June 3rd, 1942.

Aboard the aircraft carrier Akagi, Vice Admiral Tuichi Nagumo stood on the bridge as his flagship cut through the North Pacific swells.

Around him spread across miles of ocean, steamed the most powerful naval strike force ever assembled.

Four fleet carriers, two battleships, three cruisers, and a screen of destroyers.

Below decks, mechanics made final checks on hundreds of aircraft.

In the ready rooms, pilots reviewed their attack plans for tomorrow’s strike against Midway Island.

Nagumo was 55 years old, a torpedo warfare specialist who had never particularly liked aviation.

Yet here he was commanding the Kido Bhai, the first airfleet that had struck Pearl Harbor 6 months earlier.

That attack had been flawless.

The Americans had been caught completely unprepared.

Japanese aircraft had destroyed or damaged eight battleships, killed thousands, and returned with minimal losses.

Since then, the Kido Bhutai had rampaged across the Pacific, striking at will from Darwin to Salon.

No one had been able to stop them.

Tomorrow would be different, only in that the target was smaller.

Midway was just an atoll, two tiny islands with an airfield.

Intelligence reported a few dozen American aircraft there, perhaps some patrol boats.

Nothing the Kido Bhutai couldn’t handle in an afternoon.

After neutralizing Midway’s defenses, they would occupy the atole.

That would extend Japan’s defensive perimeter, and more importantly, it would lure the remnants of the American Pacific Fleet into a decisive battle.

The Americans would have to respond to the threat to Midway.

When they did, Yamamoto’s battleships waiting to the west would destroy them.

At least that was the plan.

Nagumo had reservations he kept largely to himself.

400 m to the west aboard the battleship Yamato, Admiral Isuroku Yamamoto commanded the operation from a distance that troubled some of his staff.

Yamato was the largest battleship in the world, displacing over 60,000 tons, mounting 18-in guns that could hurl shells weighing more than a ton over 25 m.

But for all its power, Yamato was too slow to keep up with the carriers.

So Yamamoto directed the battle from far behind the striking force connected to Nagumo only by radio.

Yamamoto was 57, a Harvard educated officer who had spent years in America and understood American industrial power better than most of his colleagues.

He had opposed war with the United States, telling politicians that he could run wild for 6 months to a year, but after that, he had no confidence in victory.

Now, 6 months after Pearl Harbor, he was trying to force a decisive battle before American production overwhelmed Japan’s early gains.

The plan for Midway was complex, perhaps too complex.

Forces were divided across thousands of miles of ocean.

A diversionary attack on the Aleutian Islands to the north would draw American attention away.

The carriers would strike midway.

Then, when the American fleet responded, the battleships would close in for the kill.

It required precise timing, perfect coordination, and one critical assumption that the Americans would react exactly as predicted.

On the evening of June 3rd, Yamamoto staff reviewed the latest intelligence reports.

There was no indication that American carriers were anywhere near Midway.

Radio traffic analysis suggested they were still near Hawaii over a thousand miles away.

Even if they sorted immediately upon learning of the midway attack, they couldn’t arrive in time to interfere.

The operation would be over before they got there.

Commander Yasuji Watanab Yamamoto’s operations officer had helped plan every detail.

He knew the American carriers were the real target.

Midway itself meant nothing.

The atal was bait and everything depended on the Americans taking it.

In his post-war account, Watanab recalled the confidence that permeated Yamato’s operations room that evening.

“We believed we had achieved complete surprise,” he said.

“Our intelligence indicated the American carriers were not in the area.

We expected to strike Midway, draw out their fleet, and destroy it.

” What Watanabe and Yamamoto didn’t know was that American codereakers had been reading Japanese naval communications for weeks.

They knew about Midway.

They knew approximately when the attack would come, and three American carriers, Enterprise, Hornet, and Yorktown were already at sea, positioned northeast of Midway, waiting an ambush.

Aboard a Kagi.

That evening, the mood was almost festive.

Officers gathered in the wardroom discussing the upcoming operation over dinner.

Commander Minoru Jender, the brilliant air operations officer who had helped plan the Pearl Harbor attack, should have been among them.

Instead, he lay in his cabin, burning with fever.

