Santmyers, USN) departed Milne Bay to support the landings at Arawa on New Britain (operation Director) as part of operation Dexterity which in itself was part of operation Cartwheel which objection was to neutralise the major Japanese base at Rabaul. Task Group 74.1 was the cover group for operation Director.

Task Group 74.2, made up of the light cruisers USS Nashville (Capt. H.A. Spanagel, USN) and USS Phoenix (Capt. A.G. Noble, USN), remained at Milne Bay at two hours notice for the moment.

Landing Force

The landings were to be carried out by Task Force 76 which was organised as follows;
CTG 76 (Headquarters Group) was on board the destroyer USS Conyngham. COMTASKFOR 76 was T/R.Adm. D.E. Barbey, USN.
Task Group 76.1 was the Transport Task Group of the amphibious transport HMAS Westralia and the dock landing ship USS Carter Hall.
Task Group 76.2 was the APD Task Group made up of seven APD's (APD = High Speed Transport).
Task Group 76.5 was the LCT Task Group made up of LCT from LCT Flot 7.

Task Group 76.10 was the Beachmaster Unit.

At 1530L/14, CTF 76 in USS Conyngham (T/Cdr. J.H. Ward, USN, with T/R.Adm. D.E. Barbey, USN on board) departed Buna for Arawe in company with the first and second attack echelons and their escorts. The other ships in the convoy were the following, amphibious transport HMAS Westralia (Cdr. A.V. Knight, RD, RANR(S)), dock landing ship USS Carter Hall (Lt.Cdr. F.J. Harris, USNR), high speed transports USS Humphreys (T/Lt.Cdr. Frank Dewey Schwartz, USN) and USS Sands (Lt.Cdr. L.C. Brogger, Jr., USNR), destroyers USS Shaw (T/Cdr. R.H. Phillips, USN, with COMDESRON 5, T/Capt. J.H. Carter, USN on board), USS Drayton (T/Cdr. R.S. Craighill, USN), USS Bagley (T/Cdr. T.E. Chambers, USN), USS Mugford (T/Cdr. H.G. Corey, USN), USS Mahan (T/Cdr. J.T. Smith, USN), USS Lamson (T/Cdr. J.R. Rubins, USN), USS Flusser (T/Cdr. J.A. Robbins, USN), USS Reid (T/Cdr. H.H. McIlhenny, USN, with COMDESDIV 10, T/Capt. C.D.

Blake, USNR), USS SC-981 (Lt.(jg) R.A. Campbell, USNR) and minesweeper USS YMS-51 (Lt. F.P. Allen, Jr., USNR).

1800L/14, after passing Cape Ward Hunt this force set course for Finschhaven as a deceptive move. Two Catalina flying boats provided A/S escort for the convoy.

1900L/14, the third attack echelon was scheduled to depart Cape Cretin. This echelon was made up of seven LCT's; USS LCT 172, USS LCT 174, USS LCT 176, USS LCT 374, USS LCT 378, LCT 380 and USS LCT 381. They were escorted by the patrol vessel USS SC-699 (Lt.(jg) J.W. Foristel, USNR), minesweeper USS YMS-70 (Lt. B.M. Brink, USNR) and coastal transport USS APc-4 (Lt.(jg) E.R. Edwards, USNR). USS LCT-378 and USS LCT-380 however were stuck on the beach and could not sail with the third attack echelon and remained behind but were able to departed around 1945L/14.

1900L/14, Task Group 74.1 passed north of Kiriwina Island and proceeded to the north-west at 27 knots.

2030L/14, the convoy with the first and second echelons changed its course to 040 to proceed to Arawe.

0100L/15, Task Group 74.1 was now about 25 nautical to the east of the first and second attack echelons. Task Group 74.1 remained 25 nautical miles to the east of the Arawe attack force until 0400L/15.

0315L/15, an enemy floatplane circled the convoy and dropped a stick of bombs near USS Reid. It was now apparent that the Allied movement had been spotted and that the element of surprise had been lost.

0400L/15, the convoy was led into the Transport Area by USS Conyngham. USS Humpreys and USS Sands had previously left the formation (around 0320L/15) escorted by USS Lamson and USS Shaw, they were to proceed to vicinity of Cape Merkus. HMAS Westralia and USS Carter Hall immediately began unloading. By 0500L/15, USS Cartel Hall had launched all her 41 DUKW's, Buffaloes and Alligators.

