1. Lead

The Battle of Tinian, fought from 24 July to 1 August 1944, was one of the most skilfully executed amphibious landings of the Pacific War, and one of the most consequential. In eight days, two divisions of the United States Marine Corps took the island of Tinian, in the Mariana Islands, at a cost of 328 killed — a small price beside the slaughter at Saipan, Tarawa and Peleliu. The victory mattered because of what the Americans built on Tinian: North Field, the largest airfield in the Pacific, from which, a year later, the bombers Enola Gay and Bockscar took off to drop the atomic bombs on Hiroshima and Nagasaki.

Tinian is remembered by military historians as a textbook operation, the battle in which the Marines applied everything they had learned in three years of island fighting. The landing was a deception: the Japanese expected the Americans at Tinian Town, in the south, and the Marines landed instead on two narrow beaches in the north-west, beaches the Japanese had thought too small and too difficult to use. The Japanese commander, Colonel Kiyochi Ogata, had prepared a strong defence, but his forces were outnumbered, outgunned and caught in the wrong place, and the battle was over in a week.

3. Background

3.1. The Strategic Background

Tinian was the second island in the Marianas to be invaded, after Saipan. The Marianas mattered because they put Japan itself within range of the new American B-29 Superfortress bomber: from airfields on Saipan, Tinian and Guam, B-29s could reach Tokyo, and the capture of the Marianas was the first step in the bombing campaign against the Japanese home islands.

Saipan had fallen on 9 July 1944, after a bitter three-week battle that cost the Americans about 3,000 killed, and Tinian, just five kilometres south of Saipan across a narrow strait, was the obvious next target. The Japanese garrison on Tinian knew it was coming, and had spent months preparing defences, but it had received few reinforcements, and its commander had only about 9,000 men to hold an island 20 kilometres long.

Supply decided more of Battle of Tinian than any single order. Ammunition, fuel, food and water had to travel from depots far behind the lines, over roads that were shelled, mined or washed out, and every delay at the front was felt first in the supply columns. The side that kept its guns fed and its men fed could keep attacking; the side that could not was forced to stop, however good its plan. At Battle of Tinian, as in most battles of this period, the quartermasters and the drivers mattered as much as the generals, and the battle’s turning points can often be traced to a convoy that arrived — or did not arrive — in time.

3.2. The Opposing Plans

The American plan was drawn up by Major General Harry Schmidt, commander of V Amphibious Corps, and it was built around deception. The Japanese expected a landing at Tinian Town, the island’s main settlement in the south, where the beaches were wide and the defences strongest.

The Americans encouraged that belief with a feint: on the morning of the landing, the 2nd Marine Division staged a demonstration off Tinian Town, with landing craft circling and naval gunfire pounding the southern beaches, while the real landing force — the 4th Marine Division, followed by the 2nd — came ashore on two narrow beaches, White 1 and White 2, on the north-west coast near the village of Ushi.

The beaches were only about 60 and 150 metres wide, and the Japanese had left them lightly defended, believing that no invader would try to land there.

Neither side at Battle of Tinian knew as much about the enemy as its commanders pretended. Reports were late, contradictory or simply wrong: prisoners exaggerated, scouts saw only a fragment of the front, and aerial photographs showed positions that had already been abandoned. Commanders filled the gaps with assumptions, and those assumptions decided battles. The history of Battle of Tinian is full of such judgements — an enemy division believed to be elsewhere, a flank thought secure, a strength underestimated by half — and the side whose assumptions were closest to the truth usually won, not because its generals were cleverer, but because its information was better.

3.3. The Eve of Battle

The lessons of Saipan shaped every part of the plan. At Saipan, the Americans had landed on wide beaches in daylight and fought their way inland against a strong defence; at Tinian, they landed at night in places the enemy had neglected, and they brought their artillery ashore early, so that the infantry would never be without fire support.

The naval bombardment was heavier and better aimed than at Saipan, and the Marines had practised the landing on the beaches of Saipan itself. The operation was also smaller and simpler than Saipan: a single island, a single enemy regiment as its core, and a clear objective — the airfields, especially the flat ground around Ushi Point, where the Americans planned to build the B-29 base.

Orders at Battle of Tinian travelled slowly and unreliably. Field telephones depended on wires that shellfire cut within minutes; radios were heavy, short-ranged and easily intercepted; and in the end much depended on runners — men who carried written orders across open ground under fire, and who sometimes never arrived. A battalion could fight for hours without knowing what its neighbours were doing, and a division could learn of a breakthrough only when the enemy appeared in its rear. The battle therefore has to be understood as a dozen small battles fought in partial ignorance of each other, held together by a command system that was always one step behind events.

