The Australians faced significant supply issues despite the modest size of their forces, and the 39th Battalion was subsequently withdrawn to ease the logistic burden. The Japanese advance resumed on 26 August, forcing Potts to mount a series of delaying actions as the 21st Brigade successively fell back, first to Eora Creek on 30 August, Templeton's Crossing on 2 September, and Efogi three days later on 5 September. However, the Japanese were now increasingly hampered by supply problems as they became over extended, while the Australian defence also became better organised. Regardless, the effectiveness of the Australian units was increasingly reduced through exhaustion and sickness from operating in the harsh terrain.

On 10 September, Potts handed over command to Porter, who was subsequently forced to withdraw to Ioribaiwa.

This first plane arrived around 15:00, just as the Japanese troops attacked the 75 militiamen and handful of local PIB troops now defending Oivi. Despite repeated frontal and flank attacks over the next six hours the Japanese failed to break through. By 17:00, the remaining reinforcements had not yet arrived and Templeton moved down the track to warn them that they might encounter Japanese troops between them and his position. Unknown to Templeton the Japanese had already surrounded his troops and he was believed to have been killed when he ran into them.Japanese wartime documents translated in 2010 revealed that Templeton had been wounded and captured alive. During interrogation, he "revealed" to the Japanese OIC that 80,000 Australian troops had landed at Port Moresby and would be advancing up the track. In fact, there were less than 1,000 troops available to defend Port Moresby and the documents indicate that Templeton's claim may have been responsible for the unexplained slowing down of the early Japanese advance. Researchers located the Japanese soldier who had buried Templeton who explained that Templeton was killed after he laughed at the OIC who then stabbed him through the stomach with a sword. Now aged in his 90s, the soldier described the place of burial and later personally led researchers to the spot described.

Watson then assumed command. As the track to Kokoda was now cut off, Lance Corporal Sanopa of the PIB led the Australian and Papuan troops, under the cover of darkness, to Deniki by means of a creek below Oivi. At Deniki, the men joined up with Owen and the rest of 'B' Company and on the morning of 27 July, Owen—with the remnants of the Militia company and a handful of troops of the PIB, who had had little food or rest for the previous three days and knowing he would be facing some 500 Japanese marines—decided to attempt a defence of the Kokoda airstrip and hope that reinforcements would arrive in time to support him. Leaving around 40 troops at Deniki, he took the remaining 77 and was deployed in Kokoda by midday on 28 July. Owen then contacted Port Moresby by radio to request reinforcements. Shortly afterward, two Douglas transports arrived overhead, carrying reinforcements from the 39th Battalion; however, after circling the airfield, they eventually returned to Port Moresby without landing.There is a discrepancy amongst the sources about the reasons behind why the American pilots did not land. Keogh states that they were ordered to return to base by Morris, who was unable to determine whether the Australians still held Kokoda, see Keogh 1965, p. 176. Brune, however, states that the pilots were not ordered to return to Port Moresby, but in fact refused to land due to fears that the Japanese would attack before they could take off again. According to eyewitnesses on one of the planes, the pilot repeatedly refused Lieutenant Lovell's demand that they land and that they could clearly see Australians clearing barricades from the airfield, indicating that the 39th Battalion still held the airfield, see Brune 2003, pp. 102–103.

At 02:00 on 29 July, the Japanese launched an attack on the airfield, pouring down intense machine gun and mortar fire on the Australian position before launching an assault. Close quarters hand to hand fighting ensued, and after Owen received a fatal wound, Watson took command. Only after his position was completely overrun did he give the order to his troops to withdraw to Deniki. The Kokoda airstrip was captured by the Japanese who—having achieved their objective and having suffered considerable losses—did not pursue the Australians.

Although the defenders were poorly trained, outnumbered and under-resourced, the resistance was such that, according to captured documents, the Japanese believed they had defeated a force more than 1,200 strong when, in fact, they were facing only 77 Australian troops. Next to establishing the strength of the defending forces, and with the strategically vital supply base and airstrip at Kokoda within his grasp, Tsukamoto deemed the track to be practicable for a full-scale overland assault against Port Moresby.

 and spotters in the hills until an American radar unit arrived in September with better equipment. Japanese bombers were often escorted by fighters which came in at 30000 ft (9,144 m)—too high to be intercepted by the P-39s and P-40s—giving the Japanese an altitude advantage in air combat. The cost to the Allied fighters was high. By June, 20–25 P-39s had been lost in air combat, while three more had been destroyed on the ground and eight had been destroyed in landings by accident. The Australian and American anti-aircraft gunners of the Composite Anti-Aircraft Defences played a crucial part. The gunners got a lot of practice; Port Moresby suffered its 78th raid on 17 August 1942. A gradual improvement in their numbers and skill forced the Japanese bombers up to higher altitude, where they were less accurate, and then, in August, to raiding by night.