Task Group 74.1, the cover group, at this moment still 25 nautical miles to the east of the Arawe attack force commenced to sweep eastwards along the south coast of New Britain about 15 miles from the coast.

0500L/15, Task Group 74.1 had just increased speed to 27 knots and set course for a position to the north of Kiriwina Island when HMAS Warramunga got a sound contact and dropped a full pattern of depth charges on it. The attack could not be followed up as dawn was approaching and HMAS Warramunga was ordered to rejoin the Task Group.

0505L/15, HMAS Westralia and USS Carter Hall had completed unloading and then left the area for Buna escorted by the destroyers USS Bagley, USS Mugford, USS Drayton and the patrol vessels USS PC-1120 and USS PC-1129. They arrived at Buna around 1625L/15. HMAS Westralia, USS Carter Hall then immediately departed for Milne Bay, escorted by USS Conyngham and USS Bagley.

0515L/15, the leading wave of amphibious tractors was sighted heading full speed towards Arawe harbour, which if continued, would place them well ahead of schedule. USS SC-742, having learned from the leader that he had misunderstood his orders, ordered them to turn back to kill time.

0530L/15, the landing plan for Blue Beach called for three waves of five rubber boats each, but the troop commander desired to use four waves of four boats each. Due to the narrowness of the beach, this change appeared feasible and was accepted. Just as the first wave was about to land, Japanese, entrenched along and in the general vicinity of Blue Beach opened up with machine gun and mortar fire. The Japanese fire raked back and forth across all waves. The situation became most critical since it was not possible to determine the exact location of our troops, and it was considered better not to open ship counter battery fire until our troops could be located definitely.

0533L/15, USS Shaw proceed to a firing position where she was able to open fire without endangering our own troops. Two salvos silenced the Japanese. As far as is known, no troops reached the beach. The succeeding waves scrattered and returned to USS Shaw. After daylight survivors were recovered by destroyers and landing craft in the area.

USS SC-742 escorted the amphibious tractors of the first wave toward Orange Beach, via Pilelio Passage, but the succeeding waves failed to join up. The control LCVP was sent to herd them on, while the first wave stalled along losing time rapidly.

0615L/15, the Naval Gun Fire Support Group commenced bombardment on Orange Beach five minutes behind schedule, anticipating a delay in the first wave.

0625L/15, Six B-25 bombers reported on station in the Arawe Area for close support.

0637L/15, the naval bombardment ceased on Orange Beach and USS Shaw opened fire for three minutes on the ridge east of Cape Merkub. The bombardment did not draw enemy fire.

0645L/15, USS SC-742 fired 20mm on Cape Merkub as she entered the pass into Arawe Harbour. At the same time USS SC-981 laid a heavy and accurate rocket barrage on the beach and bluff east of the Cape. They drew no return fire.

0705L/15, USS SC-742 fired 49 rockets on Orange Beach as the first wave was 200 yards from the shore.

0708L/15, the B-25 bombers were ordered to bombard and stafe Cape Merkub and the area behind Orange Beach.

0710L/15, The first wave of amphibious tractors hit the beach, 40 minutes late, due partly to the late start, partly to the slowness in joining up, and partly to the unexpected current in Pilelio Passage.

0715L/15, Eight P-38 aircraft arrived on station as air cover over the landing area. USS Shaw was acting as fighter director ship, with USS Reid standing by.

0730L/15, Seven B-25 bombers comprising the second air support group relieved the first which departed to the eastward to find alternate targets to bomb on the track leading to Cape Bali.

0750L/15, The third wave of alligators landed, followed closely the fourth and fifth waves. The following three waves (ESB craft) were forced to lay to in Pelelio passage due to the slowness of the alligators.

0800L/15, Sixteen P-38's were on aircombat patrol over the landing area.

0810L/15, The sixth wave landed. The LCP's beached 30 yards from the shore and the troops waded ashore in three feet of water over the reefs.

0820L/15, USS Shaw, standing by as support off Blue Beach, picked up one officer and 19 men of the assault troops who failed to reach the beach.

0830L/15, The beachmaster reported the landing going well, but thst he was having difficulty in finding suitable landing points for boats.