3.3.1. The Wider War

The wider war shaped everything that happened at Battle of Tinian. By the time the fighting began, the conflict had already lasted for years, and both sides had learned hard lessons about supply, firepower and morale. Commanders on both sides knew that a single battle rarely decided a war, but that battles like this one decided whether armies could move, eat and fight the next week.

For the men who fought here, the strategic arguments debated in headquarters meant very little beside the next hill, the next street or the next stretch of water. What mattered was whether the artillery was in range, whether the rations arrived, and whether the unit on the flank held its ground.

The records of Battle of Tinian therefore have to be read on two levels at once: as a chapter in a much larger war, and as a human experience of fear, exhaustion and endurance that no headquarters map can capture.

4. Opposing Forces

4.1. The Attacking Force

The American landing force was two Marine divisions of V Amphibious Corps, under Major General Harry Schmidt. The 4th Marine Division, commanded by Major General Clifton Cates, was to land first on the White beaches, and the 2nd Marine Division, under Major General Thomas Watson, was to follow and land on the same beaches.

Together the two divisions numbered about 30,000 men, supported by the guns of battleships, cruisers and destroyers offshore, by carrier aircraft, and by the artillery of the divisions themselves, which was landed early and in strength. The Marines were veterans by 1944: the 2nd Division had fought at Tarawa and Saipan, and the 4th at Kwajalein and Saipan, and they brought with them the amphibious tractors, tanks and engineers that had become the standard tools of Pacific island fighting.

The Japanese garrison was built around the 50th Infantry Regiment, under Colonel Kiyochi Ogata, together with naval troops under Captain Goichi Oya and a small number of artillery and engineers. In total the Japanese had about 9,000 men on Tinian, of whom perhaps 4,000 were combat troops of the regiment.

Ogata had prepared strong defences around Tinian Town in the south, with pillboxes, trenches and artillery, and he had fortified the high ground in the centre of the island, Mount Lasso, which commanded the airfields. But his forces were thinly spread across an island 20 kilometres long, his artillery was limited to a handful of guns, and he had no air support and no hope of reinforcement once the American fleet arrived.

His plan was to hold the beaches and then to fight a delaying action in the hills, and he expected the main attack to come in the south.

The ground at Battle of Tinian rewarded the side that studied it. A ridge, a river, a wood or a ruined village could be worth a battalion, and commanders who had walked the ground — or who listened to the men who had — gained advantages that no map could give. The fighting followed the ground: attacks went where the ground allowed them, defences were built where the ground was strong, and the deadliest places in the battle were the places where the ground gave one side a clear field of fire and the other no cover at all. To read the battle without the map is to miss half of it.

4.2. The Defenders and Their Methods

The imbalance was overwhelming, and Ogata knew it. His only hope was that the Americans would land where he expected them, on the southern beaches, and that his defences there would bleed them as the defences of Tarawa and Saipan had bled the Marines.

The American deception denied him that hope: by landing in the north-west, the Marines came ashore where the Japanese were weakest, and they were able to bring their artillery and tanks ashore before the Japanese could react. The battle of Tinian was therefore decided, in large part, before the first Marine set foot on the beach.

The fighting that followed was still dangerous — the Japanese fought hard in the caves and hills of the island’s interior — but the outcome was never in doubt after the first day.

The weapons used at Battle of Tinian shaped the fighting in ways that the men who carried them understood better than their generals. A rifle that jammed in mud, a machine gun that could sweep a street, a tank that could not climb a slope, an artillery piece that could be heard but not seen — each weapon had its range, its rate of fire and its weakness, and battles were won by the side that matched its weapons to the ground. The technical details matter: the calibre of a gun, the thickness of a tank’s armour, the range of a radio. They are not footnotes to the battle; they are the reason the battle took the shape it did.

4.2.1. Guns, Engineers and Supply

Beyond the divisions listed in the table, the battle was decided by the less visible arms: the artillery that fired the preparatory bombardments, the engineers who cleared mines and built bridges, the signals units that kept commanders in touch with their forward troops, and the supply columns that brought forward ammunition, fuel, food and water.

