Dale and Christophe discuss the February 1942 German U-boat attack on Aruba and why the island’s Lago Oil and Transport Company refinery was a critical Allied fuel source, processing Venezuelan crude into high-octane aviation gasoline. They explain Operation Neuland, Germany’s coordinated Caribbean submarine offensive aimed at sinking tankers and crippling oil production, and detail U-156 (commanded by Werner Hartenstein) torpedoing multiple anchored tankers near San Nicolas Harbor, including the USS Pedernales, while attempting to shell the refinery. The shelling effort failed when the crew fired the deck gun with the muzzle cover still on, injuring crew and leaving the refinery largely intact; refinery workers activated emergency systems and production resumed quickly. The episode covers the psychological impact on Aruba, limited early defenses, casualties among sailors, and the broader campaign involving U-502, U-67, and U-129, which disrupted shipping across the Southern Caribbean. They describe the U-boat deck guns (8.8 cm and 10.5 cm) and the purpose of the muzzle plug, discuss convoy expansion, air patrols, blackouts/light discipline, and strengthened Caribbean bases and defenses that reduced U-boat effectiveness by 1943. The hosts emphasize logistics and energy infrastructure as strategic targets, industrial resilience, hemispheric defense cooperation, and how Caribbean oil supported later Allied operations, including aviation over Normandy. The episode ends with a “Hero Card” honoring Specialist Robert E. Hall Jr. of Pittsburgh, Pennsylvania, US Army Reserve 467th Engineer Battalion, killed by a suicide car bomb at a gate in Iraq on June 28, 2005, and provides contact info for the podcast via email, X/Twitter, and Discord.
