In 1945, on a ridge in Okinawa, a young American medic named Desmond Doss climbed back into a battlefield that everyone else had retreated from.
No weapon. Just rope and bandages.
He lowered 75 wounded soldiers to safety. One by one. Through the night. Through enemy fire.
His story — told in the film Hacksaw Ridge — is one of individual courage.
But there is another story running parallel to his.
A story not of one man saving lives on one ridge — but of an entire system, built over a century of war, that ensured those lives could be saved once they reached the bottom.
That system is blood transfusion medicine.
And almost every major innovation in it was born not in a research lab — but on a battlefield.

Peacetime Complacency. Wartime Necessity.
Here is an uncomfortable truth about healthcare systems globally:
Blood transfusion medicine gets just enough attention in peacetime. Just enough funding. Just enough urgency. The system works — barely — and no one asks too many questions.
Then war comes.
Suddenly there are thousands of casualties with penetrating injuries, open fractures, blast wounds, traumatic amputations, and internal bleeding. Soldiers who cannot be transported to a city hospital. Soldiers who will be dead in minutes without blood.
And every single time this has happened in history, the blood transfusion system has been forced — out of sheer desperate necessity — to take a leap forward that peacetime never demanded.
Let us go through that journey. War by war.
Blood Transfusion was in the dark till blood groups were discovered by Karl Landsteiner in 1901.
World War I (1914–1918) — The Birth of the Blood Bank
Before World War I, blood transfusion was a direct, vein-to-vein procedure.
A donor lay beside the patient. Blood passed immediately from one body to another. There was no way to store blood, no way to test it in advance, no way to prepare for mass casualties.
When WWI began, the scale of injuries overwhelmed everything. Artillery and shrapnel alone caused over 60% of casualties. Soldiers were bleeding out faster than the system could respond.
The first breakthrough came from Belgian doctor Albert Hustin, who demonstrated in 1914 that sodium citrate could prevent blood from clotting — making it possible, for the first time, to collect blood in advance and store it briefly.
Canadian doctor Dr. Lawrence Bruce Robertson took this to the front line. On the Western Front, he began performing indirect transfusions — drawing blood into a syringe first, then transfusing. A small technical step, but a massive conceptual shift. Blood no longer had to travel directly from one human body to another in real time.
Then came Captain Oswald Hope Robertson of the US Army Medical Corps, who built the world's first blood depot in France in 1917. An ice chest. Glass bottles of O-negative blood, preserved with sodium citrate anticoagulant, packed in straw inside ammunition boxes.
Crude. Cold. Imperfect.
But it was a blood bank.
For the first time in history, blood was waiting for the soldier — not the other way around.
The Spanish Civil War (1936–1939) — Blood on Wheels
A stationary blood bank solved one problem and created another.
The battlefield moves. The injured soldier cannot always be transported to a fixed facility. He is bleeding in a field, on a hillside, in a rubble-filled street.
The Spanish Civil War solved this.
Spanish physician Dr. Frederic Durán-Jordà, working out of Barcelona, built the first organized civilian blood donor registry in history — collecting, testing, and preserving blood at scale for military use. The Republican Army blood service registered 28,900 civilian donors. The Nationalist service, on the other side of the same war, transfused an estimated 25,000 times before the conflict ended.
But the most iconic innovation of this war came from Canadian doctor Norman Bethune, who volunteered with the International Brigade. Bethune outfitted a van as a mobile blood service. He recruited civilian volunteers as donors, organized rapid transport of type O blood, and drove directly into the war zone.
In one year, his unit collected and processed over 340 litres of blood delivered to front-line hospitals.
The mobile blood bank was born.
Blood was no longer just stored. It was moving. Toward the patient.
World War II (1939–1945) — Scale, Plasma, and Preservation
WWII changed the problem from availability to volume and distance.
You couldn't supply entire armies across multiple continents with a van and a few hundred donors. Entirely new solutions were required.
Plasma became the first answer. Unlike whole blood, plasma didn't require blood type matching and could be stored far longer. Dr. Charles Drew pioneered the Blood for Britain program — collecting plasma in the United States and shipping it across the Atlantic to treat casualties of the Blitz in London. His innovations in blood preservation and the bloodmobile concept transformed donation from an emergency act into a public health infrastructure.