Battles along the Track

Second Battle of Kokoda

On the arrival of the 39th Battalion, Cameron decided to retake Kokoda, a three-hour march from Deniki. This risky attack against unknown enemy forces later found to number 1,000 was carried out using three companies of the 39th Battalion attacking along different tracks. Between 06:30 and 08:00 on 8 August, the three companies left Deniki separately. Only Captain Noel Symington's 'A' Company succeeded in reaching Kokoda and successfully re-took the village, finding it very lightly defended. 'D' Company ran into enemy troops which resulted in heavy fighting continuing throughout the day with the Japanese continually reinforcing their position. As nightfall approached 'D' Company began a fighting withdrawal which lasted two days. 'C' Company was ambushed by a large Japanese force and pinned down. After their commanding officer was killed, the company repeatedly attempted to withdraw under heavy fire during the day but were unable to do so until night fell. Upon reaching Deniki, their pursuers continued the attack on Cameron and his troops for several hours before withdrawing towards Kokoda. At 10:00 on the following day, two Papuan policemen arrived at Deniki to advise Cameron that they had occupied Kokoda the previous day and he was awaiting reinforcements and supplies. Cameron contacted Port Moresby and was told that the reinforcements would not be available until the following day due to poor weather conditions.

Having repulsed 'C' and 'D' Companies, Lieutenant Colonel Tsukamoto now concentrated his troops against 'A' Company. From late morning on 9 August, the Japanese repeatedly attacked Captain Symington's force at Kokoda and the battles continued into the night when the Japanese were able to infiltrate the Australian perimeter under cover of darkness. Hand to hand fighting continued until the next morning. An attempt to reinforce 'A' Company using troops from the 49th Battalion failed when the aircrew were unable to establish that the airstrip was in friendly hands. By late afternoon, the Australians had consumed all of their food and had very little ammunition left. As such, at around 19:00, Symington ordered a fighting withdrawal to the west of the Kokoda plateau and then at first light made for Deniki. Unable to break through the Japanese lines while carrying their wounded they entered the village of Naro, sending a villager to Deniki for help where Warrant Officer Wilkinson volunteered to lead a small patrol of native troops to Naro. Wilkinson reached Naro and led the men of 'A' Company past the Japanese to Isurava, rejoining the rest of the 39th Battalion on 13 August.

Battle of Isurava

, who had assumed command on 16 August—and elements of the 49th and 53rd Battalions, some 400-strong. The Japanese force made contact with the outer positions of Maroubra Force and began frontal attacks against the dug-in defenders with the aid of a mountain gun and mortars manhandled up the Track. Japanese reconnaissance had revealed a parallel track bypassing Isurava, defended by the Australian 53rd Battalion. The 2/14th Battalion had been dispatched from Myola the previous day with orders to relieve the 39th, and a company reached their position at Isurava in the middle of the afternoon on 26 August, while others deployed to Alola and Templeton's Crossing. Nevertheless, the 39th were forced to stay on as several times the Japanese threatened to break through the perimeter. Potts, who had taken command of Maroubra Force, realising that Horii had launched a major attack, decided to deploy the 2/14th at Isurava, using the 39th to screen their movement, while bringing up the 2/16th to Myola where it would be held in reserve. By the time the 2/14th Battalion had deployed, the Japanese were still able to field a force some 5,000 strong.
Japanese tactics were little-changed from the campaign through Malaya—pin the enemy in place with frontal attacks while feeling for the flanks, with a view to cutting off enemy forces from the rear. However, Horii was on a strict timetable; any delays in finding the Australian flank meant the gradual debilitation of his force from disease and starvation. As a result, Maroubra Force endured four days of violent attacks from aggressive, well-trained and well led Japanese troops.

