The Battle of Milne Bay (25 August – 7 September 1942), also known as Operation RE or the Battle of Rabi (ラビの戦い) by the Japanese, was a battle of the Pacific campaign of World War II. Japanese naval infantry, known as Kaigun Tokubetsu Rikusentai (Special Naval Landing Forces), with two small tanks attacked the Allied airfields at Milne Bay that had been established on the eastern tip of New Guinea. Due to poor intelligence work, the Japanese miscalculated the size of the predominantly Australian garrison and, believing that the airfields were defended by only two or three companies, initially landed a force roughly equivalent in size to one battalion on 25 August 1942. The Allies, forewarned by intelligence from Ultra, had heavily reinforced the garrison.
Despite suffering a significant setback at the outset, when part of their small invasion force had its landing craft destroyed by Royal Australian Air Force aircraft as they attempted to land on the coast behind the Australian defenders, the Japanese quickly pushed inland and began their advance towards the airfields. Heavy fighting followed as they encountered the Australian Militia troops that formed the first line of defence. These troops were steadily pushed back, but the Australians brought forward veteran Second Australian Imperial Force units that the Japanese had not expected. Allied air superiority helped tip the balance, providing close support to troops in combat and targeting Japanese logistics. Finding themselves heavily outnumbered, lacking supplies and suffering heavy casualties, the Japanese withdrew their forces, with fighting coming to an end on 7 September 1942.
The battle is often described as the first major battle of the war in the Pacific in which Allied troops decisively defeated Japanese land forces. Although Japanese land forces had experienced local setbacks elsewhere in the Pacific earlier in the war, unlike at Milne Bay, these earlier actions had not forced them to withdraw completely and abandon their strategic objective. Nor did they have such a profound impact upon the thoughts and perceptions of the Allies towards the Japanese, and their prospects for victory. Milne Bay showed the limits of Japanese capability to expand using relatively small forces in the face of increasingly larger Allied troop concentrations and command of the air. As a result of the battle, Allied morale was boosted and Milne Bay was developed into a major Allied base, which was used to mount subsequent operations in the region.
Background
Geography
Military situation
The Japanese thrust into the Pacific region had begun in early December 1941 with attacks against British and Commonwealth forces in the
Although the Japanese had been defeated in the Coral Sea, another attempt at capturing Port Moresby was anticipated. The Allied Supreme Commander of the South West Pacific Area,
The Commander in Chief of Allied Land Forces, General Sir Thomas Blamey, selected a garrison for Boston on 24 May. The troops were informed that their mission was only to defend against Japanese raids, and in the event of a major attack they would destroy everything of value and withdraw. The Boston project fell through, as a reconnaissance of the area gave an unfavourable report and Elliott-Smith suggested Milne Bay as a more suitable alternative site.[5][16] A party of twelve Americans and Australians set out to explore Milne Bay in a Consolidated PBY Catalina flying boat on 8 June. They were impressed by the flat areas, the roads and the jetties, all of which would ease airbase construction. On receipt of a favourable report from the party, MacArthur's General Headquarters (GHQ) cancelled Boston on 11 June and substituted Milne Bay.[15] Milne Bay was given the codename "Fall River".[17] The use of place names as code names proved to be unwise, as some supplies were mistakenly sent to the real Fall River, in Massachusetts.[18]
Prelude

Allies
The first troops arrived at Milne Bay from Port Moresby in the Dutch