0835L/15, Echelon number three arrived on schedule from Cape Cretin. While entering Pilelo Passage, numerous army personnel were picked up from the rubber boats and from the water. These men were the survivors of the unsuccessful attack on Blue Beach. At 0855, while waiting on the signal to beach, units of this echelon were subjected to an attack by 15 enemy dive bombers. Fortunately the craft had been dispersed and were thus able to maneuver and avoid serious damage. Three enemy planes were shot down.

0841L/15, USS Reid reported two groups of unidentified planes bearing 052°, 55 miles at 18000 feet and then lost them in the land echo in the vicinity of Gasmata.

0850L/15, Both USS Reid and USS Shaw regained radar contact of the enemy planes bearing 054°, 34 miles, course 190° and speed 180 knots. USS Shaw vectored our fighter patrol out at 23000 feet. USS Conyngham departed the Arawa area at 30 knots.

0857L/15, Our planes made contact with enemy planes.

0901L/15, USS Shaw reported enemy aircraft, 335°, 14 miles. This placed the enemy over USS Conyngham, which was indeed correct. Thirty or more planes were starting an attack. About 24 enemy Val aircraft released bombs on Arawe harbour. One Val bombed USS Conyngham but skillful maneuvering caused the bombs to miss, resulting in no damage.

0909L/15, USS Shaw reported enemy aircraft bearing 030°, 30 miles.

0926L/15, USS Shaw and USS Reid lost radar contact with the enemy aircraft at 080° at a range of 59 miles.

1600L/15, All destroyers of the gunfire support and escort group joined the return convoy south of Cape Ward Hunt. USS Conyngham proceeded independently to Buna.

1800L/15, Task Group 74.1, the cover group, which had spent the day to the north of Kiriwina Island now set corse to return to the Arawe area to protect the landing forces from possible enemy attack by surface ships but at 2000L/15, when it became clear that no enemy surface ships were to interfere with the landings, Task Group 74.1 was ordered to return to Milne Bay.

1830L/15, Echelon four departed Cape Cretin for Arawe. It was made up of six LCT's; USS LCT-82, USS LCT-88, USS LCT-384, USS LCT-386, USS LCT-387 and USS LCT-388. They were escorted by the patrol vessel USS SC-743 (Lt. W.W. Robinson, USNR) and the coastal transport APc-21 (Lt.(jg) W.J. Bates, USNR). Later the same evening they were ordered to return to Cape Cretin.

1900L/15, Echelon three completed unloading at Arawe and departed to return to Cape Cretin.

0630L/16, Echelon four again departed Cape Cretin for Arawa. It was made up of the same ships listed as above with the addition of LCT-378 and LCT-380. Also the minesweeper YMS-50 had joined as escort.

0800L/16, The cover group, Task Group 74.1 arrived at Milne Bay from the Arawe area. They now remained at Milne Bay at two hours readiness for sea.

1630L/16, Echelon four, en route from Cape Cretin to Arawe was attacked by twelve Japanese Val and Zeke aircraft but no damage was done by the enemy.

0130L/17, Echelon four, which was unloading at Arawe was submitted to intermittent air attacks during the night. The enemy attacks lasted until 0845L/17. At 0810L/17 around 50 enemy Val and Nate aircraft attacked by dive bombing and strafing. USS APc 21 was sunk by a direct hit at 0815L/17. USS YMS-50 sustained underwater damage by a near miss. USS LCT-88, USS LCT-378, USS LCT-380, USS LCT-384 and USS LCT-386 all sustained hull damage. USS LCT-380 had to be beached but was later able to return to Cape Cretin under her own power.

Sailing of echelon five was cancelled.

1900L/17, Echelon six departed Cape Cretin for Arawe. It was made up of six LCT's; USS LCT-142, USS USS LCT-166, USS LCT-245, USS LCT-248, USS LCT-391 and USS LCT-393. They were escorted by the patrol vessel USS SC-699, minesweeper USS YMS-49 (Lt. J.R. Lewis, USNR) and the coastal transport APc-15 (Lt.(jg) K. Goffigon, III. USNR).

2300L/17, Echelon four returned to Cape Cretin from the Arawe area only half unloaded.

0800L/18, Echelon six arrived at Arawe and unloaded as scheduled.

