Why Japanese Generals Despised Australian Soldiers… Until They Had To Fight Them

Added: 2026-06-03

[00:00:00]In the weeks after Singapore fell, somewhere in a Japanese headquarters, a staff officer would have been working through the surrender returns. The numbers alone were staggering. The great British fortress in the east had capitulated on the 15th of February, 1942. And into the prison cages went tens of thousands of men, British, Indian, and Australian. The largest surrender of a British-led force in history, handed over in a matter of days. For a command culture that had been taught to read surrender as a confession of moral weakness, the lesson wrote itself. The western enemy talked a great deal about fortresses and empire.

[00:00:38]And then when the pressure came in close and personal, he put his hands up. That conclusion did not stay in a file. It traveled. It shaped how Japanese commanders planned the next phase of the war. How confidently they pushed, how little margin they left themselves. And a few months later on a wet mountain track in Papua, it started costing the men. That gap between what Japanese command believed about Australian soldiers in February and what their own reports were recording by November is what I want to walk through with you.

[00:01:12]Not whether the Japanese hated us in some emotional sense, whether their assumptions survived contact. Because the ugly part of this isn't a clash of feelings. It's a command culture that came into the Pacific War certain it understood the enemy and an enemy who kept refusing to behave the way the certainty required. Let me start with where the contempt came from because it wasn't pulled out of the air. It was built deliberately over years. At the center of it sat the Japanese army's attitude to surrender. In 1941, the war minister issued a field code for soldiers, the Senzhin Kun, the instructions for the battlefield, and among its lines was the pressure on a man never to suffer the disgrace of being taken alive. I'd be cautious about hanging the whole edifice on one document. Historians have argued for a long time that the no surrender ethos was less an ancient samurai inheritance than a modern militarist construction hardened deliberately and then dressed in old language to make it feel unarguable. But by 1942 it was real in its effects. It told a Japanese soldier that to be captured was to be already dead in every way that mattered. And it told him by extension what to make of an enemy who chose that death that such a man had thrown away his honor and with it most of the consideration a soldier might otherwise be owed. That one belief did enormous damage in this war and it sits underneath nearly everything that follows. On top of the surrender doctrine ran something crudder, a racial and imperial confidence that threaded through a great deal of Japanese military thinking. Western troops in the propaganda picture were decadent, softened by comfort, dependent on their machines. Colonial soldiers of a distant dominion sat lower still in that hierarchy. The assumption was that men from prosperous, easy societies lacked the spiritual hardness for a long grinding fight and that they could be broken by uh speed, by shock, by getting in close where their equipment and their artillery couldn't save them. It was an article of faith more than a tested conclusion. But faith in an army becomes doctrine and doctrine becomes the plan.

[00:03:29]And then through the opening months of the Pacific War, the world appeared to confirm every word of it. And the campaign down the Malay Peninsula was from the Japanese command's point of view an almost perfect vindication.

[00:03:43]Yamashita's 25th Army moved fast through country the defenders had been told was impossible. infiltrated and flanked positions that were meant to hold and kept the Allied force perpetually off balance and falling back toward the island. They used bicycles where they had no transport. They moved at night, pressed when the British and Australian and Indian units expected a pause and they kept the initiative the entire length of the peninsula. The defenders fought hard in places and bravely and still kept losing ground. When Singapore itself surrendered, the Australian 8th Division went into captivity almost entire somewhere around 15,000 men. To the Japanese staff drawing the lessons, the pattern looked settled. The enemy had numbers, equipment, a fortress, and the prestige of an empire behind him, and none of it had held. The contempt didn't merely survive Singapore.

[00:04:39]Singapore appeared to prove it correct and a belief that reality keeps confirming becomes very hard to shift.

[00:04:47]This is the part I'd ask you to sit with because it matters for everything afterward. The Japanese command's confidence in early 1942 was not arrogance floating free of the facts. It was built on a run of genuine hardone victories against real opponents. Hong Kong, the Philippines under pressure, the Dutch, East Indies folding, Malaya, Singapore. Their soldiers were tough, their planning was bold, their tempo was punishing. When a staff officer concluded that the Western enemy would break under close pressure, he had a season of results behind the conclusion.