Work on the first airfield, which became known as No. 1 Airstrip, had commenced on 8 June, with the area near Gili Gili being cleared by Papuan workers under the supervision of ANGAU and by US 96th Engineer Separate Battalion personnel. Company E of the 46th Engineers began working on it on 30 June. In addition to the runway, they had to build camouflaged dispersal areas for 32 fighters, taxiways and accommodation for 500 men. To support the airbase and the garrison, a platoon was diverted to working on the docks and roads.[23] Although the channels in Milne Bay allowed deep draught ships to approach within 40 feet (12 m) of the shore, they had to be unloaded onto pontoons and the stores manhandled onto vehicles, a labour-intensive process.[24]
Three
With No. 1 Airstrip operational, work began on two more airfields. Some 5,000 coconut trees were removed for No. 2 Airstrip, and the site was levelled and graded, but its use first required the construction of at least two 60-foot (18 m) bridges, so work moved to No. 3 Airstrip near Kilarbo. Its construction was undertaken by the 2nd Battalion of the US 43rd Engineers (less Company E), which arrived on 4 August.[23][24][27] That day Japanese aircraft began to bomb and strafe Milne Bay, focusing upon attacking the airfields and the engineers as they worked.[11] Four Zeros and a dive bomber attacked No. 1 Airstrip. One Kittyhawk was destroyed on the ground, while a Kittyhawk from No. 76 Squadron shot down the dive bomber. Following this, the Australians established a workable radar system to provide early warning. On 11 August, 22 Kittyhawks intercepted 12 Zeroes. Despite their numerical advantage, the Australians lost three Kittyhawks, while claiming four Japanese Zeros shot down.[28]
On 11 July, troops of the
Although malaria was known to be endemic in the Milne Bay area, precautions taken against the disease were haphazard. Men wore shorts and kept their sleeves rolled up. Their mosquito repellent cream was ineffective, quinine was in short supply and many men arrived without their mosquito nets, which were stowed deep in the ships' holds and took several days to unload. A daily dosage of 10 grains (0.65 g) was prescribed but Field's troops were told not to take their quinine until they had been in the area a week. By this time, many had become infected with the disease. The Director of Medicine at Allied Land Forces Headquarters was Brigadier Neil Hamilton Fairley, an expert on tropical medicine. He visited Port Moresby in June, and was alarmed at the ineffectiveness of the measures being taken to combat the disease, which he realised was capable of destroying the entire Allied force in Papua. He made sure that the 110th Casualty Clearing Station left Brisbane for Milne Bay with a fully equipped pathological laboratory and a large quantity of anti-malarial supplies, including 200,000 quinine tablets. However, some equipment was lost or ruined in transit, and the danger from malaria was not yet appreciated at Milne Bay.[31][32]
The 55th Infantry Battalion's companies were already badly afflicted by malaria and other tropical diseases, and were withdrawn and sent back to Port Moresby in early August,
With two brigades now at Milne Bay, Major General Cyril Clowes was appointed to command Milne Force, which was placed under the control of New Guinea Force, now commanded by Lieutenant General Sydney Rowell, on 12 August.[36] Clowes' headquarters was formed in Sydney at the end of July and was flown up to Milne Bay.[37] He arrived with some of his staff on 13 August, but had to wait until the rest arrived before he could formally assume command of Milne Force on 22 August. By this time there were 7,459 Australian and 1,365 US Army personnel at Milne Bay, of whom about 4,500 were infantry.[36] There were also about 600 RAAF personnel.[38]
Clowes assigned the inexperienced 7th Infantry Brigade a defensive role, guarding key points around Milne Bay from seaborne or airborne attack, and kept the veteran 18th Infantry Brigade in reserve, ready to counterattack.[39] Lacking accurate maps and finding that their signals equipment was unreliable in the conditions, the Australian command and control system consisted largely of cable telephones, or where there was not enough line available, runners.[40] The soft ground made movement by road and even on foot difficult.[41]
Japanese
