complete surprise and the Japanese abandoned their beach defences, rifle pits and weapons at the commencement of the naval bombardment. Sporadic resistance was encountered later in the day but the assault force secured the heights overlooking Challenger Cove, the tracks between Hollandia and Pim, Leimok Hill and Pim itself by nightfall. Unloading of LST's and transports progressed favourably despite the congested beach area. No enemy reaction was made to the Allied operations.

Eastern Area, Aitape.

0100K/22, The high speed minesweepers proceeded ahead of the Eastern Attack Group to sweep the transport area. The YMS minesweepers were slow in leaving formation and due to rain squalls, did not arrive in the transport area in sufficient time to complete sweeping operations before the arrival of the transport group. The DMS's were able to make one sweep before the transports arrived in the area.

0500K/22, The Attack Group arrived in the transport area as scheduled and the transports commenced lowering their boats and disembarking troops. As soon as loaded, the landing craft from the high speed transports formed on the SC's which were used as control vessels, and proceeded towards the beach.

0600K/22, The naval bombardment commenced and continued until 0630K/22, at which time the naval air delivered a bombardment on previously assigned targets, followed by a strafing attack on the beach until 0640K/22.

0645K/22, Two SC's, fitted with rockets and stationed on either flank on the landing craft approaching the beach, delivered their fire as the landing craft approached the beach and landed. Due to the difficulty in identifying the proper beach, the landing was made about 800 yards to the eastward of Blue Beach 1 at a small village called Wapil. The landing was made without oppostiion and only slight opposition developed later. It is believed that the landing was a complete surprise as breakfast was found on the stoves cooking and in several huts clothes were left by the bunks were Japanese left hurriedly. No enemy air or naval reaction was encountered in the initial landings.

The day of the landings was set at 1 July 1945, which was known as 'Fox' day. But as usual before a landing operation a period om minesweeping and bombardments preceeded the landings. We deal with these operations first.

The mission of the minesweepers was to clear the channels, approaches, anchorages, landing beaches and other designated areas of Allied and enemy mines prior to 'Fox' day in Balikpapan Bay, Borneo, NEI, to allow safe passage for the Balikpapan Attack Group.

Enemy minefields were reported off shore southeast of Balikpapan and also across the harbour entrance. Sutstantial enemy ground forces and many coast defence and duel purpose guns were known to be present defending the beaches. The enemy was expected to make every effort to harass and repulse the pre-'Fox' day operations.

Extensive Allied minelaying activity was conducted by RAAF Caralinas between February and October 1944 in Balikpapan Harbour and approaches. Of the total of 126 Allied infuence mines planted a possible 93 were still assumed to be active and requested sweeping prior to the landings on 'Fox' day. Due to the quantity and types of Allied mines present in the area it was agreed that a minimum of 16 days would be required to provide an approach chennel and to cover fire support areas to a reasonable degree of safety for landing operations to be conducted.

Minesweeping operations pre-'Fox' day

On 11 June 1945 ('Fox' day-20), at 0700I Oboe II, 'A' echelon got underway from Morotai for Balikpapan. The following vessels were part of this echelon.

Around 0720I/14, all groups joined in position 01°01'N, 119°38'E. USS Smith and USS Drayton then departed for Morotai. The other ships then set course for the operations area.

At 0642I/15, TU 78.2.92 arrived at the 100 fathom curve due east of the objective. YMS commenced streaming minesweeping gear and began sweep of apporach track for moored and acoustic mines in wedge formation. USS Cofer, USCG Gualala and TG 74.2 following them into swept water. At 1324I/15 the right and left flank of the YMS formation proceeded independently as had been planned. At 1622I/15 the right and left flank reformed wedge formation and commenced sweeping the approach track on an easterly course. At 2222I/15 sweeping ceased and the gear was recovered at the 100 fathom curve. All results of sweeping were negative.

At 0650I/16, the YMS Unit was detached to carry out assigned moored, magnetic and acoustic exploratory sweep of the fire support areas. At 0901I/16, minesweeping LCVP's commenced exploratory sweep of reported Japanese minefields. They returned at 1425I/16 from their minesweeping operations. At 1915I/16, all sweeping ceased and the YMS also retired for the night. Again no mines were swept this day.

