Operation Tidal Wave and the five Medals of Honor won in one afternoon over Ploesti

On August 1, 1943, the U.S. Army Air Forces launched Operation Tidal Wave - sending 177 B-24 Liberators at fifty feet above the Romanian countryside into the oil refineries of Ploesti. Five Medals of Honor were awarded for that single mission. That is more than have ever been awarded for any other American military operation, before or since.

Why Ploesti Was the Most Important Target in Occupied Europe

The refineries of Ploesti, Romania, produced an estimated 35 percent of Germany’s refined oil in 1943. Tanks, aircraft, warships, and the entire motorized Wehrmacht ran on petroleum that flowed, in enormous part, out of that one valley. Allied planners understood that strangling Germany’s fuel supply meant hitting Ploesti - and hitting it hard.

Romania was an Axis ally, not occupied territory, which meant the Germans had been free to harden its defenses without restraint. Anti-aircraft guns, fighter airfields, and radar networks turned the region into one of the most heavily defended target areas in Europe. The Germans knew exactly what Ploesti was worth.

A previous American raid in June 1942 - thirteen B-24s at high altitude - barely scratched the surface, lost five aircraft, and taught the Germans what to prepare for. They spent the next year making Ploesti nearly impenetrable.

The Plan: Go In Low

By the summer of 1943, planners at 9th Air Force had settled on an unconventional approach. High-altitude bombing had failed to do meaningful damage. The answer, in theory, was to deny the defenses their advantages: fly below radar coverage, below the effective trajectory of heavy anti-aircraft guns, at treetop level and high speed.

The plan required precision navigation across more than 2,000 miles round trip from Benghazi, Libya - right at the operational limit of the B-24 Liberator. Crews loaded extra fuel into bomb bay tanks, which meant they had to burn down to tactical weight before bombs could even be armed. The entire flight out was a fuel management problem.

Five bomb groups were assembled: the 376th, 93rd, 98th, 44th, and 389th. They would launch before dawn, fly north across the Mediterranean, cross the coast of Greece, thread mountain passes through Albania and Yugoslavia, and descend into Romania for the low-level strike.

When the Mission Began to Unravel

The first serious problem arrived before the formation ever reached Europe. One of the lead navigators went down over the Mediterranean - not over enemy territory, over open water. The navigational expertise for a precision low-level strike was suddenly gone.

The formation pressed north anyway. After eight or nine hours of flight, with fuel state weighing on every pilot, the carefully coordinated plan fractured at the critical moment. The 376th and 93rd Groups got separated from the others. They reached the navigational waypoint where the final turn toward Ploesti was supposed to begin - and turned toward Bucharest instead. By the time the error was caught and corrected, two groups were approaching Ploesti from one direction and three from another, at different times, at different altitudes.

The defenses were fully manned and waiting. Whether radar had picked up the formation despite the low altitude or word had come by other means, the element of surprise was gone. Smoke was already rising from Ploesti when the trailing groups could see it from miles out - the early arrivals had already dropped their bombs and triggered fires.

Every crew now faced the same reality: the mission was compromised, the target was burning, and the defensive network ahead had been built specifically to engage aircraft at exactly fifty feet.

Not one crew turned back.

What the Defenses Looked Like From Fifty Feet

Intelligence reports had warned that Ploesti’s defenses were extensive. Reality was worse. Anti-aircraft guns were mounted on the rooftops of refinery buildings and in specially constructed towers woven throughout the complex. Romanian and German fighter aircraft orbited above.

The detail that defined the mission’s horror: flat-cars on the railroad tracks throughout the area, armed with guns calibrated to engage aircraft at fifty feet. The Germans had anticipated a low-level attack. They had built their entire defensive scheme for it, pre-positioning rolling artillery platforms at exactly the altitude the B-24s would be flying.

The Liberators flew in anyway, bomb bay doors open, through smoke thick enough to navigate by feel.

The Five Medals of Honor

Colonel Addison Baker led the 93rd Bomb Group in his aircraft, Hell’s Wench. On the approach to the target, his B-24 was hit and caught fire. He had enough altitude to pull up. He had time for his crew to bail out.

Baker held Hell’s Wench level and on course, leading his formation through the target with the aircraft burning around him, until it went down on the far side of the complex. His co-pilot, Major John Jerstad, held the aircraft with him. Neither survived. Both received the Medal of Honor - posthumously.

Second Lieutenant Lloyd Hughes, flying with the 389th Bomb Group, took a hit on the approach that ruptured a fuel tank. Fuel was streaming from the aircraft. The engines were hot from hours of flight. The ground was fifty feet below. His bombardier reported the bombs had not yet been released.

Hughes was 22 years old. He held the aircraft straight and level through the target, streaming fuel, until the bombs were away and his crew had a fighting chance to survive what came next. The fire reached the tanks before he cleared the refinery complex. Medal of Honor - posthumous.

Colonel John “Killer” Kane led the 98th Bomb Group - his crews called themselves the Pyramiders. His aircraft was hit repeatedly on the bomb run, engines damaged, hydraulics gone. He held his formation together through the smoke and fire and the chaos of simultaneous approaches from conflicting directions. Kane coaxed his crippled Liberator all the way to Cyprus and got his crew on the ground alive. He was there to accept his Medal of Honor.

Brigadier General Leon Johnson commanded the 44th Bomb Group, the Eight Balls. His group reached their assigned target to find it already engulfed - fires exploding through the complex, smoke columns rising higher than a B-24 could safely climb. Johnson led his formation through the flame and wreckage anyway. Medal of Honor.

Three of the five were awarded posthumously. All five were awarded for the same ninety-minute mission over the same burning valley on the same August afternoon.

What Operation Tidal Wave Actually Accomplished

The Ploesti refineries were damaged. Several facilities were put out of operation. But the Germans had engineered redundancy into the system, and repairs proceeded faster than Allied intelligence projected. By fall 1943, Ploesti was back near its previous output levels.

53 aircraft were lost. Hundreds of men were killed, captured, or listed as missing. The target was operational again within weeks.

The straightforward accounting is stark: the mission did not shut down Germany’s oil supply, and the cost in aircraft and crew was enormous. Whether Tidal Wave was a strategic success remains contested among historians. What is not contested is what the crews were asked to do, and what they chose to do when the plan fell apart beneath them.

They were asked to fly into a defended target at an altitude where enemy gunners could see their faces in the cockpit windows. They were asked to do it with navigation already compromised, against a defensive network specifically engineered to destroy them at exactly the altitude they were flying, through fires started by the groups ahead. Every crew knew the odds before they crossed the initial point.

They flew in because the wingman beside them was pressing on. You did not break formation when your wingman was holding course.

The B-24 Liberator’s Place in History

The B-24 Liberator has never received the cultural recognition given to the B-17 Flying Fortress. The B-17 got the films, the memoirs, the nostalgia. The Liberator was described as ugly by the people who flew it - high wing loading, twitchy at slow speed, a reputation for catching fire.

The numbers tell a different story. More than 12,000 B-24s were built - more than any other American combat aircraft of the war. They flew more combat sorties in World War II than any other American aircraft. They flew the Hump over the Himalayas. They flew antisubmarine patrols over the North Atlantic. They served in every theater.

On August 1, 1943, 177 of them flew at fifty feet into Ploesti.