1900L/18, Echelon six, having completed unloading at Arawe, departed that place to return to Cape Cretin. During the unloading operations they had not been attacked. Fighter cover of the area had now been much inproved compared to the previous day.

0800L/19, Echelon six arrived at Cape Cretin from Arawe.

1700L/19, Echelon seven departed Cape Cretin for Arawe. This echelon was made up of six LCT's; USS LCT-61, USS LCT-177, USS LCT-179, USS LCT-183, USS LCT-184 and USS LCT-371. They were escorted by the patrol vessel USS SC-703 (Lt.(jg) R.M. Baird, USNR), minesweeper YMS-70 and the coastal transport APc-22 (Lt.(jg) V.G. Martin, USNR).

-------------------------------------------------------

1400L/24, The fifth echelon, made up of seven LST's; USS LST-452, USS LST-452, USS LST-22, USS LST-26, USS LST-454, USS LST-456, USS LST-457 and USS LST-465 departed Cape Sudest for the Cape Gloucester area via Cape Cretin. They were escorted by the destroyers USS Beale, USS Hutchins, USS Brownson and USS Daly. HMAS Reserve also accompanied this echelon.

1630L/24, Task Force 74, the cover force, departed Milne Bay.

0100L/25, The third echelon, made up of seven LST's; USS LST-466, USS LST-18, USS LST-66, USS LST-67, USS LST-68, USS LST-202 and USS LST-204 departed Cape Sudest for Cape Gloucester. They were escorted by the destroyers USS Drayton, USS Lamson, USS Bagley and USS Mugford.

0600L/25, Task Force 76's flagship for the operation, the destroyer USS Conyngham departed Cape Sudest for the Cape Gloucester area. With the flagship were the first and second echelons which were made up of the high speed transports USS Stringham, USS Kilty, USS Ward, USS Crosby, USS Brooks, USS Gilmer, USS Humphreys, USS Sands, USS Noa, the LCI(L)'s USS LCI(L)-30, USS LCI(L)-31, USS LCI(L)-34, USS LCI(L)-70, USS LCI(L)-71, USS LCI(L)-72, USS LCI(L)-73, USS LCI(L)-74, USS LCI(L)-226, USS LCI(L)-337, USS LCI(L)-338, USS LCI(L)-340, USS LCI(L)-342, USS LCI(L)-343, USS LCI(L)-344, [USS LCI(L)-28 (Lt.(jg) E.A. Winton, USNR) apparently was also with them though she is not listed in the Task Force originsation form for the operation]. They were escorted by the destroyers USS Shaw, USS Mahan, USS Flusser, USS Reid, USS Smith, patrol vessels USS SC-742, USS SC-981 and the minesweepers USS YMS-50, USS YMS-51 and USS YMS-70.

1130L/25, Task Force 74 cleared Cape Ward Hunt and began to overtake the attack echelons. It was the plan that Task Force 74 would be about 12 miles ahead of the leading echelon before dark and during the night approach would therefore be covering all the echelons which were following.

1600L/25, The fourth echelon made up of 12 LCT's and 16 LCM's departed Cape Cretin for Cape Gloucester. They were escorted by the patrol vessels USS PC-479, USS SC-637 and two PT-boats. This echelon was to land on Green Beach in the Western area.

2000L/25, When it was now just dark Task Force 74 was ahead of the leading echelon.

2120L/25, USS YMS-50 had to part company with the first en second echelon due to engine trouble. She was ordered to proceed to Cape Cretin.

2130L/25, the sixth echelon departed Cape Sudest for Yellow Beach, Cape Glouceter. It was made up of LST's USS LST-459, USS LST-168, USS LST-170, USS LST-171 and USS LST-458. They were escorted by the patrol vessels USS PC-1119, USS PC-1120 and USS PC-1122. The destroyers USS Flusser and USS Mahan were to join this echelon about 25 nautical miles south of Langemak Bay and shortly afterwards also USS Reid and USS Smith around 1600L/26.

0455L/26, the seventh echelon departed Cape Sudest for Yellow Beach, Cape Glouceter. It was made up of LST's USS LST-474, USS LST-467, USS LST-468, USS LST-470 and USS LST-475. They were escorted by the patrol vessels USS SC-703, USS SC-734 and USS SC-738. The destroyers USS Lamson, USS Drayton, USS Bagley and USS Mugford were to join this echelon near Langemak Bay.