Pneumonia had struck him days earlier.

The ship’s doctor had confined him to bed, warning that his condition was serious.

Gender refused to stay down.

At 37, he was one of the most innovative aviation tacticians in the Imperial Navy.

He had fought in China, developed new divebombing techniques, and had been instrumental in planning every major carrier operation since the war began.

The idea of missing the battle was unbearable.

According to his own later account, he told the doctor, “I will not stay in bed while my carriers go into action.

If I’m going to die, I’ll die at my post.

The doctor reluctantly agreed to let him work, provided he rest as much as possible.

Gender’s illness was more than a personal hardship.

His tactical judgment had been crucial in previous operations.

Now, at a moment when sharp thinking might matter most, one of Nagumo’s key advisers was operating at diminished capacity.

Rear Admiral Tamman Yamaguchi commanded the second carrier division here and Soryu, the two smaller carriers in Nagumo’s force.

At 49, Yamaguchi was considered one of the Navy’s rising stars.

He had attended Princeton, understood Americans, and had a reputation for aggressive tactics.

Unlike Nagumo, Yamaguchi was an aviation enthusiast who trusted his pilots and believed in taking calculated risks.

That evening, Yamaguchi met with his staff aboard Hiru to review the next day’s operations.

His chief of staff later recalled that Yamaguchi expressed concern about the divided nature of the plan.

The carriers would strike midway at dawn, but they would have to hold back a reserve in case American ships appeared.

This split focus troubled him.

In carrier warfare, he believed you concentrated everything on the primary target.

Dividing your strength invited disaster, but Yamaguchi kept his concerns professional.

Orders were orders.

His carriers would launch their assigned aircraft on schedule.

If American ships appeared, they would deal with them.

He had confidence in his air groups and his captains.

Hiru’s air group commander, Lieutenant Joi Tomaga, was one of the best in the fleet.

Rear Admiral Runoske Kusaka served as Nagumo’s chief of staff, the admiral’s closest adviser.

At 51, Kusaka was methodical, cautious, and deeply loyal to Nagumo.

He understood his commander’s limitations with aviation and tried to compensate by ensuring staff work was thorough.

That evening, he reviewed the operation orders one more time, checking details, confirming that every unit understood its role.

Kusaka later wrote about the atmosphere on Akagi’s bridge that night.

There was confidence, perhaps too much confidence, he recalled.

We had won every engagement since the war began.

Our pilots were veterans.

Our ships were undamaged.

We saw no reason why Midway should be different from our previous operations.

But Kusaka also noted a nagging concern that he shared with Nagumo in private.

The operation required them to accomplish two potentially conflicting missions.

Neutralize Midways air base and be ready to engage American warships if they appeared.

If American carriers were nearby, which seemed unlikely but possible, the Kido Bhai might find itself caught between two objectives at the worst possible moment.

Nagumo listened, but didn’t share Kusaka’s worry publicly.

The admiral had learned to trust his staff, particularly Gender, whose tactical instincts had proven sound.

With Gender ill, more responsibility fell on Kusaka’s shoulders.

As night fell on June 3rd, the Kido Bhai maintained radio silence and pressed eastward through darkness.

The sea was rough with low clouds and occasional rain squalls.

Weather reports suggested conditions would improve by morning, good enough for flight operations, but with some cloud cover that might help conceal the carriers from American patrol planes.

In the ready rooms, pilots attended final briefings.

The plan called for a strike of over a 100 aircraft to hit midway at dawn, dive bombers, torpedo planes, and fighters.

Their targets were the airfield, fuel dumps, and any aircraft on the ground.

It would be a powerful blow, but not overwhelming.

Nagumo was holding back a substantial reserve, nearly half his aircraft in case enemy ships appeared.

Lieutenant Jochi Tomaga, who would lead the strike, was 35 years old and had flown combat missions since the war’s beginning.

He had led attacks on Darwin and Son.

His pilots respected him for his skill and his willingness to lead from the front.

That evening he briefed his air group on the attack plan.

According to pilots who were present, Tomaga was calm and professional.

“We will destroy their airfield and return safely,” he told them.

“Expect anti-aircraft fire, but minimal fighter opposition.