Acid Citrate Dextrose (ACD) solution, introduced by Loutit and Mollison in 1943, allowed blood to be stored for significantly longer periods and transported in greater volumes than ever before.
Freeze-dried plasma, developed by the Lister Institute in the UK, could be shipped globally without refrigeration — a logistical revolution for battlefield medicine.
The glass bottle problem — bottles shattering on rough roads and damaged transport — was also confronted during this era, driving the development of more robust storage and packaging solutions.
D-Day alone required advance planning for at least 30,000 pints of group O whole blood.
This was no longer improvised medicine. This was industrial-scale blood logistics.
This is also where Desmond Doss belongs in this story.
The 75 soldiers he carried off Hacksaw Ridge in May 1945 survived not just because of one man's extraordinary courage — but because, by 1945, there was a functioning blood supply system waiting for them. Plasma. Stored whole blood. Trained medics. A chain of care that had been built, war by war, over three decades.
His heroism and the system's evolution arrived at the same moment. Neither alone would have been enough.
Korea and Vietnam (1950–1975) — To the Point of Injury
Even with mobile blood banks and plasma, a critical gap remained.
The time between injury and transfusion was still killing soldiers.
The Korean and Vietnam Wars drove military medicine to push blood further forward — not to field hospitals, but to the point of injury itself.
Portable transfusion kits were developed. Medics were trained to transfuse in combat conditions. Hemostatic agents that rapidly promoted clotting were introduced, buying time for a patient before blood products could arrive.
The philosophy of battlefield medicine underwent a fundamental shift:
Don't wait for the soldier to reach the blood. Bring the blood to the soldier.
This principle — which sounds obvious in retrospect — was a hard-won lesson that took three major conflicts to establish.
Modern Conflicts and the Present Day — Blood as a Strategic Asset
The conflicts in Iraq, Afghanistan, and the ongoing wars in Ukraine and the Middle East have continued to push the boundaries of battlefield transfusion medicine.
Freeze-dried plasma has been reintroduced for modern battlefield use. Tranexamic acid — a drug that reduces bleeding — is now administered on the battlefield as standard protocol. Remote Damage Control Resuscitation (RDCR) has become a formal military medical doctrine.
But perhaps the most striking example of how war forces blood transfusion systems to evolve comes from Israel.
After the 2014 Gaza war, when rockets reached Tel Aviv and nearly struck the national blood center, a decision was made: the existing facility was too exposed, too small, too vulnerable.
The result was the Marcus National Blood Services Center in Ramla — the world's first subterranean, fortified national blood bank.
Built 15 meters underground. Six stories. $135 million. Protected from rockets, missiles, chemical attacks, biological warfare, and earthquakes. Blast doors. Airlocks. Extra-thick concrete walls. Four independent generators. A strategic blood storage vault at its deepest level holding 25,000 units.
It was scheduled to open in October 2023.
On October 7, 2023 — hours after the Hamas attack — the center activated ahead of schedule.
On a single day in early October, it received 5,000 units of donated blood. Five times the normal daily volume. Thousands of civilians stood in lines for hours to donate.
Simultaneously, on the battlefield, the Israel Defense Forces Medical Corps deployed Low Titer Group O Whole Blood on armored vehicles at every combat brigade level — blood at the front line, ready before the surgeon.
A century after the first blood depot was packed into an ammunition box in France, blood was now secured in a missile-proof vault underground and simultaneously moving forward on armored vehicles toward the point of injury.
The wheel had come full circle — and gone further than anyone in 1917 could have imagined.
The Lesson That Medicine Keeps Having to Relearn
Every advance in blood transfusion medicine documented here — anticoagulants, blood banking, mobile units, plasma, ACD solution, portable kits, hemostatic agents, whole blood resuscitation, underground fortified centers — was driven by a crisis that peacetime had not prepared for.
The pattern is consistent across a century:
Peacetime produces complacency. War produces necessity. And necessity rewrites medicine.
The underground blood bank in Israel was not built because of October 7.
It was built before October 7 — because someone studied the previous wars and decided that next time, the system would be ready.
That is the real lesson.
Not that war is the mother of invention.
But that the work of preparation — the unglamorous, underfunded, under-appreciated work of building robust blood systems before the crisis arrives — is what ultimately determines whether courage like Desmond Doss's translates into lives saved.
Blood doesn't wait for the right moment.
The system has to be ready before the moment comes.