Japanese aircraft soon discovered the Allied presence at Milne Bay, which was appreciated as a clear threat to Japanese plans for another seaborne advance on Port Moresby, which was to start with a landing at

Initial landing

Over the course of 23 and 24 August, aircraft from the 25th Air Flotilla carried out preparatory bombing around the airfield at Rabi.[45] The main Japanese invasion force left Rabaul on 24 August, under Matsuyama's command, at 7:00 am. The fleet was made up of two light cruisers, Tenryū and Tatsuta, as well as three destroyers, Urakaze, Tanikaze and Hamakaze, in concert with the transports, Nankai Maru and Kinai Maru, and the submarine chasers CH-22 and CH-24.[50]
At 8:30 am on 24 August, Milne Bay GHQ was alerted by an RAAF
After the initial sighting, the main invasion force, consisting of the heavy naval screening force and the two transports, remained elusive until the morning of 25 August. In an effort to intercept it, US
Meanwhile, earlier in the day, Clowes decided to shorten his lines and passed the order for D Company, 61st Infantry Battalion, which had been sent to Akioma in the east, to withdraw back behind 'B' Company at KB Mission and reposition itself at the No. 3 Airstrip at Gili Gili.[60] A shortage of water craft, however, delayed D Company's departure until the evening of 25/26 August after requisitioning three luggers Bronzewing, Elevala and Dadosee.[59] At around 10:30 pm, the Japanese main force, consisting of over 1,000 men and two Type 95 Ha-Go tanks,[61] had made landfall near Waga Waga, on the northern shore of the bay; due to an error in navigation they came ashore about 3 kilometres (1.9 mi) east of where they had intended, placing them further away from their objective. Nevertheless, they quickly sent out patrols to secure the area, rounding up local villagers, and established a beachhead.[62]
Later that evening, two of the small water craft that D Company were using to withdraw to Gili Gili encountered the Japanese landing force.[59] In the firefight that followed, one of the craft – Elevala – was forced to beach and its occupants forced to return by taking to the jungle on foot, eventually reaching Gili Gili some time later; the other, Bronzewing, was holed and of its passengers, 11 were killed either in the engagement or by the Japanese following their capture.[62]
Japanese advance inland
By dawn of 26 August, advancing west along the coast with armoured support, the Japanese had reached the main position manned by troops from B Company, 61st Infantry Battalion, around KB Mission.[59] The Japanese force moved through the jungle at the edge of the coastal track, and was headed by two light tanks.[63] Although they lacked anti-armour weapons,[64] the Australians were able to turn back the Japanese attack.[59] At this stage, the Japanese suffered a serious setback when their base area was heavily attacked at daylight by RAAF Kittyhawks and a Hudson aircraft, along with B-25s, B-26s and B-17s from the US Fifth Air Force. As a result of the attack, a number of Japanese troops were killed, while a large quantity of supplies was destroyed, as were a number of the landing barges which were beached near the KB Mission.[65] Aside from severely hampering the Japanese supply system, the destruction of the landing barges also prevented their use to outflank the Australian battalions.[66] The Japanese did not have any air cover as the fighters based at Buna which were to patrol over Milne Bay were shot down by Allied fighters shortly after they took off and other aircraft based at Rabaul were forced to turn back due to bad weather.[67]
Nevertheless, the Japanese were still pressing on the 61st Infantry Battalion's positions throughout the day. Field, who had command responsibility for the local area, decided to send two platoons from the 25th Infantry Battalion to provide support. Later, the remaining two rifle companies from the 61st were also dispatched, along with their mortar platoon. The muddy track meant that the Australians were unable to move anti-tank guns into position; however, as a stop-gap measure quantities of sticky bombs and anti-tank mines were moved up to the forward units.[64] At 4:45 pm, with air and artillery support, the Australians launched a minor attack upon the Japanese forward positions which were located about 600 yards (550 m) to the east of the mission, pushing the Japanese back a further 200 yards (180 m). Weary from the day's fighting, though, they withdrew to Motieau, west of the mission.[64][68]

