On February 16, 1942, at 1:30 a.m., the first explosion struck the coast of Aruba. The British tanker Oranjestad burned, and the sea became a “river of fire.” World War II had arrived in the Caribbean.
Aruba today is known for white-sand beaches and luxury resorts. But during World War II, this small Dutch island was a strategic linchpin in the Allied war effort, home to one of the largest oil refineries in the world. The Lago refinery processed Venezuelan crude into gasoline for Allied planes and ships, making Aruba a target. German U-boats attacked, a freighter was scuttled in Malmok Bay, and hundreds of foreign nationals were interned in schoolhouses. Yet much of this history remains little known, even to frequent visitors. This article investigates what happened in Aruba during WWII, where the key sites are, and why the story matters.
Aruba played a critical role in WWII as a fuel supplier for the Allies, which made it a target for German U-boat attacks. The island saw the scuttling of the German freighter Antilla, the internment of over 200 German, Austrian, and Italian nationals, and a direct attack on its refinery in February 1942. The story is complex — involving colonial tensions, civilian hardship, and a homegrown resistance hero — and is still not widely commemorated on the island.

Why Aruba Mattered: The Lago Refinery and Allied Strategy
Aruba’s importance in WWII stemmed from one thing: oil. The Lago refinery, built in the 1920s by the Lago Oil & Transport Co. (a subsidiary of Standard Oil), processed crude oil from Venezuela’s Lake Maracaibo. By the late 1930s, it was one of the largest refineries in the world, producing high-octane gasoline essential for Allied aircraft and naval vessels. The refinery’s output was so critical that the Dutch government-in-exile and the United States both prioritized its defense.
In 1939, even before the Netherlands entered the war, Dutch authorities began preparing defenses. A coastal battery was installed at Juana Morto to cover the refinery and the surrounding coastline. Anti-aircraft guns were positioned, and blackout measures were enforced to make the island less visible to enemy ships and submarines at night. In July 1940, 180 French marines landed to bolster defenses, later replaced by English and Scottish troops. The Volunteer Korps Aruba (V.K.A.) handled local security.
After the United States entered the war in December 1941, American soldiers arrived to reinforce the garrison. The airport runway was extended and repaved to accommodate heavy bombers, and the main road from Oranjestad to San Nicolas was relocated to make way for the expanded airfield. These infrastructure changes reshaped the island’s geography in ways that persist today.
A common misconception is that Aruba was a passive bystander in WWII. In reality, the island was an active military target and a vital supply hub. The attack on February 16, 1942, was not a random incident but part of a coordinated German campaign — Operation Neuland — aimed at disrupting Allied oil supplies across the Caribbean.
The Scuttling of the Antilla: A Shipwreck with a Story
One of the most visible remnants of WWII in Aruba is the wreck of the Antilla, a 400-foot German freighter that rests on its port side in Malmok Bay, about 60 feet underwater. The ship had set off on its maiden voyage in the spring of 1939, but after receiving coded “Essberger” signals, it was ordered to return to Germany. By August 31, 1940, it sought refuge in neutral Aruba.
When Germany invaded the Netherlands on May 10, 1940, Dutch authorities declared martial law and moved to seize German ships in Aruban waters. Dutch marines attempted to board the Antilla at 3:10 a.m. Captain Schmidt refused, buying time for his crew to open the seacocks and set fires throughout the vessel. The ship sank a few hours later. The 35 crew members were arrested and joined 185 other German merchant marines in a POW camp, first on Bonaire and later in Jamaica, where they remained until 1945.
Some accounts claim the Antilla was scuttled by a “snap” caused by boiling boilers, but historian Renwick Heronimo and other researchers have debunked this. The sinking was a deliberate, controlled scuttling. Today, the wreck is one of the Caribbean’s most popular dive sites, hosting hawksbill sea turtles, moray eels, blue tangs, angelfish, parrotfish, and damselfish. It serves as both a historical landmark and a thriving artificial reef.
If you plan to dive the Antilla, book with a local dive operator who knows the site’s currents and entry points. The wreck is best visited in the morning when visibility is highest. Bring a dive light to explore the interior compartments — but never enter without proper training and equipment.
