Torpedo Junction: The Hidden War Off America’s Shore and the Heroes Who Fought It

As World War II engulfed the globe in the 1940s, much of the world’s attention was focused on the bloody battlefields of Europe and the Pacific. Yet, unbeknownst to most Americans at the time, a silent and deadly war was also raging shockingly close to home—just miles off the U.S. East Coast. The waters surrounding North Carolina would earn the ominous nickname “Torpedo Junction,” a haunting reminder of how close Nazi Germany came to threatening the American mainland.

And at the center of it all were the brave men and women—some fighting in the skies over Europe, others watching the shores of America—who risked everything to stop Hitler’s advancing shadow.

The War Comes to America’s Coastline

By early 1942, while Allied forces were preparing for the liberation of Europe, the German Kriegsmarine’s deadly U-boats (Unterseebooten) had launched a brutal campaign along the Atlantic seaboard of the United States. Their goal: to cut off Allied supply lines by sinking merchant ships carrying vital materials, fuel, and troops.

These German submarines prowled the Eastern seaboard, lurking in the shadows of cities like Savannah, Wilmington, and Miami, waiting for Allied convoys to pass. In an alarming show of force, U-boats sank hundreds of vessels—sometimes in plain sight of beachgoers.

The U-boats weren’t merely “submarines” in the traditional sense. They were technological marvels of the time: surface-capable warships that could dive to evade detection and surface again to attack using deck-mounted guns or torpedoes. Their presence caused widespread devastation and terror on the American coastline.

Between January 1942 and early 1943, 397 ships were sunk or damaged, with over 5,000 lives lost. One particularly devastating strike occurred on January 19, 1942, when the U-boat U-123 sank the freighter City of Atlanta off Cape Hatteras, North Carolina—killing 44 of its 47 crew members. Hours later, it struck again, hitting two more ships. The waters ran red with war, and the Outer Banks of North Carolina became ground zero for America’s hidden battlefield.

“Torpedo Junction”: A War We Didn’t See

The area off Cape Hatteras and Ocracoke Island was soon dubbed Torpedo Junction due to the sheer number of U-boat sightings and attacks. What many Americans didn’t realize then was that the war had effectively reached our backyard.

To prevent panic, much of this activity was kept classified. The U.S. government feared mass hysteria if the public learned just how vulnerable the coastline had become. Even today, wreckage from the war rests silently beneath the waves. One German U-boat, U-352, lies just 10 miles off the coast of Wilmington, North Carolina, in 120 feet of water, its hatches still sealed—its crew forever entombed in their steel vessel.

America Fights Back: From Air to Sea

The U-boat menace galvanized American military response. Airfields sprang up all along the East and Gulf Coasts, from Tampa, Florida to Dow Field in Maine, housing squadrons of bombers tasked with hunting submarines. The B-24 Liberators, long-range bombers with immense payload capacity, were deployed for anti-submarine patrols. The U.S. Navy and Army Air Forces, along with civilian volunteers, began a relentless surveillance campaign.

By mid-1942, the tide began to shift. On April 14, 1942, the U.S. Navy sunk its first German U-boat in American waters, 16 miles southeast of Nags Head, North Carolina. Over the next few months, three more U-boats were destroyed off the North Carolina coast alone—more than any other U.S. state. The deadly chess game between submarines and patrol planes intensified.

Operation Carpetbagger: Helping the Resistance

As the battle along America’s coast waned, a new and daring mission was born overseas: Operation Carpetbagger.

By late 1943, the French Resistance had become a critical force in undermining Nazi occupation. But they needed help—supplies, weapons, and intelligence support. In response, the U.S. military selected elite aircrews—many from the very same anti-submarine squadrons that had defended the Eastern seaboard—and deployed them to England. From there, they flew covert night missions deep into occupied France.

Using modified B-24 Liberators, they dropped agents, weapons, radio equipment, and even propaganda materials to resistance fighters. These secretive flights, often carried out under heavy fire and in complete darkness, were among the most dangerous aerial missions of the war.

It was called Operation Carpetbagger—and it was a vital turning point in the effort to weaken German command and assist in the D-Day landings.

A Small-Town Hero: Henry D. McMillan Jr.

While brave pilots flew missions above France and submarines lurked offshore, one young man from Teachey, North Carolina, quietly prepared to serve his country.

Henry D. McMillan Jr. grew up in the 1930s in a tight-knit, God-fearing family. His father, a hardworking grocer, had taken over the family store built in 1908. His grandfather, a post-Civil War contractor, had helped build the Teachey Presbyterian Church—a centerpiece of their community.

Even as a child, Henry showed a deep curiosity for life and a fascination with military affairs. A natural leader and a bit of a showman, he balanced his small-town duties with a hunger for something more. By the late 1930s, he was running a jukebox service business, hustling between diners and dance halls.

But adventure called—and when the war began, Henry enlisted to serve. Though the records of his specific military service are sparse, his life mirrors that of many young men whose worlds shifted overnight—from rural towns to foreign battlefields.

The Legacy Beneath the Waves

Today, the shores of North Carolina’s Outer Banks seem peaceful. Tourists walk the beaches, unaware that just beneath the surface lie wrecked freighters, sunken submarines, and the skeletal remains of a war that nearly touched American soil.

Torpedo Junction is more than a nickname—it is a monument to forgotten heroes, hidden threats, and a time when the enemy wasn’t across the ocean, but right at our doorstep.

As we remember those who gave their lives on distant shores, we must also remember the brave souls who defended our own—and the countless families, like Henry McMillan’s, whose sons went from church pews to cockpits in defense of liberty.
