The SS Jacksonville was a United States Merchant Marine tanker constructed in 1943 by the Kaiser Shipbuilding Company at the Swan Island Shipyard in Portland, Oregon. As a tanker built during World War II, it played a vital role in maritime logistics, transporting fuel and other essential goods across dangerous waters. The vessel was named after Jacksonville, a town in Jackson County, Oregon. Designed for wartime service, the SS Jacksonville was a significant part of the American merchant fleet, although specific details about its dimensions and tonnage are not provided in the available source. Its construction at the Kaiser Shipyard reflects the rapid shipbuilding efforts of the period, aimed at supporting Allied operations worldwide. The ship's service history was relatively brief and marked by its tragic sinking on August 30, 1944. While traversing approximately 50 miles north of Ireland, the SS Jacksonville was attacked by the German submarine U-482. The U-boat scored two torpedo hits, causing catastrophic damage. Remarkably, even after being broken in half by the attack, the ship refused to sink immediately. The rear section of the vessel remained afloat until it was finally sunk by ships' guns and depth charges from convoy escorts. The forward section of the ship floated for about 15 hours before also sinking. The attack resulted in a tragic loss of life, with only two survivors from the 78 crew members: Marcellus Wegs and Frank Hodges. The SS Jacksonville's sinking illustrates the peril faced by merchant ships during the Battle of the Atlantic and highlights the bravery of the crews operating these vital supply vessels. Its story remains a testament to the wartime sacrifices made by merchant mariners engaged in sustaining Allied efforts during World War II.
