At a.m.
on the morning of August 15, 1943, First Lieutenant Kenneth Walsh observed his wingman fly apart over the sky above Wella Lawella.
In about 90 seconds he would either be dead or accomplish something that no American pilot before him had ever done.
Years old, flight hours in the Corsair, zero experience fighting 50 Japanese fighters.
Alone.
The Imperial Japanese Navy had sent every available Zero from Rabaul.
50 Mitsubishi A6M fighters, 50 of the most agile aircraft in the Pacific, 50 pilots with an average of 800 combat hours of experience.
Walsh escorted a bomber squadron.
Standard mission, until the Zeros crashed out of the clouds at 22,000 feet .
His squadron leader was hit by a 20 mm grenade directly through the cockpit, dead before he could warn anyone.
His wingman broke formation and dived.
Two others turned around and went home.
That left Walsh alone.
Foot height, 50 Zeros heading towards the bomber formation below.

The American doctrine was crystal clear.
When outnumbered by more than three to one, evade, flee, and survive.
Losing a pilot was acceptable.
Losing a pilot and an entire bomber formation was catastrophic.
Walsh could see the bombers.
Twelve TBF Avengers, each loaded with torpedoes, each with a three-person crew.
36 American lives, dependent on the hunting companions they no longer had.
The Zeros closed the gap.
Walsh had maybe 10 seconds to decide.
Follow the doctrine and flee, or stay and die trying to save 36 men he had never met.

Part 1: The mechanic from Brooklyn.
Kenneth Walsh had been a mechanic before the war .
Brooklyn, New York.
Born in 1916 as the son of Irish immigrants.
His father died when Waltsh was young.
Industrial accident.
A cranial rupture; three men died, including his father.
Wall left school at 14 and began working in his uncle’s workshop, Patrick Walsh and Sons Automotive.
The workshop specialized in difficult repairs, engines that other shops could not repair.
Walsh spent six years learning how machines work.
Not from books, but by taking things apart and putting them back together.
His uncle taught him to think about systems .
Each part influences every other part.
Everything is connected.
Until then, Walsh was the best diagnostic mechanic in Brooklyn.
He earned $42 per week.
Enough to support his mother.
Enough to perhaps one day consider having your own workshop.
Then came Pearl Harbor.
Wallsh reported on December 8, 1941.
He was 25 years old.
He told the recruiter he wanted to repair airplanes.
The recruiter looked at his test results.
Exceptional mechanical talent.
The recruiter said the Marines didn’t need a mechanic.
They needed pilots.
Walsh initially hated flying .
The Corser was a beast.
F4U gullwing fighter.
She had a reputation that terrorized flight students .
They called her the Eliminator, the Witwin Maker.
Between February and August 1943, the Navy lost 76 corsairs in training accidents.
54 pilots killed, not in combat, during training.
The problem was the engine.
The Prat and Whitney Air 2800 produced 2000 hp.
This force generated torque.
massive rotational force that caused the aircraft to roll to the left during takeoff.
At low speeds, the ailerons did not have enough airflow to counteract this torque.
The plane wanted to roll to the left.
If compensation wasn’t perfect, the left wing would fall off.
The plane would flip over.
You would die in a fireball.
Most pilots fought against the Corsa’s torque, jerking the control stick to the right during takeoff , trying to force the aircraft , gripping the stick so tightly that their hands cramped up.
This worked until fatigue set in, until attention waned and torque took over.
Walsh’s first instructor was Captain Robert Fraser.
Fraser flew 32 combat missions, scoring six kills.
He said something to Walsh during his third training flight that changed everything.
Walsh practiced evasive maneuvers, fighting against the aircraft.
Every time he added power, the Corser wanted to roll to the left.
Walsh countered.
The plane rolled to the right, back and forth.
never stable.
Fraser’s voice came through the intercom.
Walsh.
You are fighting against a force you cannot defeat.
You’re trying to compensate for 2000 horsepower with muscle power.
That’s not how you fly this plane.
Fraser explained, “The plane wants to roll to the left.
Let it roll to the left.
Just control how much and when.
The torque is constant.
If the power is constant, it’s predictable.