The Australians then attempted to break contact and withdraw towards a creek line where they hoped to establish a defensive line as darkness came. The Japanese stayed in close contact with the Australians, harassing their rear elements.[69] The men from B Company then sought to establish their position, while the 2/10th Infantry Battalion made preparations to move eastwards towards Ahioma, passing through the lines of the 25th and 61st Infantry Battalions.[70] In the early evening, Japanese ships shelled the Australian positions and later, at 10:00 pm, the Japanese launched a heavy attack on the Australians which continued sporadically through the night. By 4:00 am the following morning, the Japanese began to employ infiltration and deception techniques to try to outflank the Australian positions. Anticipating an armoured attack at dawn, the Australians withdrew back to the Gama River,[71] which was situated 1 mile (1.6 km) to the west.[72] During the night, the destroyer Hamakaze entered the bay to make contact with the Japanese troops and land supplies. The landing force had been out of radio contact since 2:00 pm, and the destroyer was unable to raise it with either her radio or visual signalling devices. As a result, Hamakaze departed Milne Bay at 2:30 am without having landed any supplies.[73]
Shortly after dawn, in the air, a Japanese force consisting of eight dive bombers with 12 Zero fighter escorts attacked the Allied airfield at Gili Gili. One of the attacking aircraft was shot down, while only a small amount of damage was inflicted.[74] Meanwhile, around the mission as the Japanese reconnoitred Australian positions, the 2/10th Infantry Battalion, consisting of just 420 men,[75] was ordered to the Gama River by Clowes.[72] This operation was badly planned and did not have a clear purpose; it was launched as both a reconnaissance in force and a counter-attack, but evolved into an attempt to establish a blocking force at KB Mission. Moreover, while the Australians had no knowledge of the strength or intentions of the Japanese, no force would be able to reinforce the battalion once it moved outside the main defensive lines near the airstrips.[76] The 2/10th's forward patrols made contact with the 61st Infantry Battalion at around 10:30 am on 27 August and,[72] upon arrival at around 5:00 pm,[77] they began to establish their position; with only limited entrenching tools, they found the going difficult.[70] At this point, the troops from the 25th and 61st Battalion were ordered to pull back, having lost 18 men killed and a further 18 wounded, along with an unknown number missing in action.[78]
At 8:00 pm the Japanese sent two Type 95 tanks with bright headlights into the plantation.
As the 2/10th withdrew, the 25th Infantry Battalion, which had moved forward from Gili Gili to relieve the 61st, deployed around the airstrip and at Rabi, Duira Creek and Kilarbo, laying mines in key locations.[83] The airstrip proved a perfect defensive location, offering a wide, clear field of fire, while at its end, thick mud served to prevent the movement of Japanese tanks.[84] Around dawn the advancing Japanese troops reached the airstrip and, under the cover of field artillery and mortars, they launched an attack. Although the Australians did not know it, the tanks that were supporting the attack became stuck in the mud and were subsequently abandoned;[85] they would later be discovered by an Australian patrol on 29 August.[86] Meanwhile, troops from the 25th and 61st Infantry Battalions, along with Americans from the 709th Anti-Aircraft Battery, turned back the attacking Japanese infantry.[84] Further strafing by Kittyhawks followed,[87] and the Japanese were forced to fall back 2 kilometres (1.2 mi) to the east of Rabi.[65]
Following this, for the next two days there was a lull in the fighting.

