Operation Tidal Wave, the Low-Level Ploesti Raid, and the Five Medals of Honor Won in a Single Mission

On August 1, 1943, the United States Army Air Forces launched Operation Tidal Wave, sending 177 B-24 Liberator bombers on a low-level strike against the oil refineries of Ploesti, Romania. The mission produced five Medals of Honor awarded from a single operation - more than any other American military action in the Second World War. Three of the five decorations were posthumous.

Why Ploesti Was the Primary Target

Ploesti sits in a petroleum basin approximately 35 miles north of Bucharest in southern Romania. By the summer of 1943, its nine major refineries were supplying roughly one-third of all refined petroleum consumed by the Axis war machine - aviation fuel, diesel for Panzer divisions on the Eastern Front, and industrial lubricants. American planners described it as “the taproot of German power.”

The target had been on the Army Air Forces’ radar since 1942. A small probe of roughly a dozen aircraft was flown against Ploesti in June 1942, accomplishing little beyond confirming the target was heavily defended and worth defending. What followed was a year of more deliberate planning.

The Logic Behind a Low-Level Attack

The plan that emerged rejected the conventional high-altitude approach entirely. Flying at treetop level - as low as 50 feet - offered several tactical advantages: the formation might not be acquired by Romanian radar until it was too late to respond, it would fly beneath the effective ceiling of heavy anti-aircraft guns, and bombardiers could use a fixed sight line aimed at a specific building rather than a high-altitude bombsight requiring complex calculations.

The tradeoff was total exposure if the element of surprise was lost.

The five bomb groups assigned to the mission spent months at airfields around Benghazi flying practice runs over the Libyan desert, skimming the sand at fifty feet and striking marked targets that simulated specific refinery structures. Scale models built from intelligence photographs were studied until crews could describe their assigned aiming points from memory.

The Five Bomb Groups Assigned to the Mission

Brigadier General Uzal Ent flew aboard the lead formation as senior air commander. The five groups and their commanding officers:

376th Bomb Group “Liberandos” - led by Gen. Ent, flew the point position
93rd Bomb Group “Ted’s Travelling Circus” - commanded by Lieutenant Colonel Addison Baker
98th Bomb Group “Pyramiders” - under Colonel John Kane, known as “Killer” for his reputation of pressing an attack past the point where most commanders would pull off
44th Bomb Group “Eight Balls” - commanded by Colonel Leon Johnson
389th Bomb Group “Sky Scorpions” - assigned to the Campina refinery complex, north of the main Ploesti fields

The night-before briefing made no attempt to minimize what the crews would face: hundreds of anti-aircraft guns, fighter squadrons on alert at Romanian airfields - and a detail that stood apart. The Germans had positioned some flak batteries at the altitude the attackers would be flying. Those guns would not angle upward into a high formation. They would fire level.

The approach across the Mediterranean and north through the mountains proceeded largely as planned. Then, descending into the Romanian agricultural plains and approaching the final turn toward the target, the lead group - the 376th with General Ent aboard - misidentified a town. The navigator believed the formation had reached its initial point. They were in fact approximately 30 miles short of and south of Ploesti. The formation turned - toward Bucharest.

Lieutenant Colonel Addison Baker, leading the 93rd Group immediately behind, recognized the error, broke radio silence to call the correction, and watched the lead formation fail to turn back. By the time General Ent understood what had happened and reversed course, the scattered groups had lost critical time reorganizing.

Romanian observers had been tracking the formation since it crossed the coast. By the time the B-24s came back around toward Ploesti, the flak crews were at their guns and fighter pilots were already airborne. The element of surprise - the entire operational premise of flying slow and exposed over one of the most heavily defended targets in Europe - was gone.

What the Crews Faced Over the Target

The formation arrived over Ploesti in disorder. Groups came in from different headings, some crossing the flight paths of others. Bomb blasts from the first wave were rising into the faces of aircraft that came after. Smoke from burning refinery structures turned daylight the color of rust. A pilot navigating to his specific aiming point was doing so through a windscreen that might be showing him flame and black smoke instead of the building he had spent weeks memorizing.

The anti-aircraft fire was not bursting above the formation in the familiar puffs of a high-altitude raid. It was coming in horizontally - shells traveling through the formation at cockpit level. Crews could see individual gun crews and the muzzle flash from weapons aimed directly at them.