So you set your controls before you add power.
Trim the rudder to the right.
Then, when you add power, the plane is already compensated.
The force is balanced.
You’re not fighting, you’re managing.” Walsh had learned something similar working on car engines.
His uncle had said that when an engine produces torque, it affects the entire system.
You ca n’t isolate the forces.
You have to consider them everywhere .
Walsh suddenly understood that the Corser was a system.
The engine produced torque.
The torque affected everything.
You couldn’t fight the torque in isolation.
You had to manage the entire system.
He set his controls to counteract the torque .
Then he gently added power.
The wings remained level.
No fighting, just balance.
Fraser noticed immediately.
His voice was impressed.
“What did you just do?” Walsh explained his thinking, the system, the torque, the compensation.
Fraser said, “Keep doing whatever you’ve just figured out, keep doing it .” Walsh applied this understanding to Elis.
States, landings, aerobatics, combat maneuvers.
He wasn’t fighting the Corser.
He was working with it.
The technique worked.
By the time Walsh arrived in the Pacific in May 1943, he had logged hours in Corsa without a single incident.
His squadron commander called Walsh’s flying mechanically perfect.
Walsh took it as confirmation that thinking like a mechanic was making him a better pilot .
Part 2: The Impossible Fight.
Walsh had engaged Zeros before.
Brief encounters, two-on-two dogfights.
His first kill had come on June 23 over Rendova.
A Zero had attacked from above.
Walsh had dived, built up speed, then pulled up, converted speed to altitude, and climbed back over the Zero.
The Japanese pilot tried to follow, But its engine couldn’t maintain the climb angle .
The Zero dropped, stalled.
Walsh dove toward him, fired.
The Zero exploded, proving energy management worked in combat , but 50 against one—no one trained for that.
No one had ever survived that.
The Zero could outmaneuver the Corsair at any speed below 300 mph , and could climb faster below 15,000 feet.
The Japanese aircraft was designed for maneuverability.
The Corsair was designed differently, built for speed and firepower.
In a dogfight against a Zero, the Corsair would lose every time.
American doctrine recognized this reality.
Never turn with a Zero , use speed, use altitude, hit and run.
But Walsh was alone with 50 Zeros.
Following the doctrine meant letting 36 Americans die .
If you want to know how Walsh survived, like and subscribe now.
These forgotten heroes deserve to be remembered.
The Corsair had the advantage in firepower.
6.50 50 caliber machine guns, 4,800 rounds per minute, 80 rounds per second.
Walsh could dump more lead on a target in 3 seconds than a Zero could fire in 30.
But you had to hit the target, and hitting 50 targets , all capable of outmaneuvering you , was impossible.
Unless you stopped trying to hit them and made them hit each other .
Walsh had 90 seconds to translate a mechanical understanding of torque into a tactical innovation .
The first Zero came up from 11 o’clock.
Dive attack, standard Japanese tactic.
Walsh saw it coming and did something against all instinct.
He turned toward the Zero Zoo.
No defensive turn, just a gentle bank toward the threat.
20 degrees bank, nose slightly up.
The Zero pilot saw Walsh turning toward him, probably thought Walsh was going for a head-on , but Walsh didn’t .
At 400 yards, Walsh rolled hard.
Right .
Full aileron, full rudder.
The Corser snapped 90 degrees in under two seconds.
Walsh pulled hard.
The nose rose.
The plane began to climb.
The Zero tried to follow, but the Zero pilot had committed to his dive, built up speed.
At that speed, the Zero couldn’t intercept.
Its maneuverability advantage vanished.
Walsh climbed through the Zero’s flight path.
He wasn’t trying to steer around the Zero.
He placed his plane in a position where the Zero would have to fly through his gunfire.
Three-dimensional chess, not dogfighting, geometry.
Walsh leveled off at the top of his climb.
The Zero was below him.
Walsh rolled onto its back, pulled back, came down from above.
The Zero pilot saw Walsh coming, tried to turn.
Too late.
Walsh fired.
A three-second salvo.
The Zero’s right wing exploded.
The fuel tank ruptured.
The plane rolled onto its back, plummeting toward the ocean.