Elsewhere, the 2/12th Infantry Battalion began moving forward from Waigani to enable it to join the fighting later as a counterattacking force.[92] They, along with the 2/9th, were subsequently tasked to carry out an attack from No. 3 Airstrip to KB Mission.[93] Meanwhile, the Japanese also sought to reconfigure their forces and Mikawa decided to reinforce the forces that were already ashore. These reinforcements, consisting of 567 men from the 3rd Kure SNLF and 200 from the 5th Yokosuka SNLF, left Rabaul on 28 August.[94] At around 4:30 pm an RAAF patrol spotted the Japanese convoy – consisting of one cruiser and nine destroyers[86] – and subsequently reported this to the Allied headquarters. Believing that further landings were about to occur, Clowes cancelled his plans to begin a counterattack with the troops from the 18th Brigade.[95][96] Orders were also passed for the 30 Kittyhawks at Gili Gili to be flown off to Port Moresby in case the Japanese succeeded in breaking through to the airfield.[97] The attack did not take place, though, and consequently early in the morning on 29 August they returned, albeit minus two aircraft which had crashed during the move.[98]
The Japanese convoy arrived off Waga Waga at 8:15 pm on 29 August, and began landing troops and supplies. While this was taking place the warships shelled Allied positions around Gili Gili and by 11:30 pm, had completed their landing.[94][99] The shelling was not significant, however, and no casualties resulted from it.[86][95] Throughout 30 August, the Australians carried out patrolling operations while the Japanese laid up in the jungle in preparation for an attack that night.[100]
Later that night the Japanese began forming up along the track at the eastern end of No. 3 Airstrip by the sea,[101] and at 3:00 am on 31 August they launched their attack.[88] Advancing over open ground and illuminated by flares fired by the Australians, the first Japanese attack was repelled by heavy machine gun and mortar fire from 25th and 61st Infantry Battalions as well as the 46th Engineer General Service Regiment,[88] and artillery fire from the Australian 2/5th Field Regiment. A further two banzai charges were attempted only to meet the same fate, with heavy Japanese casualties, including the Japanese commander, Hayashi.[102][103] At this point, Commander Minoru Yano, who had arrived with the Japanese reinforcements on 29 August, took over from Hayashi, and after the survivors of the attack had reformed in the dead ground around Poin Creek, he led them about 200 yards (180 m) north of the airstrip in an attempt to outflank the 61st Infantry Battalion's positions on Stephen's Ridge.[104] After running into a platoon of Australians who engaged them with Bren light machine guns, the Japanese withdrew just before dawn to the sounds of a bugle call.[105] The Japanese troops who survived this attack were shocked by the heavy firepower the Allied forces had been able to deploy, and the assault force was left in a state of disarray.[106]
Australian counterattack
Early on 31 August, the 2/12th Infantry Battalion began moving towards KB Mission, with 'D' Company leading the way and struggling through muddy conditions along the track, which had been turned into a quagmire due to the heavy rain and equally heavy traffic.[107] After passing through the 61st Infantry Battalion's position, at around 9:00 am they began their counterattack along the north coast of Milne Bay.[88] As the Australians went they were harassed by snipers and ambush parties. They also encountered several Japanese soldiers who tried to lure the Australians in close for attack by pretending to be dead.[108] In response, some Australians systematically bayoneted and shot the bodies of Japanese soldiers.[106] At noon, the 9th Infantry Battalion, a Militia unit from the 7th Infantry Brigade, dispatched two companies to occupy some of the ground that the 2/12th had regained around No. 3 Airstrip and the mission.[109]
Making slow going amidst considerable resistance, the Australians nevertheless reached KB Mission late in the day. A force of Japanese remained there, and the Australians attacked with bayonets fixed. In the fighting that followed 60 Japanese were killed or wounded. The Australians were then able to firmly establish themselves at the mission.[110] Meanwhile, the two companies from the 9th Battalion took up positions at Kilarbo and between the Gama River and Homo Creek with orders to establish blocking positions to allow the 2/12th to continue its advance the following morning.[109][111]