As dawn broke on 27 August, the Australians defending Isurava were subjected to heavy mortar and mountain gun fire as the Japanese launched a number of probes against the 39th Battalion's lines. As the morning progressed, the probes began to penetrate the 39th's defences; however, the deployment of the 2/14th Battalion restored the situation and by nightfall the Australian perimeter had been re-established. The situation on the right flank, where the 53rd Battalion was guarding the alternate track, was critical, however. A Japanese force was sent to open this route, and met with success. Infiltrating the 53rd's perimeter, the Japanese managed to achieve a break-in and rolled up the Australians' positions, killing a number of the battalion's senior officers, including its commanding officer, Lieutenant Colonel Kenneth Ward. As a result of this loss, communications between the companies broke down rendering co-ordinated action impossible and 53rd gave ground, retreating to the Track junction behind Isurava. Although the Japanese failed to exploit the situation, the way to Alola was open to them and as a result Potts was forced to bring up the 2/16th Battalion to plug the gap.

On 28 August, the fighting continued along the front of the Australian position and on both flanks. The Japanese commander—realising that the Australians had brought up reinforcements—decided to commit the two battalions he had been holding back in reserve. The following day, the Japanese attacked with the equivalent of six battalions; in possession of the ridges that dominated the Australian position from both sides of the valley in which it sat, the Japanese were able to lay down considerable volumes of mortar and machine gun fire in support of their assaults. Unable to respond with similar firepower, the Australian perimeter began to shrink, and it was during this stage of the fighting that Private Bruce Kingsbury of the 2/14th made a unique individual contribution to the campaign and was posthumously awarded the Victoria Cross

Eyewitnesses said that Kingsbury's actions had a profound effect on the Japanese, halting their momentum. However, as Australian casualties mounted and ammunition ran low, the Japanese came close to making a breakthrough on the alternate track. Horii had now deployed several companies on the flanks and near the rear of the 2/14th and 39th Battalions, threatening the Australian positions with encirclement. Outnumbered, Maroubra Force withdrew towards Nauro and Menari. Potts relieved the exhausted 39th and 53rd Battalions; they were ordered to make their way back to Port Moresby. The 53rd—whose performance during the fighting had come to be seen in less than favourable light—was reduced to being used for reinforcements and work parties, however, the 39th subsequently returned to the battle when the forward troops were under pressure.

. Many officers saw this as a medical rather than a disciplinary issue, and did not compel their men to take their medicine. Moreover, anti-malarial supplies of all kinds were in short supply.

Isurava to Brigade Hill

No suitable defensive terrain existed between Isurava and a feature known as Mission Ridge, which was south of Nauro and Myola. As a result, Brigadier Potts and Maroubra Force retreated back through Menari, mounting small delaying actions where possible, reaching Eora Creek on 30 August, Templeton's Crossing on 2 September and then Efogi on 5 September.
Retreating soldiers, Papuan porters and wounded immediately flooded the Track, causing it to become a sea of mud in parts. However, no wounded were left behind—Japanese patrols routinely mutilated and executed any wounded found; sometimes using the corpses as bait to draw Australian soldiers into ambushes—overall 750 wounded were carried to safety. Colonel Kingsley Norris in the 7th Division Medical Services report noted that the difficulty of providing stretchers which each required eight bearers meant those wounded who were able to stagger were treated with "absolute ruthlessness" and not provided with stretchers. In one case, a casualty with a fractured patella with a 2 in (50.8 mm) gap between the two halves walked for six days and some with worse injuries volunteered to walk to free a stretcher for the more seriously wounded. Notable was the bravery of the Australian field doctors; among them Captain Dr. Allan Edward McGuinness, of the 2/2nd Battalion, was awarded the Military Cross

 in December 1943 for "[c]ourage and unselfish devotion at Saputa and Eora Creek". It was at Saputa on 27 November 1943 that seven Japanese "Zeros" bombed a clearly marked Australian field hospital, killing 25 men, including two doctors.

The withdrawal back to Efogi presented more problems for the Australians. To the east, at Myola, a large dry lake bed was being used as a supply dump. Potts' decision to fall back meant that there was every chance that this important drop zone might be lost. The supply situation had become critical, indeed because food and supplies had been slow to arrive, the 2/14th and 2/16th Battalions had been forced to wait several days until enough supplies arrived for them to carry out their orders, time which allowed the Japanese to concentrate their forces. Nevertheless, Allied air drop techniques and assets had been steadily improving throughout the campaign and Allen, under significant pressure from Blamey and MacArthur, asked Potts when offensive actions would be resumed now that air-drops were ensuring a regular, albeit sparse, flow of supplies. Potts in turn requested the 2/27th Battalion as reinforcements. In view of the situation at Milne Bay, MacArthur withheld this force until the situation at Milne Bay was clearer. Allen then ordered Potts to hold Myola as a forward supply base and to gather sufficient supplies for an offensive against the Japanese advance. But Potts was in an indefensible position; threatened with an outflanking manoeuvre through a loop of the Track and with insufficient terrain near Myola suitable for a set-piece defence, he retreated through Myola, destroying the supply base behind him.

