How Al Schmid, a single machine gun, and sheer willpower helped save Guadalcanal
At 3:02 a.m. on August 21, 1942, the jungle along the Tenaru River on Guadalcanal vibrated with movement. In the darkness, hundreds of Japanese soldiers assembled for a decisive assault. Their objective was clear: overrun the American defenses, retake Henderson Field, and push the Allies out of the Solomon Islands.
On the west bank of the river, in a shallow, sandbagged pit camouflaged with palm fronds, Al Schmid crouched behind a Browning M1917A1 .30-caliber machine gun. He was 21 years old, had been on the island barely two weeks, and had never fired his weapon in combat. Before the war, he had been an apprentice steelworker in Philadelphia. Now, he was one of three Marines guarding one of the most important pieces of ground in the Pacific.
By dawn, Schmid would be blind. By night’s end, the Japanese attack would be shattered. And Henderson Field would still be in American hands.
Why Guadalcanal Mattered
Henderson Field was the strategic heart of Guadalcanal. Captured by U.S. Marines shortly after their landing on August 7, the half-finished airstrip was quickly made operational. From there, Marine and Navy aircraft could strike Japanese supply lines and shipping routes across the South Pacific.
If Henderson Field fell, Guadalcanal would fall. If Guadalcanal fell, the entire Allied defensive line in the Pacific would be endangered.
The Japanese understood this. Colonel Kiyonao Ichiki, commanding an elite infantry detachment, believed the Marines were inexperienced and demoralized. Confident in speed and spirit, he ordered an immediate nighttime assault across the Tenaru River.
He underestimated the men waiting on the far bank.
Three Marines in a Shallow Pit
Schmid’s machine-gun crew consisted of:
-
PFC Johnny Rivers, the primary gunner and the most experienced of the three
-
Corporal Leroy Diamond, assistant gunner and ammunition handler
-
Private Al Schmid, responsible for feeding belts and maintaining the water-cooled barrel
Fifty yards of open river and sandbar separated them from the attacking force. No trenches. No fallback position. If the Japanese crossed, the line would collapse.
At exactly 3:00 a.m., green flares arced into the sky—the signal to attack.
The First Waves
The first Japanese soldiers charged across the sandbar in tight formation, shouting and firing to draw premature fire. Rivers held his nerve, waited until the enemy reached the middle of the river, then opened up.
The Browning roared to life.
At nearly 450 rounds per minute, tracer fire ripped through the darkness. Men fell into the river. Others tripped over bodies and kept coming. Wave after wave advanced, and wave after wave was cut down in the shallow water.
For over half an hour, the gun ran continuously. Steam hissed from the water jacket as Schmid refilled it again and again. Ammunition belts vanished at a terrifying pace. The barrel glowed red.
Then disaster struck.
The Gun Falls Silent—For a Moment
A Japanese grenade exploded near a neighboring machine-gun position, silencing it completely. All enemy fire now focused on Schmid’s pit. Bullets shredded sandbags and coconut logs. Shrapnel flew. Diamond was hit in the arm, badly wounded but still conscious.
At 3:41 a.m., Rivers was struck repeatedly in the face and neck. He died instantly, his finger locked on the trigger. The Browning fired on for several seconds before Schmid shoved Rivers’ body aside and took his place.
He had never been trained as a gunner in combat.
He pressed the trigger anyway.
A Grenade in the Pit
Schmid fought on, firing until the gun was nearly melting. Japanese soldiers changed tactics, crawling low and throwing grenades. One of them landed inside the pit, beside Schmid’s knee.
The explosion tore into his face.
When the smoke cleared, Schmid could see nothing. Shrapnel had destroyed his left eye and severely damaged the right. Blood poured down his face. Pain came in blinding waves—then darkness.
The attack, however, had not stopped.
Fighting Blind
Diamond understood instantly what had happened. Despite his own wound and blood loss, he stayed conscious long enough to guide Schmid.
“Left.”
“Right.”
“Closer.”
“Fire.”
Schmid aimed the machine gun by voice alone.
Burning metal scorched his hands. The gun jammed repeatedly as overheated parts warped. Schmid cleared stoppages by touch, unable to see what he was doing. Diamond fed ammunition with one good arm, tapping Schmid’s shoulder when a belt ran dry.
For nearly two more hours, the blind Marine kept firing.
The Japanese pressed harder, believing the gun was weakening. Instead, they ran into a wall of steel guided by sound and determination. Bodies piled up on the sandbar. The river ran red.
Dawn and Defeat
As dawn approached, the attack finally faltered. The Japanese had lost hundreds of men. Colonel Ichiki’s detachment was destroyed as a fighting force. Survivors fled into the jungle. Ichiki himself would later take his own life.
Henderson Field was saved.
Medics found Schmid still seated behind the shattered Browning, blind, wounded, and waiting for the next attack that never came.
Aftermath and Legacy
Schmid lost one eye completely and retained only limited vision in the other. His military career ended, but his life did not.
He received the Navy Cross for extraordinary heroism. His story became the basis for the book Al Schmid, Marine and the film Pride of the Marines. He married his fiancée Ruth, raised a family, and lived quietly for decades, rarely speaking about that night.
When he died in 1982, he was buried at Arlington National Cemetery.
The official counts vary, but historians agree on the result:
-
Hundreds of Japanese casualties at the Tenaru
-
A shattered myth of Japanese invincibility
-
The first decisive American ground victory in the Pacific
Why This Night Still Matters
The Battle of the Tenaru was not won by technology or overwhelming force. It was won by:
-
Three Marines
-
One machine gun
-
And a refusal to quit, even after sight itself was taken away
Guadalcanal marked the turning point of the Pacific War. And on that turning point stood a blind Marine, firing by voice command, holding the line when the line could not fall.
Al Schmid did not fight for glory.
He fought because stopping meant defeat.
And because of that, history moved forward.
