Why Australians Let Japanese Troops Get Dangerously Close Before Opening Fire

In July 1942, deep in the vertical nightmare of the New Guinea jungle, Australian soldiers did the unthinkable. They watched elite Japanese troops advanced to within 10 m, close enough to see the color of their eyes, and refused to pull the trigger. Conventional military wisdom said this was suicide.

 But for these desperate men, it was the only way to survive a campaign that everyone else had already written off as a lost cause. How did letting the enemy get dangerously close become the secret weapon that saved Australia from a total Japanese invasion? The jungle was trying to kill them before the Japanese even arrived. The rain fell so hard that men could not hear each other shout from 3 ft away.

The mud swallowed boots whole and held them like concrete. The air was so wet and thick that breathing felt like drinking. And somewhere out there, hidden behind walls of green so dense that sunlight never touched the ground, 13,500 Japanese soldiers were coming. By July 1942, Japan had already swallowed the Pacific whole.

 In just 6 months, they had taken 1 and a half million square miles of territory. They had bombed Darwin in northern Australia, killing 235 people and destroying the harbor. Japanese [ __ ] submarines had slipped into Sydney Harbor itself. And in February 1942, Singapore, the giant British fortress that was supposed to be impossible to capture, had fallen in one of the most shocking surrenders in military history, handing 80,000 Allied prisoners to Japanese forces in a single day.

 Now, Japan wanted Port Moresby, the main Allied base on the southern coast of Papua New Guinea. Take Port Moresby, and Japan would have an air base close enough to bomb northern Australia into rubble. Close enough to prepare for an invasion of the Australian mainland. The plan was to send those 13,500 elite soldiers across the Owen Stanley Mountain Range on a track through the jungle called the Cakakota Track, 96 km of the most brutal terrain on Earth.

 And standing between that Japanese force and Port Moresby were Australian soldiers who were about to discover that everything they had been taught about fighting a war was completely wrong. The old way of fighting said this. Spot your enemy, establish a firing line, and shoot at them from at least 300 yards away. Controlled, measured, organized.

It was a way of fighting that had been written for flat European fields where you could see for miles, where the ground was firm, where the enemy walked toward you in the open and you could watch them coming from a safe distance. The Cucakota track was not a European field.

 The ridges rose and fell 2,000 ft within a single kilometer. The jungle canopy above was so thick that pilots flying overhead could not see the ground at all. Visibility through the undergrowth was often less than 20 ft. 20 ft. That is shorter than many living rooms. Imagine trying to fight a war where you cannot see further than your own living room walls.

 And in that tiny window of vision, Japanese soldiers, highly trained, deeply experienced, moving through jungle terrain they had studied for months, would appear without warning, already close, already flanking, already behind you. The Australian units trying to hold fixed defensive lines the old way were being destroyed.

 Carefully built positions were bypassed again and again. Japanese soldiers moved through terrain that Australian commanders had marked on their maps as impossible, appearing from directions that made no sense, cutting off units from behind, surrounding positions that should have been safe. Men were dying having never fired a single shot at an enemy they could actually see.

 The conventional wisdom, hold the line, fire at distance, follow the doctrine, was failing in the worst possible way. It was failing in blood. The man who first saw this clearly was not a general. He was not a graduate of a famous military school. He had not written any papers on how wars should be fought.

 Brigadier Arnold Pototts was 42 years old, a farmer from Western Australia who had first fought at Gallipoli as a young man and then again in the Middle East. He was a citizen soldier, the kind of officer that the professional military tolerated, but never fully respected. The men he commanded were considered even lower on that scale.

 They were called chocoo, short for chocolate soldiers, with the mean suggestion that they would melt the moment things got hard. They were militia soldiers, part-time fighters legally restricted from serving outside Australian territory, which technically included Papua New Guinea, but which the regular army still looked down on with barely hidden contempt.

 The established experts above pots were not interested in what a farmer turned brigadier thought about infantry tactics. General Douglas MacArthur, the Supreme Allied Commander, was running the war from Brisbane, more than a thousand miles away, looking at maps and issuing orders about holding ground and maintaining positions.

 When early battles on the Cakakota track went badly, MacArthur’s explanation was simple and brutal. The Australians were cowards. They were retreating because they lacked the courage to stand and fight. The staff officers with their clean uniforms and their theories agreed. Hold the line. Follow the doctrine. Stop retreating. Pots looked at his dead.