The Americans at Midway are not prepared for what we’re bringing.

” What Tomaga didn’t know, what none of them knew, was that Midway’s radar had been recently upgraded.

The Americans would have warning of their approach, and three American carriers with over 200 aircraft were positioned to strike the Kido Boutai while its decks were cluttered with aircraft returning from midway.

Aboard Yamato far to the west, Yamamoto retired to his cabin around midnight.

His staff would wake him if anything significant developed.

He had done everything he could to ensure success.

The forces were in position.

The plan was sound.

American carriers were nowhere near the area.

By tomorrow evening, Midway would be in Japanese hands, and the American fleet would be steaming into a trap.

But Yamamoto was a poker player, and he understood that even the best hands could lose.

In a conversation with his senior staff officer that evening, he had mused about the Americans.

They are not stupid, he said, according to postwar accounts.

They will fight cleverly.

We must not underestimate them.

It was as close as the admiral came to expressing doubt.

The hours before dawn on June 4th were busy aboard the carriers.

Mechanics prepared aircraft, arming them with bombs for the midway strike.

Pilots ate breakfast, checked their gear, and gathered for final briefings.

The weather had improved as predicted.

Visibility was decent with scattered clouds at 3,000 ft.

At 0430, a kagi turned into the wind.

On the darkened flight deck, aircraft engines roared to life.

One by one, they thundered down the deck and lifted into the pre-dawn darkness.

Tomaga led them east toward midway, over a 100 aircraft in a formation that would have terrified any observer.

This was the Kido Bhai at full power.

The force that had humbled the American fleet at Pearl Harbor on Akagi’s bridge.

Nagumo watched the launch with satisfaction.

The operation was proceeding exactly on schedule.

Behind him, Kusaka coordinated with the other carriers.

Kaga, Hiru, and Soryu had also launched their strikes.

Now came the waiting period.

The aircraft would take about an hour to reach Midway, conduct their attack, and return.

During that time, the carriers would recover scout planes, maintain combat air patrol, and keep the reserve strike force ready.

That reserve was the key to the plan’s flexibility.

93 aircraft sat on the hanger decks, armed with torpedoes and armor-piercing bombs for use against ships.

If American carriers appeared, these aircraft could launch immediately.

If no ships appeared, they could be rearmed with land attack bombs and sent against Midway in a second strike.

Gender, despite his fever, had insisted on being on the bridge for the launch.

He stood near Nagumo, wrapped in a coat, watching the eastern horizon begin to lighten.

In his postwar writings, he described feeling uneasy, though he couldn’t articulate why.

Everything was going according to plan, he wrote, but I felt something was wrong.

Perhaps it was the fever affecting my judgment.

At 0530, reconnaissance aircraft launched from the cruisers and battleships.

These float planes would search the ocean to the east and south looking for American ships.

It was standard procedure, though no one expected them to find anything.

The searches had been delayed slightly by catapult problems on the cruiser tone, but this seemed a minor issue.

The scout would cover its assigned sector, just a bit behind schedule.

At 0700 hours, the first reports came back from the Midway Strike Force.

Tomaga radioed enemy fighters rising to intercept.

The Americans were reacting, but this was expected.

Minutes later, another message.

Encountering heavy anti-aircraft fire.

Still nothing alarming.

Midway’s defenses were more robust than intelligence had suggested, but nothing the strike force couldn’t handle.

Then at 0705, American aircraft from Midway appeared.

Obsolete torpedo bombers and dive bombers flying in uncoordinated attacks against the Kido Bhutai.

The carriers combat air patrol and anti-aircraft guns tore them apart.

The attacks were brave but futile.

Not a single American aircraft scored a hit.

Burning planes fell into the sea.

The few survivors limped back toward Midway.

On a Kagi’s bridge, the easy victory reinforced confidence.

These Americans were courageous, but poorly trained and equipped.

Their attacks were uncoordinated, almost suicidal.

If this was the best Midway could throw at them, the operation would be even easier than planned.

But the attacks had an effect no one on the Japanese side immediately recognized.

They forced the carriers to maneuver, breaking formation, disrupting the neat organization of the fleet, and they kept the combat air patrol busy at low altitude, shooting down attackers, burning fuel, unable to climb to higher altitude where they might spot approaching threats.