Walsh didn’t watch it crash; he did n’t have time.
Four More Zeros swarmed his position.
He did the same, turned toward them, rolled, climbed, using the Corser’s power.
The second Zero didn’t learn from the first, dived too quickly.
Walsh climbed through its flight path, fired, and hit it in the engine cowling.
The Zero’s propeller stopped, the third and fourth Zeros separated, coming from opposite directions.
Pincer attack except for Walsh, who didn’t turn toward either of them.
He climbed steeply.
The Corsir’s R2800 engine produced 2000 hp.
The Zero’s Sakai engine produced 1150.
Walsh’s plane could outrun both Zeros .
Walsh pulled vertically, full power.
The Corsir was up on its tail.
The two Zeros tried to follow, but they couldn’t maintain the climb angle .
Their engines didn’t have the power.
Walsh reached 5000 feet above him, rolled onto its back, and dived.
The Corsir accelerated, falling at over 400 mph.
The Zero pilot saw He came, tried to dive.
Walsh fired from 400 yards.
The Zero rolled to the left, far away, smoking.
Three kills in 90 seconds.
Part 3.
The victory.
The Zero pilots were beginning to understand.
Walsh wasn’t trying to corner with him .
He was flying a completely different fight, using altitude, speed, the Corser’s power-to-weight advantage.
The next wave came from Walsh at 6 o’clock.
Six in line.
They were slamming into his tail.
Walsh did something crazy.
He throttled back his engine.
The Corser slowed dramatically.
The six Zeros were plummeting at four miles per hour.
They could n’t slow down that fast.
They were overtaking.
All six flew past Walsh , ending up in front of him instead of behind him.
Walsh pushed his throttle forward.
The R800 roared.
The Corser accelerated.
Walsh picked the last Zero and fired.
The Zero exploded; the other five Zeros scattered.
They had just He learned that it wasn’t safe to attack Walsh from behind.
The Japanese were getting frustrated.
Walsh could hear it on their radio frequencies.
They were angry, confused.
Walsh did n’t care.
He cared about making them focus on him.
Not the bombers.
The next attack came from several directions simultaneously.
Eight Zeros from above, six from the sides, four from below.
Eighteen fighters converged at once.
Walsh flew straight into the largest threat group.
He picked the eight Zeros diving from above, turned toward them, and climbed at full power.
At seven yards, Walsh opened fire, firing bullets into the formation.
The lead Zero took hits and pulled away.
The second Zero twitched and broke to the left.
The formation scattered.
Walsh had disrupted an attack of eight aircraft with a three-second salvo .
He taxied and dipped toward the flanks.
Same tactic.
They scattered.
In 30 seconds, Walsh had a coordinated An attack by 17 planes broke loose.
Walsh kept fighting, kept climbing, kept forcing the Zeros to respond to him.
At a.m., Walsh’s fuel level reached a critical point.
15 minutes of fighting.
Then he heard the radio call: Bombers leaving target area.
Thanks for the cover, Marines.
The Avengers had made their attack.
All 12 planes, all 36 crew members, were on their way home because Walsh had kept the Zeros busy for 15 minutes .
Walsh looked around.
There were 38 Zeros in the area.
He had killed four, confirmed, but more importantly, he had saved 36 Americans and proven something no one thought possible: A Corser could fight 50 Zeros and survive.
Not by being a better pilot, by being a better engineer.

Walsh turned home.
The Zeros didn’t follow.
Walsh landed at a.m.
After takeoff.
His Corser had seven holes.
None had hit anything critical.
On November 28, 1943, Walsh was awarded the Medal of Honor.
The citation mentioned his four confirmed kills.
It did n’t mention the engineering.
It did n’t mention that he had been thinking about torque and energy management while Zeros were firing at him.
But the pilots knew his true achievement was proving that you can survive impossible odds if you stop fighting the way everyone else is fighting and start thinking about physics .
Kenneth Walsh died on March 30, 1998.
He was 81 years old.
His funeral drew over two naval aviators.
Men who had flown with Walsh.
Men who had learned his techniques and survived .
That’s how innovation happens in combat .
Not through official doctrines, but through someone who sees the problem differently.
And now you know his name.