That night, a force of around 300 Japanese who had been falling back since they had run into the 61st Infantry Battalion on Stephen's Ridge, encountered positions manned by the 2/12th and 9th Infantry Battalions around the Gama River. In a surprise attack, the Australians inflicted heavy casualties on the Japanese. After the battle the Australians estimated that up to 90 had been killed.[111] Following this the Japanese began to employ infiltration techniques in an attempt to pass through the numerous listening posts that had been set up along the side of the track which formed the front of one side of the 2/12th's position.[112] Elsewhere, at the mission, starting at around 8:00 pm, they carried out harassment operations in an effort to distract the Australians and assist their comrades to try to break through the Australian positions from the Gama River. This lasted throughout the night.[113]
The following morning, 1 September, the 2/12th Infantry Battalion went on the offensive again,[114] while a force of seven Kittyhawks attacked the Japanese headquarters around Waga Waga.[115] By this time, the Japanese had abandoned the objective of reaching the airfields and instead sought only to hold off the Australians long enough to be evacuated.[116] This information was not known by the Allies, however, who were in fact expecting the Japanese to undertake further offensive action. In this regard, the 2/9th, initially with orders to join the 2/12th's counterattack, was delayed an extra day after an erroneous intelligence report from MacArthur's headquarters warning Clowes of a renewed Japanese attack forced him to briefly adopt a more defensive posture.[117] The attack did not occur and, as a result, on 2 September the 2/9th was moved by barge up to the KB Mission. The next day it took over from the 2/12th and led the Australian advance.[118] With the Japanese position at Milne Bay close to collapse, on 2 September Yano sent a radio message to the headquarters of the 8th Fleet which stated: "[w]e have reached the worst possible situation. We will together calmly defend our position to the death. We pray for absolute victory for the empire and for long-lasting fortune in battle for you all".[119]
"Lying across the [air]strip were dozens of dead Japs... As our officer crossed in the vanguard a Jap, apparently wounded, cried out for help. The officer walked over to aid him, and as he did the Jap sprang to life and hurled a grenade which wounded him in the face. From then on the only good Jap was a dead one, and although they tried the same trick again and again throughout the campaign, they were dispatched before they had time to use their grenade.
"Our policy was to watch any apparent dead, shoot at the slightest sign of life and stab with bayonet even the ones who appeared to be rotten. It was all out from then on, neither side showing any quarter and no prisoners were taken."
The terrain in this part of the bay offered significant advantage to defending forces, lined as it was with numerous creeks which slowed movement and obscured firing lanes.[121] Throughout 3 September, the 2/9th Infantry Battalion came up against significant resistance; in one engagement that took place around mid-morning along a stream to the west of Elevada Creek they lost 34 men killed or wounded as they attempted to force their way across a creek.[122] Engaged with sustained machine gun fire, the two assault platoons withdrew back across the creek while elements of another company that was in support moved to the northern flank. Launching their assault, they found that the Japanese had withdrawn, leaving about 20 of their dead.[123]
Following this, the 2/9th advanced a further 500 yards (460 m), reaching Sanderson's Bay, before deciding to set up their night location.[124] That night Japanese ships again shelled Australian positions on the north shore of the bay, but without causing any casualties among the defenders.[125]
On 4 September, the Australian advance continued as the 2/9th moved up the coast either side of the coastal track. After about one hour, the advance company struck a Japanese defensive position at Goroni.
Japanese withdrawal
Following the fighting on 31 August, the Japanese forces ashore had reported the situation to their headquarters at Rabaul. In response, plans were made to send the Aoba Detachment, which comprised the Army's 4th Infantry Regiment and an artillery company,[130][131] to Rabi to complete the capture of the airfield.[103] However, they were not scheduled to arrive until 11 September and so it was planned in the meantime to reinforce Yano's men with 130 men from the 5th Yokosuka SNLF. An abortive attempt was made to land these troops on 2 September and then again on 4 September. By that time, however, as further reports were received by the Japanese headquarters, it became apparent that Yano's troops would not be able to hold out until the Aoba Detachment could arrive. As a result, on 5 September, the Japanese high command ordered a withdrawal. This was carried out from the sea that evening.[132][133]