 He looked at the jungle. He looked at the pattern of how Australian positions were being found and destroyed. and he saw something that nobody with a clean uniform and a map could see from a thousand mi away. The Japanese soldier’s greatest advantage was not his rifle or his numbers. It was the jungle itself. It hid him. It moved him.

 It delivered him to within killing distance before anyone knew he was there. And the only way to take that advantage away from him was to use the same jungle in reverse. to hide, to wait, to let the enemy come so close that the jungle that had protected him now trapped him instead. And proving it began with a single sentence that every man in Pots’s command had to absorb and hold on to when every nerve in his body was telling him to do the opposite.

 Wait until the enemy is 5 to 10 m away before you open fire. 5 to 10 m. To understand how close that is, stand in your kitchen and look at the far wall. That is roughly 10 m. Now imagine an armed soldier walking toward you and you cannot fire until he is close enough that you could whisper and he would hear you.

 Every instinct in your body would be screaming. Every muscle would be shaking. And yet this was exactly what Pototts and his company commanders began working toward in the terrible green darkness of the Owen Stanley Rangers in late July and early August of 1942. The logic behind it was brutal and clean.

 In jungle this thick, a defender who opened fire at maximum visible range, which was already only 20 ft in most places, achieved almost nothing useful. The bullets hit leaves and branches and vines and disappeared. The enemy immediately dropped to the ground and was invisible again within seconds. But worse than that, the defender had just told the entire Japanese force exactly where he was.

 Every gun, every eye, every flanking patrol now had a target. The position that had taken hours to build and camouflage was now marked as clearly as if someone had lit a bonfire on top of it. And the Japanese, who were extraordinarily good at using jungle terrain to move around fixed positions, would begin their flanking move within minutes.

 But at 5 to 10 m, everything changed. At that distance in that jungle, a bullet fired from a rifle had almost no chance of missing a human body. There was no time for the enemy to drop and disappear because the gap between the moment of first contact and the moment of being shot collapsed from several seconds to almost nothing.

 The lead Japanese soldiers, the men walking at the very front of the column, were dead before they could communicate anything useful back to the soldiers behind them. And those soldiers behind them were still packed into the narrow jungle trail, unable to see what had happened, unable to spread out because the vegetation on either side was impenetrable, unable to return accurate fire because they had no idea where the shots had come from.

 The jungle that had been the Japanese soldier’s greatest weapon had just become his cage. Pototts and his officers spent hours walking their men through position selection with an obsessive attention to detail that would have seemed excessive anywhere else on Earth and was absolutely necessary here. Every position had to be chosen based on the specific shape of the ground.

 The track had to curve or dip in a way that funneled approaching soldiers into a predictable path. Fields of fire were not measured in hundreds of yards anymore. They were measured in steps. Each man was given a specific zone, a defined slice of jungle in front of his position. And he was told with complete clarity that he would not fire until an enemy soldier entered that zone.

 Not when he could see the enemy. Not when the man next to him fired, only when the enemy crossed into his specific zone. The clearing of firing lanes was done with extraordinary care. Dead branches and low hanging vines that might deflect a bullet were cut at ground level, invisibly in ways that would not alert an approaching enemy to the position’s existence.

 Looking at an Australian position from 20 m away, an approaching soldier would see only jungle. Looking out from within the position, the defenders had clean, short, precise channels of clear air through which a bullet would travel without interference. The geometry was deliberate and deadly. Early results began coming back from small unit actions in August 1942, and the numbers were startling.

 Before the closed fire approach, engagements in the jungle had been producing casualty ratios of three Australian soldiers lost for every one Japanese soldier lost. That ratio in units that were implementing the new approach was moving toward 1:1. In some engagements, it was better than that. Against Japanese troops who were by every measure elite, experienced, wells supplied, and numerically superior, this represented something that had not happened anywhere else in the Pacific War to that point.

 But the men implementing this approach were fighting two battles at once. The second battle was with their own command structure and it was nearly as dangerous as the first. MacArthur’s headquarters in Brisbane looked at a map every morning. On that map, the Cakakota track was a thin line connecting the northern and southern coasts of Papa New Guinea.

 And every morning through August 1942, the mark showing the front line of the fighting was moving south toward Port Moresby, toward the coast, toward disaster. From Brisbane, this looked like one thing only, retreat. MacArthur had already declared that Australian soldiers were showing cowardice. His staff officers were sending increasingly furious messages demanding that ground be held, that positions be maintained, that the retreat stop immediately.