[00:05:21]The danger wasn't that the assumption was stupid. The danger was that it was about to be applied with total confidence to a kind of fighting and a kind of enemy where it no longer held.

[00:05:34]And confidence built on success is exactly the confidence that slow us to notice when the ground beneath it has changed. Before we follow that confidence up into the mountains, a quick word, we're getting close to 5,000 subscribers now. If you think these Australian wartime stories deserve careful handling, I'd be glad to have you along. That's all. Let's get back to it. The men who went into the cages after Singapore met the surrender ideology straight away in the way they were treated. They were not prisoners as their own army understood the word. Held under rules, fed, protected. They were the dishonored. And the gap between those two ideas would over the next 3 years kill thousands of them. Held first in Changangi, then scattered to the places whose names still carry weight in this country. But that part comes later in what I want to tell you. Because by the middle of 1942, the Japanese command's attention had already moved south to Papua and to a force that was about to test the certainty Singapore had handed them. That force was the South Seas detachment, the Nankai Shitai under Major General Tomitaro Hi. It came ashore on the northern coast of Papua in July 1942 around Gona and Buuna with the object of crossing the Owen Stanley Range by the Overland track and taking Port Moresby from the rear. On paper, it was a reasonable plan held by a capable, experienced formation. Horry's men were not amateurs. They were tough, disciplined, and freshly confident, carried on the same momentum that had swept down through Southeast Asia. The staff assumption was straightforward. A hard, fast overland push would carry them across the range and onto Moresby before the defenders could organize anything that mattered. The first phase of the advance did nothing to shake that assumption. The Australians first in their path were militia. the 39th Battalion, young, undertrained, the kind of unit the AIF veterans like to call Choos chocolate soldiers on the theory they'd melt in the heat. First contact came around Aala and Code in late July and the Australians fell back. They fell back a long way over weeks through Deniki and Isarava and on toward the high passes. from a Japanese command map that looked exactly like Malaya again.

[00:07:58]The soft colonials giving ground, unable to hold a line. But the reports coming back up the track carried a complication. The map didn't show. The Australians were retreating, but they were not dissolving. They would give up a position, fall back to the next defensible ridge, and turn and fight again and then again. That distinction between a withdrawal and a route is the whole hinge of the COD campaign. And it's the thing the early certainty could not account for. A routed enemy stops costing you. A withdrawing enemy who keeps reforming bleeds you the length of his retreat and bleeds you worst when you're the one who has to keep attacking up a single muddy track to dislodge him.

[00:08:40]The hardest of that bleeding came at Isarava in late August. the 39th by then commanded by a calm and very good officer named Ralph Honer held the position until the veterans of the seventh division's 21st brigade under Brigadier Arnold Pots could come up the track. What followed there over several days was a battle the Japanese had to win to keep their timetable. And in the end they did win it. They took the ground but they took it at a price. the plan had not budgeted for against men who were outnumbered, half starved, soaked, and sick, and who still made them pay for every yard. From Hurry's headquarters, the position would still have read as success on paper. The detachment was advancing. What the paper couldn't yet say was that the timetable was slipping and the cost per ridge was climbing. And here I'd ask you to hold the Japanese command situation in your head honestly because it's easy to turn them into fools and they weren't. Hi's detachment kept advancing. By the standards of a situation report, it was succeeding, pushing the Australians back through Yora Creek and over Brigade Hill on toward Yori Bwa, getting close enough to Port Moresby that some accounts have the forward troops able to see the glow of it at night. They reached their objectives doorstep. The trouble was the condition they reached it in. And the condition tells you more about the failure of the assumption than any single battle does. The ground is the thing you cannot leave out. The Owen Stanley's are not scenery here. They're the deciding factor, and they were a factor that the early planning had badly underweighted. The track ran up and down ridge after ridge through cold, wet mountain jungle, narrowing in places to a single file of mud, climbing thousands of feet and dropping again. Everything had to be carried. For the Japanese, that meant their supply line lengthened behind them with every ridge they took, strung back over the mountains to the beaches at Buna and Gona, and it could not deliver enough. Horry's men advanced into hunger. The staff work that had carried them so confidently through Malaya, where roads existed, where supply could keep pace with a fast advance, simply could not solve the arithmetic of feeding an army across that range against an enemy who made them fight for the road the whole way.

