In 1944, U.S. Bombers Blasted Nazi Troops — And Accidentally Killed Scores of Americans

History, Europe

One of the worst friendly-fire incidents in the history of the U.S. Army. 

Allied troops spent six bloody weeks stuck in dense hedgerows of Normandy after the D-Day landings, fighting the German Wehrmacht one cow pasture at a time. U.S. Army general Omar Bradley cooked up a plan to break through the German defenses by calling upon the heavy four-engine bombers of the 8th Air Force.

What followed was one of the worst friendly-fire incidents in the history of the U.S. Army — and one of its greatest military victories.

The D-Day landings on June 6, 1944 in Normandy are famous for being one of the costliest military operations in American history. What’s less appreciated is that the following two months of combat in the farmlands of Normandy were just as nightmarish.

The problem was the terrain. Farmers in Normandy divided up their pastures with tall hedgerows called bocage that were impassible to most vehicles. Even though the Allies possessed tremendous numerical superiority and greater mobility due to their vast motor pool, the hedgerows forced them to fight in one short range ambush after another through predictable corridors — a tremendously advantageous situation for the defending German army.

Deadly MG.42 machinegun nests and portable Panzerfaust anti-tank weapons defended each field, backed up by pre-registered mortar and artillery bombardments.

Allied tanks attempting to advance up the narrow country lanes had to contend with well-concealed anti-tanks guns and German armor, including Tiger and Panther tanks with frontal armor nearly impenetrable to most Allied tank guns.

U.S. troops sustained some of the heaviest casualties in the war in Normandy, advancing just a few hundred meters a day. Some U.S. divisions took greater than 100-percent casualties — but they avoided bleeding out through a steady flow of inexperienced replacements.

The Americans nonetheless managed to slowly creep forward over the course of six weeks at tremendous cost — 39,000 killed or wounded by the end of June alone.

The Allies’ greatest advantage was air superiority — swarms of American fighter-bombers roamed over Normandy, largely unopposed by German fighters, devastating German units attempting to move in daylight. American troops also called on them to take out enemy strongpoints and tanks — but often battles in the bocage were fought at such short ranges that it was unsafe to call in air support.
