Operation Tidal Wave, the Low-Level B-Twenty-Four Attack on Ploesti, and the Most Decorated Single Mission in American Aviation History

On August 1, 1943, 177 Consolidated B-24 Liberators lifted off from five airfields outside Benghazi, Libya, bound for a target six hundred miles north. The mission was Operation Tidal Wave. By nightfall it would become the most decorated single mission in American military history, with five Medals of Honor awarded for actions on a single day - a record that has never been equaled.

Why Ploesti Was the Target

The city of Ploesti, Romania, sat at the center of the German war machine’s fuel supply. By the summer of 1943, the refineries ringing the city were processing roughly one-third of all petroleum products sustaining German military operations - fuel for armored divisions, the Kriegsmarine, and critically, aviation fuel for the Luftwaffe.

A small precursor raid had been launched in June 1942: thirteen B-24s, minimal damage, and no strategic impact beyond proving the route was flyable. The concept of a larger strike grew from that test, cycling through the code names Operation Statesman and Soap Suds before settling on Operation Tidal Wave.

The Plan: Five Groups, Five Refineries, One Minute

The strategy was precise in concept and brutally demanding in execution. Five bomb groups would fly in below radar and below the minimum depression angle of heavy flak guns, each assigned to one of Ploesti’s five major refinery complexes. All five were to arrive simultaneously, hitting every target before smoke from the first explosions could obscure the approach to the next.

Army Air Forces planners built a full-scale physical replica of the Ploesti refinery complex in the Libyan desert - not a diagram or sand table, but actual wooden frames representing buildings and poles marking smokestacks. Crews flew practice runs over it for weeks, memorizing the visual picture of an approach they would fly once, at low altitude, in hostile airspace.

The five bomb groups assigned to the mission were:

44th Bomb Group - the Eight Balls
93rd Bomb Group - Ted’s Travelling Circus, a veteran unit temporarily detached from the Eighth Air Force in England
98th Bomb Group - the Pyramiders
376th Bomb Group - the Liberandos
389th Bomb Group - the Sky Scorpions

How the Plan Unraveled

Two failures cascaded into catastrophe before the formation reached the target.

First, radio silence was broken en route. A brief transmission warning of a collision hazard was intercepted by German signals units. By the time the formation crossed the Danube into Romanian airspace, the air defense network had already alerted its fighter and flak units. The surprise the entire plan depended on was gone - and the crews did not yet know it.

Second, the lead navigator died earlier in the flight. His replacement, navigating at speed over unfamiliar terrain, confused Targoviste - the designated initial point for the final approach - with Ploesti itself. The 376th group turned south, toward Bucharest. Trailing groups followed. By the time the error was recognized and transmitted by the mission commander, attack corridors were in disarray. Groups converged on the target from multiple wrong headings, arriving simultaneously but not as planned.

What They Found Over Ploesti

Ploesti by August 1943 was among the most heavily fortified targets in occupied Europe. Flak batteries ringed every major processing facility in concentric defensive layers. Barrage balloons were tethered above the highest-value structures. Romanian and German fighter squadrons operated from nearby airfields.

The flak gunners had not set their weapons for high-altitude defense. They had depressed their guns to the horizontal. A low-level attack had been anticipated, and the defensive network had been configured to meet it.

The five groups hit the target area from multiple directions, some flying approach corridors they had never rehearsed, some arriving over refineries already burning from earlier waves. The sky above the refinery complex was black with smoke from ignited oil tanks. Fighters descended from above. Aircraft were exploding in formation. Aircraft were on fire and still flying.

The Five Medals of Honor

Five men received the Medal of Honor for Operation Tidal Wave - more than any other single engagement in American military history, before or since.

Second Lieutenant Lloyd Hughes, 22 years old, was flying with the 389th Bomb Group toward the Steaua Romana refinery complex at Campina, approximately 20 miles northwest of Ploesti. His aircraft took a flak hit on the approach run. Fuel was streaming from a ruptured wing tank, and it was on fire. His crew urged him to break off. Hughes held his heading, flew his burning aircraft through the target, and released his bombs. He attempted to crash-land in a dry riverbed nearby. The aircraft was not survivable. Medal of Honor, posthumous.

