How the 7th Australian Division Broke Japan’s Elite Forces

Added: 2026-05-06

[00:00:00]September 1942, the Owen Stanley Range, Papua, New Guinea. By this moment in the war, Japan's South Seas force had taken Singapore, Rabal, the Philippines, and Guam without a single defeat. And now, just 32 mi from Port Moresby, they were about to put Australia itself within bombing range.

[00:00:26]Standing in their way, the Seventh Australian Division, men with no jungle training, dressed for the deserts of North Africa, riddled with malaria and dissentry.

[00:00:39]How did these ordinary farmers and clerks become the first ground force in World War II to break Japan's elite army? Rain falls in heavy sheets through a thick green canopy. High up on a muddy ridge called Yoriwa, an Australian sergeant from the Second 14th Battalion crouches in a shallow pit. His uniform is torn. His boots are full of water. He has not eaten a real meal in 5 days. His hands shake from a fever he cannot shake off. He looks down through the trees and far away in the distance, he can just make out tiny pin pricks of light. Those lights are Port Moresby. They are only 32 mi away. If those lights go out, Australia itself may be next. Behind him, fewer than 300 men are still able to stand and fight. They lean on bamboo sticks because they are too weak to hold their rifles up for long. Many have lost 30 lb. Many have malaria, dissentry, or both. They came to this jungle straight from the deserts of the Middle East.

[00:01:56]Still wearing khaki uniforms made for sand, not mud. In front of him, somewhere in the dripping jungle, a Japanese army is moving closer. Not just any army. This is the Nankai Shitai, Japan's South Seas force. They are some of the best jungle fighters in the world. They have not lost a single battle since the war in the Pacific began. This is the story of how that broken, sick, starving group of Australians did the impossible.

[00:02:30]This is how the seventh Australian division broke Japan's elite forces.

[00:02:36]You came here to find out how a few thousand farmers, shop boys, and office clerks stopped the unstoppable.

[00:02:45]That is exactly the story you are about to hear. To understand why this moment mattered, you have to understand what was happening in the world. By the middle of 1942, Japan was winning everywhere. In just 6 months, they had stormed across the Pacific. They took Singapore, the most powerful British base in Asia. There around 130,000 Allied soldiers were forced to surrender. Then Japan rolled through Malaya, the Philippines, the Dutch East Indies, Guam, and Rabal.

[00:03:25]Each victory came faster than the last.

[00:03:28]Many Allied troops believed the Japanese could see in the dark, climb any tree, and march for days without food or rest.

[00:03:37]In May 1942, the Japanese Navy tried to sail to Port Moresby and take it from the sea.

[00:03:45]American and Australian ships stopped them at the Battle of the Coral Sea. So, Japan tried something no one thought was possible. They would march to Port Moresby by land over the Owen Stanley Mountains on a thin strip of mud and rocks called the Cakakota track. Allied planners had looked at that track and called it impossible. Japan was about to prove them wrong. If Port Morsby fell, the danger was huge.

[00:04:16]Japanese bombers would reach the cities of Northern Australia. Australian Prime Minister John Cirten had already said something no one expected from a leader of the British Empire. He said that Australia now looked to America for help.

[00:04:33]Mothers in Sydney and Melbourne went to bed at night wondering if invasion was coming. So picture that ridge again.

[00:04:41]Picture that sergeant soaked and shaking. Behind him is his country. In front of him is an army that has crushed every other army it has ever met. The Japanese commander, Major General Tomitaro Horry, can almost taste victory. His men can see those same lights, too. They are sure they will be in Port Moresby in a matter of days, but something is about to go wrong for Japan. And it will not happen because of bombs from the sky or fresh American tanks. It will happen because of these men on this muddy ridge in this rain. So the question is simple. How did these starving, sick, forgotten Australians stop the army that no one else in the world had been able to stop? To understand how these men ended up in the jungle, you have to go back to the beginning. The seventh Australian division was born in 1940.

[00:05:44]It was made up of volunteers, every single one. They were farmers from Queensland, dock workers from Sydney, sheep shearers from the outback, and shop clarks from quiet country towns.

[00:05:59]They were part of the Second Australian Imperial Force or Second Aif.

[00:06:06]The division had three brigades, the 18th, the 21st, and the 25th, each with about 3,000 men. Their first real fight was not in the jungle at all. It was in the dry hills of Syria and Lebanon in June and July of 1941 against French troops loyal to the German controlled Vichi regime.