[00:11:02]The assumption of momentum had become a trap. The faster they pushed, the further they outran the food. The Papuan carriers belong here, and not as a sentimental footnote. The men Australians came to call the fuzzy wuzzy angels. Baltry, a name that flattens a far more complicated and often coerced reality, moved the supplies and carried out the wounded that no vehicle and no aircraft could reliably handle. This was a war fought through Papuan country across Papuan villages and gardens at a cost to Papuan people that rarely makes it into the Australian retelling. Their homes became a battlefield they had not asked for. Their labor was leaned on hard by both the army that needed it and the circumstances that compelled it. And the terrain that strangled H's supply was the same terrain that local knowledge and local labor helped the Australians work within. You cannot understand why the Japanese advance ran out of strength at Yoriwa without all of that sitting underneath it. In the end, Horry was ordered to withdraw. Part of that was the wider war. The Americans had landed at Guadal Canal and Japanese strategic priorities were shifting, draining the resources the Papuan thrust depended on. Part of it was the plain fact that the detachment had outrun its supply and could not be sustained where it stood within sight of the prize. The Australians reinforced and now pushing forward followed the retreat back over the range and retook Cakakota in early November. Horry himself did not survive the campaign. He drowned crossing the Kamoosei River during the withdrawal.

[00:12:39]The man who had led the confident advance toward Morsby ended it dead in a Papuan River. His force broken not by a single decisive battle, but by the cumulative cost of an enemy who would not break on ground that punished the attacker with a supply line that finally failed. The certainty that came out of Singapore had met something it could not plan around and the man carrying it was gone. That was the first real correction to the assumption the early victories had handed Japanese command. It wouldn't be the last. And the next one came in a form the doctrine had even less room for. While the Cocoda fighting was at its height, the Japanese mounted a landing at Mil Bay on the eastern tip of Papua to seize the airfields there. The men defending it were mil force under Major General Sirill Claus, a mix of Australian militia and AIF brigades with two squadrons of RAF Kittyhawks 75 and 76 flying from strips in conditions that almost defy description. Mil Bay in the wet is a place of bottomless mud and rain that seems to hang in the air rather than fall. Coconut plantations turn to swamp. The Japanese landing force naval troops came in at night in confusion into that mud. They brought light tanks ashore and the tanks bogged.

[00:14:03]The assault was pressed hard toward the airfields and it was held and then it was thrown back. By the 7th of September, the Japanese were evacuating their survivors. Milner Bay was the first defeat of a Japanese amphibious landing in the Pacific War. And the reason it mattered to command on both sides runs deeper than the tactical result. Real as that was, an amphibious assault was precisely the kind of operation Japan had been executing with confidence across the theater. It was a tool the command trusted, a method that had worked again and again. And it had failed. Not against a great p's main army, not in a setpiece battle the staff could rationalize, but against Australian militia and a couple of squadrons of fighters in the mud. The Japanese did not come away from Mil Bay admiring the Australians. They came away with proof that an operation type they had relied upon could be stopped cold.

[00:15:02]And that's a far more uncomfortable lesson for a staff to absorb than a single lost battle. because it doesn't just cost you a position, it puts a question mark over your method. Field Marshall Slim, looking back later, was clear that the men who did it had handed the Japanese their first undoubted defeat on land, and that the wider Allied cause owed them a debt for the morale it bought at a moment when very little else was going right. Milner Bay carried something darker, too. Something that fed straight into what came next.