Colonel John Riley Kane, known to his crews as Killer Kane for his aggressive flying style rather than any disposition, commanded the 98th Bomb Group. He watched aircraft after aircraft take hits and go down on the approach, pressed through the target, and brought his aircraft back to Libya. Medal of Honor.

Colonel Leon Johnson commanded the 44th Bomb Group and arrived at his assigned refinery to find it already burning from groups that had hit it ahead of him. With the target obscured by smoke, he adjusted his approach under fire, completed the bomb run, and came home. Medal of Honor.

Lieutenant Colonel Addison Baker was commanding the lead aircraft of the 93rd Bomb Group. His copilot that day was Major John Jerstad, who had already completed his combat tour and was eligible to rotate home. Jerstad had volunteered to fly Tidal Wave because he knew the route and wanted to help bring the group through.

Baker and Jerstad’s aircraft was struck by flak and burning before it reached the initial point. They held it level and on heading. They flew through the initial point, through the target area, through the flak and the detonations of the refineries below them, holding the aircraft steady long enough for the following formation to execute their attack runs. The crew did not bail out. When the aircraft went in, everyone was still aboard. Addison Baker: Medal of Honor, posthumous. John Jerstad: Medal of Honor, posthumous.

The Cost and the Aftermath

The formation staggered back to Libya through the afternoon and into the evening, some aircraft diverting to Malta or other Allied fields when fuel ran out. The final accounting:

54 aircraft lost
532 men killed
440 taken prisoner
78 interned in Turkey, a neutral country where they landed and were held
Of the 177 aircraft that departed before dawn, only 33 returned to their home bases undamaged

The damage to Ploesti was real. Several critical processing units were destroyed or put out of action, and German petroleum production took a measurable hit for a period of weeks. But the refineries did not stop producing oil. German repair crews worked around the clock, and within months the complex had largely recovered its capacity.

The Fifteenth Air Force returned to Ploesti more than twenty additional times over the following year - high-altitude raids with fighter escort, methodically grinding away at the target. The refineries were finally closed by the combined weight of those follow-on missions and the advancing Soviet ground forces in the summer of 1944.

The B-24 Liberator and Why It Was Chosen

The B-24 Liberator has never carried the cultural prestige of the B-17 Flying Fortress. Some crews considered it harder to control at low speeds and more prone to fire when hit. Its Davis wing was aerodynamically efficient for range but could fail in ways the B-17’s wing did not.

It was chosen for Tidal Wave precisely because of what made it less celebrated: range. Getting from Benghazi to Ploesti and back was at the outer edge of what was operationally possible, and only the Liberator made the fuel math work. The aircraft’s limitations were real. So was its capability.

Surviving B-24s are genuinely rare today. The cockpit sits high, with large windows designed to give visibility over flat terrain at low altitude. The view through that glass on August 1, 1943 - at 150 feet over Romanian farmland, smokestacks above, every gun in the valley leveled and firing - is a thing that belongs entirely to the men who experienced it.

Key Takeaways

Operation Tidal Wave (August 1, 1943) targeted Ploesti, Romania, whose refineries supplied roughly one-third of Germany’s petroleum products
A navigational error at Targoviste and a broken radio silence destroyed the attack’s coordinated approach, forcing groups to strike from wrong headings into a fully alerted defense
Five Medals of Honor were awarded for a single mission - Lloyd Hughes, John Riley Kane, Leon Johnson, Addison Baker, and John Jerstad - an American military record that stands to this day
The mission inflicted significant but temporary damage; Ploesti was not permanently shut down until high-altitude follow-on raids combined with Soviet ground advances in summer 1944
The B-24 Liberator was selected over the B-17 specifically for its range, which made the Benghazi-to-Ploesti round trip mathematically possible
