Lost During Ploesti Raid, Liberator Gunner Finally Flying Home

January 7, 2023Carl Prine

Tech. Sgt. Harold Kretzer died during the bloody 1943 raid on the oil refinery complex at Ploesti, Romania, but on Jan. 6, 2023, the the Defense POW/MIA Accounting Agency announced that his remains had been identified and he'll be buried in Illinois. Coffee or Die Magazine composite.

He never returned from the bloody 1943 raid on the Ploesti oil fields, but Tech. Sgt. Harold Kretzer is finally flying home to Illinois.

On Friday, Jan. 6, the Defense POW/MIA Accounting Agency announced that the remains of the 32-year-old gunner-engineer in the “Flying 8-Balls” of the 66th Bombardment Squadron (Heavy), 44th Bombardment Group (Heavy), 8th Air Force, had been identified by federal researchers four months earlier.

Military officials said he’ll be buried in Springfield, but no date has been slated.

On Aug. 1, 1943, Kretzer’s B-24D Liberator bomber flew more than 1,000 nautical miles from its Libyan airfield in dusty Benghazi, riding low over the island of Corfu and then through the Pindus Mountains, under strict radio silence and without fighter escort, to emerge at the sprawling petroleum refining complex at Ploesti, just north of the Romanian capital of Bucharest.

Some planes were no more than 20 stories in the sky when they aimed for the oil storage tanks, part of the Operation Tidal Wave plan to surprise the defenders.

But they weren’t surprised.

German code-crackers knew they were coming, and the Luftwaffe had ringed the refineries with anti-aircraft batteries, smoke generators, and balloons tethered with sharp wires, which were designed to slice through a bomber’s aluminum wings.

Flak slashed into the bomb loads of two nearby Liberators, and the shrapnel from their detonations tore into Kretzer’s B-24D, the plane they called “Wing Dinger.”

Two of the Liberator’s aircrew bailed out, but six rode it down to their deaths.

And Wing Dinger became one of the 53 bombers lost during a raid later dubbed “Bloody Sunday” by some, "Black Sunday" by most others.

Like 79 other bomber crewmen, Kretzer’s body couldn’t be identified, so Romanians buried his remains in the Hero Section of Bolovan Cemetery.

After the war, personnel from American Graves Registration Command dug up the remains there and sent them to either the Ardennes American Cemetery or the Henri-Chapelle American Cemetery for burial in Belgian soil.

In 2017, the Defense POW/MIA Accounting Agency began exhuming the unknowns who died during Operation Tidal Wave, and then sent what was left to the federal laboratory at Offutt Air Force Base in Nebraska to try to figure out who they were.

At Offutt, scientists from the Defense POW/MIA Accounting Agency and the Armed Forces Medical Examiner System used bone, tooth, and mitochondrial DNA (mtDNA) and Y chromosome DNA (Y-STR) analysis to identify Kretzer.


On Friday, Jan. 6, 2023, the Defense POW/MIA Accounting Agency announced that the remains of Tech. Sgt.

On Aug. 23, 2022, they officially declared him found.

Kretzer’s name is stenciled on the Tablets of the Missing at the Florence American Cemetery, an American Battle Monuments Commission site in Impruneta, Italy.

But now workers will affix a rosette next to his name, telling mourners that he’s been identified.