Battle of Brigade Hill

Maroubra Force withdrew to the next defensible strong point on the Track, a feature known as Mission Ridge. Following the containment of the Japanese at Milne Bay, Allen finally released the 2/27th Battalion from the divisional reserve at Port Moresby. After advancing along the Track from Port Moresby, the 2/27th finally joined Maroubra Force at Kagi on 4 September where they took over a quantity of automatic weapons from the 39th Battalion which was being withdrawn. Moving onto Mission Ridge, the 2/27th was joined on 6 September by the 2/14th and the 2/16th Battalions, thus allowing Brigadier Potts to finally commit his entire brigade to the battle. Taking up positions on a hilltop straddling the Track, which later became known as "Brigade Hill", Maroubra Force awaited the Japanese advance. Unknown to the Allies, the Japanese managed to land reinforcements on the northern coast and on 8 September, a force of around 1,000 Japanese launched an attack on the Australian positions at Mission Ridge. The attack began with frontal attacks, which fell upon the Australian leading elements, although these were beaten off with stubborn defence. The Japanese then launched a strong flank attack, with a force of around 5,000 men, aimed at cutting off the lead elements from the rest of Maroubra Force. The flank attack cut the Australian force in two, separating the brigade headquarters staff from the three battalions. With his headquarters about to be overrun, Brigadier Potts and the rear elements of Maroubra Force were forced to retreat back along the Track to the village of Menari.
Now surrounded, the 2/14th and 2/16th charged the Japanese lines but failed to break through. Having run out of rations and with almost no ammunition left, when it became clear that they were in danger of being cut-off and destroyed, the remaining soldiers of all three Australian battalions left the Track and were ordered to "go bush", effectively an order of every man for himself, and find their own way to the village of Menari. The Japanese pursued them but a rearguard action by 'B' and 'D' Companies of the 2/27th caused them to break contact."That was a tremendous operation, a wonderful action by B Company. They had to buy time...and the way they did it they counter-attacked against the Japs. The Japs were so shocked they broke contact...They had the impetus and they were hot on our heels. We were withdrawing with our wounded...And the 'B' Company was given this job to stop them. Instead of just standing there and firing at them they counter-attacked and that must have shocked them considerably." — Captain Harry Katekar, adjutant 2/27th Battalion, see Brune 2003, pp. 208–209. The 2/14th and 2/16th Battalions managed to re-unite with Brigadier Potts and 21st Brigade headquarters at Menari, but the 2/27th Battalion was unable to reach Menari before the rest of the brigade was again forced to retreat by the advancing Japanese. The 2/27th—along with wounded from the other battalions—were forced to follow paths parallel to the main Track, eventually rejoined the main Australian force at Jawarere, then making their way back to Ioribaiwa, and thence to Imita Ridge. Elements of the 2/14th and 2/16th Battalions accompanying Potts later managed to regroup as a composite battalion for the defence of Imita Ridge, but the 2/27th, feared lost, only managed to rejoin a fortnight later, after the Japanese retreat began, having made a difficult trek over the mountains to Jawarere 15 mi (24.1 km) east of Ilolo.

The defeat of the 21st Brigade at Brigade Hill finally ended Maroubra Force's defence of the Kokoda Track as a cohesive fighting unit, and was a decisive victory for the Japanese. The defeat was one of many factors leading later to the infamous "running rabbits" incident at base camp at Koitaki. On 8 September, Rowell informed Blamey that he had decided to relieve Potts.

, they took up positions at Ioribaiwa. Shortly afterward, however, as the Japanese launched their attack, Eather made the decision to withdraw to what he felt was a more defensible position at Imita Ridge, 40 km (24.9 mi) from Port Moresby. As the 25th Brigade, along with the 3rd and 2/1st Pioneer Battalions dug-in, the remnants of the 21st Brigade moved back and by 20 September the Australians had established a strong position on the ridge.

All reinforcements were being diverted to Guadalcanal and his long supply line had broken down. The meagre supplies captured from the Australians were insufficient for a new offensive. The foodstuffs taken from the former Australian supply dump at Myola had been contaminated by the Australians, and Horii believed that his troops were so hungry and physically weak that they would barely be able to defend the positions they held already, let alone continue the advance.