At Battle of Tinian, as in most battles of this period, the side that could keep its guns supplied and its wounded evacuated had a decisive advantage, and the side whose communications broke down first usually lost the initiative. Air power mattered too, though not always in the way planners hoped: aircraft could strike a strongpoint or a column on the road, but they could not hold ground, and bad weather could ground them for days at a time.

The balance of forces was therefore never simply a count of men and tanks; it was a balance of systems, and the system that broke first decided the outcome.

5. The Battle

5.1. The Opening Moves

The landing began before dawn on 24 July 1944. Under cover of darkness, the 4th Marine Division came ashore on White Beach 1 and White Beach 2, two narrow strips of sand on the north-west coast that the Japanese had left almost undefended. The first waves met little resistance: a few machine guns, a few mines, and then the beaches were secure.

By mid-morning, the Marines had landed their artillery and tanks, and the 2nd Marine Division began to come ashore behind them. The feint at Tinian Town had worked perfectly: the Japanese kept their forces in the south, waiting for a landing that never came, while the Americans built up a force of two divisions on the northern beaches.

By the end of the first day, about 15,000 Marines were ashore, and the Japanese had lost their chance to throw the landing back into the sea.

Morale at Battle of Tinian was not a slogan but a physical fact. Men who had eaten, slept and believed in their officers fought differently from men who were hungry, exhausted and leaderless, and the same unit could be brave on one day and broken on the next.

Fear was universal — veterans admitted it freely — and what kept men fighting was rarely hatred of the enemy but loyalty to the men beside them, the shame of running, and the simple habit of obeying orders. The battle’s histories often describe morale as if it were a quality of armies; at Battle of Tinian it was a quality of small groups of men, and it could collapse in a single afternoon.

5.2. The Main Assault

On 25 July the Marines began their advance south, towards the airfields and the high ground of Mount Lasso. The 4th Division advanced along the western coast and the 2nd Division along the eastern side of the island, and the two divisions moved in a pincer that squeezed the Japanese towards the south.

The fighting was sharpest around Mount Lasso, where the Japanese had fortified the ridges and caves, and where American tanks and artillery had to reduce one position at a time. The Japanese fought in small groups, emerging from caves to attack at night, and the Marines answered with flame-throwers, demolition charges and tanks firing into the cave mouths.

The advance was slow and costly in places, but it never stopped, and by 28 July the Marines had taken Mount Lasso and the airfields around Ushi Point.

The wounded of Battle of Tinian depended on a chain of care that began with the man beside them. Stretcher-bearers carried them from the firing line, often under fire; aid stations, in a cellar, a ditch or a ruined house, gave them morphine and bandages; and if the roads allowed, they were evacuated to field hospitals and then further back. Many died of wounds that a modern hospital would have treated, and many lived because a comrade reached them in time. The medical story of the battle is inseparable from its casualty figures: the difference between killed and wounded, and between wounded and dead of wounds, is a measure of how well that chain worked.

5.3. The Crisis

The last days of the battle were fought in the south of the island, around Tinian Town and the cliffs of the southern coast. The Japanese, driven back from the north, made their stand in the caves and ravines of the southern hills, and the Marines had to clear them one by one.

On the night of 30-31 July, the Japanese launched a final counterattack, a banzai charge against the 2nd Marine Division’s lines, and were cut down by artillery and machine-gun fire. On 1 August, the remaining Japanese forces were driven into the cliffs at the southern tip of the island, and organised resistance ended. The battle had lasted eight days.

The Americans had lost 328 killed and 1,571 wounded; the Japanese had lost about 8,000 killed, and about 250 were taken prisoner.

Civilians were caught in Battle of Tinian in ways that the military histories often pass over. Farmers, shopkeepers, children and the old found their villages turned into battlefields, their houses into strongpoints, their fields into minefields. Some fled, some hid in cellars, and some were killed by shells fired at targets they could not see. Their losses are the hardest to count, because no army kept their names, and their suffering is the part of the battle that has no memorial. Any honest account of Battle of Tinian must remember that the battle was fought not on empty ground but in places where people lived, and that those people paid for it.

5.3.1. The Soldier’s Battle

For the soldiers, the battle was experienced in fragments: a long march or a cramped landing craft, a sudden burst of fire, hours of waiting under shelling, a short rush across open ground, and then the work of digging in again.

Orders from above arrived late or not at all, and junior officers and sergeants made the decisions that mattered, often with only a sketchy idea of what was happening a kilometre away. Communications were fragile — field telephones cut by shellfire, radios that failed in wet weather, runners who never arrived — and the picture in each headquarters was always hours behind the fighting.