At 0625I/17, minesweeping operations commenced in the fire support areas. These operations ceased at 1905I/17 when the YMS retired for the night. All results were again negative.

At 0630I/18, minesweeping operations commenced in the assault and close fire support areas. At 1253I/18, USS YMS-50 exploded an allied influence mine under her bow and was seriously damaged. At 1300I/18, USS YMS-50 was taken under fire by enemy shore batteries. The cruiser support group opened up with counter battery fire. At 1312I/18, LCVP's from USS Cofer proceeded to the rescue of personnel and also attempted to tow USS YMS-50. At 1448I/18, the LCVP's were also taken under fire and the attempts to tow USS YMS-50 were abandoned. All personnel was rescued. USS Denver then opened fire on the hulk of USS YMS-50 which then finally sank. At 1815I/18, minesweeping operations ceased and the YMS retired for the night. At 1855I/18 a Japanese float plane (Pete) closed TU 78.2.92, USS Cofer opened fire. The Combat Air Patrol took up chase of the aircraft. No further enemy air activity was reported. One influence mine was swept which damaged USS YMS-50.

At 1658I/22, the YMS again came under fire. They retired for the night at 1956I/22. No mines were swept on this day.

At 0530I/23, YMS commenced operations in assault and close support areas. At 1006I/23 they again came under fire from shore batteries. USS YMS-364 was struck by an enemy shell which failed to explode. At 1310I/23, USS YMS-368 was damaged by a mine explosion. She was taken in tow by USS YMS-335 and they departed for Tawi Tawi. At 1515I/23, shore batteries again opened fire on the YMS. No damage was sustained. At 1841 the YMS retired for the night. Again no mines were swept on this day.

At 0540I/24, YMS commenced scheduled operations in the assault area. USS Scout with 6 YMS conducted a moored sweep of the approach track to broaden the existing swept channel. At 1253I/24, USS YMS-9 reported for duty with TU 78.2.9. The TU came under sporadic fire from shore batteries during the day. No damage was sustained. At 1920I/24, TU 78.2.9 units retired for the night. Once again no mines were swept during this day.

At 0530I/25, YMS commenced scheduled operations in assault lane and close support area. At 0905I/25, the leading YMS were taken under fire by shore batteries but no damage was sustained. At 1105I/25, USS YMS-52 exploded an influence mine. At 1343I/25, USS YMS-365 detonated an influence mine which damaged her sweep. She retired from the area to effect repairs. Also YMS-39 detonated one influence mine and cut one moored mine in her sweep which was sunk by gunfire. At 1845I/25, TU 78.2.9 proceeded to the anchorage area of Balikpapan. Three influence and one moored mine were swept during the day. At 2030I/25 they came under attack by four enemy aircraft.

At 1343I/26, USS YMS-365 detonated an influence mine with magnetic sweep. At 1424I/26, USS YMS-365 exploded a mine, thought to be of influence type, directly beneath her. The keel was broken amidships. USS YMS-364 proceeded to remove her survivors. All personnel was saved. USS YMS-196 joined in the rescue and opened fire on the hulk of the damaged minesweeper which resulted in her bow section being sunk. The stern finally sank at 1645I/26. At 1547I/26, USS YMS-39 exploded a mine, believed to be an Allied magnetic mine. Her superstructure disintergrated and the vessel capsized and sank in less than one minute. Two additional mine explosions occurred in short succession the first approximately 100 yards abean and the second near electrode of long log. USS YMS-196 proceeded to rescue the survivors. Three of the crew were killed and one was missing. LCVP's from USS Cofer and USS Schmidt assisted in the rescue of surivors from USS YMS-39 and USS YMS-365. At 1855I/26, minesweeping ceased and the minesweepers proceeded to the anchorage. Six influence and three moored mines had been swept. Destroyers took fire support stations on this day to render close support during sweeping operations. Further enemy gunfire directed against the minesweepers was sporadic and inaccurate.