0445L/26, Taks Force 74 split into Task Group 74.1 and 74.2 (see above) to enter their respective fire support areas.

0600L/26, As scheduled HMAS Australia, HMAS Shropshire, HMAS Warramunga and HMAS Arunta commenced bombarding the vicinity of Gloucester aerodrome. The objects of the bombardments were to destroy enemy installations and to prevent the enemy from reorganising counter measures to the landing. Also the enemy artillery was to be silenced. The bombardment was continued until 0720L/26 by which time over 700 round of 8" high explosive, nearly 900 rounds of 4.7" high explosive and nearly 100 rounds of 4" high explosive had been fired. There was no enemy opposition to this intense bombardment.

0625L/26, USS Nashville and USS Phoenix commenced bombarding targets on the western coastline of Borgen Bay,including targets in the vicinity of 'Yellow Beaches' where the assault landing would be made. This bombardment, with USS Bache joining in for ten minutes to fire 300 rounds of 5", continued until 0727L/26. Over 1600 rounds of 6" were fired by USS Nashville and USS Phoenix.

USS Flusser and USS Mahan intermittently bombarded 'Yellow Beaches' up to H-hour, firing a total of about 400 rounds of 5".

0700L/26, between 0700 and 0720 hours, five squadrons of B-24 bombers, from medium altitude, bombed targets in the Cape Gloucester area. As far as could be seen these bombers had no AA opposition. This was thought to be due the the effective naval bombardment of the area.

0728L/26, between 0728 and 0743 hours, four squadrons of B-25 bombers swept in from seaward and bombed and strafed the Yellow Beaches from very low altitude.

0743L/26, between 0745 and 0745 hours, rocket boats laid a creeping rocket barrage up the Yellow Beaches and from behind this barrage the main assault was made without opposition.

0750L/26, Green Beach at Tauali, had been similarly prepared by naval and air bombardment and here, too, the assault force got ashore without opposition.

Fighers on air alert were over the combat area soon after sunrise. The first fighter sortie was four flights (16 planes in total) but from 0800L/26, the air support plan allowed for 12 flights (48 planes) being continually over the combat area and other squadrons of fighters were on ground alert available on call.

0800L/26, HMAS Shropshire, which was the fighter direction shop for all fighter planes in the combat area, began tracking a large group of bogies approaching from the direction of Rabaul and it was thought that the enemy reaction was on its way. However these bogies crossed to southward over New Britain and a group of fighters sent down to southward saw the enemy planes retiring after attacking Awawe.

0830L/26, with the assault proceeding favourably, CTF 76 released Task Force 74 which then began a high speed retirement to west and south through Vitiaz Strait.

0840L/26, LST's of the third echelon beached on Yellow Beach and commenced unloading.

0900L/26, Four squadrons of heavy bombers attacked Target Ridge from medium altitude and at 0930L/26 four squadrons of attack bombers struck targets in the Gloucester-Borgen Area.

Shortly after Task Force 74 entered Vitiaz Strait, HMAS Shropshire radar detected two large groups of bogies coming in from the westward and these were reckoned to be an enemy strike from his New Guinea air bases. Additional fighters were summoned and in all 96 fighters planes were disposed to meet this attack. However at this time the radar was confused by land all round and the bogies were lost. At about the time these bogies were estimated by dead reckoning to be approaching an attacking position, Task Force 74 was in rain an temporary low overcast so that the force may have avoided detection, though it has not been ascertained exactly where these enemy groups did actually go.

0920L/26, The commander General Cape Gloucester Task Force departed USS Conyngham which then left the area for the Buna / Cape Sudest area. En-route she overtook the high speed transports of the first echelon which had already left the landing area. The LCI's of the second echelon also departed the landing area around this time, having retracted from the beach successfully.

1330L/26, The LST's of the third echelon retracted as scheduled to make room for the incoming echelon five. Echelon three had however not yet been completely unloaded. The delay in unloading had been due to the difficulty in preparing the dispersal area. The thick growth and soft ground behind the beach was the retarding factor. Approximately 100 tons of bulk and a few vehicles were returned to Cape Sudest but were later shipped back in following echelons.