The Five Medals of Honor

Lieutenant Colonel Addison Baker - 93rd Bomb Group. Baker’s aircraft took engine hits over the outer edge of the target complex, then caught fire along the wing. Running on two engines and trailing flame, he had enough altitude to break off the attack, give his crew room to bail out, or attempt a landing in open farmland. He held the aircraft level, kept the nose pointed at the target, and led his formation over the aiming point until the bombs released. His aircraft went down into the complex below. The decoration was posthumous.

Major John Jerstad - flew aboard Baker’s aircraft that day. Jerstad had already completed his required combat tour and had no obligation to fly this mission. He had been involved in the original planning and volunteered to see it through to the end. He did not survive. Posthumous.

Colonel John Kane - 98th Bomb Group. Kane’s aircraft absorbed multiple hits on the run in, with engines damaged and control surfaces shot through. He was commanding the fourth wave into a target that was fully alert and already burning. He pressed the attack, got the bombs on the aiming point, then nursed a crippled B-24 east and south until the aircraft could go no further and put it down on Cyprus. Kane was alive to accept the decoration.

Colonel Leon Johnson - 44th Bomb Group. Johnson pressed his group through the same conditions, put the bombs on target, and brought his aircraft home. He and Kane stood at the same ceremony to receive the same decoration - the only two of the five recipients who survived to accept it in person.

Second Lieutenant Lloyd Herbert Hughes - 389th Bomb Group, Campina refinery. Hughes was 22 years old. On the run in to the target, a flak fragment punctured his fuel tanks. The fuel struck hot metal and ignited. A pilot flying nearby watched the trail of burning fuel grow behind Hughes’s aircraft through the entire bomb run. Hughes did not turn away. His bombardier dropped the load on the target complex. Hughes pulled off and tried to reach open ground. The fire had taken too much of what was holding the aircraft in the air. It came down short of the river the crew was trying to reach. Posthumous.

The Cost and the Damage

Of the 177 aircraft that departed Benghazi, 53 did not return. Some were lost over the target. Some went into the sea. Some crash-landed in Yugoslavia, where partisan networks sheltered surviving crew members. Some reached Turkey - then neutral - and the crews were interned for months. A handful put down in Sicily, Malta, and Cyprus, their aircraft too damaged to make it home.

More than 500 men were killed, captured, or never accounted for.

The damage to Ploesti’s production was real. Six of the nine target refineries were seriously hit and output dropped sharply. But German and Romanian repair crews worked fast. Within months, production had largely recovered.

What Came After Tidal Wave

The Army Air Forces returned to Ploesti many times. High-altitude raids continued through the fall of 1943 and into 1944, with the Royal Air Force adding its weight. Soviet ground forces pressed in from the east.

In August 1944 - almost exactly one year after Operation Tidal Wave - American ground forces reached Ploesti. What they found was not a functioning refinery complex. It was a ruin.

Whether Tidal Wave was worth what it cost has been argued by historians ever since. The temporary disruption to Axis fuel production, the rapid repair of the facilities, the losses in men and aircraft, and five Medals of Honor won in a single afternoon - those facts can be arranged more than one way, and serious people have arranged them differently.

The B-24’s Place in History

The B-24 Liberator has never occupied the same space in aviation memory as the B-17 Flying Fortress. The Fortress is the aircraft in the paintings on hangar walls. The Liberator tends to appear in the footnotes - despite being built in greater numbers than any other American aircraft of the war.

Operation Tidal Wave is the clearest answer to what the B-24 and its crews were capable of. The record of five Medals of Honor from a single mission has not been matched by any other American operation in the Second World War. The primary historical account is Leon Wolff’s Low Level Mission (1957), still considered the standard reference on the Ploesti raid, supplemented by mission records from the Air Force Historical Research Agency’s Mediterranean theater files.

Key Takeaways

Operation Tidal Wave launched on August 1, 1943, sending 177 B-24 Liberators from Benghazi on a 2,700-mile round-trip, low-level strike against the Ploesti oil refineries - then supplying roughly one-third of Axis refined petroleum.
A navigational error over Romania eliminated the element of surprise before the formation reached the target, forcing crews to attack a fully alerted, fully defended complex.
Five Medals of Honor were awarded from a single afternoon - more than any other American operation in World War II. Three were posthumous: Addison Baker, John Jerstad, and Lloyd Hughes. Two recipients, Kane and Johnson, survived to accept the decoration in person.
53 of 177 aircraft were lost and more than 500 men were killed, captured, or unaccounted for. Six of nine target refineries were seriously damaged, but Axis production recovered within months.
The B-24 Liberator was produced in larger numbers than any other American aircraft of the war yet remains underrepresented in popular aviation history. The record of August 1, 1943 is the definitive measure of what the aircraft and its crews achieved.
