SARATOGA SPRINGS, N.Y. -- He was 26 years old, 5-foot-4, weighed 130 pounds and came from Albany, New York.

And on the night of May 15, 1918, Pvt. Henry Johnson, a member of the all-black 369th Infantry Regiment, found himself fighting for his life against 20 German Soldiers out in front of his unit's trench line.

He fired the three rounds in his French-made rifle, tossed all his hand grenades and then grabbed his Army-issue bolo knife and started stabbing. He buried the knife in the head of one attacker and then disemboweled another German soldier.

"Each slash meant something, believe me," Johnson said later. "There wasn't anything so fine about it," he said. "Just fought for my life. A rabbit would have done that."

By the time what a reporter called "The Battle of Henry Johnson" was over, Johnson had been wounded 21 times and become the first American hero of World War I.

Johnson's actions during the night of May 15, 1918 brought attention to the African American Doughboys of the unit, the New York National Guard's former 15th Infantry, redesignated the 369th for wartime service.

The 369th Infantry, detached under French command, arrived on the front line trenches in the Champagne region on April 15, 1918.

They were relieved to be free of supply and service tasks of past months and ready to join the fight, now under the command of the French Fourth Army.

The American Expeditionary Forces detached the all-black regiment to bolster an ally and preserve racial segregation in the American command.

The French were less concerned about racial inequality, and welcomed the African American regiment that would earn its nickname as the Hellfighters from Harlem.

The regiment's first battle would otherwise be a footnote in WWI history, fought by only two Soldiers, were it not for the scrutiny the all-black regiment faced at the time.

After weeks of combat patrols, raids and artillery barrages, Pvts. Henry Johnson, 26, from Albany, N.Y., and his buddy Needham Roberts, 17, of Trenton N.J., from the regiment's 1st Battalion, Company C, stood watch near a bridge over the Aisne River at Bois d'Hauzy during the night of May 15.

An enemy patrol with an estimated 20-24 troops was determined to eliminate the outpost and bring prisoners back to learn about the all-black American force.

Around two in the morning, shots rang out and the sounds of wire cutters alerted the two American Soldiers. Johnson, opening a box of grenades, told Roberts to run back and alert the main line of defense. But at that moment the first enemy grenades landed in their position.

Johnson stalled the German patrol with grenades of his own, as Roberts was struck down with shrapnel wounds to his arm and hip. When out of grenades, he took up his French rifle.

"The Labelle rifle carries a magazine clip of but three cartridges,' noted Arthur Little, the 1st Battalion Commander in his 1936 book "From Harlem to the Rhine."

"Johnson fired his three shots - the last one almost muzzle to breast of the Boche (German) bearing down upon him. As the German fell, a comrade jumped over his body, pistol in hand, to avenge his death. There was no time for reloading. Johnson swung his rifle round his head, and brought it down with a thrown blow upon the head of the German. The German went down, crying, in perfectly good Bowery English, "The little black (so and so) has got me!"

As Johnson looked over to assist Roberts, he saw two Germans lift him up to carry him off towards the German lines.

"Our men were unanimous in the opinion that death was to be preferred to a German prison," Little wrote. "But Johnson was of the opinion that victory was to be preferred to either."

Johnson reached for his Army-issued bolo knife and charged. His aggressiveness took the Germans by surprise.

"As Johnson sprang, he unsheathed his bolo knife, and as his knees landed upon the shoulders of that ill-fated Boche, the blade of the knife was buried to the hilt through the crown of the German's head."

The Army adopted the bolo knife from its experience in the Philippine Insurrection of 1899. The big knife, used by Philippine insurgents, was heavily weighted along the back of its curved blade, and was devastating for close quarter combat.

Turning to the face the rest of the German patrol, Johnson was struck by a bullet from an automatic pistol, but continued to lunge forward, stabbing and slashing at the enemy.

The enemy patrol panicked, Little wrote. Overwhelmed by Johnson's ferocity, and with the sound of French and American troops approaching, the Germans ran back into the night.

"The raiding party abandoned a considerable quantity of equipment (from which estimate of strength of party is made), a number of fire arms, including automatic pistols, and carried away their wounded and dead," reported the New York National Guard annual report of 1920.

By daylight, the carnage was clear. Even after suffering 21 wounds in hand-to-hand combat, Henry Johnson had stopped the Germans from approaching the French line or capturing his fellow Soldier.

"He killed one German with rifle fire, knocked one down with clubbed rifle, killed two with bolo, killed one with grenade, and, it is believed, wounded others," the National Guard report said.

The French 16th Division, which commanded the Hellfighters, quickly recognized the actions of Johnson and Roberts. The two Soldiers received the French Croix du Guerre, that country's highest military honor.

The French orders, dated May 16, state Henry Johnson "gave a magnificent example of courage and energy."

They were the first U.S. Soldiers to earn this distinction and Henry Johnson's medal included the coveted Gold Palm for extraordinary valor.

From that point on, Pvt. Henry Johnson was known as "Black Death."

The regiment would go on to prove itself in combat operations through the rest of the war, receiving the Croix de Guerre, for its unit actions alongside some 171 individual decorations for heroism.

But Henry Johnson would be singled out for his heroism and actions under fire. Former President Theodore Roosevelt called Johnson one of the "five bravest Americans" to serve in WWI.

The question of whether the African American 15th New York Infantry would fight as well as any other unit was answered in the darkness of May 15, 1918.

After the war, Johnson and Roberts returned home as national heroes. Promoted to sergeant, Henry Johnson led the New York City parade for the 369th in February 1919.

Johnson's extensive injuries however, prevented his return to any normal civilian life. He had difficulty finding work. He died destitute in 1929 and was buried at Arlington National Cemetery.

Some 97 years after his combat service in France in 1918, the Department of Defense reviewed his records and recommended his Medal of Honor, presented by then President Barack Obama in 2015.

His citation reads "Private Johnson exposed himself to grave danger by advancing from his position to engage an enemy soldier in hand-to-hand combat. Wielding only a knife and gravely wounded himself, Private Johnson continued fighting and took his bolo knife and stabbed it through an enemy soldier's head. Displaying great courage, Private Johnson held back the enemy force until they retreated."

"We are a nation -- a people -- who remember our heroes," Obama said during the June 2015 Medal of Honor ceremony at the White House. "We never forget their sacrifice, and we believe it's never too late to say, 'Thank you.'"