At 0728, a message arrived that changed everything.

The scout plane from the cruiser tone, the one that had launched late, reported, “Sight what appears to be 10 enemy surface ships bearing 010° distance 240 mi from Midway.

” On AGI’s bridge, the message created immediate tension.

Ships, American ships, northeast of the carriers, roughly where they shouldn’t be.

But what kind of ships? Cruisers, destroyers, or something more dangerous? Nagumo turned to Kusaka.

Find out what type of ships, he ordered.

The message was transmitted to the scout plane.

Now came an agonizing wait.

The scout needed time to close the distance, identify the ships, and report back.

Meanwhile, another message arrived from Tomaga, still over midway.

There is need for a second attack.

The first strike had hit the island hard but hadn’t completely neutralized its defenses.

The runway was damaged but still operational.

Hangers were burning but American aircraft were still flying.

To truly suppress Midway, another strike would be necessary.

Nagumo faced a decision.

He had 93 aircraft on his hanger decks, armed with torpedoes and armor-piercing bombs for use against ships.

But if those 10 ships the scout had spotted were just cruisers or destroyers, they weren’t worth a full strike.

Better to rearm those aircraft with land attack bombs, send them against Midway and finish the job Tomaga had started.

But if carriers were among those ships, launching a strike armed for land attack would be disastrous.

Torpedoes and armor-piercing bombs were essential for attacking carriers.

The decision hung on one question.

What type of ships had the scout found? At 0745, without waiting for clarification, Nagumo made his choice.

Prepare to rearm the reserve aircraft with land attack bombs, he ordered.

It was a reasonable decision based on available information.

Intelligence had consistently indicated no American carriers were in the area.

10 ships probably meant a cruiser force sent out from Pearl Harbor in response to the Midway attack.

They could be dealt with later.

Right now, finishing Midway was the priority.

Gender standing nearby was too ill to object forcefully.

Later, he would say he felt the decision was premature, that they should have waited for confirmation.

But in the moment, burning with fever, he didn’t press the point.

On the hangar decks below, ordinance crews began the laborious process of switching weapons.

Torpedoes had to be removed, taken back to the magazines, and replaced with land attack bombs.

It would take time, perhaps an hour, but once complete, Nagumo could launch a devastating second strike against Midway.

At 0800 hours, the first wave of aircraft began returning from Midway.

They had fought through heavy anti-aircraft fire, pressed home their attacks, and now needed to land.

Some were damaged.

Some were low on fuel.

The carriers turned into the wind to recover them.

This meant the reserve strike force, still being rearmed below decks, couldn’t launch until the Midway aircraft was safely aboard.

At 0809, the message everyone had been waiting for arrived from the scout plane.

Enemy ships are five cruisers and five destroyers.

Relief swept through Akagi’s bridge.

No carriers, just cruisers and destroyers.

Nagumo’s decision to rearm for a second Midway strike was vindicated.

Those ships could be dealt with later after Midway was thoroughly suppressed.

But at 8:20, another message arrived.

This one with very different implications.

Enemy force accompanied by what appears to be a carrier.

A carrier.

An American carrier 240 mi away with aircraft that could already be in the air heading toward the Kido Bhai.

The bridge erupted in controlled chaos.

Kusaka immediately grasped the situation.

We must launch against that carrier immediately, he told Nagumo.

But how? The decks were full of aircraft returning from midway.

Below, the reserve strike force was in the middle of rearming.

Torpedoes removed, land attack bombs not yet fully loaded.

The carriers couldn’t launch until the midway aircraft landed.

And once they landed, they would need to be struck below to clear the decks, and the reserve strike force would need to be brought up, which meant moving the Midway aircraft out of the way in the hangers.

It was a traffic jam.

A choreography problem that would take time to solve.

Time they might not have.

Yamaguchi commanding Hiru and Soryu sent a message to Nagumo.

Consider it advisable to launch attack force immediately.

Yamaguchi understood carrier warfare.

Speed was everything.

If an American carrier was out there, it might already be launching.

Every minute of delay increased the danger.

But Nagumo faced an impossible situation.

He couldn’t launch with the decks full.