 Harukichi Hyakutake decided that he only had sufficient troops and materiel to defeat the Allied forces on Guadalcanal. Hyakutake prepared to send more troops to Guadalcanal in another attempt to recapture Henderson Field. With the concurrence of the Japanese command staff, he ordered General Horii to withdraw troops on New Guinea, who were within 48 km (29.8 mi) of Port Moresby, to the Buna–Gona beachheads until the issue at Guadalcanal was decided.

Flanking manoeuvre fails

While Rowell felt he could contain the Japanese with the extra troops, MacArthur was anxious to flank the Japanese. He asked his staff to plan a flanking manoeuvre that would push the Japanese off the mountains more quickly. Since the 32nd Division in Australia had to move to another camp in any event, MacArthur issued orders for them to move to New Guinea. Brigadier General Hanford MacNider

—in charge of the G-4 (Logistics) unit in MacArthur's headquarters group—learned when he arrived in Port Moresby that the previously chosen flanking route across the peninsula to Wairopi proposed by headquarters staff was not practical. It crossed the Australians' rear area and a region where the soldiers could be cut off by the Japanese. It was also so mountainous that the only way they could receive supplies would be by air. An alternative route was then considered: an 85 mi (136.8 km) trail, from Port Moresby along the coast to Kapa Kapa, thence inland via Kalikodobu, Arapara, Laruni, to Jaure. From Jaure other minor trails would lead the soldiers to Wairopi and Buna. The total distance over the mountains to the Japanese positions was over 130 miles (209 km), and most of the trail was barely a goat path.

Beginning on 14 October, 1,250 men from the 32nd Division—members of the 2nd Battalion, 126th Infantry Regiment, 114th Engineer Battalion, and 19th Portable Hospital, commanded by Lieutenant Colonel Henry A. Geerds—left Karekodobu on foot. The men departed Karekodobu—nicknamed "Kalamazoo" by the GIs who had a hard time pronouncing the local name—were accompanied by several hundred natives.

They began to depart from Jaure on 28 October and reached the Natunga area on 2 November. They spent more than a week drawing rations, helmets, boots, and other equipment before pushing on to Gora and Bofu, which they reached on 12 November. On 20 November 1942, after 42 days of crossing extraordinarily difficult terrain, including hogback, razor-sharp ridges, dense jungle, and mountainous high-altitude passes, and without having encountered a single enemy, 'E' Company was the first unit to reach Soputa at the front.

Tropical diseases and exhaustion had taken a severe toll on the 2/126th, which had lost a significant part of its strength before it first engaged the Japanese in the subsequent Battle of Buna–Gona.

 and Lockheed 14. Many of the pilots were civilians and losses were high. Four of the 32 available transports were lost in August 1942. Myola has been described as "one of the great mysteries of the Papuan campaign". Potts had been told that 40,000 rations had been stored at Myola prior to 17 August and that there was no need for his troops to carry rations and on hearing this he ordered his men to pack five days' rations. Upon arrival, however, Potts found only 5,000 rations. Rowell maintained that the missing rations "fell outside the target area" and in his autobiography he stated that the claim that "the rations were never dropped at all or that the explanation lay in faulty work by an inexperienced staff" was "preposterous", noting that "all through the New Guinea Campaign cargo dropping remained notoriously unreliable". On 21 August, a patrol discovered a second, much larger, dry lake bed at Myola. The two lake beds came to be called Myola 1 and 2 but at this time maps showed and air crew expected only one. It seems likely that drops were made at the wrong one.

Rowell pressed Blamey to ask for additional drops but lacking aircraft MacArthur told Blamey "air supply must necessarily be considered an emergency rather than a normal means of supply" and that he was to find other ways to meet his needs—meaning native carriers. As such, Potts would have to make do with the scheduled drops. Due to a shortage of parachutes, all the supplies had to be "free-dropped"—dropped without parachutes. Packaging at this time was primitive and inadequate, even for normal handling under New Guinea conditions, and woefully inadequate for being dropped from a plane, so the rate of breakages was high. Tactics for dropping had not been developed and the recovery rate was correspondingly small.Logistics was a major problem during the Kokoda campaign. Free dropping consisted of a plane flying as low and slow as possible to the ground at heights of often less than 20 feet (6.1 m) to reduce breakages. Firearms, ammunition and food were wrapped in blankets before dropping. Only two transport aircraft were available at any one time for the track itself. Native bearers were also used to transport food, with each able to carry enough food for one man for 13 days, a bearer would consume most of this load in transit leaving an average of five days rations per bearer reaching the troops and the bearer then required to live off the land for his return.