[00:06:32]The seventh division pushed through towns like Damore and fought their way toward Damascus.

[00:06:39]They were tough, proud, and battle tested. After Pearl Harbor and the fall of Singapore, Australia begged for them to come home. They were rushed back across the world. They had trained for desert war. Now they were about to be thrown into a wet green hell. Most had never seen a rainforest in their lives.

[00:07:03]The leaders mattered just as much as the men. Major General Arthur Allen, known as Tubby, was their commander when the Cakakota fighting began. He was quiet, careful, and steady. His men loved him.

[00:07:19]Later, Major General George Vasey would take over, sharper, faster, more aggressive. There was Brigadier Arnold Pototts of the 21st Brigade who would have to fight the first big battle on the track with almost nothing. And above them all stood General Thomas Blay, the top Australian commander being squeezed by the famous American general Douglas MacArthur in Brisbane. Now meet the enemy. The name Kai Chitai was led by Major General Horry. The heart of his force was the 144th Infantry Regiment called the Coochi Regiment. These men had spent years fighting in China. Horry also had the 41st Infantry Regiment plus mountain artillery units. At their peak, around 13,500 Japanese soldiers were on or near the track. Their plan was simple. Move fast.

[00:08:24]slip around the enemy, surround them, wipe them out. They had done it everywhere else, but there was a third enemy on the Cakakota track, and this one had no flag. It was the land itself.

[00:08:39]The track was a thin trail of mud that snaked 96 km or about 60 mi through some of the worst land on Earth. The mountains rose more than 7,000 ft. Some areas got more than 250 in of rain a year. Malaria, deni fever, scrub typhus and dissentry struck men down faster than bullets. There were no roads, no trucks. Every bullet, biscuit, and bandage had to be carried by hand on the backs of brave paporters who became known as the fuzzy wooy angels or dropped from low-flying planes. Before the Seventh Division arrived, the only force standing in Japan's way was the 39th Battalion. Young militia boys from Victoria hardly trained at all. The tough AIF veterans had laughed at them and called them chocolate soldiers. But those boys held on at a tiny mountain village called Isurava.

[00:09:45]They bled. They died. They held. And they bought just enough time for the men of the seventh division to climb the track. The real fight was about to begin. By August 1942, the news was getting worse by the hour.

[00:10:03]The Japanese had pushed past the Australian outposts at Awala, Koko, and Deniki. Now the men of the 21st brigade were being rushed up the track to plug the hole. They came straight off the ships. Some had not even been issued jungle gear, still in the dusty khaki shirts and shorts they had worn in the Middle East. The first big test came at Isurava between August 26th and August 31st, 1942.

[00:10:37]The 214th and 216th battalions arrived under heavy rain. The jungle was so thick men could not see 10 ft ahead.

[00:10:47]Mortar shells came whistling down through the trees. The smell was a mix of wet leaves, rotting wood, gunpowder, blood, and unwashed men. Soldiers fought at distances of five or 10 paces. They could see the enemy's eyes. They could hear them breathing. It was during this fight that a young soldier named Bruce Kingsbury did something no one who saw it ever forgot. The Japanese had broken through a weak spot in the line.

[00:11:20]Kingsbury grabbed a Bren gun, jumped up, and charged straight at the enemy. He fired from his hip as he ran. He cut down many Japanese soldiers and broke their attack. Moments later, a sniper shot him dead. He was 24. He would be given the Victoria Cross, the first one ever earned in the defense of Australian territory. But brave deeds alone could not stop a force four or five times larger. So Brigadier Pots gave a hard order. Fall back. Fight. Fall back again. This was called a fighting withdrawal. For more than 60 kilometers, the men of the 21st Brigade pulled back ridge by ridge. They fought at Yora Creek at Templeton's crossing on a sharp peak called Brigade Hill. Every step backward was paid for in blood. The conditions broke men faster than the bullets did. Dysentery was so bad that some soldiers cut the seats out of their trousers.

[00:12:25]Many lost more than 30 lbs in just a few weeks. Their faces turned yellow from Artbrin, the medicine that fought malaria. Their feet rotted inside their wet boots. They were down to half a hard biscuit a day. One soldier wrote, "We are like ghosts. We carry the dead in our eyes." The Japanese were suffering, too. Captured letters told a strange story. One Japanese soldier wrote, "We are fighting in a green hell. The Australians give no ground without making us pay for every meter." Their supply lines were stretched too far. But Horry pushed his men forward anyway. Far away in Brisbane, MacArthur was furious.