1415L/25, USS Shaw, the fighter director ship in the Cape Gloucester area, picked up two large groups of enemy planes, one group bearing 010°, 65 miles and the other bearing 080°, 50 miles.

1430L/26, Task Force 74 was now south-east of Finschhaven, Task Unit 74.2.2 (four destroyers, see above) were detached to return to the Cape Gloucester area and during the night to carry out a covering patrol.

Around 1445L/26, an enemy air attack consisting of a large number of dive bombers with fighter escort and a group of high level bombers was made on our ships off Cape Gloucester. Fighter interception was made and is estimated to have shot down 56 enemy planes. However a number of dive bombers got through and attacked our ships. USS Brownson was sunk, USS Shaw was badly damaged by near misses and USS Lamson and USS Mugford were slightly damaged. USS LST-66 also sustained minor damage due to a near miss.

1530L/26, USS Lamson and USS Daly had picked up 34 and 163 survivors from the USS Brownson. These included 11 of the ships officers. While picking up the survivors USS Daly suffered some minor damage due to a heavy underwater explosion, most likely depth charges exploding on board the sinking USS Brownson.

1700L/26, A second air attack on our destroyers off Cape Gloucester developed. Approximately 50 enemy aircraft, 18 of which were torpedo carrying Bettys approached at low altitude. At least 13 were destroyed by fighters and 3 by AA gunfire from ships. No damage was sustained and it is believed that none of the enemy aircraft had been able to release torpedoes. This action ended the days air activity.

1800L/26, Echelon five (7 LST's), plus USS LST-466 from echelon three, departed Yellow Beach for Cape Sudest escorted by USS Hutchins and USS Beale. A total of about 200 tons of bulk stores were still on board. Departure was made on schedule as it was condidered to dangerous to navigate the reef during darkness.

1815L/26, Task Units 74.1.1, 74.1.2 and 74.2.1 arrived at Buna where they immediately refueled on completion of which they came short notice to proceed to sea if required.

2300L/26, the first echelon, made up of the high speed transports, USS Stringham, USS Kilty, USS Ward, USS Crosby, USS Brooks, USS Gilmer, USS Humphreys, USS Sands, USS Noa, arrived at Cape Sudest from the Cape Gloucester area.

2330L/26, USS Conyngham with CTF 76 on board, arrived at Buna from the Cape Gloucester area.

During the night of 26/27 December, Task Unit 74.2.2 carried out a covering patrol in the Cape Gloucester area without incident.

0740L/27, Task Unit 74.2.2 which was withdrawing from night patrol, was ordered to join the seventh echelon consisting of USS Drayton, 4 LST's and 3 SC's proceeding the the Cape Gloucester area. The radar intallation on board USS Drayton was defective. The fighter direction party was transferred at sea from USS Drayton to USS Bush.

0800L/27, the second echelon, made up of the LCI(L)'s, USS LCI(L)-28, USS LCI(L)-30, USS LCI(L)-31, USS LCI(L)-34, USS LCI(L)-70, USS LCI(L)-71, USS LCI(L)-72, USS LCI(L)-73, USS LCI(L)-74, USS LCI(L)-226, USS LCI(L)-337, USS LCI(L)-338, USS LCI(L)-340, USS LCI(L)-342, USS LCI(L)-343 and USS LCI(L)-344 arrived at Cape Sudest from the Cape Gloucester area.

0830L/27, the seventh echelon, made up of the LST's USS LST-474, USS LST-467, USS LST-468, USS LST-470 and USS LST-475 and escorted by the destroyers USS Drayton, USS Bush, USS Bache, USS Ammen and USS Mullany.

0900L/27, The fourth echelon made up of 12 LCT's arrived at Cape Cretin from Cape Gloucester escorted by the patrol vessels USS PC-479, USS SC-637 and SC-699.

1000L/27, Task Unit 74.1.2 (four destroyers, see above) departed Buna to carry out a night covering patrol to the north-eastward of Cape Gloucester.

1800L/27, Task Unit 74.2.2 and USS Drayton took up patrol off the reefs. During the night USS Mullany made three depth charge attacks on a sound contact with no observed results.

1800L/27, As four destroyers of Task Force 76 had been sunk or damaged, the destroyers of Task Force 74 were now assigned for temporary escort duty with Task Force 76.