At 0610I/27, YMS commenced scheduled operations in the assault area. At 1310I/27, USS YMS-392 detonated an influence mine without sustaining damage. At 1840I/27, minesweeping operations ceased and the minesweepers proceeded to the anchorage. One influence and one moored mine were swept on this date.

At 0614I/28, YMS commenced scheduled operations in the assault area. At 1405I/28, USS YMS-47 exploded an Allied influence mine under her stern. A large hole was the result and the after compartments were flooded. USS YMS-366 and USS YMS-49 assisted by LCVP's from USS Cofer, USS Kline and USS Schmitt succeeded in rescuing all personnel and in towing USS YMS-47 out of the mine field. USS YMS-47 was taken alongside USS Scout for pumping and emergency repairs. Although the after deck was awash the engine room compartments were pumped out and the vessel stayed afloat. At 1920I/28, minesweeping ceased and the minesweepers returned to the anchorage. two influence mines were swept on this day, one of which damaged USS YMS-47.

At 0610I/29, YMS commenced scheduled operations in the assault area. These operations were ceased at 1850I/29 when they returned to the anchorage. Four moored contact mines were swept on this date.

YMS again commenced minesweeping operations in the assault area on 30 June [no time given in the report but must have been after dawn.] At 0945I/30, USS YMS-314 exploded an Allied influence mine about 100 feet astern. She sustained minor damage. At 1300I/30, USS YMS-65 and USS YMS-269 reported for duty with TU 78.2.9. At 1927I/30, minesweeping operations ceased and all YMS returned to the anchorage. One influence and three moored contact mines were swept this date.

At 1815I/1, USS YMS-84, USS YMS-224 and USS YMS-367 reported for duty with TU 78.2.9. At 1917I/1, minesweeping operations ceased for the day and the YMS returned to the anchorage. One moored mine was swept on this day. Total to this date, 15 Allied influence mines and 13 enemy moored contact mines were swept.

Pre-'Fox' day operations by Underwater Demolition Teams.

At 1700I/20, the temporary formed TU 78.2.93 departed Morotai for the operations area. This TU was to render close in fire support to the Underwater Demolition Teams during their pre-invasion operations of destroying underwater obstacles in the landing areas. These opertions would cover a day of six days in which reconnaissance and three days in which obstacle demolition operations were successfully carried out. TU 78.2.93 was made up of USS LCS(L)-30 (with COMLCS(L)GR 1, Lt.Cdr. W.F. Hunt, USNR on board), USS LCS(L)-8, USS LCS(L)-28, USS LCS(L)-29, USS LCS(L)-41, USS LCS(L)-43, USS LCS(L)-44 and USS LCS(L)-48. Taking passage with them from Morotai were also USS Schmitt, USS YMS-9 and USS Mango.

Around 1100I/24, TU 78.2.93 entered the Balikpapan area and reported to CTU 74.2 and 78.2.9 for duty. No assignment was given for the remainder of the day.

Around 0715I/25, The LCS(L) were in position to give fire support for underwater demolition work in the alternate landing areas at Manggar and Manggar Ketjil. A heavy concentration of 3", 40mm and 20mm was delivered into the immediate beach areas to eliminate, if possible, any sniper and machine gun positions. At 0800I/25, when the swimmers were taken into the beach, the fire was decreased and was concentrated in the tree tops along the beach. By 1000I/25 the reconnaissance was completed and all units retired and anchored.

Pre-dawn on the 26th, all ships of TU 78.2.93 got underway towards the Manggar Ketjil area to support obstacle demolition activities of the Underwater Demolition Teams. At 0700I/26 ships on station commenced strafing the beach. Between 0700 and 0820 hours, when swimmers embarked, fire was ceased several times to allow low level air strikes to be carried out. At 1025I/26, swimmers completed their assignment and charges were set off. Shortly thereafter units withdrew from a successful days work and anchored as before.

At 0430I/27, ships got underway and proceeded towards the assault beach at Klandasan. The passage was through unswept and hazardous water and a maximum speed of five knots was maintained at all times. To insure safe navigation the USS Stevens maintained an accurate radar plot and transmitted instructions via voice radio.