 What those messages could not see, because maps cannot show you mud or rain or the sound of a jungle firefight arriving from seemingly every direction at once, was that Pototts was not retreating in panic. He was retreating by design. Each position was held until the Japanese pressed hard enough that holding it further would mean losing the men in it.

Then the Australians moved back to the next ridge, the next bend in the track, the next piece of terrain that funneled the enemy into the same killing geometry again. Every withdrawal cost the Japanese more men. Every kilometer of ground they gained, they paid for in blood that their supply lines could not replace.

 The man who finally looked at the actual casualty figures rather than just the maps was Lieutenant General Thomas Blay, commanding all Allied land forces. Blay was not a beloved figure. He was hard, political, and often brutally unfair to the men under him. But he had fought in the First World War. He understood at a level that MacArthur did not, that the map and the ground were two entirely different things.

When Blamey reviewed the exchange figures, Japanese dead against Australian dead, and cross-referenced them with captured Japanese supply documents, showing that the South Seas force was already running desperately short of food and ammunition after just weeks of fighting. He understood something critical.

 The Japanese advance was not a victory march. It was a slow bleeding out. And the men doing the bleeding were not cowards retreating from a fight. They were surgeons cutting precisely in the dark with the only tools the jungle allowed. Pots would never receive formal credit for this. The politics above him were already sharpening a knife that had his name on it.

 But below him, in the mud and the rain and the 20-foot walls of green, his company commanders and his platoon leaders and his exhausted, starving Choco soldiers were doing something that would outlast every general who ever dismissed them. They were proving one 5 m engagement at a time that the right idea in the right hands in the right jungle is worth more than all the doctrine ever written in a warm room far from the war.

 And then on September 16th, 1942, the proof arrived in the most definitive form possible. The Japanese advance stopped. There was no single dramatic battle that ended it. No massive counterattack, no brilliant flanking move ordered from a headquarters building in Brisbane. The 13,500 elite soldiers of the Japanese South Seas force who had left their starting point at Buuna in late July with enough supplies for 17 days of fighting had now been in the jungle for nearly 7 weeks.

They had reached a ridge called Iori Baywa and from that ridge on clear nights their soldiers could see the lights of Port Moresby glowing on the horizon. They were 48 km from their objective. They were close enough to almost touch it and they could not take another step. The numbers tell the story with a cold and brutal clarity.

 The South Seas force had started with 13,500 combat troops. By the time the advance stopped at Aayorwa Ridge in midepptember, effective fighting strength had fallen to somewhere between 5,000 and 6,000 men. Approximately 2,500 Japanese soldiers had been killed in action on the Cakakota track. Several thousand more were wounded, sick, or so weakened by starvation that they could no longer hold a rifle steady.

 A force that had consumed Singapore in days and swept across the Pacific in months had been ground down to less than half its strength on a 96 km mud track by soldiers that MacArthur had called cowards. The Australians had lost approximately 1,700 men killed and wounded on the track. The number is not small.

 Every one of those men was someone’s son, someone’s father, someone’s friend. but measured against what they had faced. A numerically superior elite force attacking through terrain of their own choosing with supply lines and momentum and the entire weight of Japanese military power behind them.

 The exchange represented something that military analysts would study for decades. The close fire approach had not just slowed the Japanese advance, it had broken it. Walk the COD track today and the jungle still tells you what happened there. The ridges still rise and fall with the same savage steepness. The canopy still swallows the sky.

 The mud still pulls at your boots with every step. But in late 1942, as Australian forces began pushing back up the track toward Kakakota, what they found in the abandoned Japanese positions said everything. Cooking fires still burning, rice bowls laid out, equipment dropped and left where it fell. In some positions, the dead told the story most clearly of all.

 The wounds on Japanese soldiers in those forward positions were close range wounds fired from a direction that made no sense unless you understood that the Australians had been there invisible, waiting until the moment when waiting was over. Corporal Frank Mlan of the 225th Battalion wrote home after moving through one abandoned Japanese position near Templeton’s Crossing.

 His letter, later quoted by historian Peter Brun in his book, A Bastard of a Place, described what he saw this way. The Japanese had their fires going and their food laid out, and then something hit them so fast they had no time to respond. In some spots, he wrote, you could see where they had been cut down close, all the shots going the same direction, like they had walked into a wall that was not there until it was.