[00:13:14]He could not understand why the Australians kept falling back. He told his staff that the Australians won't fight. It was an unfair thing to say. He had no idea what those men were going through. By the middle of September 1942, the brigade that had started at full strength of about 2,000 men had fewer than 300 still able to stand. The Japanese, even with their losses, kept coming. They climbed onto Oura Ridge, the last high ground before the city.

[00:13:51]The whole campaign now hung on a single fragile thread. And then on September 16th, 1942, something amazing happened. The Japanese stopped. Hi looked toward Port Moresby.

[00:14:07]So close he could almost touch it and gave the order no Japanese commander wanted to give. Halt. Dig in. Wait. The reasons were piling up like stones.

[00:14:19]First, the Japanese supply line had snapped. Some Japanese soldiers were down to one rice ball a day. Some were eating leaves and grass. Second, far to the east, Japan had just suffered another disaster. At a place called Mil Bay, between August 25th and September 7th, Australian militia and AIF troops had crushed a Japanese landing force. It was the very first time in the whole Pacific War that a Japanese ground attack had been beaten back into the sea. Third, and worst of all, the high command in Tokyo had decided that Guadal Canal was now more important.

[00:15:03]Fresh men and supplies meant for Hi were being sent there instead. He was on his own. So, the order came down. Pull back.

[00:15:12]For the first time in the entire war, a Japanese army on the attack had been stopped on land by a defending force.

[00:15:20]The myth was cracking. Now the seventh division got to push forward. Major General Allen sent the fresh 25th Brigade led by Brigadier Ken Ether up the track. The 16th Brigade joined them.

[00:15:37]The men who had been retreating for so long now turned around and chased the Japanese back through the jungle ridge by ridge.

[00:15:46]The first big clash came at Yora Creek between October 22nd and October 28th.

[00:15:53]The Japanese were dug into the side of a steep mountain. The Australians had to attack uphill in cold rain through slippery mud. They fired their rifles.

[00:16:05]They threw grenades. When that was not enough, they fixed bayonets and charged.

[00:16:11]Men fought handto hand. Some grabbed each other and rolled down the slope, fighting as they fell. By this time, a sad and angry thing had happened.

[00:16:22]General Blamey, pressured by MacArthur, had relieved Tubby Allen of his command.

[00:16:28]The men of the seventh division loved Allen. They felt he had been treated unfairly. In his place came Major General Varsi, sharp and fast and aggressive. Vasy had not chosen the job, but once he had it, he meant to win with it. V's chance came at the battle of Oi Gerari between November 4th and November 11th, 1942.

[00:16:55]By now, the Japanese had pulled back to the lands where the ground was flatter but covered in swamps and tangled forest.

[00:17:04]FI did something his desert training had taught him well. While part of his force pushed straight at the enemy, he sent another part wide around the side, sneaking through the jungle to cut the Japanese off from behind.

[00:17:20]When the trap snapped shut, the Japanese force broke. Their organized retreat turned into a panicked scramble. The proud Southseas force was shattered.

[00:17:32]Eight days later on November 19th came the strangest moment of all. General Horry, the man who had led Japan's golden run across the Pacific, was trying to escape across a swollen river called the Kumusi.

[00:17:48]He climbed onto a small raft made of logs. The river roared. The raft tipped.

[00:17:56]As the water pulled him under, witnesses said he shouted, "Tenno Banzai, long live the emperor." Then he was gone. Captured Japanese diaries from those weeks said something no one had ever read before. One soldier wrote, "We who were never to retreat are retreating. We who were never to be defeated are defeated."

[00:18:21]The unbeatable army was no longer unbeatable. The seventh division had broken the spell. But the seventh division was not done. The Japanese, even with Hi dead, still had fight left in them. They pulled back to three small villages on the northern coast. Gona, Buna, and Sanandanda.

[00:18:43]There they dug in. They built thick log bunkers. They placed machine guns at sneaky angles. Fresh Japanese troops landed by ship to defend these places.

[00:18:54]The men of the seventh division, already worn down to bone, now had to dig them out one by one. Many of the old Kakakota veterans said this part was even worse than the track. Goner fell first on December 9th, 1942.

[00:19:13]The 21st and 25th brigades, the same men who had bled on Isarava, made the final push. The fighting was so close that grenades were thrown back and forth like baseballs.