That is why the history of Battle of Tinian is written from many small accounts: a company diary, a pilot’s report, a surgeon’s notes, a prisoner’s interrogation. No single source sees the whole battle, and the historian’s task is to fit the fragments together without inventing the missing pieces.

6. Turning Point

6.1. The Decisive Moment

The turning point of the battle was the landing itself, and specifically the choice of the White beaches. By landing where the Japanese were weakest, the Americans avoided the bloody frontal assault that the Japanese had prepared for at Tinian Town, and they gained a secure beachhead on the first day from which the whole island could be taken.

The deception — the feint at Tinian Town, the naval bombardment of the southern beaches, the landing craft circling offshore — was the decisive act of the battle, and it was planned by officers who had studied the failures at Tarawa and Saipan and were determined not to repeat them.

The Japanese, once they realised the real landing was in the north-west, could not shift their forces fast enough to contest it, and the battle was effectively decided before the second day.

The sources for Battle of Tinian are uneven, and the historian must weigh them carefully. Official histories were written to justify decisions; unit diaries were written in haste and in the dark; memoirs were written years later, when memory had softened or sharpened; and the records of the losing side were often destroyed. Numbers differ between sources, sometimes widely, and the figures in this article are given as ranges for that reason. Where sources disagree, this article follows the most widely accepted modern scholarship, and says so when the evidence is genuinely uncertain.

6.2. The Tactical Lesson

A second turning point was the capture of Mount Lasso and the airfields on 28 July. Mount Lasso was the key terrain of the island: from its summit, an observer could see the whole of Tinian, and its loss left the Japanese with no high ground from which to direct their defence.

The airfields were the prize the Americans had come for, and their capture meant that the battle’s strategic purpose was achieved even before organised resistance ended. The speed of the victory — eight days, against three weeks at Saipan — showed how far American amphibious warfare had come since 1942, and it set the pattern for the landings that followed at Iwo Jima and Okinawa, where the same combination of deception, firepower and speed would be attempted, with very different results.

The numbers at Battle of Tinian hide as much as they reveal. A division listed at full strength might have half its men sick, on leave or detached; a regiment that had fought for a week might be a shadow of itself; and the men counted as reinforcements might arrive without rifles, without training or without officers. Strength returns, the documents on which historians rely, are snapshots taken in the confusion of war, and they flatter the side that wrote them. The figures in this article should therefore be read as orders of magnitude — enough to show the balance of forces, but not precise enough to settle an argument to the last man.

6.2.1. How Turning Points Are Judged

Turning points are easy to name in hindsight and hard to recognise at the time, and Battle of Tinian is no exception. The commanders who fought here did not know which hour would decide the battle; they knew only that the next attack might break the enemy or break their own men.

Historians therefore judge a turning point not by a single dramatic moment but by what changed afterwards: whether supplies could still reach the front, whether reserves were still available, whether the losing side could still choose its next move. At Battle of Tinian, the change was visible in the orders that followed, in the ground that changed hands and stayed changed, and in the reports that grew more confident on one side and more desperate on the other.

That is the test this section applies: not the excitement of the moment, but the direction of everything that came after it, and the reasons why the initiative passed from one side to the other and did not come back.

7. Casualties and Losses

7.1. The Human Cost

The casualty figures for Tinian are unusually clear, because the battle was short and the American records are complete. The Americans lost 328 men killed and 1,571 wounded, a total of 1,899 casualties out of about 30,000 men landed. The 4th Marine Division, which landed first and did much of the fighting, suffered most of the losses.

The Japanese lost about 8,000 men killed, out of a garrison of about 9,000, and about 250 were taken prisoner. The disparity reflects the difference in firepower, the success of the American deception, and the Japanese practice of fighting to the death rather than surrendering.

The ratio of Japanese to American dead — about twenty-four to one — was one of the most lopsided of the Pacific War, and it was a measure of how completely the American plan had worked.

7.2. Counting the Losses

The civilian population of Tinian, about 15,000 people, most of them Japanese and Korean settlers and Chamorro islanders, suffered heavily in the battle. Many were killed in the bombardment and the fighting, and the survivors were interned in camps on Saipan for the rest of the war.

The exact number of civilian deaths is not known, and the figures are disputed, but several thousand civilians died on Tinian in July and August 1944. The island’s sugar cane fields, the mainstay of its economy, were destroyed, and the island was transformed by the Americans into a vast air base.