That wall was the close fire approach. That wall had been built not from concrete or sandbags, but from patience and discipline and the willingness to let fear pass through your body like water and keep your finger off the trigger. Anyway, the sounds of those engagements described by survivors on both sides were unlike anything that conventional warfare produced.

The jungle swallowed and scattered sound in ways that made direction impossible to determine. A firefight 100 m away arrived as a muffled eruption that seemed to come from everywhere and nowhere at once. The crack of rifles bounced off dense vegetation and returned from angles that made no tactical sense.

 Men described the specific terror of hearing shooting that seemed to come from behind them even when the enemy was ahead, and the close-range engagements themselves were described consistently as shockingly brief, seconds, not minutes. The position either held or it was overrun and there was almost never anything in between.

 The physical cost on the Australian side was staggering in ways that the casualty figures alone cannot capture. When the 214th battalion was weighed at the conclusion of the campaign, the average soldier had lost 18 kg. These men had been fighting at altitudes above 2,000 m in soaking wet clothing that never dried on quarter rations or less when supply drops failed with feet rotting from constant moisture carrying wounds that infected within hours because the jungle bacteria were as aggressive as everything else in that environment. They had done all of this

while holding their fire until the last possible moment, overriding the most powerful survival instinct a human being possesses. Because a farmer turned brigadier had looked at the jungle and seen something that no map had ever shown. MacArthur’s response to all of this was to rewrite history as it was still happening.

 As the Japanese advance reversed and Australian forces retook Kakakota airirstrip on November 2nd, 1942, the official statements coming out of Brisbane described the reversal in terms of American reinforcement and MacArthur’s own strategic vision. The fighting withdrawal that had bled the Japanese advance to a standstill was framed not as a tactical success but as a failure that had been rescued from outside. Pots remained without command.

The Choco militia soldiers who had formed the backbone of the defense were not celebrated. Their reputation lingered in official circles like a stain that facts could not remove. The alternative approach had already proven its failure in the most definitive way possible. In late August 1942, when fresh reinforcements arrived on the track and commanders attempted to implement the fixed defensive line that MacArthur’s staff kept demanding, the result was the Battle of Isurava.

 The 39th Battalion and the 214th Battalion, ordered to hold a fixed position against Japanese forces that had already spent weeks learning to flow around fixed points like water around stones, sustained catastrophic casualties before a fighting withdrawal became unavoidable. Regardless, Isurava wrote in blood what Pots had been arguing in words.

 Fixed lines in jungle terrain did not slow elite infiltrators. They gave them a target. And yet, the approach that had worked, born in mud and desperation, and the specific geometry of 5 to 10 m engagements, was spreading faster than any official endorsement could have moved it. It was spreading the way all truly useful knowledge spreads in wartime, person to person, mouth to ear, veteran to recruit.

 in the quiet moments between the fighting when men sit together and talk about what actually keeps you alive. By late 1942, the close fire principles developed under pots were appearing in training notes passed between units. They were being discussed at company commander level across multiple formations. They had taken on a life entirely independent of the man who had first organized them into something deliberate and teachable.

The idea had escaped and no generals disapproval could call it back. The war ended in August 1945. Japan surrendered. The men came home and the jungle kept every secret it had been given. But ideas do not surrender with armies. The close fire approach that had been born in the mud and rain of the Owen Stanley ranges did not fold up with the maps and get packed into storage boxes with the rest of the war.

 It moved forward. It changed shape. It put on new uniforms and walked into new jungles and kept doing what it had always done, which was keep men alive in places where the old rules had stopped working. Within 3 years of the Kakakota campaign, the specific principles developed on that track, the measured engagement distances, the interlocking fire zones, the patient geometry of letting the enemy come to you had been formally written into Australian army training manuals.

 The knowledge that had been passed mouth to ear in the darkness of the Owen Stanley’s was now printed on pages and taught in classrooms, stripped of mud and urgency, but carrying the same essential truth underneath. When Australian forces deployed to Malaya beginning in 1948 to fight communist guerrillas in the jungles of the Malay Peninsula, they carried that truth with them.

 The terrain was different in its specific details but identical in its fundamental character. Dense canopy, limited visibility, an enemy that moved through jungle with skill and used it for concealment. The close fire principles were not adapted for Malaya. They did not need to be adapted. They had been designed in the most direct possible way for exactly this kind of fight.