Meanwhile, six Beauforts of No. 100 Squadron RAAF had arrived at Milne Bay on 5 September. An additional three Beaufighters of No. 30 Squadron RAAF, the first to operate this aircraft, joined them the following day.[115] The Beauforts were tasked with providing additional support against further landings and undertaking anti-shipping missions.[3] On 6 September, the Allied offensive reached the main camp of the Japanese landing force, fighting a number of minor actions against small groups that had been left behind after the evacuation.[134]

Shortly after ten on the evening of 6 September, as the freighter Anshun was continuing unloading cargo under her lights, the port came under fire from the Japanese cruiser Tenryū and the destroyer Arashi with Anshun receiving about ten hits from the cruiser and rolling onto her side.[135] The Japanese ships also shelled shore positions at Gili Gili and Waga Waga and illuminated, but did not fire on, the hospital ship Manunda which was displaying her hospital ship colours and lights.[135][136] The next night, two Japanese warships – a cruiser and a destroyer – bombarded Australian positions causing a number of casualties for 15 minutes before leaving the bay; it would be their final act in the battle.[137] During the mopping up operations that followed, patrols by Australian troops tracked down and killed a number of Japanese troops who were attempting to trek overland to Buna.[3]
The 350 Japanese troops who had been stranded on Goodenough Island after their barges were destroyed on 24 August were not rescued until late October. An attempt to evacuate the force on 11 September ended in failure when the two destroyers assigned to this mission were attacked by USAAF aircraft, resulting in the loss of Yayoi. Two further attempts to rescue the force on 13 and 22 September were unsuccessful, though supplies were air-dropped on Goodenough Island. A submarine landed further supplies and evacuated 50 sick personnel on 3 and 13 October.[138] As part of the preparations for the attack on Buna and Gona, the 2/12th Infantry Battalion was assigned responsibility for securing Goodenough Island on 19 October. The battalion landed on the island three days later. A series of small engagements on 23 and 24 October cost the Australian force 13 killed and 19 wounded, and the Japanese suffered 20 killed and 15 wounded.[139] The remaining Japanese troops were evacuated by two barges to nearby Fergusson Island on the night of 24 October, and the light cruiser Tenryū rescued them two days later.[140] After securing the island, the 2/12th began work on building Vivigani Airfield on its east coast.[141]
Aftermath
Base development

The Allies continued to develop the base area at Milne Bay in support of the counter-offensive along the northern coast of Papua and New Guinea. The American base became US Advanced Sub Base A on 21 April 1943, US Advance Base A on 14 August and US Base A on 15 November.
A bitumen-surfaced second runway was built at No. 1 Airstrip by No. 6 Mobile Works Squadron RAAF, after which the original runway was only used for emergencies and taxiing. The minefield around No. 3 Airstrip was lifted and the airstrip was completed, with revetments and hardstands for 70 medium bombers. A new wharf, known as Liles' wharf after the American engineer who supervised its construction, was built in September and October 1942. This was capable of handling Liberty ships. Henceforth ships could sail direct to Milne Bay from the United States, reducing the pressure on Australian ports and saving two or three days' sailing time in addition to the time formerly taken to unload and then reload the cargo on smaller ships in those ports.[146] PT boats were based at Milne Bay from December 1942, with PT boat overhaul facilities, a destroyer base, a transshipment and staging area and a Station Hospital also constructed.[147][6]
On 14 April 1943, the Allied base was attacked by 188 Japanese aircraft during the Japanese air offensive,

Results
The Australians estimated Japanese casualties to be around 700 to 750 killed in action,[3][130] and a Japanese source reported 625 killed in action.[2] Of the 1,943 Japanese soldiers that were landed at Milne Bay, ships from the Japanese 18th Cruiser Division managed to evacuate 1,318 personnel, including 311 who were wounded.[2] The Australians suffered 373 casualties, of which 167 were killed or missing in action. US forces lost 14 personnel killed and several wounded.[3]
Although Allied casualties during the battle had been light, in the wake of the battle, Milne Bay suffered an epidemic of malaria that posed a threat to the base as great as that from the Japanese attack. Over one-sixth of Milne Force, including Clowes, came down with the disease. The incidence of malaria soared to 33 per thousand per week in September (equivalent to 1,716 per thousand per annum), and to 82 per thousand per week in December (equivalent to 4,294 per thousand per annum). At this rate, the whole force could have been incapacitated in a matter of months. It placed enormous strain on the medical units and the supplies of anti-malarial drugs. The Chief Pathologist of New Guinea Force, Lieutenant Colonel