[00:15:34]During and after the fighting, Japanese troops killed and mutilated captured and wounded Australians and Papuan civilians as well. When the Australians retook that ground and found what had been done to men they knew, it changed something in them. This is the point where the contempt that began as command doctrine starts becoming personal on the Australian side and the war begins to turn into something neither army's home society would have recognized as within the rules. If Kakakota complicated the Japanese assumptions and Milan Bay broke one of their trusted tools, the fighting on the northern beaches through the end of 1942 and into the new year buried the idea of the soft enemy for good. Buna, Gona, Saninanda, the Beach Head battles were where Japanese defensive doctrine met Australian and American endurance.

[00:16:27]And the result was as ugly as anything in the Pacific. The Japanese dug in along the coast in bunkers built of coconut logs and earth and sand cited with real skill, almost invisible until they opened fire and held by men whose no surrender culture now worked in reverse. The same ideology that had made them contemptuous of the enemy at Singapore now told their own troops to die where they stood rather than yield a position. From a Japanese command point of view, that was the doctrine functioning as designed. Defenders who would not break, who would make the attacker pay in full for every meter, and the attacker did pay. Australian and American troops had to reduce those bunkers one at a time at close range, often with grenade and bayonet, in swamp and heat, with little room to maneuver and less cover. The command friction in those weeks was severe, and it ran in several directions at once. The American 32nd Division and the Australian 7th fought there in an uneasy partnership.

[00:17:32]two armies with different training, different experience, and very different states of readiness for that kind of fighting. The Americans were largely new to it. The Australians had been bled into it on the track. MacArthur's headquarters, far to the rear, in comfort, applied pressure that bore little relation to what the ground actually allowed, demanding speed from formations that were drowning in mud and disease. Commanders were sacked.

[00:17:58]Reputations were made and broken on results that owed as much to the terrain and the sickness as to anyone's generalship. And on the Japanese side, the defenders were under orders that amounted to a sentence. Hold to the end, expect no relief, expect no withdrawal.

[00:18:14]Both command structures in their own ways were spending men against a problem that the planning had underestimated.

[00:18:22]And the ground again was killing men on its own account. Disease at Bunaona was not a side note. The casualty returns show malaria, dissentry, and scrub typhus taking men out of the line in numbers that rivaled the bullets.

[00:18:37]Soldiers fought those battles already ill, already exhausted, shaking with fever. And the medical evacuation chain strained and sometimes broke under it.

[00:18:47]The Japanese defenders cut off and unsupplied had it worse. Starving, diseased, ordered to hold to the end.

[00:18:55]And many of them did exactly that.

[00:18:57]Fighting from bunkers until the bunkers were destroyed on top of them. What I'd put to you about Bunagona is this. It's the place where the line between contempt, endurance, and cruelty gets very hard to see. The Japanese held with a tenacity born from the same culture that had once let them dismiss the Australians as soft. The Australians attacked with an endurance the propaganda had simply got wrong about.

[00:19:23]And the experience of clearing those bunkers, of an enemy who would not surrender, who fought from concealment after a position seemed taken, who sometimes feigned surrender and then killed the men who came forward to accept it. taught Australian soldiers a set of lessons that made them by the end harder and less merciful than they'd begun. The fighting was teaching both sides to expect nothing. And an army that expects nothing eventually offers nothing, which brings me back to the prisoners and to why Australian hatred of the Japanese hardened into something it never quite became for the Germans.

[00:20:01]The men taken at Singapore were the leading edge of it. From Changi, the eighth division and the other Allied prisoners were dispersed to the work the surrender ideology had made thinkable up the Burma Thailand railway where Australian prisoners among many others were worked and starved and beaten through disease-ridden cutings and thousands died into the hell ships packed below decks in conditions that killed before they ever reached land.

[00:20:28]And later in Borneo, the death marches out of Sandacan, where of the prisoners held and force marched in the war's final stretch, only a handful of Australians survived. All of them men who had escaped. I won't walk you through Sandacan again. It has its own telling and deserves far better than a paragraph here. The point for this story is narrower and harder. The treatment of Australian prisoners was not an aberration that ran against Japanese military culture. It flowed directly from it from the belief that a man who surrendered had already thrown away the standing that would have protected him.