[00:19:27]When the village was taken, Brigadier Ivan Dohi sent a short message back to headquarters. It said only gone. Two simple words for a victory that had cost almost 750 Australian dead and wounded.

[00:19:44]Sanandanda was the worst of all. Salty swamp water came up to a soldier's waste. The grass was tall and razor sharp and full of hidden Japanese snipers. Mosquitoes came in clouds so thick that men breathed them in.

[00:20:02]Veterans of World War I said Sanin was worse than Passandale, and that was the worst thing they could think of to say.

[00:20:11]The cost was almost too heavy to count.

[00:20:15]By the end of the campaign, the seventh division had thousands of battle casualties. For every man killed by a bullet, three more were knocked out by sickness. Whole companies were emptied not by the enemy, but by malaria, dysentery, and scrub tyifus. The Japanese suffered even worse. Of the roughly 13,500 men Horry had brought into the campaign, very few ever made it home. The rest lay dead in the jungle, in the swamps, or on the beaches. Some had starved. Some had taken their own lives rather than be captured. Captured diaries showed that some had been forced to eat the bodies of their dead comrades just to stay alive. Reactions to the victory were mixed. MacArthur, who had once said the Australians won't fight, now praised them in his news reports. But he wrote those reports in a way that made it sound like Americans had done most of the work. When in truth, on the Cook track, the fight had been almost entirely Australian. The men noticed.

[00:21:28]They never forgave him. Then came an even sadder moment. General Blamey came to speak to the surviving men of the 21st brigade. These were the heroes of Isurava.

[00:21:42]They expected thanks. Instead, in front of his old soldiers, Blamey told them in effect that the rabbit that runs is the rabbit that gets shot. It was as if he was calling them cowards for retreating even though the retreat had saved the country. Some men cried. Some turned their backs and walked away. Many never spoke Blamey's name again as long as they lived. But out of all the pain, there were small, bright moments of kindness, too. Australian medics still bandaged the wounds of captured Japanese soldiers. The fuzzy, wuzzy angels carried wounded Aussies down the track for days, never dropping them. One photograph would become famous around the world. It showed a blinded Australian soldier named Dick Whittington being gently led by the hand by a Papuan man named Raphael Ombari.

[00:22:41]Two strangers from two different worlds holding hands in a jungle at the edge of the war. When the smoke cleared on the beaches of Buna and Sanaandanda in January 1943, the world looked different. Papua became one of the first places the Allies had taken back from Japan in the entire war.

[00:23:03]The map had started to shrink for them.

[00:23:06]The plan to cut Australia off from America was dead.

[00:23:11]Combined with the long bloody fight the Americans were having on Guadal Canal at the same time, the Papua campaign marked the moment when the whole Pacific war turned. Before these two campaigns, Japan was on the attack everywhere.

[00:23:28]After them, Japan would be on defense for the rest of the war. The lessons learned in the jungles of Papua changed how the allies fought from then on.

[00:23:39]Before Cucakota, no western army really knew how to fight in thick jungle. Big formations did not work. Tanks could not move. The seventh division had to learn it the hard way. They figured out how small groups of soldiers could move through the trees and find the enemy.

[00:24:00]They learned how to use light Bren machine guns up close.

[00:24:04]They worked out how to use planes to drop food and ammunition right where it was needed. These hard one lessons would later be studied by American Marines fighting on islands across the Pacific and by British soldiers fighting in the jungles of Burma. For Australians, news of the Cakakota victory swept through the country like fresh wind. Their sons had not just held the line. They had won. They had stopped the army that had taken Singapore, Malaya, and the Philippines.

[00:24:40]Across kitchen tables in cities and quiet country towns, people lifted their heads a little higher. For the Japanese, the effect was the opposite. For the very first time, ordinary Japanese soldiers began to wonder. captured letters home, never sent because their writers were dead, showed something new and dangerous.

[00:25:05]Doubt. The crack in the wall was small, but it was there. And cracks in walls only grow. Even the Japanese later admitted what had happened. After the war ended in 1945, Lieutenant General Harukichi Hayakutake said two big mistakes had cost Japan its southern push. One was failing to send enough supplies to Horry. The other was guessing wrong about the Australians.

[00:25:34]They had thought the Australian soldier would crack under jungle conditions.