Strategically, as a result of the fighting around Milne Bay, Japanese operations within the region were constrained. The defeat at Milne Bay kept them from bypassing the holding action that the Australians were conducting on the Kokoda Track.[158] Milne Bay showed the limits of Japanese capability to expand using relatively small forces in the face of increasingly larger Allied troop concentrations and command of the air.[159] The Japanese commanders were then forced to change their plans in the region, shifting their focus towards repelling the US forces that had landed on Guadalcanal,[160] while maintaining a smaller effort around Buna–Gona, under Major General Tomitarō Horii. Once they had retaken Guadalcanal, they planned to reinforce Horii's forces and launch a reinvigorated attack on the Australians around Port Moresby.[160] In the end, subsequent defeats at Buna–Gona and on Guadalcanal did not allow them to implement these plans, as the Allies gained the ascendency in the region throughout late 1942 and the Japanese were forced to fall back to the northern coast of New Guinea.[161][162] In the aftermath of the battle, a large amount of intelligence was also gained by the Allies, providing their planners with a better understanding of the strengths and weaknesses of the Japanese and their equipment. It also demonstrated that the Militia were an effective fighting force.[158]
The most significant result, though, was the effect that the victory had on the morale of Allied servicemen elsewhere in Asia and the Pacific, especially those on the Kokoda Track, and British troops
"We were helped, too, by a very cheering piece of news that now reached us, and of which, as a morale raiser, I made great use. Australian troops had, at Milne Bay in New Guinea, inflicted on the Japanese their first undoubted defeat on land. If the Australians, in conditions very like ours, had done it, so could we. Some of us may forget that of all the Allies it was the Australian soldiers who first broke the spell of the invincibility of the Japanese Army; those of us who were in Burma have cause to remember."
In Australia, initial public reaction to the victory at the time was one of cautious optimism. An article in The Canberra Times from early September 1942 labelled the victory a "tonic surprise", and while highlighting the example as a portent of future battlefield success by Australian forces in the region, also pointed out the task that lay ahead of the Australians in New Guinea remained a "major problem". Most significantly, though, it highlighted the importance of morale in turning the tide in the war, describing it as "the bridge that must carry all the vast and complicated effort being directed towards victory".[166] Another article, which appeared in The West Australian at the same time, while also preparing the Australian public for the tough fighting that would follow in New Guinea, hailed the victory at Milne Bay as a "turning point", the instance of which signalled an end of a "rearguard campaign" and the start of an Allied offensive in the region.[167]
Amongst individual Australian soldiers, the news of the victory helped to dispel some of the notions about the invincibility of the Japanese soldier that had developed in the psyche of Allied soldiers following the defeats of early 1942,[158] and which had impacted on Allied planning up to that point.[168] Some of these notions would remain until the end of the war, but the news of Milne Bay allowed some soldiers to rationalise the Japanese soldiers' past victories as being the result of tangible factors, such as numerical superiority, that could be overcome, rather than innate factors associated with the intangible qualities of the Japanese soldier that were not so easily overcome.[169] After this, amongst the Allies there was "a sense that fortune's wheel was turning",[168] and although leaders such as Blamey emphasised the difficulties that lay ahead, a feeling of confidence in eventual victory emerged.[170] MacArthur warned the War Department that success was attributable to good intelligence that allowed him to concentrate a superior force at Milne Bay, and might not be repeatable.[171]
After the war, the Australian Army commemorated the battle through the awarding of a battle honour titled "Milne Bay" to a number of the units that took part. The units chosen were the 9th, 25th, 61st, 2/9th, 2/10th and 2/12th Infantry Battalions.[172] The two RAAF fighter squadrons that had taken part in the fighting were also singled out for praise by the Australian commanders for their role in the battle. Rowell stated: "the action of 75 and 76 Squadrons RAAF on the first day was probably the decisive factor", a view Clowes endorsed in his own report.[173]
