The Vessel and Her Loss

SS William H. Machen, a 1916-built steel freighter of the Pocahontas Steamship Company, collided with the British freighter Maid of Stirling east of White Island in the Isles of Shoals on July 7, 1942. Maid of Stirling survived and reached port, but Machen was mortally damaged and sank, becoming one of dozens of U.S. merchant losses recorded that wartime month. The wreck went unlocated for 75 years until a team of technical divers found her lying on her side in 300 feet of water in 2017, confirming her identity from recovered dishware and a ship's clock.
