U.S. LIFE-SAVING STATION BUILT IN 1902. IN JUNE 1942 GUARDSMAN JOHN CULLEN DISCOVERED FOUR GERMAN SABOTEURS ON THIS BEACH. WILLIAM G. POMEROY FOUNDATION 2018
The Story
This beach began as a U.S. Life-Saving Station built in 1902, part of the network of rescue crews who watched the dangerous Atlantic shore. Its most dramatic moment came in June 1942, when Coast Guardsman John Cullen, walking a foggy nighttime patrol, encountered four German saboteurs who had just come ashore from a U-boat. His report set in motion the manhunt that captured them — a rare enemy landing on American soil during World War II.
Why it matters
It marks one of the few places where the Second World War literally reached the U.S. mainland, a stark reminder that the home front's vigilance mattered.
The story behind this marker
AI contextThe era
This stretch of Long Island's Atlantic shore has always faced the open ocean, and long before the war it belonged to a quieter kind of service. In 1902 the government raised a U.S. Life-Saving Station here, one of a chain of outposts strung along a dangerous coast. Their crews watched the surf for ships in trouble and pulled sailors from the breakers — the same lifesaving tradition that would later fold into the U.S. Coast Guard.
By the summer of 1942 the country was half a year into the Second World War, and the Atlantic was no longer just a hazard of weather and wreck. German U-boats prowled close to the American coast, sinking merchant ships within sight of the beaches. The eastern seaboard had gone to blackout and beach patrol, and quiet resort towns like those of eastern Long Island found themselves on the front edge of a global war.
Against that backdrop the old station kept its watch, only now the danger might come not from the sea's storms but from the enemy riding beneath it.
People & events
On a fog-wrapped night in June 1942, a young Coast Guardsman named John Cullen was walking his patrol along this beach when he came upon four men who had just emerged from the darkness of the surf. They had landed from a German submarine, put ashore to carry out sabotage on American soil.
Cullen was unarmed and badly outnumbered, and the encounter was tense and strange in the dark. But he made it back to report what he had seen, and his report was the thread that unraveled the whole operation. What began as a shadowy landing on a lonely beach became a full-scale hunt by federal agents.
The would-be saboteurs, who had come ashore expecting to slip unseen into the country, were instead tracked down and taken into custody. A plot meant to strike at America from within collapsed almost as soon as it touched the sand — undone, in no small part, by one guardsman doing his ordinary job on an extraordinary night.
Its place in the American story
For all the vastness of the Second World War, remarkably little of it ever touched the American mainland directly. This beach is one of the rare places where it did — where enemy agents actually set foot on the continental United States and the war stopped being something happening only overseas.
The episode became a lasting reminder of why the home front's vigilance mattered. Blackouts, beach patrols, and lone watchmen on the sand could feel like theater far from the fighting, until a night like this one proved they were not. The whole apparatus of coastal defense justified itself in a single encounter.
It is also a very American kind of story: not a general or a battleship, but a young man on foot who noticed something wrong and reported it. The nation's security, in that moment, rested on ordinary alertness — and it held.
If you visit
Come here and the first thing you'll feel is how exposed this shore is — the Atlantic runs unbroken to the horizon, and on a gray, foggy day it's easy to imagine how much the night could hide. Stand where the sand meets the surf and picture a single figure walking the waterline in the dark.
The marker itself is a compact tribute, the kind you might walk past without knowing what happened here. Take a moment to let the contrast sink in: a peaceful beach that was, for one night, a doorway the war tried to open.
It fits naturally into a day of exploring the East End of Long Island, where the beaches and old maritime stations trade quiet scenery for surprisingly deep history. Bring a windbreaker, walk the shoreline, and let this be the stop where a stretch of sand turns out to hold a story far larger than itself.

United States Maritime Service Officers School
New London, CT
During World War II, New London became home to the largest United States Maritime Service Officers School, where roughly 15,000 officers were trained to command the merchant ships that carried troops, fuel, and supplies across dangerous seas. The U.S. Maritime Service prepared the officers of the merchant marine, whose convoys were vital — and perilous — lifelines to Allied forces overseas. This monument marks the site of that wartime training effort.

At Groton, Connecticut — the historic home of America's submarine force — this memorial centers on an actual submarine conning tower and honors the 3,617 submariners lost during World War II. Fifty-two engraved granite stones ring the site, one for each U.S. submarine that never returned from patrol. The submarine service suffered the highest casualty rate of any branch of the U.S. armed forces in the war.