Australian counter-offensive

In early October, as it became clear that the Japanese were withdrawing north towards coast, the Australians began operations to pursue them. With two Australian brigades committed to this—the 25th and the newly arrived 16th, which had been detached from the 6th Division—the 7th Division's commander—"Tubby" Allen—took operational command on the Kokoda Track. Among the Allied high command, however, there was a concern about the lack of forward momentum and so on 20 October Allen ordered the 16th Brigade—made up of the 2/1st, 2/2nd and 2/3rd Battalions, with the Militia 3rd Battalion in reserve—under the command of Brigadier John Lloyd to take over responsibility for the forward area from the 25th Brigade in an attempt to reinvigorate the advance. The 25th, however, remained in the area and throughout October each brigade in turn kept contact with the withdrawing Japanese who fought delaying actions as determined as those of the Australians. The Japanese established a number of heavily defended positions, notably at Templeton's Crossing and Eora Creek which slowed the Australians' advance and resulted in heavy casualties. Unsatisfied with the speed of his advance, Lieutenant General Edmund Herring relieved Allen of command on 28 October, and replaced him with Major General George Vasey, previously of the 6th Division. On 2 November, Kokoda was re-taken without opposition by a patrol from the 25th Brigade. By 13 November, the 16th and 25th Brigades had crossed the Kumusi River at Wairopi, after which they were able to link up with American forces on 16 November.

Strengths and casualties

A total of 13,500 Japanese were ultimately landed in Papua for the fighting during the campaign. Of these, about 6,000 or two regiments, were directly involved in the "forward areas" along the Track. Against this, the Allies assembled approximately 30,000 troops in Port Moresby, although at any one time no more than one infantry brigade, or approximately 3,500 troops, were involved in the fighting for most of the campaign.

Casualties amongst the Australians between 22 July and 16 November 1942 were 39 officers and 586 men killed and a further 64 officers and 991 men wounded, for a total of 625 killed and 1,055 wounded. Non-battle, or sickness, casualties are not accurately recorded but are stated to have been about two to three times the battle casualty figure. The exact number of Japanese casualties is not known. It is believed that of the 6,000 troops, or five infantry battalions, that were committed to the fighting, that up to 75% became casualties, being either killed, wounded or becoming ill. Of the 13,500 that began the campaign, following the withdrawal only about 5,000 reached Buna in late November 1942.

Japanese war crimes

As the Japanese withdrew, it was found that many of the enemy had died of malnutrition with evidence that some Japanese had been reduced to eating wood, grass, roots and other inedible material. Australian soldiers were also confronted with evidence of cannibalism. Dead and wounded Australian and Japanese soldiers who had been left behind in the Australian retreat from Templeton's Crossing were stripped of flesh. In 1987, a Japanese documentary Yuki Yuki te Shengun contained interviews with Japanese soldiers who confessed to cannibalism on New Guinea. Soldiers testified that the Japanese had not run short of rations having uncovered rice dumps and significant amounts of tinned food. During the Tokyo War Crimes trial that was held after the war, however, there was not enough evidence to bring formal charges with regards to the claims of cannibalism; nevertheless, some Japanese soldiers were tried and convicted in Australian-run military courts held in New Guinea.

The Japanese were also responsible for the execution of two female missionaries, May Hayman and Mavis Parkinson, during the campaign. Shortly after the Japanese landing at Buna on 21 July 1942, the two women fled the mission with a priest. During their escape, they were aided by locals and a small group of Australian soldiers for a number of months; however, after the other members of their party were killed in an ambush in August they were handed in to the Japanese. Upon capture they were interrogated for information by members of the Kempeitai

After the strategic debate between the Imperial Japanese Army and Imperial Japanese Navy had been settled in late February with a decision to isolate rather than invade Australia, the Army continued to maintain its view that invading Australia was impractical, but agreed to extend Japan's strategic perimeter and cut Australia off from the US by invading Fiji, Samoa and New Caledonia in the so-called Operation FS

The FS Operation was not implemented, however, due to Japan's defeats in the Battle of the Coral Sea and Battle of Midway and was cancelled on 11 July 1942.