Operation Neuland: The Attack on Aruba
The most dramatic moment of Aruba’s WWII history came on February 16, 1942, when German submarine U-156 surfaced off the coast and launched a coordinated attack as part of Operation Neuland. At 1:30 a.m., the first explosion struck — likely a missile aimed at the Lago refinery. The British tanker Oranjestad was hit and burned, its crew killed. The Venezuelan tanker Pedernables was also torpedoed and sunk. A 156 mm dud torpedo was later found onshore near the Arend refinery.
Eyewitness accounts describe the sea turning into a “river of fire” as burning oil spread across the water. Clyde Harms, who was 10 years old in 1942, later recalled the terror of seeing a submarine near his school and the fear of a Nazi invasion. The attack prompted the installation of additional artillery positions at Seroe Colorado lighthouse and Seagrape Cove. A Dutch bomb prematurely exploded during these defensive preparations, killing four officers.
Historian Renwick Heronimo has noted that WWII remains one of the largest calamities in Aruba’s history, yet it is poorly remembered. The attack lasted only a few hours, but its psychological impact on the island’s small population was profound. Food and water supplies became precarious after 1942 due to the increased military presence and shipping losses in the Battle of the Atlantic.
Boy Ecury: Aruba’s Resistance Hero
Not all of Aruba’s WWII story happened on the island. Segundo Jorge Adelberto “Boy” Ecury was born in Aruba in 1922 and moved to the Netherlands for education. When the Nazis occupied the country, he joined the Dutch resistance, participating in sabotage operations and helping downed Allied pilots escape. He was captured by the Gestapo in July 1944 and executed in November 1944 at the age of 22.
After the war, his body was returned to Aruba and buried with full military honors in April 1947. A monument in his honor stands in Oranjestad, and his story is taught in Aruban schools. Ecury is one of the few Aruban figures from WWII whose name is widely recognized on the island, though his story remains less known internationally.
How the War Changed Aruba’s Landscape
The physical traces of WWII are still visible across Aruba, though they require some effort to find. The coastal battery at Juana Morto is now a quiet park with remnants of gun emplacements. The extended airport runway — built to accommodate heavy bombers — is still in use today as Queen Beatrix International Airport. The relocated main road from Oranjestad to San Nicolas follows the route carved out during the war.
The Antilla wreck is the most accessible and popular site, drawing divers and snorkelers year-round. But other locations, such as the artillery positions at Seroe Colorado lighthouse and the site of the internment schoolhouses, are less marked. Local historians and tour operators occasionally offer WWII-focused tours, but there is no centralized museum or interpretive center dedicated to this period.
| Site | What Remains | Accessibility | Best For |
|---|---|---|---|
| Juana Morto battery | Gun emplacements, foundations | Public park, easy access | History walk, photography |
| Antilla wreck | Intact shipwreck, marine life | Dive/snorkel only, requires boat | Diving, snorkeling, marine biology |
| Seroe Colorado lighthouse | Artillery positions (overgrown) | Limited, requires guide | Off-trail exploration |
| Internment schoolhouses | Buildings repurposed, no markers | Not publicly identified | Research only |
Many online sources repeat the myth that the Antilla was sunk by a “snap” from boiling boilers. This is incorrect. The ship was intentionally scuttled by its crew. If you hear this story from a tour guide, it’s worth politely noting the historical record — but also recognizing that local legends often carry their own cultural weight.
Why This History Matters Today
Aruba’s WWII story is not just a footnote. It reveals how a small island became entangled in global conflict through its natural resources, how colonial authorities managed a multi-ethnic population under martial law, and how the war’s physical remnants — a shipwreck, a runway, a relocated road — continue to shape the island’s geography and tourism economy. The fact that this history is not widely commemorated speaks to broader questions about how small islands remember (or forget) traumatic events.
For travelers, visiting these sites offers a chance to engage with Aruba beyond the beach. The Antilla wreck is a world-class dive that combines history with marine ecology. The Juana Morto battery provides a quiet spot for reflection. And the story of Boy Ecury reminds us that resistance took many forms, even far from the front lines.
- Aruba’s Lago refinery was a critical Allied fuel source, making the island a strategic target.
- The Antilla was intentionally scuttled, not destroyed by a boiler explosion — a common myth.
- Operation Neuland in February 1942 brought the war directly to Aruba’s shores.
- Boy Ecury, an Aruban resistance fighter, was executed by the Nazis in 1944.
- WWII sites are accessible but not heavily promoted; seek out local guides for deeper context.