[00:25:39]They had thought wrong. A late war Japanese army assessment described the Australian soldiers as among the toughest jungle fighters the empire had faced. Behind every big battle, there are small human stories. Take Bruce Kingsbury, the young soldier who charged the Japanese at Isarava with his Bren gun blazing. He was 24 when he died. He came from Melbourne. His family waited for letters from him every week. Today, his Victoria Cross is on display at the Australian War Memorial in Canberra.

[00:26:19]Then there is Brigadier Arnold Pototts, the man who saved Port Moresby with his fighting withdrawal. He had pulled his men back step by step, fighting all the way, never letting the line break. He had saved a country, and his reward was to be sacked.

[00:26:39]Blamy, under pressure from Macarthur, removed him from his command. Pots went quietly home to Western Australia. He never asked for praise. He died in 1968, his name still half buried under unfair words.

[00:26:58]Only after his death did historians give him the credit he deserved. Major General Varsi kept fighting through 1943 and 1944, leading his men into more jungle campaigns in the Markham and Ramu valleys. But Vi would never see victory in the war he had helped win. On March 5th, 1945, just months before Japan surrendered, his plane went down off the coast of Canes. There were no survivors. Private Dick Whittington, the blinded soldier in that famous photograph, did not have long to enjoy his rescue. The head wound that took his sight had been suffered at Boona. He died of scrub typhus in February 1943.

[00:27:48]Raphael Oimari, the kind man who had led him by the hand through the jungle, lived a long, quiet life. In his old age, the Australian government finally invited him to visit Australia. He shook hands with prime ministers.

[00:28:05]He passed away peacefully in 1996.

[00:28:08]There was also Stan Bissy of the 214th Battalion. Stan had a younger brother, Butch, who was an officer in the same battalion. At Isurava, Butch was hit by machine gun fire and badly wounded. Stan held his brother in his arms through the long dark night while the rain poured down. Butch slowly slipped away, talking quietly with Stan about home, about their parents, about the songs they used to sing. By morning, he was gone. Stan survived the war and lived to be 98, dying in 2010 as one of the very last Cakakota officers still alive. And then there were the Fuzzy Wuzzy Angels.

[00:28:57]Thousands of papu and men, often pressed into service, carried wounded soldiers for days through the jungle. They never dropped a man. They kept the dying warm.

[00:29:08]For decades, they were forgotten. Only in 2009 did Australia finally award them a special commemorative medallion.

[00:29:17]Decades too late for most. Today, more than 80 years after the last shot was fired at Sanananda, the Kakakota track is still there. The mud is still there.

[00:29:29]The mountains are still there. But now, instead of soldiers, the track is full of walkers. Every year, thousands of Australians fly to Papua New Guinea to walk the same trail their grandfathers fought across. Some are students. Some are office workers looking for meaning.

[00:29:50]Some are old men in their 80s trying to find the spot where a brother or a father fell. The most famous memorial is at Isarava on the very ground where Bruce Kingsbury made his charge. Four black granite pillars rise from the earth. Each carved with a single word.

[00:30:10]Courage. Endurance. Mesship. sacrifice.

[00:30:15]Together, they sum up everything the men of the Seventh Division stood for. For Australia, this campaign sits beside Gallipoli as one of the great founding stories of the nation's military spirit.

[00:30:29]But there is one big difference.

[00:30:31]Gallipoli ended in defeat. Kakakota ended in victory. A victory that helped save the homeland itself.

[00:30:40]The values it taught, especially mateship, meaning the deep loyalty between friends in hard times, have become part of how Australians describe themselves to the world. Out of the war's pain came something good and lasting. In 1975, Papua New Guinea became an independent nation. Australia was its closest helper through that change. The friendship that began with a Papuan man named Raphael leading a blind Australian named Dick by the hand is still alive today. Even Japan and Australia who fought each other so bitterly have built a deep peace. The men who once tried to kill each other in the jungle in their old age sometimes met and shook hands. They cried, they bowed, they forgave. The last of the Cocod veterans passed away in the 2000s.

[00:31:38]Almost none of them spoke about glory.

[00:31:41]They spoke about waste. One old soldier said, "No one should ever let themselves believe war is anything but waste." In the end, the deepest meaning of the story is this. They were not supermen.

[00:31:57]They were farmers and clerks and shop boys from Melbourne and Adelaide and Perth.

[00:32:03]And on a muddy ridge in a jungle no one had heard of, they did what no one had done before. They made the unbeaten army turn and run. A single slouch hat lies in the mud at Isurava, and that is