2200L/27, Echelon 5 (7 LST's) and LST-466, escorted by USS Hutchins and USS Beale arrived at Cape Sudest from the Cape Gloucester area.

0300L/28, Task Unit 74.1.2 left patrol and retired towards Cape Cretin.

0400L/28, The fifth echelon, made up of USS LST-452, USS LST-452, USS LST-22, USS LST-26, USS LST-454, USS LST-456, USS LST-457 and USS LST-465 arrived at Cape Sudest from the Cape Gloucester area escorted by USS Beale, USS Hutchins and USS Daly.

0700L/28, The seventh echelon had completed unloading and by 0830L/28, it was retiring from the Cape Gloucester area escorted by Task Unit 74.2.2 and USS Drayton.

1430L/28, The eight echelon departed Cape Sudest for the Cape Gloucester area. It was made up of the high speed transports USS Stringham, USS Kilty, USS Ward, USS Crosby, USS Brooks, USS Gilmer, USS Humphreys, USS Sands and USS Noa. They were escorted by the destroyers USS Hutchins and USS Lamson and would later be joined by USS Bush, USS Bache, USS Ammen and USS Mullany.

1600L/28, Task Unit 74.1.2 departed Cape Cretin to make a high speed dash up towards the Cape Gloucester area to repeat the night covering patrol of last night and to return to Cape Cretin afterwards.

At 1700L/28, Task Unit 74.1.2 departed Cape Cretin to proceed to the southward to join the escort of the ninth echelon that was to proceed from Cape Sudest to the Cape Gloucester area. As HMAS Warramunga and HMAS Arunta were short of fuel they arrived at Buna around 2200L/29 where they took on board 100 tons of fuel from HMAS Australia and HMAS Shropshire respectively. They departed around 2330L/28 to rejoin the other two destroyers of their Task Unit which meanwhile had joined the ninth echelon.

2100L/28, The ninth echelon, made up of six LST's; USS LST-466, USS LST-18, USS LST-66, USS LST-67, USS LST-68, USS LST-202 departed Cape Sudest for the Cape Gloucester area. USS LST-204 was unable to retract and had to proceed to Cape Gloucester with the next (tenth) echelon. They were escorted by HMAS Warramunga, HMAS Arunta, USS Ralph Talbot and USS Helm although the two Australian destroyers only joined later as they first had to fuel (see above). The ninth echelon arrived at Cape Gloucester around 0700L/30. After unloading they departed for Oro Bay around 1300L/30 still escorted by the four destroyers from Task Unit 74.1.2 which then detached after having passed Cape Ward Hunt. The destroyers of Task Unit 74.1.2 arrived at Buna around 1800L/31 minus HMAS Warramunga which arrived at 2030l/31 having trouble with salt water contamination in her boiler feed water.

2200L/28, the sixth echelon, made up of USS LST-459, USS LST-168, USS LST-170, USS LST-171, USS LST-458 and escorted by USS Flusser, USS Mahan, USS Reid, USS Smith and the patrol vessels USS PC-1119, USS PC-1120 and USS PC-1122 arrived at Cape Sudest from Cape Gloucester.

At 1700L/28, Task Unit 74.1.2 departed Cape Cretin to proceed to the southward to join the escort of the ninth echelon that was to proceed from Cape Sudest to the Cape Gloucester area. As HMAS Warramunga and HMAS Arunta were short of fuel they arrived at Buna around 2200L/29 where they took on board 100 tons of fuel from HMAS Australia and HMAS Shropshire respectively. They departed around 2330L/28 to rejoin the other two destroyers of their Task Unit which meanwhile had joined the ninth echelon.

0650L/29, the eight echelon, made up of the high speed transports USS Stringham, USS Kilty, USS Ward, USS Crosby, USS Brooks, USS Gilmer, USS Humphreys, USS Sands and USS Noa escorted by the destroyers USS Lamson, USS Bush, USS Bache, USS Ammen and USS Mullany arrived at Cape Gloucester. Unloading was completed at 0930L/29 when they departed to return to Cape Sudest where they arrived around 2300L/29. USS Gilmer had on board 50 wounded Marines.

1400L/29, the seventh echelon arrived at Buna from Cape Gloucester. Task unit 74.2.2 was still with the seventh echelon.