The civilian cost of Tinian is often forgotten beside the military story, but it was real, and it is part of the battle’s history.

| | United States | Japan |
|—|—|—|—|
| Killed | 328 / 328 | About 8,000 |
| Wounded | 1,571 / 1.571 | Few recorded |
| Prisoners | — | About 250 |
| Total | 1,899 / 1.899 | About 8,000-8,500 |

7.2.1. Wounds, Burial and Records

Behind every casualty figure lies a medical system under strain. Wounded men were carried from the firing line by stretcher-bearers, treated at aid stations, and evacuated — when the roads and the weather allowed — to field hospitals and then to base hospitals far behind the lines.

Many of the wounded at Battle of Tinian died not on the battlefield but of wounds, shock and infection in the hours and days that followed, and the difference between life and death often came down to how quickly a man could be reached and how far he had to travel.

The dead were buried where they fell or in temporary cemeteries, and their names were recorded as best the circumstances allowed; in the confusion of battle, some were listed as missing for months or years. That is one reason why the figures in the table above are given as ranges: they are the best that the surviving records allow, not a precise count, and different historians, working from different archives, will always reach slightly different totals.

8. Map and Geography

8.1. The Ground

Tinian is a small island in the Mariana archipelago, about 20 kilometres long and 8 kilometres wide, lying just five kilometres south of Saipan across the Saipan Channel. The island is a raised coral plateau, flat in the north, where the airfields were built, and hilly in the centre and south, where Mount Lasso, 178 metres high, commands the whole island.

The coastline is mostly cliffs, with only a few beaches, and the White beaches in the north-west were among the smallest and least inviting on the island — which is why the Japanese left them lightly defended. The island’s interior is broken by ravines and caves, formed in the coral limestone, and it was in those caves that the Japanese made their last stands.

8.2. Why the Ground Mattered

The geography of Tinian shaped the battle in two ways. First, the flat northern plateau made the island ideal for airfields: the Americans built North Field, with four parallel runways, and West Field, and Tinian became the largest air base in the Pacific, capable of launching the B-29 raids on Japan.

Second, the cliffs and caves of the southern hills made the last days of the battle a slow, grinding clearance, in which the Marines had to root out small groups of Japanese soldiers one cave at a time. The island’s small size — it could be crossed on foot in a day — meant that the battle was short, and that the Americans, once ashore, could bring their full weight to bear quickly.

Tinian’s geography, in short, made it both easy to take and immensely valuable once taken.

8.2.1. Weather and Season

Weather and season were as much a part of Battle of Tinian as any general’s plan. Rain turned roads to mud and grounded aircraft; cold froze the wounded where they lay and numbed the fingers of men trying to load their rifles; heat and dust choked engines and exhausted marching men.

Darkness, fog and smoke hid movement but also made it impossible to tell friend from foe, and more than one unit in this battle fired on its own side or marched into the wrong position because the ground looked different in the dark.

Commanders who understood the ground and the weather — who knew where the water would be, where the roads would hold, and how far a man could march in a day — had an advantage that no amount of firepower could replace.

The map of Battle of Tinian is therefore not only a record of where the fighting happened, but a reminder that geography and climate are actors in every battle, not merely its stage.

9. Outcome and Legacy

9.1. The Immediate Result

The capture of Tinian had consequences far beyond the island itself. North Field, completed in the months after the battle, became the base for the 509th Composite Group, and on 6 August 1945 the Enola Gay took off from Tinian to drop the first atomic bomb on Hiroshima; three days later, Bockscar took off from the same airfield to bomb Nagasaki. The island that the Marines had taken in eight days became the place from which the war was ended. The connection is not a matter of pride for everyone: the atomic bombings remain among the most debated acts of the war, and Tinian’s place in that story is part of the island’s legacy, for better and for worse.

9.2. The Longer Legacy

Militarily, Tinian became the model of a successful amphibious landing, studied in staff colleges as an example of what deception, preparation and firepower could achieve. The lessons of Tinian — land where the enemy is weak, bring your artillery ashore early, and do not repeat the mistakes of the last landing — were applied at Iwo Jima and Okinawa, though the Japanese, having learned their own lessons, no longer defended the beaches, and the battles that followed were far bloodier.

Today Tinian is a quiet island, its airfields overgrown, its population small. North Field is preserved as a historic site, and visitors can stand on the runway from which the Enola Gay took off, and on the beaches where the Marines landed in the dark on 24 July 1944.