[00:21:04]Conduct followed ideology. The source trail is far stronger on that conduct than on any individual commander's private feeling. And conduct is what reached the men still fighting because it did reach them not in clean detail but in rumor in fragments in the bodies found at Mil Bay in the dread of what was happening to mates who had marched into captivity at Singapore and simply vanished into a system nobody could see into. It accumulated and it curdled and it changed the way Australian soldiers fought. I'm not going to dress up where that led in that climate. Some Australians stopped taking prisoners.

[00:21:43]Some killed Japanese who were trying to surrender. The source record supports that this happened not as policy, not universally, but often enough that it can't be filed away as a handful of bad men on a bad day. Mark Johnston, who has studied Australian soldiers attitudes to their enemies more carefully than most, traces how the hatred of the Japanese ran harder and colder than anything the same men had felt fighting Germans in the desert. The reasons the soldiers gave themselves were real to them. They had learned not to trust a Japanese with his hands up because they had watched that gesture turn into a grenade. They were carrying rage about their prisoners that had no clean place to go. And the doctrine of no surrender on the Japanese side meant genuine captures were rare and the few prisoners taken were treated with deep suspicion. I won't call that justice and I won't use it to score a tidy point about both sides being the same. Killing a man who is trying to surrender is a war crime. Whoever does it and whatever he has seen and however reasonable his fear. The Australians who fought this war did not always fight cleanly. And the men who were actually there were generally more honest about that than the memorials have ever been.

[00:23:00]The Japanese command's contempt and the brutality that flowed from it helped manufacture a war in which Australian soldiers came to expect less and less humanity from the enemy and then often enough gave less back. That's not a story with a hero's shape. It's a story about how fast the floor gives way once an army has been taught that the man opposite has forfeited his claim to be treated as fully human and how that teaching spreads from the side that started it to the side that suffered from it. So what had actually changed in the Japanese command's understanding by the time the New Guinea fighting ground on into 1943?

[00:23:41]Not affection. There was none. And it would be too neat to say the contempt had simply flipped into fear or respect.

[00:23:49]What the record shows is adjustment more clearly than emotion. A Japanese commander could still hold the cultural certainty that surrender was disgrace, that western and colonial troops were soft in some essential way and at the same time keep a separate professional ledger that read very differently. That ledger recorded ground that took longer to gain than planned. Supply lines that failed under pressure the staff had underestimated. An amphibious operation that did not succeed against second line defenders. Casualty returns heavier than the early campaigns had taught them to expect. Defenders and now attackers who would not break on the timetable the doctrine assumed. A commander can despise an enemy in his ideology and still change his plans because of him.

[00:24:39]Armies do it constantly. It's one of the most ordinary things a staff does. The contempt and the caution can sit in the same headquarters in the same report, sometimes in the same man. And through the second half of 1942, that's exactly what happened. The feeling didn't change. The arithmetic did. And in war, when the feeling and the arithmetic disagree, it's the arithmetic that ends up shaping the orders. Picture the kind of report that came out of that, not a confession of admiration. The doctrine left no room for it, and no staff officer was going to write it down, even if he felt it. What it recorded instead was cost, distance gained, and how dearly it had been paid for. rations that never arrived over the range. Men lost to the mountains and the bunkers and the disease in numbers the plan hadn't allowed. An enemy who fell back and reformed and was still there, still in contact, still making the next ridge expensive. The language of such a report stays cold. It does not salute the Australians, but it has stopped describing them as the easy enemy the surrender numbers from Singapore once promised. And that quiet change in the paperwork from contempt to cost accounting is the truest measure of what the fighting in Papua had done to the certainty the Japanese command carried into it. The contempt outlived the campaign. So did the Australian hatred carried home by a great many veterans and never put down. Neither side came out of New Guinea thinking better of the other in any way you'd call generous.

[00:26:12]What had changed was narrower and colder than that. and it lived in the operational record rather than in anyone's heart. The enemy the Japanese command had been certain it understood in February had by November become a column on a casualty return that would not stop costing them. And a staff that keeps writing that column long enough eventually plans around it.