 The Malayan emergency lasted 12 years from 1948 to 1960. And the Australian contribution to it was shaped by the same patient, precise close-range engagement approach that had stopped 13,500 Japanese soldiers on a ridge 48 km from Port Moresby. Then came Borneo. From 1963 to 1966, Australian special forces and infantry units conducted operations in the jungles of Borneo during a conflict called Confrontasi.

A confrontation between Indonesia and the newly formed nation of Malaysia that drew in Commonwealth forces including Australians. British military analysts studying those operations afterward described the Australian jungle warfare performance as among the most technically skilled closeterrain combat ever recorded.

 The lineage of that skill ran in a direct and unbroken line back to 1942. Back to the Owen Stanley’s, back to the specific lesson that the right engagement distance in jungle is not 300 yd. It is the distance at which the jungle stops protecting the enemy and starts trapping him. By the time Australian forces were preparing for Vietnam in the mid 1960s, the jungle warfare school at Kungra in Queensland had become one of the most respected close terrain combat training institutions in the entire Western Military Alliance. American units

specifically requested access to Australian training. They wanted to learn what the Australians knew. And what the Australians knew had been built across decades, from campaign to campaign, jungle to jungle. Each generation of soldiers, inheriting the core insight from the generation before it.

 The 5 to 10 m engagement principle had by this point been tested, refined, and retested across three different major conflicts in three different jungle environments. It had never stopped working, not once. Arnold Pototts did not see any of this formally acknowledged in his lifetime. He returned to Western Australia after the war and went back to farming.

 He was never reinstated to brigade command during the fighting. He received no significant decoration for his leadership on the Cakakota track. The official histories of the campaign written in the late 1950s included his name but not his contribution. The approach he had organized and implemented during the most critical weeks of the most critical campaign in Australian military history was discussed in those histories in general terms credited to collective necessity rather than specific vision.

 The man who had seen what nobody with a clean uniform and a comfortable chair could see was given no particular credit for seeing it. He died in 1968. The Cakakota track was still just a track. Papua New Guinea would not become an independent nation for another 6 years. The word Kakakota meant something to veterans and military historians, but had not yet become the national story it would later grow into.

 The recognition came slowly and then all at once. Historians Peter Brun and Cameron Forbes spent years in the documentary record, the letters, the afteraction reports, the casualty figures, and the captured Japanese documents, assembling the full picture of what had actually happened on the track and who had actually been responsible for the decisions that mattered.

 Their work reached a public that was ready decades after the fact to understand what the Choco soldiers had done and what their brigadier had figured out in the mud. A formal ceremony at the Australian War Memorial in 2004 recognized the 21st Brigade’s performance on the Cakakota track. Pots had been dead for 36 years. Today, more than 4,000 people walk the COD track every year.

 They carry modern packs with lightweight frames and moisture wicking fabric. And they still cannot make the jungle smaller or the ridges shorter. The jungle has not changed. The ridges still rise and fall 2,000 ft within a single kilometer. The rain still falls so hard you cannot hear the person next to you.

 The mud still takes your boots if you let it. People walk the track now because it has become one of the central stories of what Australia is. A story about ordinary people in an impossible place making decisions that the credentialed experts said were wrong and being right anyway in the way that only people in direct contact with reality can be right.

 And this is perhaps the deepest thing the Cakakota story teaches us. the thing that sits underneath all the tactical detail and the casualty figures and the names of the ridges and the battalions. Every institution in every field in every era develops its rules in rooms that are not the jungle. Those rules are written by people who are very smart and very educated and very far from the ground.

 And the rules work until they meet a specific reality they were not designed for. And then they fail and people die. And somewhere in that failure, a farmer or a teacher or a shopkeeper in uniform looks at the dead and looks at the jungle and thinks something that the rules have not yet thought.

 The question this story leaves us with is not really about jungle warfare at all. It is about where you are standing when you decide what is true. It is about the distance between the map and the ground. MacArthur looked at a map and saw cowardice. Pot stood in the mud and saw geometry. And the soldiers who stood inside those positions watching armed men walk toward them through the green dark, counting steps instead of pulling triggers.

 They understood something that no map could ever show. That sometimes the most powerful weapon a human being possesses is the decision not to act until the moment when acting cannot fail. The Cakakota track is still there. The jungle is still watching. And somewhere in the distance between 30 ft and 10 m, a farmer’s idea, dismissed, buried, and nearly forgotten, quietly changed the course of a war, saved a nation, and proved that the bravest thing a soldier can do is sometimes nothing at all.