9.2.1. How Historians Judge the Battle

Historians still argue about Battle of Tinian, and the argument is part of the battle’s legacy. Some stress the decisions of the commanders and the quality of the plans; others stress the numbers, the logistics and the weather; still others stress the experience of the ordinary soldiers, whose courage and endurance decided what the plans could achieve.

No single explanation is enough, and the honest historian leaves room for all of them. What is not in doubt is that the battle mattered to the people who fought it and to the families who waited for news of them, and that its effects — on the armies, on the civilians caught in the fighting, and on the course of the war — outlasted the last shot.

The memorials, cemeteries and museums that mark the battlefield today are not only places of remembrance; they are also a warning. They record what happened when diplomacy failed and armies were sent to settle what politicians could not, and they ask every visitor to remember the cost.

10. Commanders

10.1. The American Corps and Division Commanders

Major General Harry Schmidt (United States). Commander of V Amphibious Corps, which took Saipan and Tinian. Schmidt planned the Tinian landing, including the deception at Tinian Town and the choice of the White beaches, and he directed the corps through the battle. He later commanded V Amphibious Corps at Iwo Jima.

Major General Clifton Cates (United States). Commander of the 4th Marine Division, which landed first on Tinian. Cates, a veteran of the First World War, led his division through Kwajalein, Saipan and Tinian, and later became Commandant of the Marine Corps.

10.2. The Marine Division Commander and the Japanese Garrison Commander

Major General Thomas Watson (United States). Commander of the 2nd Marine Division, which followed the 4th ashore on Tinian and fought the battle for Mount Lasso and the southern hills. Watson had commanded the division at Saipan and led it through Tinian.

Colonel Kiyochi Ogata (Japan). Commander of the 50th Infantry Regiment and of the Japanese garrison on Tinian. Ogata prepared the island’s defences, expecting the main American landing at Tinian Town, and was killed in the fighting in the south of the island. His misreading of the American plan decided the battle.

10.3. The Japanese Defence

Captain Goichi Oya (Japan). Commander of the Japanese naval forces on Tinian. Oya’s troops fought alongside Ogata’s regiment in the defence of the island, and he was killed in the final fighting around Tinian Town.

Lieutenant General Yoshitsugu Saito (Japan). Commander of the Japanese forces on Saipan, whose defeat in July 1944 left Tinian isolated and without hope of reinforcement. Saito’s death on Saipan shaped the fate of Tinian, which was invaded two weeks later.

10.3.1. Command and Responsibility

Command at Battle of Tinian carried a weight that is hard to grasp from the safety of hindsight. The generals who ordered the attacks knew that their orders would kill men, including men they had served with for years, and they gave those orders anyway, because the alternative — inaction, retreat, delay — seemed worse.

Some of them were right and some were wrong, and history has judged them accordingly, but the judgement is rarely simple: a commander who was cautious at Battle of Tinian might have been reckless elsewhere, and a commander who won here might have done so by spending lives that a better plan would have saved. The biographies in this section should be read with that in mind.

These were not figures in a legend but professional soldiers, working with incomplete information, under political pressure, and with the lives of thousands of men in their hands. Their decisions — good and bad — are the reason the battle took the shape it did, and the reason it is still studied today.

11. Frequently Asked Questions

When was the Battle of Tinian fought?
From 24 July to 1 August 1944. Organised Japanese resistance ended on 1 August, though small groups of Japanese soldiers held out in the hills for months afterwards.

Why is Tinian famous?
Because North Field, the airfield the Americans built on Tinian, was the base from which the Enola Gay flew to bomb Hiroshima on 6 August 1945, and Bockscar flew to bomb Nagasaki on 9 August 1945.

How did the Marines land on Tinian?
By deception: they staged a feint at Tinian Town in the south, where the Japanese expected them, and landed instead on two narrow beaches, White 1 and White 2, in the north-west, which the Japanese had left almost undefended.

How many Americans died at Tinian?
328 killed and 1,571 wounded, a total of 1,899 casualties. It was one of the least costly major landings of the Pacific War for the Americans.

Who commanded the Japanese on Tinian?
Colonel Kiyochi Ogata, commander of the 50th Infantry Regiment, together with Captain Goichi Oya, commander of the naval forces. Both were killed in the battle.

Can you visit Tinian today?
Yes. North Field is preserved as a historic site, and visitors can see the runways, the atomic bomb loading pits, and the White beaches where the Marines landed. Tinian is a quiet island with a small population.
